Last year, I build a budget gaming build with a 650W 80+ Bronze power supply. For Black Friday, I'm looking at some upgrades, but I'm not sure if my PSU can handle it. I tried two different power supply calculators. They both say 750W, but the load wattage is 567W. Do I really need 750W, or will mine be good? The specs of what it will be are below:

Standard Desktop Motherboard
CPU: AMD FX-8320 CPU (125W)

GPU: AMD Radeon R9 390 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814127874)

RAM: 4 X 4GB DDR3

Storage: 1 X SATA 5400 RPM; 1 X SATA 7200 RPM

Accessories: DVD/CDRW Combo; PCI WLAN Card; Fan Controller

Cooling:
3 X 120mm Fan
1 X 140mm Fan
3 X 200mm Fan
Corsair Hydro H60 Liquid Cooling Kit

EDIT: Just want to say thank you to the people who have responded so far. I'm still going to wait for more replies, but I think I'll go with an 850W (Future room for expansion, and it's on promotion on newegg for just $5 more than the 750)

I figured all your components plus a couple of USB devices and an overclock on the GPU and CPU, 24/7 use, and came up with 647 watts. I know thats a little pessimistic, but still think you need to leave at least 100 watts of headroom.
