Look for proper reviews, try to find out who the OEM is, what platform they use, what components they use(caps, fan, etc), see how well they regulate under various loads and if they can deliver their rated output inside specifications, look at the output quality(noise/ripple), so on and so forth.

It will run 2x 6870 with all the overclocking you can achieve under air/water cooling.

you will be fine seriously, don't let people scare you off. You system will never put enough load on the GX 650 to blow everything up. You computer will never be at 100% load even when gaming. Unless you fold/prime 95 24/7 it will never push to load, even at prime95 it never utilize the gpu at 100% and vice versa for gaming for the cpu.

XFX are good because they are same units from seasonic or some big company i forgot. OCZ is a hit or miss brand just like the coolermaster line ups, so its not really an upgrade.

If you are 100% paranoid about your GX 650 look into Corsair, Antec, Seasonic, Silverstone, and XFX.

You might be disappointed later on after a new psu and another 6870, as you might not get much of an improvement due to your cpu.

but then i know this is one step at a time for upgrades.

but if this was up to me, i would spend the money you would for a psu and a 6870 and use it for a new cpu/mobo combo. Get a decent heatsink and learn how to overclock your cpu.

the 6870 alone can max out any game right now except for bf3/crysis 2, but your limiting factor for the other games is your cpu not your gpu.

Many people ran CrossfireX 5870's on a 600W ModXstream with no issues, just make sure the PSU is SLi/CrossfireX compatible and you should be good.
If it isn't, look up its actual power ratings and output and reference it here to see what you will need.

There are many, many games a 6870 can't max out at 1080P.

you'd be pushing it, especially if you overclock the CPU.

He's running a coolmaster 650w. Doesn't anyone in here every bother to read an OP's sig rig before asking what parts he owns? Jeez.

Personally: I'd upgrade to 850w. Never can be too safe.
