So what about Corsair AX860W, ATX Power Supply, 80 PLUS Platinum C..???
For a
system using a
single GeForce GTX 295 graphics card NVIDIA specifies a minimum of a 680 Watt or greater
system power supply that has
a maximum combined +12 Volt continuous current rating of 46 Amps or greater and that has at least
one 6-pin and one 8-pin PCI Express supplementary power connectors.
For a
system using
two GeForce GTX 760 graphics cards
in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater
system power supply that has
a maximum combined +12 Volt continuous current rating of 50 Amps or greater and that has at least
four 6-pin PCI Express supplementary power connectors.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.
Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
The
Corsair AX860 (SKU# 75-001305 / CP-9020044) power supply unit, with its
maximum combined +12 Volt continuous current rating of 71 Amps and with
six (6+2)-pin PCI Express supplementary power connectors, is
more than sufficient to power your system configuration
with a single GeForce GTX 275 graphics card. It is also
more than sufficient to power your system configuration
with two GeForce GTX 760 graphics cards in 2-way SLI mode.
In terms of electrical quality it is Tier 1 since the Corsair AX860 uses Seasonic as the OEM.
