Hard to say. The PSU should be powerful enough, on paper. However, it's not honestly labeled. For example a Corsair 450VX is supposed to be weaker, with only 450W instead of 500W, but in fact it's more powerful (33A). CoolerMaster doesn't disclose the combined amperage, so I'd assume it's a lot less than 16+16 and they prefer not so say how much less.
If you remove the card and use integrated video, does everything work? If you put the card in another PC, does it work? Just curious if it's the video card that died or the PSU or both.
