It should if your 4870X2 is a single card. If you are running 2 4870s it may, but you'll have to use 2 of the MOLEX power leads to the 2 additional PCIe pigtails to power the 2nd 4870.

The minimum PSU required just for those two graphic cards alone is 550W. Now, that leaves 100W for the rest of your components. I believe you may need to upgrade to a 700W. You don't want a PSU working 90% of the time, that won't be good.

Oh, I'm sorry. I assumed that X2 meant dual graphic cards. Then, a 650W should suffice.

What else do you have in the rig, your 650Watt PSU is cutting it too close to the requirement of the X2.

Having 2 HDDs a DVD rom and all the case fans on itself might lead to reboots.
The Links you've posted should be read.

Someone here used a 550 watt PSU and ended up with major issues too..... in 2008
The problem has not yet been resolved........

Have you bought the PSU?
If not, then go for a nothing less than a 750Watt 80+ PSU

Cos if you utilize the 650Watt PSU constantly at full load, it's not going to last too long.....
And could end up damaging other stuff. Also if you plan to OC... it's going to weigh on the Voltages.....
Recheck before saying "Solved".......
