So basically I want to get a decent budget build and I'm not quite sure if the PSU I chose will be enough for my system. Can see the overall system here.
The PSU I chose is a Sirtec Performance Pro PP-550 550W 80+ Bronze with a single-rail 12v @ 38A, and should handle the HD7770 without a problem from what I know, but the thing that makes me doubt is the 125W TDP rating of the CPU.
Will this PSU be able to handle the system without a problem even on heavy load or should I try looking for a better one?
Well I had a cx 500 watt psu in my build with a 7750 and a 125 watt cpu, it fired itself due to overdraw and i had to buy a replacement. I would recommend around 700+ watts if you want some headroom and plan to upgrade/ overclock. If not the 650 range would be fine.
