My New Power Supplies

[zabuscus]

I am planning on upgrading my computer totally. I am getting an Intel Core i7-2700K Sandy Bridge 3.5GHz (3.9GHz Turbo) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623i72700K, CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9B, and an EVGA 025-P3-1579-AR GeForce GTX 570 (Fermi) HD 2560MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card. I am just wondering what power supply I should get for these new upgrades. I would be very happy if someone could recommend me one. Thanks!

For a system using a single GeForce GTX 570 graphics card NVIDIA specifies a minimum of a 550 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

The XFX ProSeries 550W Core Edition (P1-550S-XXB9), with its combined +12 Volt continuous current rating of 44 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is sufficient to power your intended system configuration with a single GeForce GTX 570.
