Ken: How ya’ll all doing Me: I’m doing horrible Ken: That’s just great!

Everyone gangsta till ken turns the Power MAC G5 into a Power MAC G6

Thanks for the shoutout bud. Glad we could help but not help lol.

Yeah, the liquid-cooled models are notorious for coolant leakage. And they can have issues even if there aren't any obvious signs of leakage, as happened with the G5 Quad I built a few years ago, which started overheating.

Thanks for the shout out bud! And I think it’s be an awesome video if you’d try to fix it 😉

The Powermac G5 and the first waves of Mac Pros are by far the most beautiful things Apple has ever designed and I'm convinced that they never will reach that height again

If you could somehow afford to have it fixed, it would be awesome to watch a video of yours demonstrating the performance of what is the fastest consumer grade PowerPC computer ever made. I really enjoy your videos, man. Cheers from Brazil!

Literally no-one: PowerMac G5: ima be a gun 0:07 Edit: I also love how the camera zooms back right after that *PA* just to add on to the spook factor

Contact the 8 Bit Guy, on KZfaq. He knows a ton about Macs, might be able to help you

Take it from me, G5 disassembly is hell, especially the air cooled models. Prepare to buy the kinds of screwdrivers you usually only see for automotive interior use and to wonder why the PSU has so many metal bits.

it probably went through different pressures during shipping causing the liquid to leak out or fitting to get popped. if it was shipped by air this is a big probability.

8:52 Ken: (casually plugs it in) PowerMac G5: *_No_*

Likely the mains was shorted to ground, and the pop was that current going through the fuse, and likely protecting the computer

Mac: I dont wanna work todayyyy, go awayy Ken: Okay, i think something is broken Me: i think the PSU has blown something up

I swear if I see one more cheese grater on this show.... I'm gonna continue watching because I enjoy the content and the cheese grater is freaking sweet.

Video with a hook at the start that isn’t clickbait? This is the kinda content I appreciate 🙌🏼

I still use a Cinema Display (23 inch) With my 2013 MacBook Pro running macOS Catalina 10.15 public beta using an HDMI to DVI adapter and it’s higher resolution than this Asus monitor I have from 2012. Apple products always last longer and are still sometimes used as primary devices for years after they’re discontinued

5:15 When I heard him say "G5 reactor cores" I kinda freaked out

I love how when it explodes he doesn't pull the cord right away like anyone else would.

“If you see liquid, power off and unplug computer” Me, with a Pepsi in my disc tray: oh shit

Here's something: I once saw a Power Mac G5 in my school like a year or 2 ago.

Well, this blows (haha) Liquid cooled PowerMacs are just awful. I'm kinda glad the model I have has traditional air cooling (only ONE G5 still... that needs a much better graphics card because that FX 5200 is shit...oh and a cinema display) Still, it's sad, you should try that display on something that won't blow up in your face though

Bummer, man! When I emailed you this morning I had no idea it was going to turn out like this. I also had no idea they made a liquid-cooled version! Hopefully you'll find someone in your area who can help you repair it. That's a nice one to have in your collection! I think I like the way the G5s look better on the inside than the Pros; I like that clear plastic.

Before: Stand included After: You expect us to give you a stand for free?

I know you don't want to get the power supply out, but you will have to, or take it to a local repair shop and tell them what happened. You'll want one that specializes in component-level board repair, as if something is messed up royally, they have the skills needed to fix such things. Now if you felt like it, you could talk to Louis Rossmann about it, while he does repair MacBooks for a living, he does seem to know a bit about power supplies from stuff he's mentioned in earlier videos (like repairing audio equipment when he was young). But that's only a suggestion as Louis' shop is in New York.

I have to say it - "Bridge! We've got a coolant leak! We've got a coolant leak down here!"

“It’s hard to fit everything because it’s so big....” .......”oh yeah.....” lol

When you said that this episode was a disaster on the community post, I thought that you were exaggerating. Turns out I was wrong and Krazy Ken was right! Haha! Anyway, I am not knowledgeable in Macs at all, and I don't live in the US so I can't help you, unfortunately. But, I really hope that you can fix it, Ken. Let us know on the next KKTM episode.

Years later, Ken and Hrutkay fixed it. It's back to life.

