Can I power it?

Very recently bought a second hand 770 to SLI with my current one and it should be delivered sometime next week.

Then it hit me. I've only got a 650W psu and now I'm uncertain if I can run dual gpu's given that stock 770's take 230W each.

The rest of my rig is in my sig and my very quick calculations show I might by pushing it.

GPU+GPU+CPU+HD+FANS=600
230+ 230+ 80+ 10+ 50 =600

What is the make and model?

Antec earthwatts 80+ Platinum

No skimping on the psu

That would be fine...

...but it only seems to have two PCI-E connectors.

It does? I'll physically check it later

I can always swap it for a 700w cooler master which has 4 PCI-E but is less efficient

That'd work.

Need a lot more posts to get into the MM so I can sell my stuff!

Got components lying around everywhere

I must say, that psu is extremely overpriced for a non-modular 650w unit that can only power a single dual plug gpu. Don't get me wrong, from the reviews it seems to be a good unit, just seems really overpriced to me.

Which model is the Coolermaster? They have released some shockingly bad psu's in the past.
