The HP DPS-1200 is a $20 1200w power supply, capable of OVER 100 AMPS! But is it really noisy on the HF Bands? Maybe a little, but it's not bad for $20! I compare the noise with a battery, a Radioshack 3A 12V unit, and the HP unit on my Icom IC-7300.
These power supplies are surplus from somewhere, since there's so many on eBay and they're so unbelievably cheap - see for yourself at www.ebay.com/sch/i.html?_from...
I bought mine for $24 shipped, and it was delivered in 3 days. These units are often bought by RC hobbyests to charge lithium/LiPo batteries quickly since they supply so much current.
You will have to do a small resistor mod to get it to turn on, and figure out how to connect some wires to the large PCB trace contacts - I used a drill and some hardware.
Here's the resistor mod instructions: blog.seidel-philipp.de/hp-dps...
