When I build my gaming PC in the near future i'm going to get dual Radeon 7850's. I need to know if this is a good PSU for that.

Things it needs to power:

I5 2500K
x2 7850's 1 GB
3 120mm fans
Corsair Vengeance 8GB
AS Rock B75

Also on a side note, what do you guys think about this PC for my first build? 1 being *** and 10 being amazing.

The power supply will work for two Radeon HD7850's, I would also get a Samsung 830 ssd for you operating system and antivirus, and a regular sata hard drive for your games. When you load your system leave the sata hard drive disconnected until the operating system is installed.

I would not crossfire with a pair of lesser cards, I would go for a single powerful card like a 7970/7950 or a GTX660Ti/670. Any stuttering issues are compounded by dual cards and there are games which actually run worse with dual cards.

Aside from that, I would be looking for a 700W+ supply for crossfire. Your 600W supply is more than ample for a high-end single card.

If you've already got it then there's no need to change it, as it is more than enough for a system with two 7850s. However there are better choices if you haven't bought yet.

A Corsair TX 750 V.2 isn't a bad option, but in terms of just everything; heat,power,room I would go for a single card because those cards roughly together are about 400-440 depending on the manufacturer with that I would get a more powerful card like a 670,680 or 7970, 7950 It will do you much better.
