3 x Gigabyte R9 270 Power Supply

[dragontech1]

Hi, will a 750w Corsair PSU be enough to handle 3 x R9 Gigabyte 270 graphics cards?

Thanks for your help!

Yes, that'll work just fine 2 270's in Crossfire only require a 500w power supply so 750w is enough for three.

One thing though...I don't think you can run three 270s in Crossfire. I think the max is two because the cards only have one interconnect a piece on them,. Unless you're mining in which case forget what I just said.

Hi, thanks for your response! I plan on mining with all three, I originally planned on 2 x 280x cards but the price and supply is ridiculous at the moment!

The 270 can be overclocked very easily to a 270X and at that point its mining performance is greater than a GTX 780 ( 452khash/sec for the 270X vs. 450khash/sec for the 780) so they are great mining cards! I use my two 270X's in Crossfire to litecoin mine and I get great performance with them.
