Looking for 700W+ Replacement ATX PSU with high 5v/3.3v rating

post #1 of 7
Thread Starter 
I've got an old system at work that has a failing PSU and I need a replacement. The system has a lot of PCI (not PCI-E) cards in it that use 5V and 3.3V currents so finding a PSU with enough power at those ratings has been troublesome. Current specs of the PSU are:

700W
12V: 36a
5v: 45a
3.3v: 50a

I've dug up the specs of the components and the PC needs most of that power so I'm not willing to deviate on the minimum output. It's an ATX PSU in shape but I am willing to deviate from that to make this work. 2u/3u or whatever even if I have to mount the PSU externally to its existing case.

Are there any sites that allow searches by each 5v/3.3 rail? Searching for 700W or greater just gets me new PSUs with a high current rating on the 12V rail.

Any help/suggestions would be appreciated.

I'd like to recommend EVGA's SuperNova 750W G2 it 5v and 3.3v spec is even lower than yours. Based on what I see most 750-1000W unit these days have their 5/3.3v capped at 24-25A. Newegg.com list these specs for PSUs if you serach for them there, if not listed you can check the screenshots as those are clearly there.

Please read again. I need at minimum! Who wants lower current ratings?

12V: 36a
5v: 45a
3.3v: 50a

Just telling you almost all Consumer PSU nowadays have 3.3/5v rating(24/25A) way below your demand, most of their power is routed through the 12v rail. I also told you where on Newegg to look for those specs. Best of luck rolleyes.gif

I know new power supplies won't work. 4th word of the thread is 'old.' wink.gif

You recommended a PSU that does not fit my requirements and a manual part by part search. I was hoping for a site that has filters like those on the left on Newegg for individual rails. Most sites have nowhere near the filters of Newegg so I don't have much hope in that but I might as well ask.

If that helps you. Prices.

Sure does. Looks like a copy. It mentions Zippy, which is the manufacture of the model I need replaced. Zippy or Emacs

Looks like Radwell has a hefty markup on one.
