GTX Power Supply

Tiberia · 11 May 2007 at 22:57

What is everyone else using to supply their GTX's? What would be the cheapest power supply to comfortably run a system with a GTX in (safely, so prolly need to be a branded PSU)(also conroe e6320 overclocked to 2.4-3ish, two hdd, 2GB ram and the antec 900's case fans).

I was looking at getting the Tagan TG580-U15 580W ATX2.01 Easycon SLi Compliant Modular Silent PSU £80 although it is currently out of stock and i want to be ordering my system monday so i need alternative ideas. (also whats everyones view on this power supply)

Thanks in advance for all of your replies!!!

corsair 520 will run a single gtx fine

or the Antec TruePower Trio 550W which is cheaper! Not modular though.

Anything around the 500W mark from Antec, Corsair, Akasa, Enermax, FSP will have strong enough rails to take a full system inc. GTX and a moderate overclock

interesting, didnt know whether or not the corsair 520w would run the GTX, would there be any risk of during gamming it falling short ( or doing anything, eg. 3d mark/benchmarking etc). I personnally thought that it might fall short with GTX+Conroe combined system.

The Corsair 520W would be fine, its a rock solid PSU. It can run a lot more.

The combined Wattage of a GTX+ Core2Duo system isn't that much, 300W tops. It's only once you start overclocking that the PSU might hold you back slightly, but saying that the Corsair PSUs are excellent bits of kit - single rail goodness.

What sort of overclock levels are we talking about here, im planning on taking the CPU up to 2.4GHz but one day may end up taking it to 2.8-3GHz

Jokester · 11 May 2007 at 23:52

I'm talking well over 3GHz and an overclock on your GPU as well.

I have just found that my corsair hx520 will not
run a 1950 pro 512mb without issues i get black screens
and random restarts during gaming desktop it is fine
as to whether this is indeed the psu or the card overheating is unclear
but i do suspect it is the psu the card needs 36a although the corsair is 40a
rated that is split accross rails + i did try putting a house fan at side of case directly pointed at the gpu and still had these issues thus i suspect the corsairs are not as great as i first thought i think for any card 36a + a single rail
high (A) psu is required.

The X1950 doesn't need 36amps at all. My 2900XT works fine on a Tagan and that only has a maximum of 35amps in combined mode. The recommended amps is usually around 28ish for that card.
