Hi All


Just got a asrock H81 ProBTC Mobo and have 2 R9 270X with 1350 watt PSU running ok, the mobo has 1 x16 and 5 x1, ive tried adding a 3rd 270X and the existing 2 work ok but the fans wont spin on the 2rd one, any ideas?


I know the 2rd 270X works as it came out of a working rig and Ive put it back in this other rig and it works fine, just wont work in the new rig, the Pro BTC is supposed to run 6 GPUs potentially (not that I'll be doing that), 3 would be nice.

any help would be much apreciated.
