CoolerMaster G650M vs Corsair CX600M for gaming rig

Hey guys,

My psu recently passed on to the next world, so I need a new one. I'm down to two choices:
The CoolerMaster G650M and the Corsair CX600M. Both are the exact same price, both are modular and both have an 80+ bronze certification, but the CoolerMaster has a little bit more power and it has 2 more PCIe connectors that the Corsair.

However:

The Corsair has a reputation of being the most reliable out there. Which one should I get? I might go crossfire at some point (probably two 7970's). Is 600 watts even enough to power two cards?

Thanks in advance,
Cheeki.

  1. No. It is not enough. You need a good 750w PSU to power 2 HD 7970s. I recommend this one -

    XFX Pro series 750w 80+ Bronze certified semi-modular PSU - http://pcpartpicker.com/part/xfx-power-supply-p1750bnlg9

    Thanks for the (very) quick reply, however $107 is way over my budget for now.

    This will do. It's the non-modular version -

  4. Dottorrent's recommendation is good. If you want to crossfire your 7970 in the future, 750W is the lowest you should go and $80 before rebates will generally be about the best price you're going to get on a 750W that you actually want to put into your PC.

    Great, but if I use just one gpu, which one out of the two I mentioned is king?
  6. Before choosing between them, Check this out http://www.eggxpert.com/forums/thread/323050.aspx ;) Its a guide. In my opinion tho' Corsair TX is better than CX but more expensive. Check OCZ ZT 750W or OCZ Fatal1ty 550W 80 PLUS. Both are good :)

    I'd prefer the Corsair, but the CX series is just decent. An XFX 650 at $70 is a much better choice than the CX600M at $65.
