Well, that PSU "might"run your 7870, but the risk of a big kaboom is huge..
Specific numbers for a PSU?. Let's see: from a good brand, like Seasonic, XFX, Corsair, Silverstone or another good one; for your system specs an future upgrades, around 600-650W; with "only" one +12V rail (despite some units have more than one, don't pick one); 80Plus rating, let's say Bronze or Silver (Gold or Platinum are bestest); and with at least 60A on that +12V rail..
Why the 7870 uses 2 6-pins connectors?. If I remember correctly, because uses a big PCB, from the 7900 series I think, and those uses 2 connector to properly power that card..
Please, one advice: don't be cheap on choosing the PSU. It's the heart of your system, now and the years to come, so don't risk your PC for saving a few bucks..
