550W for overclocking?

[LuTz]

This is my spec :

i5 3570k
Asrock z77 Extreme3
Corsair Vengance 8GB CML8GX3M2A1600C9
MSI GTX 660 TF/OC
1TB Caviar Blue
Case Elite 431

My PSU is just 550w Corsair, i want buy the 650W but they're out of stock.

From what i read, 550w is almost sufficient for that spec, but what i want to know is 550w PSU capable for overclocking?

VGA and Processor, only a little .. Like Processor @ 4.0 - 4.2Ghz

And just increase the VGA Core speed by a little amount



P.S Sry english is not my native language

Yeah, you don't even need to overvolt the I5 to get 4ghz (i've seen some at 4.2-4.3 with stock vcore) so no difference on the wattage VS stock I5 and overclocking an NVIDIA card with GPU boost doesn't require Vcore so you'll not add load on the PSU...

550w is enough for a single video card setup, you don't need more, Corsair make great PSU so you'll never have any trouble...

OK so it sufficient for my spec

how about to add some fan and some neon?

Hi - Yes you can add fans,neon,etc. You have plenty of headroom
with that PSU for your system.
