120v at 15amps is 1800 watts
12v at 100amps is only 1200 watts
120v at 10amps is 1200 watts..


at 100 amps, the wires might start to twitch when you turn it on...

great stuff!
I've converted a used 500w CP-Power-Supply (very cheap at ebay, sufficient for me), wich works fine. There's no need to spend so much money for a overpriced power supply. just go for used "brand"-stuff and you'll be ok, I wouldn't trust the no-name.

Just bought 2 of these guys! Gonna wire them in parallel for 800 watts, Power all my chargers or My Amp and subs in my dorm room....:lol:

Couldnt pass up a dollar a peice! was 17 dollars for 2, shipped. Get em while there hot

OMG .. Only in America ... :lol:

W00t!:party::party:

Good find man :yes:... just be careful when wiring them in parallel... keep the cases separated and hands off during operation...


Alien

Will do Alien, Progress pics. Got them Wired up, and all the startup wiring done so the thing actually arms...
Great guide for the HP #194989 and HP #280127 can be found here:

Have yet to put a load on it, or plug it in yet, need connectors to go to my load of choice (700watt amp and dual 8in subs) :lol:

Nice!!!

Good info
 

Nice thread. Good info. It looks like some comapnies are doing some server upgrades, and a few employees are cashing in on the out dated power supplies?? I know allot of businesses could care less where the old equipment goes when these upgrades are in progress. It's just too much work for them to advertise, sell, and ship old equipment, so they just junk them and move on. Nice home resolution though. I have a friend who does this kind of work for a living so I will have to ask him to hook me up with a few of these for my own power supply needs. He maintains a couple of very large server facilities for a security company, which handles the majority of American banks account transactions across the USA, so I am sure that he can come up with a few PSU's for me. Using the info on here I should be able to setup a sizable PSU for my R/C needs.

Lesons learned today,
-Heatsinks contain floating high voltage
-My power supply sounds like an idling 747....
-My subs run just fine on 1 400watt unit.
-80hz shakes my room, my house, and my neighbors house
-80hz blasting aggrovates my parents in about a minute.

:) now i have a spare 400watt unit

lol, I use to have 4 10" subs in a gigantic box in my room. That sucker went below 10hz. Went on every morning as a alarm. Imagine 600W rms going off at 9am. I use to run car amps. I've have a few other Server PSU and plan to setup a system in my garage with the spare car audio that I have left over.

my high school setup.

A good reason for them not to touch when they are on... you can get a big spark between them... you can even short the internals... did you remove the ground to get them running together?

It was unplugged, just had not discharged yet,

Amp was running fine on just 1 PSU tho

Yep... those Caps will hold a bit for a while...
