i5 3570k @4.0Ghz PSU Question

Hey, everyone.

Looking at changing my FX-4130 to a 3570k and I'm looking for a safe OC of 4Ghz. However, my current rig is powered by a Corsair 550w PSU. My question is this: Will the PSU be sufficient for that OC with a GTX 660?

Sorry, but my knowledge of PSU and the overall power required for a build is limited at best. I know the GTX660 requires 430w+ and that's as much as I know, so any information would be greatly appreciated.

Many thanks.

with 2x 660,actually

I could run 3570k @4ghz with SLI 660's on a 550w PSU? Is that what you mean?
Are you sure?

yes ofc.

with a higher end psu you can do this

I'm used to having a silent PSU, my Super Flower Golden King 550W never turned it's fan on other than in really hot and very high power draw situations. Example: I had two 18W pumps, two GTX680's overclocked and Folding and a 3770K at 4.6GHz Folding, four HDD, one SSD, a ton of fans, loads of LEDs ect. Even then the fan wasn't on all the time, it'd turn off after a while and cycle like that. Apart from that it was never on and hasn't been on in months.

while your 550w would work with overclocked 3570k and sli 660's i would recommend a 600-650w.
i find it nice to have more wattage to play around with, just incase especially with overclocked cpus and gpus.

but as it stands atm a 550w will more than suffice, i believe the 3570k will use less power than your fx4130 even while overclocked.

Most 3570k's will do 4.3-4.4Ghz at volts that a hyper 212 can handle, can't they..?
No point selling yourself short and only going for 4.0, push those clocks mate, don't be scared

As to the PSU, you'll be utterly fine
I've seen a mate run a 8120 and a 7950 on a CX430 for two years with no problems... Obviously that's stupid, but I'm just putting it into perspective

You'll be fine

a 4.0ghz overclock on most 3570k chips could do it on stock volts using less than 95w hell i can get 4.2ghz on mine @1.010v stock it sits at 0.985v when it turbos to 3.8ghz it goes to 1.010... i have a 7950 gpu currently overclocked and my cpu is currently overclocked to 4.5ghz and i barly draw 300w from the wall at full load...with 4hdds 1 ssd and a blueray drive also plugged in...

i would say your psu is overkill.... for what you want tbh you would get away with a 450w...

Thanks for all your useful replies. It eases my mind greatly.
