What size of power supply do I need???

[FX7026]

I am building a new computer and am not sure what size of power supply I am going to need so hopefully you can help me out.

Here are the components that I will be ordering:

Motherboard: ASUS SABERTOOTH 990FX R2.0 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS

CPU: AMD FX-8350 Vishera 4.0GHz (4.2GHz Turbo) Socket AM3+ 125W Eight-Core Desktop Processor FD8350FRHKBOX

Video Cards: 2X EVGA SuperClocked 02G-P4-2765-KR GeForce GTX 760 2GB 256-bit GDDR5 PCI Express 3.0 SLI Support w/ EVGA ACX Cooler

Memory: (2X for a total of 16GB) G.SKILL Sniper Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-14900CL9D-8GBSR

Not sure how much hard drives and CD drives affect what size of power supply you need so if you want me to post those details let me know.

I think a 750 watt PSU should do the job. Look for corsair, seasonic, or xfx brands

To point you in the general right direction try doing this!!!

CPU TDP + 2 X GPU TDP + 40 WATTS FOR OTHER BITS = Answer!!

So you add up all the Wattage of your major parts + 40 Watts will give you a ballpark number. Then you take that number and divide that by 12 volts and that will give you your AMPS!! That you will be pulling from your PSU OK!

That and don't be cheap on what you see, get one of the recommended ones like he mentioned, I like my old Antec myself but won't fit most cases.

Don't be cheap on your PSU, it's what runs the thing
