Hey there, hopefully this'll be a quick thread.
I'm long overdue an upgrade, currently still running a 6850, which I imagine to most of the dwellers here is a bit like trying to run modern games on a potato. Certainly not handling metro on that, I assure you.
I was all ready to buy the R9 290 (XFX's version) when I noticed the reccomended power supply was atleast a 750w. Unfortunately I just bought a 600w PSU to replace my previous one a week ago.
So I guess my question is how essential is that extra 150 wattage, when I don't intend to overclock? According to OuterVision's PSU calculator it's reccomending 450w, though I'm aware that may not be incredibly reliable.
I don't really have any desire to buy another power supply so soon after the previous one, so if it's really a bad idea for the R9 290, I'm open to any suggestions.
Thanks.
EDIT: Forgot to mention, the PSU I currently have is a Corsair 600CX with Bronze certification.
