Hey all! I was wondering if my PSU is enough to support another GTX980 in SLI, at the moment I am rocking:

Gigabyte WF3 GTX980
I5 6600K <-- But quite heavily overclocked @4.6GHZ @1.39V (problem?)

The PSU I have is a cooler master G750M, I know it is not the best, but at the time I knew very little on PCs and thought wattage was all that mattered (Doh)

Is this PSU okay enough to support another GTX980 in SLI? I know 750W CAN be okay with good psu's :s

Thanks in advance :)

Thank you for your reply!

I'll tone it down as 4.5GHZ uses almost stock voltage! Yeh this PSU will need upgraded soon, it makes a very odd buzzing noise occasionaly - I can only presume this is very bad! At least I can shove this extra 980 in until the upgrade - thanks again
