PSU wattage help?

[lukeg310]

Hi Guys,

I am building a budget gaming rig. I am not sure what kind of PSU I should get, id like to SLI down the road. I was thinking of going 750Watts but I am finding varied answers, some are saying thats fine while others are saying go to 1200watts. Any suggestions?

What do you guys think of this PSU?

A good quality 750W PSU with 4 x PCIe 6/8 pin connectors is fine for those 2 cards. But I would recommend staying away from Raidmax. Look into Corsair, Seasonic, Antec, etc. Here is a "quality" list: http://www.eggxpert.com/forums/thread/323050.aspx

The GTX 770 is a 230W card maxed out. That's 19.2 amps per card on the +12V rail. The i5-4670 is a 84W (7 amp @ +12V). Together they would draw 45.4 amps. The MB can draw from 10W to 50W. The drives, etc are miniscule. So look for a 750W or bigger PSU with at least a 60 Amp combined +12V rail(s) for some headroom.

You will need 850w.

Here's one made by Seasonic.
