I have a custom pc and was looking at upgrading it since i accidentally bought the wrong power supply. It wasn't modular and i am now looking for a modular one to save space.
I just wanted to know if the wattage had to be 900 or above?

these are the specs:
ASRock Z77-EXTREME4 Motherboard
LG CH12LS28 Blu-Ray Combo Drive
G.Skill Trident X F3-2133C9D-16GTX 16GB (2x8GB) DDR3
XSPC 120mm Xinruilian Fan 1650RPM
Antec High Current Gamer 900W Power Supply HCG-900
Intel Core i7 3770K
Gigabyte GeForce GTX 650 OC 2GB
Deepcool Frostwin CPU Cooler
Windows 8.1 RT
 
For a system with a single gtx 650, a 400W psu should be sufficient, as long as it provides 20 amps on the +12V rails (ref http://forum-en.msi.com/faq/article/power-requirements-for-graphics-cards). I'm not sure if that takes overclocking into consideration.
