R9 280x

Ok I was right, a shame it broke though. For the next psu, try to get one that has only 1 big 12v line. Also for every psu I buy I google the model and review. I look for a good stress test and read how it went, the thing you gotta look for is how it handles a full load for a long period of time. You have to think that you will use the psu 24/7, a cheap one will fail on you.

pd: I'm running 4 280x under a 1200w gold coolermaster and it runs just fine. To run just two cards a good 850w psu will do.

I am planning costs for my rigs, and I am kinda confused about Your post. If 4 cards = 1200W, 2 cards = 600W. Why You said 850W??

2 cards = 600W, .............+ MB + CPU + HDD, etc = 800W

so then 4 cards = 1000W + + MB + CPU + HDD, etc = 1200W
250W per card, so

2cards = 500W + rest 700W

257w each card, a cheap processor uses 65w, a high end one 120-160w, each ram module 10-15, hdd 10, a bit more due to risers resistance. You can use a 1200w for four cards or a 1200w may fall short for 4 cards, it all depends on the rest of the rig.
