Power draw on graphics cards

killianzz · 4 Mar 2011 at 23:54

I am currently deciding on what graphics card I should buy. It is currently between a 560 twin frozr, 570 twin frozr or a 6950 (twin frozr doesn't unlock). If the 6950 is cheap, quiet and has a good % of successful unlocks then that would be ideal. Noise is important though.

My PSU is a corsair TX750. Processor is 2500k to be clocked to 4.8ghz under a Noctua D-14. As I plan to to SLI in the near future, would this PSU rule out the nvidias? Considering that I would overclock them. I know the 6950s wouldn't be an issue, but the gtx's have a bigger power draw, especially when overclocked. I suspect 570's could be a problem. Also, would the 1gb of ram on the 560 matter too much?

Thanks, Rich.

Should I move this to the graphics card section? Probably a good idea.

Amazing what you find if you google it

..

GeForce GTX 570 in 2-way SLI

* A second card requires you to add another ~225 Watts. You need a 750+ Watt power supply unit if you use it in a high-end system (800+ to a KiloWatt is recommended if you plan on any overclocking).

I have to ask, what are you planning on doing with all that GPU power? 2560x? 3D? Or is the extra few hundred pounds over par purely for maxing out Metro 2033?

Thanks. I was using wattage calculators, but they were giving me amazingly diverse answers +/- 200. The reason for all the graphical power is that I am going back to university next year, and I know that I wont be able to afford another computer for 3 years. I want to be able to play games at high detail for that period, so im shelling out now. I would probably get a GTX 580 if I had the money for it now, but I dont. SLI is a way for me to spread the cost slightly.

Oh ye and maybe 3d after a price drop

Sounds about right. Definitely wouldn't be able to overclock the cards in SLI, but I should be able to still have a hefty OC on my 2500k. I think the fact that I wouldn't be able to overclock them would make me more inclined to go for a 560 twin frozr SLI or a 6970
