Ummm I hope this PSU can cope . . .

Now I know my PSU is not the best, far from it.
Ok I'll admit when I bought it I though it was a good buy because I got the models mixed up, the thermaltake ToughPower is actually quite good and I got it mixed up with the TR2 which is not as good.
Although I did err on the side of caution and go for the 470w not the 420w

Now on my current pc (details in My system ) it can handel it fine, however I've been looking at a new graphics card for a while to replace my 6800LE 128mb AGP and when I spotted scan had this 256MB XFX 7900GS XXX, PCI-E on today only special offer of £88

While I have been looking at a 8800gts, the best I've found so far is from Novatech (own brand at £175 & lifetime warranty) I was very tempted, but I just cannot strech my budget to that atm

I need some shiney new graphics NOW DAMN IT! I'm sick of haveing to play in 1024x768.
and a 7900GS like that can cope with 1280x1024 with high settings which is my tft's max.

And so I got magpie syndorme and ordered it I'm a little suspious of that HS&F as there's no sinks on the ram, so I added some memory heat sinks to my order

But now I'm wondering if my PSU can handel it, it should in theory . . . but in reality?
Couldn't see any info on xfx's website about the +12v ampage for this card.

The thermaltake TR2 470w is rated as 2 +12v rails 14a and 15a max.
Currently in the BIOS the +12v is reported as a steady 12.064V
Although speedfan is reporting 11.37 - 11.34v, however speedfan does not support the ASRock 4coredual vsta motherboard so I'm not 100% worried about this number.

What do people think?

apart from getting a new psu, which my bank ballance will not be able to take for another month or two at least

EDIT: Typical both the thermaltake forums and the xfx web site are currently down

I've run a 7900GT on a Seasonic 430W for over a year now - the 7900 cards are relatively low power.

I'm running my 7600GT on a 460W Akasa PSU. It's been perfect for the past 2 years - a 7900 can't take much more power.

You can run a 8800GTX on a 520W PSU, so 420 will be fine for a 7900

its sort of a myth that u need a 600+ psu you dont need that amount of power even for rigs with a lot of devices

As you say...TT's are a poor build quality (ToughPowers are an improvement though but still wouldnt want one).

It will be enough to power that rig so don't worry.
The problem with TT's is that when they give up the ghost they tend to take some of your major components with them to the electronics graveyard. Just be aware of this.

Fyi...the TT's sell well on the auction websites as they are bling units so all the 'ill-informed' start bidding on them. Try this then go for something else.

I saw an Ultra X-Connect 500W <<<----- One of the worse PSUs in the last 5 years but also one of the best looking, go for &#163;68 the other day.
