netter safe than sorry.

We can't Benchmark like we used to, but we have our ways. One trick is to shove more GPUs in your computer. Like the time I needed to NV-Link, because I needed a higher HeavenBench score, so I did an SLI, which is what they called NV-Link back in the day. So, I decided to put two GPUs in my computer, which was the style at the time. Now, to add another GPU to your computer, costs a new PSU. Now in those days PSUs said OCZ on them, "Gimme 750W OCZs for an SLI" you'd say. Now where were we? Oh yeah, the important thing was that I had two GPUs in my rig, which was the style at the time! They didn't have RGB PSUs at the time, because of the war. The only thing you could get was those big green ones.

No. YOu don't need a 750w PSU, 750ws are reccomended for guys/girls with crap PSUs that are rated for 750w but in reality they don't output that much, with your PSU you should be more than fine.

750W is overkill.
600W is perfect.
550W is okay.
500W is close but manageable.

EDIT: Do as I say, not as I do. I did not have an option for a 600W ._.

I 100% agree although a good quality 650W might be even better. I believe the PSU isn't worth cutting corners on, and it's nice to know you have some watts of buffer. Once you begin to think about using the system for multiple years and PSU cap degration and such, I don't see a reason to get something that is iffy in quality or wattage, you are saving maybe $20-$30 but a good PSU can last a decade so it's not a bad investment.

if you're going to overclock the gpu and NOT the cpu, 600w would be the minimum i'd go.
