I wish you had revealed the make and model of the PSU. Also the rest of the PC. Sometimes folk pop in a dozen drives and my advice is blown.
While it's not a setup I'd sell the reason is that I want to have the final power at half the PSU's rating. In a pinch maybe 50% spare. In your case I'd have to put it on a Watt meter to tell how close it is.
I have a amd fx 6300 non-Oc'ed
I have a 1 tb HDD . I also have a 500 watt PSU which has only 32A on 12v rail .
I know that I made a mistake buying this local psu. But can I run the amd r9 380 I am about to buy .
BTW the PSU is Circle 500watt raw power
Thank you for answers
