post #1 of 7
Thread Starter 
I have a V1 TX750 bought in 2010. i was wondering if it could power my sig rig plus one extra 7970. if it can't can you guys recommend me a a new psu. reason for asking is i plan on getting a QNIX 27" monitor and i feel i would need the extra power to run bf4 maxed and maybe overclock the panal.

I honestly didn't think it'd be enough shilka. I've ran several power configurations with my setup which is similar to his, and it's always landed me near the 950w mark. The only reason I say this is because I'm wanting to do the same thing but I knew my 800 watt may not be enough.

Only part of that video where he is wrong is that part about efficiency

The original TX750 is a great PSU, and should be plenty for 7970 CF.
