7770's use about 80W at full load, so with 2 of them consuming ~160W, you would still have a lot of headroom. Note that a 7970/7950 > 2x 7770s, especially when games don't make good use of Crossfire or if you want to run games in Windowed mode (CF always needs fullscreen mode).
As the reviewer mentioned, a lot of PSU companies will down rate their PSU. I think my Seasonic X750 can go as high as 850~900W.
Welp, didn't know that stock clock for a 8350 was 4GHz. What happens if something is *close* to 450w at full load(like 370w)? Will it get unstable?
I want to upgrade as soon as I can, do you have an idea of what the best CPU and GPU I can put in it are?
Sorry if I sound rude
Your PSU is rated for something like supplying about 440W on 12V at 50C guaranteed.
That review says those 370W were measured at the wall. Depending what efficiency their PSU had, that's a good bit less used by the parts inside the PC. Look at this:
370W * 90% = 333W
370W * 85% = 315W
370W * 80% = 296W
It's pretty far away from the limits of your PSU.
EDIT: This is in the specs of your PSU:
"Maximum Power: Continuous 450W@50°C"
Both CPU and GPU use 12V, and nearly all of those 450W at 50C (122F) can flow into them just fine:
12V * 37A = 444WEdited by deepor - 9/12/13 at 1:12pm
