I have recently decided on which mobo + CPU combo I want for an entry-level gaming PC build: the 970A-G46 plus the AMD FX-6300 (not bulldozer for all idiots who think AMD's latest architecture is stupid zambezi/dozer). I will be OC'ing the CPU. Using a PSU calculator (on extreme.outervision.com), I determined that, just to be safe, running at 4800 MHz @ 1.41 vCore will use about 153 watts.
I know that this board and other cheap MSI mobos are notorious for VRM/MOSFET failures because of the 4 + 1 - phase design. The G46 has heatsinks on the VRM's, though, so that's less of a problem.
But I think 150 watts max. thermal design pow is a tad too much for this cheap board. The CPU pow connector may have 8 pins, but I still think 150W is going to cause VRM overheating and failure. I am especially using a hyper 212 evo CPU cooler, which doesn't blow much air over the VRM's. Also, I want the VRM's to be stable in that environment for 12-24 hours at a time ( I'm saying I don't want it to last as long as a 8 GHz FX with liquid helium in an OC comp).
I was also thinking of the Asus M5A97 2.0, which looks and is far more reliable, with 4 + 2 phase MOSFETs and a large VRM heatsink. But that's $20 more.
So will the 970A-G46 be able to handle 153 watts stabily, with little cooling? Or should I get the Asus alternative? If I duct-tape a 40-70 mm fan to blow right over the VRM's, is that enough for the MSI G46?
Edit: The board is 125w - rated and the FX-6300 has a TDP of 95w. The ASUS board is140w - rated.
