What PSU Wattage should I use (Specs included)

JuanBar · Oct 4, 2014

I am building a new PC and kind of going overkill, my question is what wattage do I need?

Specs:
ASUS MAXIMUS VII HERO LGA 1150
EVGA SuperClocked GeForce GTX 760 2GB 256-bit GDDR5 (Two of these, overclocking)
Intel Core i7-4790K Haswell Quad-Core 4.0GHz (Overclocking)
HyperX Fury Black Series 8GB (Three of these)
Kingston SSDNow V300 Series (240G One of these)
Seagate Hybrid Drive ST4000DX001 4TB (One of these may add more)
ASUS DVD-Writer
Rosewill RNX-N900PCE
Enermax Liqtech 240 All-in-One Liquid Cooler 27MM

Thanks in advance

get a gtx 980 with 2x4 gb of ram in pair dont use 3 separate 8 gb sticks if you want more ram then buy 2x8 gb .

if you do a SLI with gtx 760 then you will need a 750 watt PSU and for gtx 980 you will need a good 550 watt of PSU overclocking included.

Ok thanks for your input, I would rather keep the three sticks of ram or two 8 sticks and two 4 sticks to fill all the slots

But thank you I had my PSU way over what I actually needed

okk good luck just always buy ram in pair or else there is always a 50-50 chance of ram not working together.

I am it is all the same ram, also one more thing if I went with custom liquid cooling would that add much powser consuption?

Per Nvidia, the recommended MINIMUM power for a system with two GTX760's is 700watts with a combined +12 Volt continuous current rating of 50 amps or greater and at least 4 6-pin PCI-Express connectors.
The EVGA card you listed regures 1 x 6-pin and 1 x8 pin power connector, so you would need at least 2 X 6Pin PCI-E power leads, and 2 X 6+2 pin (8pin) power leads.
So, my recommendation is for a 750 watt PSU; This is one of the best out there.

No not really.

JuanBar :

A little bit, but a quality 750Watt unit such as I listed should handle it. Here're a couple more links for information:
