PSU for my rig

[lalondsm]

Hello,

Just upgraded a bunch of components in my gaming rig, and debating using existing PSU or if I should upgrade:

NB I have not assembled this stuff yet.

Components:
Asus Sabertooth Z77 Mobo
Intel i5-3750K
Cooler Master TPC-812 Air cooler
4X4GB Gskill Ripjaws PC1600 DDR3
3 Sata HDD
Nvidia GTX 660 Vid card
Cooler master CM690 II Advanced case
Windows 7 Ultimate SP1

Exisiting PSU
Right now, I have a Cooler Master 750W GX PSU.

I live in Korea and getting a replacement might not be easy or cheap. I did find this and the reviews on it seem quite good.

Any advice appreciated. If additional info required, just let me know.

Thanks,

Simon

A 750w PSU should be enough for a single GTX660 and the rest of the components you use

Your current PSU is more than enough.

While that PSU isn't exactly a good unit, it's more than capable enough for that system.
You're probably using around 250w at full load.

You're fine on that unit, don't worry about it!
