Hello everyone, as I've seen in plenty of threads most GPU vendors ask for a lot more power than needed in the requirements, so the question is: can an Antec HCG-620m power 2 Gtx 660 ti in Sli?

My specs are:

Intel i7 4770.
1 Asus GTX 660 ti
3 Led fans 140 mm
1 SSD
1 WD 1tb hard drive (green label)
1 Optical disk.
1 CM Hyper 212 Plus Fan
2 x 4 gb 1333 ram.
Asus Z97A Motheboard and the before mentioned Antec HCG-620m PSU.

And I want to buy a 2nd GTX 660 ti to run it in SLI, what do you think, can I do it without blowing up my PSU?

Thats the thing, I know that with better wattage I oculd make it fine, but I don't have to budget to buy the GTX and another PSU.

You would need 4 - 6 pins for the cards , the Antec only has 2.

I would get a better power supply.

It's a SEASONIC but it's not as good as like the XFX versions of a SEASONIC.

4770 on load around 180watts gtx 660 ti on load 150 watts so 150w+150w=300w+180watt=480 watt and then power to rest of the system. i might be able to pull this off but u really come so close that i cant guarntee anything. no O.C for sure

Thanks everyone, I guess I'll wait until I get a better PSU or until I can sell my GPU and buy a better one like the upcoming 800 series from Nvidia.

By the way I chose hiimmikkel's answer as solution because he was the first, and he kept helping me, but like I said thanks everyone for their input.!

I've seen SR-71 Blackbird that you have given in the past very good PSU recomendations, what would you suggest me for an 750 watt PSU, or should I open a new thread?

Seasonic M12 II 750W or XFX Core 750W.
Best possible PSUs.
Only differenence is that the XFX has 2x 6-pin and 2x 6+2-pin connectors,while the Seasnoc has 4x 6+2-pin connectors.( At newegg,the Seasonic is $5 less.)
