GTX on a 480w PSU - possible?

[Diggsy]

Okay, asked a few days ago and got no real replies, but I think the thread title didn't help, then I got put off as the price went back up.

But, now that it's down again I am about to hit the buy now button. Before I do, I want to be sure my PSU is up to the task.

So, I have a Tagan TG480-U01. Will it run the GTX, or am I asking for trouble? Anyone running a GTX with a similar PSU?

If it's too much, then I have another question - stick with my current GTS, or dump it on the 'bay and get a new G92 version?

Decisions, decisions...

well in terms of wattage, 480 should be fine, you may want to double check the amps available on the 12volt rails before you try it, although i assume it will all be fine

480w should be ok, but it is if the rails can supply enough amps to the gtx that will determin if it will run.

Yeah, that's my only worry, the 12v rail supplies 28a and I just don't know if that will be enough. It might well be, but I would hate to change card only to find the PSU would need changed too, which would IMO make the upgrade a waste of money at this time.

My GTX ran fine on my AKASA 500W which had 24a total.

Hmmm, sounds promising, what was the rest of your system?

The GTX doesn't use that much more than your current GTS anyway, power wise.

Thanks for that, sounds like I should be okay then. Hmmm, now to try to keep control of my left-click

I have that Tagan PSU running this lot totally fine:

E2140 @3ghz
GTX oc2
4gb ram
P35 mobo
4 x sata HD's
2 x dvd drives
sound card
tv card
wifi card

Thanks guys, raises my hopes a little. It has been a great PSU and I would hate to replace it just yet unless I absolutely have to.
