I'm in the process of setting up a new system. I expect parts to recieve this week.

I have a eVGA 7900GTO 512GDDR3 PCIe16 coming in.
Issue is I read that this card requires 450wPSU with +12v 22amp

My PSU is Antec True Power 450 Watt ATX12V v2.0 PSU
OUTPUT
..............+3.3V .+5V .+12V1 +12V2 +5V SB -12V
Max. Load 32.0A* 30A* 15A* 17A 2.0A 0.3A
Min. Load 0.5A 0.5A 0.4A 0.4A 0A 0A
Load Reg. ±5% ±5% ±5% 5% ±5% ±5%
Ripple V(p-p) 50mV 50mV 120mV 120mV 50mV 120mV

* +5V, +12V1, 12V2 and +3.3V maximum output: 410 Watts max
* +5V and +3.3V combined output: 150Watts


System specs in my sig

So in short will this work or do I buy a new PSU ??

I'd suggest getting something a bit more robust. Silverstone ST50EF-PLUS or the Enhance it's based off of, the ENP-5150GH. 80% efficient, active PFC and while not the loveliest PSU out there solid as a rock.

The reason I'm pointing you away from the Antec is there's been issues with the caps used in them lately and you're better off steering clear of potential problems.

Will it work, probably, however it is not recommended.

Depending on budget & future plans any of the following might be a good choice.

$49: XCilo GoodPower 500W

$85: OCZ GXS 600W

$105: Corsair 520W

$159: PC P&C 610W

This unit, built by Enhance will have some sleeving and more 4pin Molex connectors than the ENP-5150GH. 36A of 12V combined ain't too shabby either.

It will work, and I do recommend it. The Enhance that is. The Antec should too, but there's the cap issue... ;)

The Xclio doesn't feature SLI capability that's native to the unit. You have to use an adaptor for the second PCI-e connector and since there's only 5 molexes to begin with that shunts you down to 3.

The Enhance is between the cost of the Xclio and the OCZ and doesn't have the nasty little problem of excessive ripple under high loads. It might not be as pretty as the OCZ but for someone needing a good solid PSU that can do SLI in the future it's tough to beat in it's price range.
