[Nerik21]

Hi guys,I'm planning to buy msi gtx 660(non-ti) twin frozr III in SLI but I'm not sure is my psu enough for for SLI? I have Seasonic 620GM 620W and this is my current setup:

HAF 912 Plus
I5 3570k @4.2ghz
Z77A-GD55
2x4GB DDR3 Kingston Hyperx 1600mhz
Corsair H60
Seasonic 620GM
2TB WD Green
500GB WD Blue
Intel 520 180GB

That is probably pushing it a bit. I think you should just put the money toward a more powerful single GPU like a 680. How much will you spend on the 660s? You may need a upgraded PSU also. Any thoughts Blkfx1 and hellokitty[hk] about the PSU?

In my country is much cheaper to buy gtx 660 in SLI than gtx 680,my psu have 12v1 24A and 12v2 24A so total 576w on two rails

You're just about fine I think, according to TS a 660 SLI setup uses 365W under load.

If you run into problems you might want to try dropping the overclock on your CPU.

I oc my cpu 4.2ghz voltage 1.152v,also my psu support one 6pin and 6+2pin

The GTX 660 only needs one 6 pin connector so you PSU is fine in terms of connections.

The MSI TFIII isn't the best cooler though, check out the Asus DCUII or Gigabyte Windforce solutions.

The TF is pretty good, the new dust cleaning feature is garbage though lol.

I can choose gtx 660 in SLI or gtx 770 lightning,but my psu have one 6pin and 6+2 pin and for lightning I need 2x8 pin so I must use 6 to 8 pin adapter,is it safe to use that adapter also I want to oc a little bit?

Dont waste your money on that Lightning garbage. 1) MSI products havent been good from my experience. 2) The TF cooler is gimmicky and cheap. 3) It is overpriced. Get this instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130921. The EVGA 770 I recommended requires a 600W PSU: http://www.evga.com/Products/Product.aspx?pn=02G-P4-2773-KR.
