Hi - the 7770 uses a little less power than the 4850, so if your psu has been running the 4850 ok, it will also be fine for 7770.

Plus you get double the VRAM. http://www.hwcompare.com/11970/radeon-hd-4850-512mb-vs-... | Report abuse Reply to clutchc Ask the community Post an answer Tom's Hardware>Forum>Components>Hd 7770 PSU req> Related ressources: ForumHD 6850/70 or HD 7770 for Diablo 3, movies - on a brand new system ForumAMD 7750/ 7770 or 6670/66xx ForumIs 3gb RAM ok for the HD7770 ForumCorsair cx 430 psu enough to run phenom x4 970 and hd 7770 ?
