i5 3570k OC to 4.4

ASRock P67 EXTREME4 GEN3

crossair vengence 16gb

HD 7970

segate hdd 2TB 7200rpm

SSD 128 gig

2x samsung DVD RW drive

3 cabinet fans

Noctua NH-D14 120mm & 140mm SSO CPU Cooler

I m thinking of 600w PSU with one 7970 and maybe 750w with two 7970's xfire.

As I live in Hawaii and we have the highest utilities in the country, I want to have enough power but just enough. Also should I go go gold or even platinum rated. Running about 12hrs a day on most days.

Strictly gaming and surfing web as I'm sure you guessed.

Corsair HX750 will be fine. Plenty of power, good warranty and pretty efficient. That's what I use. You could get away with 650 if you want but it is good to have some headroom especially since you are considering Xfire.

Have you bought these parts? I question why you got a p67 board with an Ivy Bridge.

@topic - 600w would be plenty for a single card. For 2-way CF though, 750w would be really close to the edge, and seeing as you're also overclocking, that leaves little to no headroom left. The PSU will be working very hard.

I suggest an 850w. Also, any 80 plus certification would be good, Bronze,Silver,etc, the difference isn't really that big.

Like excella says a P67 is an odd choice for that CPU, z77 makes more sense (in which case the ASrock extreme 4 has VRM issues)

For a PSU even if overvolted when OC'd that setup isnt going to pull more than 450W at load, for peak efficiency you want the PSU to operate in the middle 3rd of its range so 600 or 650W would be more than enough and efficient for that build using a single card

No I have not bought the board yet so I will look at z77 for sure. Thanks for all the good info guys. One last question with an OC and 2 card setup what should I be looking at? 850+. I really only want to upgrade my psu once and I am for sure going xfire in next 6 months. Still havent decided on gpu either. Any 2cents is appreciated there.

So things have changed for me financially and I will not be doing the upgrades I was hoping for some time. I will be upgrading to a single hd 7970. With that in mind can you guys reco a good 600w-650w psu that will power (1) 7970 and OC IB i5 3570k

I can't access that link, but I have heard good things about Rosewill from others. Just google a few reviews and then make your decision from there.

Rosewill is a house label of Newegg, so they most likely have an idea on what people want. Their PSUs are made by ATNG, which is a very reliable manufacturer.

Anyway, good luck with your build!

7970 is a great card. It outperforms the 670 on most games, save Nvidia-optimized ones.

Do you have any questions in particular?

Does OC well? and when do you think AMD will drop their pants on price again? SOE usually goes nividia or so i have heard