You will need to re-build the Liquid Cooling System (LCS). Need new hoses, new coolant, and long T-handle hex driver to get it all out. Check Granger for the tool, under $7 and totally worthwhile. Also need new O-rings. Check online for a guide on re-building the LCS. Would make for a cool video! Then (or probably FIRST), open up the power supply to see what need fixed.

Ah yeah, the PowerMac G5. I had the misfortune of owning a Late 2004 Single Core model which as some might remember was the one that never worked properly and would just randomly freeze for no reason. Coming from a PowerMac G3 B&W it was actually quite the beast, at least when it fucking worked instead of freezing in the middle of whatever I was doing -.- That being said, I still love these machines. I even managed to get my hands on a Quad Core model a few years ago where the watercooling apparently hadn't leaked and destroyed the machine yet, but sadly I was still unable to get it to boot - my assumption is that one of the CPU modules is bad. No explosions though, so that's nice! I haven't entirely given up on these yet though, so I might still try and get another one at some point.

I have a mac pro 2.8 this kinda reminded me of. When i plugged it in it SPARKED! Looks completely different inside tho... Also mine had dirt and leaves and stuff in it. It also has a rusted cap on the ram board. It is the 8 core

You confuse cinema display hd and cinema display with eachother, the HD version is the older one and the one you have and the non hd with is higher resolution is called cinema display and is newer and has the psu included inside :)

The difference between a PC and a Mac guy: oh my PC broke... Well I'll fix it. And oh my Mac broke, oh well by the act of God I'll get a new one 🤣

Ken, I recommend plugging PCs/Macs with power outlets like this: To unplug: Turn off in software, flip the switch on PSU, wait couple seconds, unplug from *WALL,* then from the computer. To plug in: Flip switch, plug the cable into PSU (not plugged into the wall YET), then plug into wall and you’re good to go. Hope this helps, because I find this to be the most safe method.

The PM G5 PSU should only ever click when plugged into power, if it clicks at any other point, Duck.

Pop Goes the Power Mac

*laughs at your puny monitor while doing work on the 30 inch variant*

boi do i love when the title has the word DISASTER

12:18 'September 17th, 2004' I was less than a day old when that computer rolled off the production line.

Some interesting trivia about the Apple Cinema Display. It was first introduced in 1999 at 20", then the largest LCD flatscreen monitor available for a computer (There may have been larger CRT monitors available but they would have been very heavy and bulky compared to the Cinema Display). The only downside was that the original 1999 20" Apple Cinema Display cost a whopping $4000. The 1st gen used a DVI connector. With the 2nd ten in 2000, the swished to a proprietary Apple Display Connector (ADC) which carried a DVI video, USB, and power, all via one plug. This meant it was easy to hook up a ADC-based Cinema Display to a Power Mac as it used just one connector and you got a built-in USB hub with your display but with the major downside that you couldn't hook up third-party displays to a Power Mac ADC port without a adaptor nor would a ACD monitor hook up to a PC or Non-ADC port equipped Mac without adaptor. Fortunately, the version of Cinema Display you have has a standard DVI connector as in 2004 they realized their mistake in using the proprietary ADC connector and went back to separate DVI and AC power connections as well as separate connections for built-in UISB and FireWire ports/hubs. The made the 2004 and later versions of the Cinema Displays all Wintel PC compatible. The version of ACD you have ran $1300 for the 20" and $2000 for 23" and a whopping $3300 for a 30" (The largest ACD or Apple display of any sort Apple ever offered). In 2008 they switched to LED backlighting in the Cinema Displays (sold as the LED Cinema Display) sold until 2013. The last display Apple introduced (prior to the just released Apple Pro Display), was the 27" Apple Thunderbolt Display (2011-2016) introduced alongside the LED CD and sold for three more years after the ACD was discontinued.

So this 'thing' you see at 10:06 is actually some padding that sits around or near the power supply (I haven't pulled one apart for some time, so I can't remember where exactly.) Someone has removed and/or replaced the power supply, and has not reseated the power supply properly, thus displacing the padding. This padding is not metal, but some synthetic mesh padding that is throughout PowerMac G5s and Mac Pros, probably to insulate sound or vibrations.

Oh, ken you should talk to "The 8-Bit Guy" to get the PowerMac repaired, hes very talented, also he has almost 1 Millon Subscribers

My PC also had a coolant leak from the corsair pump and the power supply was right below it. Corsair quickly replaced the power supply and graphics card. They sent me a new revision of the pump that seems to have reinforced sleeves so theres that.

