GTX 570 SLI PSU req

Hi Guys,

I'm thinking of getting an additional GTX 570 for my system. My current specs are:

Intel i7 950
12GB ddr3 (6x2GB)
MSI Nvidia GTX 570
2x1TB WD Caviar Blue
Gigabyte GA-X58-USB3
Thermaltake TR2 RX 750w PSU

Will my PSU be able to handle the dual cards? I have not overclocked anything and don't really plan to.

Thanks.

  1. Hello,

    You'll have absolutly no problem whatsoever. The GTX 570 pulls a max of 219 watts. Let's say 240w, just to be safe. Your CPU will pull 130w. If you add everything up, it makes a total of 630w (if you count 150w for the CPU). Add to that your other devices, like fans, HDDs, optical drives...it won't pull a lot. You'll be more than find.

    Have fun,

    I would suggest you read a review about your power supply unit by Hardware Secrets, then you can decide for yourself:

    According to our methodology, Thermaltake TR2 RX 750 W cannot deliver its labeled wattage. It burned after one minute delivering 750 W at a room temperature a little bit above 45º C. Thinking that we may have got a defective unit, we asked Thermaltake for another sample, which burned exactly the same way. In both units the component that burned was one of the +12 V rectifiers.

    Measured maximum power: 583.9 W
  3. Stick with Corsair, Seasonic, PC Power and Cooling , XFX or Antec. 750w to 850w will be great for your system and give you some headroom.
