Hey guys. I've begun putting this build together, but I'm getting worried that my 750w PSU will not be enough to power it. PC Part Picker places the overall wattage (non-OC) at 391w. However, I've heard from some that you may need double the wattage, and I'm also not confident in the accuracy of most calculators, so I was hoping for your opinions.


Here's my build:

I got the PSU at a relatively cheap price and unfortunately I can no longer order. That said, if you guys recommend that I upgrade, I can always bite the bullet and pay for the return/restocking fees.

Any help would be great

Thanks for the help. Do you think there's enough clearing to SLI down the line, without overclocking?