I've had PSUs blow up on the bench next to me. One time the receptionist came into the back to ask me a question and shouted "umm, that computer is smoking" It got to where i would just reach over and yank out the power cord without even looking up from the laptop I was neck deep in.

I'm a PC guy but this is one of the most beautiful cases ever made, really nice to take apart too.

Its weird... On minute 8:50 to minute 9:00, the G5 led power light is blinking, eventhough the powerbutton has not been pressed.🤨

8:49 the power light turned on for a bit

During shipping could the liquid have frozen? Such as high altitude unpressurized cargo?

I thought that was a modern computer until you said it was so old!

I love the PowerMac G5/Mac Pro cheese grater design so much

You plugged it in, something’s happened and boom!

You didn't see the warning because, thanks to Jony Ive's brilliance, it was printed in light gray text over a light gray background, and then hidden from view.

I've got a dry G5 PowerMac just sitting in my garage. The system is too old to use day-to-day. I'm still using the Cinema Display as my main monitor. Awesome gear! I moved to a Nehalem PowerMac, but when that crapped out two years ago, Apple gave me a Trash Can Mac. Now I have a spaghetti monster under my desk. The extensibility of the cheese grater Macs was sublime.

Well, easy take it a part, see if the power supply has any visible damages, ,if not clean it all with isopropyl alchool, check the fuses are ok. Then check where the leak is, repair it, top up the coolant and give it a go, if not get another power supply.

That Cinema Display is still better looking and more well-built than any top-of-the-line monitor today..

I bought that exact model new and still have it. Luckily no leaks yet, but I rarely run it because A:The heat could peel the paint off a battleship and B:The seven(!) fans run full blast constantly to try and overcome the tons of dust it has inhaled over the years. I've looked online and getting access to clean the dust out is a nightmare. It's been a good machine otherwise though. Got the display too which works fine but is noticeably dim compared to my iMac 5k.

Lol I know I’m late to the party. Happy to help with this. I have the ability to tear it all down and clean it. I’ve done it once before on a customers tower. Happy to donate my services.

Howdy Ken! I just wanna say that I recently found out that my PowerMac G5 also is a liquid cooled model. It took me way to long to figure that out. So I’m going to spend the day cleaning mine, and maybe even replacing the liquid in the cooling system just to be safe.

At 10:08 it shows that at some point the PSU had been removed and replaced incorrectly, pinching the shielded cable visible there, that is the source of the short. The leaking coolant has been there a while as shown by the accumulated grime (dust mixed with coolant to make a gooey mud). It is likely that by removing the PSU and properly reinserting it after checking for the integrity of the pinched cable the computer should boot up. Eventually there will be enough coolant loss to cause excessive throttling. After playing with it as it is you will find that these make great Hackintosh conversions, bench supports and other creative re-purposing.

As another comment mentioned, unless it was shipped to you via ground shipping, if it was shipped using FedEx Express, USPS Priority, etc it was on a pressurized plane at some point which could have caused issues with the internal pressure of the computers cooling system

Eek! As sweet as the Quad G5's are, heard of many leaking and having weird issues like that. Great machines and an utterly gorgeous design, the G5 towers, just definitely get an air cooled one!

My school uses these as benches

Watching this and seeing how far this channel has come WOW!!

i dont know if anything ever happened with this but maybe try a local electronics repair shop for the psu repair, and put a pair of AIOs on the cpus or ebay a new working cooler for this machine from a later revision, or just turn it into an amazing hackintosh.

My first thought was blown cap because my G5 Dual core 2ghz DID blow a psu cap... About a few inches from my ear. I lost hearing for a week :) apple fixed the power supply under warranty and if I remember right they got recalled for faulty caps. Didn't realize it was a liquid cooled one however

Of note -- only the highest end G5 models are liquid cooled. Most use typical air cooling and very large heat sinks. That being said, oddly enough, the liquid warning is still on the inside of, I think, every single G5! The PSU is a pain to replace, to say the least. It's doable but a chore... I hope I never have to change out one in mine because oh maaaan.... that would be a very long day for me. A fun, but kind of sad, video Ken, in any case. :3

The pump and rad are also made by Delphi I think which makes GM parts (might be owned by GM idk) Mechanics refer to dexcool as dexkill because it destroys intake manifold gaskets lol

looking at the power light when you plugged it in it turned on for a split second and after the kaboom it turned on again for a split second

Ahhhh, the good old liquid cooled powermac G5's.... I have had 4 of these and each one of them had a leak.

