im looking to build myself a budget gaming rig and ive come up with 2 options in my price range and i would like to know what everyone thinks would be better
Corsair VS650 powersupply
now in the way of games i dont neccisarily want to be running at 1080p but i would like to be able to run games at a decent graphics level.
all these parts im buying from msy. i live in australia if u can find a cheaper place please let me know
You definitely don't need that much power. Even if you overclock your CPU so that it consumes a massive 200 W (very unrealistic) and the GPU consumes 120 W, and the rest of the components spend about 50 W then 400 W would be enough. But those numbers are quite unrealistic (put too high). I'd go with something like a Corsair CX430-m if I were you.
In general, the Radeon 7770 can handle games at 1920x1080 if the quality is toned down. The Radeon 7850, on the other hand, can handle many games at 1920x1080 with the quality cranked up. I hope this guideline will help you choose the right GPU.
I like the first option better, however I would swap the cpu out for either the 4300 or 6300 as vishera is a better performer zambezi clock for clock.
I also agree you wont need a 650w for a single low/mid end gpu.
