I neglected to see this specification when ordering this card. I know from past experience, "It'll draw what it wants" So, something like an EVGA 7900 GTO will attempt to draw 22 amps from a power supply with a single +12v of only 10 amps. The result is a smoking PSU, right?<br />
<br />
I guess my point is is that at first I noticed that the X-2 puts out 17 and 18 amps on each +12v rail. At first I didn't notice the second +12v. So I was thinking, "Oh crap! This thing severely underpowers the video card!" But then I noticed it had two of these +12v rails....soo.....<br />
<br />
Will this PSU be able to feed my new 7900 gto's 22 amp on the +12v rail appetite sufficiently? Both 17 and 18 amp +12v rails will together "feed" this video card more than enough, right?<img src="/images/smilies/confused.gif" border="0" alt="" title="Confused" class="inlineimg" />

The 7900GTO will never draw 22A. Off the 12V rail, that would be over 260Watts (22A * 12V = 264w). You need to have at least 22A on your 12v rails for your computer with that video card to work properly. I had a 400W Ultra X-connect, and it had 16A on the 12v rail. I was able to run a 7600GS on it, which asked for 18A. In short, your X2 shouldn't have problems running it, but you may not be able to overclock your 7900GTO much.

Maybe I'm missing something here. Minimum requirements on EVGA's website say that it needs 22amps on +12v. I guess my question was, will both +12v's on this PSU power the card properly? Or is the card only getting one rail at a time?

Some PSUs "merges" the rails. I'd say hold on and get something else than those Ultra PSUs. They're VERY cheap, and is known to explode (Ya RLY!) and catch on fire even when they're shut off.

</div>Damn...I really like the look of it. I'm looking for a modular PSU with removable power cords, and the kind that stay crimped when you bend them, like this Ultra has. Any suggestions?<br />
<br />
EDIT: any reviews I've found on this PSU deem it an excellent choice. I can't go by "Ultra's explode" as a reason to go get another one.<br />
<br />
There's the myth that Crown Victorias explode when hit. Any car can explode when hit from the rear at 90mph+. So....I wanna hear some stories of Ultra PSU's exploding, particularly the X-2.

</div>Ultra has a bad rep for older stuff, much like the much-maligned TigerDirect rebate which used to suck, but is now just fine. I have 2 Ultra PSU's and they work great.

I also have had a Ultra PSU that worked fine. The 22A means that you need that much in a powersupply, the graphic card is not using that alone. Aorry if I was not clear about that. Since your PSU has two rails, each should power something different. It could/should/would hopefully have one rail for the cpu, and the other for the graphics card. You can't add up both rails to get the max between them. My OCZ has 4 18A rails, which if you added them up, would be 72A, but instead the max for the 12V rail is 50A. Your X-2 should be able to run the card, but may not be able to give it enough power to overclock it a lot. The best way is to try. You won't destroy your computer by underloading the componets, the computer just won't boot.

</div>Thanks.<br />
<br />
I was really more worried that the card would attempt to draw more amps than the power supply could handle and smoke and just ruin my day. I think I'll give it a shot...I just really like the force-flex cables. I can't really seem to find any PSU's with those type of cables.