Get any other model of G5 to toy around with. The older single processor machines had air cooling, and the later dual and quad core machines had either air or superior liquid cooling that was not as likely to spring a leak. I have had G5s for about as long as G5s have existed, and while I've seen some failures, I've never had a leaky liquid-cooled model. My best one today is a late 2005 G5 (the only models with DDR2 and PCIe!) that was originally a 2.0 GHz dual core system, but I upgraded it with a 2.5 GHz module from a broken quad core system, so now it's a dual 2.5, a configuration that Apple had never originally offered.

this is a common failure. there was a recall apple did and supposedly changed the coolant but i guess this one never got fixed.

There's a reason GM Dexcool is called Dex-kill. It eats silicon based seals alive, hence the reason it's common to have to change Low Intake Manifold gaskets on a lot of the 1996+ V6 (especially the 4.3L found in the second gen S10 Blazers) and V8 engines.

amazing i never knew that apple sold liquid cooled Mac's

DEXCOOL?! Friggin DEXCOOL?!

I'm a mechanic and we call it DexKILL. Replace that stuff with something less corrosive and gel-like.

I almost bought one of these at a thrift store, I'd never seen anything like it. $50, but someone bought it ahead of me. What a design!!

I love how apple put the power supply below the water cooling tank. Even worse the coolant is corrosive... They dropped a ball of lead on their feet when making this.

You could try to repair it yourself. That spark sound and the light from the power supply comes usually from a burned fuse. You could try to replace that fuse with another one with the same values. If it's socketed, good to you, if it's soldered, you must use the soldering iron. And of course, clean any liquid inside the power supply. Good luck!

the SECOND anything blows in a pc or tech device, rip the power out by any means necessary!! im an IT tech and believe me, leaving the cable in, can and will cause a fire!

Man, I'm gutted this video finished before the main event! I remember reading about those back in 2005, when my parents got our first Mac and thinking it was wild - turns out I was right! 🤣🤣

I own 2 G5's and love them. I have 1 dual core and 1 quad core both late 2005. These G5's are louder than a house fan when they are cooling. When I bought one of mine, when you turned it on it did not make the apple chime at startup. It turned out that one of the two memory cards was damaged and once I replaced it I never had a problem from it. I mainly use them for storing and backing up family pics. The safari browser still connects to some sites, but I found that tenfourfox works far better. I always loved the style, build quality and craftsmanship of the G5 and the Mac Pro.

Makes me wanna get my PowerMac's running.. I got a G5 PCIe and another G5, at least one is a dual.. One of them takes a weird big-ass 20amp IEC cable that I don't have..the other one just takes a normal cable.. Also have the big-ass 23" (that looks like a 27" or something) original apple display for it as well as 2 cinema displays (one dead, one working)..

Just picked up one of these yesterday, thankfully didn't get the same experience 😅 Great video for background info anyhow, thanks

0:00-0:06 and 7:09-7:14 LOL 😂!

Don't give up. There is plenty of information on how to fix LCS. Disassemble LCS and check if your processors boards still have caps around CPUs. Maybe there is a chance to clean everything up. There should be a fuse inside a power supply. MIght be worth a try. Another fun project.

Who’s here after the computer clan video where he try’s to fix it

8:49 and 8:53 if you look closely you can see the white light blink twice every relay click

Love how the coolant system was made a day after I was born

8:46 is the part you're looking for

smelling smoke? tats a capacitor ken

30” Cinema Displays did retail for $3300 in 2004. With Inflation, that is the equivalent price of about $4500 in 2019.

Should have gotten an old 30” Cinema Display to complete it

That intro never gets old.

"predicted: 1/10" that did not age very well

You can see the shielding at 4.05. It looks like it came that way.

I guess the clicking was the short protection, and the bam was the arc or sth. But then there probably was another short behind the protection. Maybe???

You know I know exactly what it’s like to blow up a PSU

it sounded like a nuke was going off

2:45 "dell XPS 630: am I a joke to you?"
