Can I CF XFX 5870 w/ ASUS 5870 on 700W PSU?

[Spare-Flair]

I just picked up an ASUS 5870 on clearance. Is it safe for me to crossfire it with my existing XFX 5870? Both are 1GB models.

My PSU is the Coolermaster SilentPro 700M. The 600W model got good reviews from Johnny Guru. My 700W model has 50A on the +12V rail.

Should be just fine. I assume the PC in your sig is the one you'll be running it on?

If you want some advice I would sell both 5870 cards (Bitcoin miners are buying those specific cards in droves) which can go for up to $310 each. Buy some 6950's and crossfire them. MSI has some 6950 2GB's that unlock without issue on Newegg I believe as well so you could unlock those babies to 6970 spec.
