how large of a psu do i really need for my comp
My build is a fx 8350, 16gbs(on four different sticks) of ram, GeForce 760 ssd and 7200 rpm hdd with 5 fans. the five fans come with the case. Thank you for the help. If I overclocked the CPU and GPU would that change any thing, would 620w PSU be efficient
For a system using a single NVIDIA Reference Design GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors. Some of the non-Reference Design GeForce GTX 760 cards have a single 8-pin (e.g. ASUS GTX 760 DirectCU II OC) or two 8-pin (e.g. MSI GTX 760 HAWK) or one 6-pin and one 8-pin (e.g. Gigabyte GTX 760 WindForce OC, EVGA GTX 760 SC w/ACX Cooler, MSI GTX 760 TwinFrozr Gaming) PCI Express supplementary power connectors.
If you have or are planning on getting an MSI GTX 760 HAWK the XFX Pro Series Core Edition 550W won't have the two 8-pin PCI Express supplementary power connectors that will be needed. You would have to move up to the 650W model or get a PSU from a different brand like a Seasonic M12 II Bronze Evo Edition 520W (SS-520GM2).
