GTX 560 2GB x2, which PSU?

[steveg333]

What kind of PSU do I need to run two of these?

GPU:
Galaxy 56NPH6HS4IXX GeForce GTX 560 (Fermi) 2GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card


They don't give the voltage but they say that a minimum of 450w is required. I'll provide missing info if needed.

For a system using two GeForce GTX 560 Ti graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater power supply that has a combined +12 Volt continuous current rating of 43 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

If you want your system to be able to run Furmark or OCCT GPU 3D stability testing then increase the combined +12 Volt continuous current rating to at least 53 Amps or greater.
