is a 750 watt psu enough?

mhirt34

will my corsair 750 ax be able to handle 2 7970/r9 280s in CF with a i7 3770k at a 4.6 ghz oc with full water cooling? Im trying to figure out if I have to adjust my budget for upgrading my set up.

As long as you aren't overclocking those 7970s to the extreme, 750w should be enough.

I know I should look for more headroom, its just that if I go for a new psu im going to have downgrade something in my loop, since I have to get a second rad with getting a new gpu. I also dont think my xspc bay res/pump d will be able to handle a cpu, x2 gpus and 360 and a 240 rad.

Yes. 850 if you want more clearance.

No need. The ax760 is plenty.
