[H]ard|OCP was a little leery about the reappearance of Cooler Master's Game Xtreme series PSU after the first generations poor performance and even more so when they read the labelling on the new 650W model.  While it claims that its single 12V rail will power "the most demanding SLI/CF configurations", the 624W @ 52A maximum power rating is not up to handling multiple Titans nor does it help that there are only two 6+2 PCIe power connectors.  However it is not the PR that matters but how well it can compete against other PSUs with similar power ratings.  Once [H] hooked it up in their torture chamber it became clear that this PSU was not up to the job, about the only good thing they could spot was that it failed less tests than the first generation which does not count as a hearty recommendation.

"Cooler Master is a name synonymous with enthusiast computer desktop builds. You have likely purchased one if not more of its products in the past if you build your own boxes. The GXII line popped up on our radar recently, as we were seeing it on many brick and mortar computer store shelves, so we bought one to see what it is made of."
