Hi everyone. I was thinking in adding another gpu to my rig. I'd like to buy a R9 280X and use it on my rig, which has an OC'ed 3570k @4.0Ghz (core voltage goes from 0.9 to 1.15V), an OC'ed 7950 (actually the card it's undervolted from the stock vddc), 2 3,5" HDDs, 1 SSD, 1 DVD, 6 fans (5 are 120mm and 1 is a 200mm) and a Asus DGX sound card, all this on a XFX 750W (Bronze) PSU.
I checked on the site where you can calculate the wattage of your rig, and it was 566W even with the R9 280x (if i put everything right on the page): check

Since i use my PC as a gaming pc and also as a mining rig (i do gpu mining just 4-5 hours per day btw), do you think that my current PSU should be enough to run another gpu (the r9 280x), and keep doing the same things as i do now? Thanks a lot.
