Wow! I've been getting every single one of those issues! (you can only imagine my frustration) I'm taking it to a repair and see what they can do ASAP, thanks for the video, I was lost and unsure about what to do but this video was exactly what I needed! I'm 100% subscribing!

Good information for end users. The first about 8 minutes he says be sure to plug it in and turn it on. The rest of the time, he's telling you to use a tester. They aren't perfect but you will get a basic idea of output from them. I was hoping to learn something about how many milliseconds a given power supply can stay on if the power is dropped. For example, would 30 milliseconds cause a failure.

mine was failing for nearly a year, every now and again it would crash, fans would spin but wouldnt boot up. never suspected the psu was the problem (because the fans would spin, i would expect no power at all, plus it worked fine a lot of the time)

My Pc just turns off suddenly and then restarts again. And it's as frequent 1-5 minutes interval between each random shut down.

Hi, I just bought an Aorus 850w PSU. I tested it out of the box no load. My issue is that power good signal is 70ms & 80ms. What does this mean? Should I send it back as faulty??

ive recently encountered that when i try to turn on my work station, my power supply fan does one rotation like its trying to start, but stops. could this be anything else other than a bad psu?

Hey my power supply’s fan has stopped spinning entirely. Has the on off switch on the back. It’s on, but never spins anymore.

Is it possible for a hard drive to fry the Sata/peripheral port on a PSU? I’ve been trying to trouble shoot a computer that wouldn’t send power to the HDD. So I plugged the HDD to another computer that works fine but after plugging in the HDD, now the original SSD doesn’t show in windows or even BIOS

Can a pc draw power when i switch my psu off? My pc flashed a blue light when my psu was switched off is that normal? Or is my psu damaged? Oh my monitor power cord was connected to a power source idk if thats related to it.

I have a 2 year old PSU from Corsair. It takes around 7--10 sec to shut off. After I have shut the computer down and the screen is black. Could that be an issue?

My computer dies every 2 mins while gaming. I checked and my powesupply fan emits a burning smell but when I checked, my graphics card’s fan is not working. I checked and its temp was 85-88 degrees while not doing anything/gaming. Im confused if the powersupply is the problem or my gpu

Every time I tapped the power supply the screens would turn off (pc would stay on) and mess up my graphics drivers and I would have to reinstall them. Does anyone know why every time I tapped it that would happen? I would really appreciate the help :)

my psu pulses at times but does not turn on. MB, GPU, fan lights pulse once but that's it. If i leave it for a while or switch off the PSU at the back and leave for a while it starts up perfectly fine. PSU is only 1.5yrs old. Once or twice it shut down during gameplay. Once i had BSOD (running after windows update - not sure if that was the culprit.) I've removed 2 RAMS after the first few time it happened, ran fine for a while then started with the pulsing again. any advice please?

Charles here an active members of ITProTV currently watching the MS-900 Series. When I was 13 I was getting into computers, never had the internet and my computer one day wouldnt power up. I ripped my Windows 98 machine apart trying to find out what was wrong (i had no idea what I was doing) turned out it was the fuse in the plug that had blown...my Mum wasnt happy with me.

My 600W PSU just died today.. it started off earlier this week when I was playing the game … out of no where my fans went 100% and the monitor display turned off. Then it happened again when I did a little bang on the desk. I ended up smelling the burning smell when I tried to fix my LED lights in the front of my case, I plugged it in & I heard a pop, it had shut off. I unplugged the led lights & turned the PC on, it was a delay and when it came on i smelled a burning smell so I instantly shut off the power switch then unplugged the cable. I smelled around my PC just to make sure it wasn’t the MB because that was my first thought. I confirmed by unplugging the cord & going to another socket & trying to turn my PC on and it was a few seconds late coming on, it came on then shut off came on again & that’s when i decided it was my PSU. Lucky it didn’t take out my 2070S & i7 9700k along with the ram

My pc stopped working due to a power outage and it won’t turn on but every 30 seconds my fans spin and the lights turn on for like 1 second do you think my psu has to do with this
