So im basically stuck on what psu to get. Ill be oc the 8350 a lot and that thing chews through power. And ill also have a 780, i might SLI in the future. So keeping that in mind, which power supply should i get? I was thinking the AX860 from corsair. But im not sure if that will be enough. :T Preferably fully modular :T
860w enough for 8350 and 780 both OC?

Both these guys are correct.
Nvidial recommends the following for a Single GTX 780: Minimum 600Watt psu for entire system power with a minimum of 42Amps on the 12V rail. It is the current - the amperage - that is really important.
The Corsair 860 has 71+ amps on that rail. It will work with SLI as Nvidia spec. 850 Watt or greater with minimum of 65amps.
Should be good to go!
P.S. When happy with the reponses, don't forget to pick a best answer so others know the question was solved. Thanks for posting.

HX 850 has lower ripple, better voltage regulation and is substantially cheaper.
as for the wattage

So 600 + 250 for 2nd card = 850

For a system using two GeForce GTX 780 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 65 Amps or greater and that has at least two 6-pin and two 8-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.
Overclocking the FX 8350 from stock to 5GHz requires at least an extra 9 Amps or more from the +12V rail.
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 sufficient to power your system configuration with two GeForce GTX 780 graphics cards in 2-way SLI mode.

Much appreciated. I ordered it today.TRENDING THREADS
