Is 650W enough for my system? PSU getting pretty warm.

post #1 of 7
Thread Starter 
Just rebuilt my system and i noticed my PSU is getting pretty darn warm and i was wondering if 650W is enough or if i should be looking into getting a 750W or more. CPU will be here in a few days and i will be pushing for 4.8GHz 1.3V~ and i have my 1080 at 2114MHz with 100% voltage and 120% power. everything else in my system is exactly as it is in my sig rig.

Your PSU is good to go. Just make sure the fan on it is working. The new Corsair system (OC capable) has an i7 7700k and a 1080 GTX and only uses a 400-500W PSU.

Oh wow, before i posted this i did the PSU calculator thing and it claimed i needed 988W minimum (clearly broken) so i was getting really nervous. The fan is spinning but it stops and starts so its not getting hot enough to keep it spinning i guess.

Your system does not even draw 350 watts and as far as all of those so called PSU calculators dont use them as they are all wrong and rubbish
http://www.overclock.net/t/1598887/why-all-online-psu-calculators-are-wrong-and-is-total-bogus#post_25118372

If not for the fact that the HX650 only has two PCI-E cables you could add a second GTX 1080 and still use less then 600 watts.

my 1080 pulls alot more power than a ref 1080. It has 2 8 pin and the TDP is 245W should still be ok right?

TDP has nothing to do with how much power the card draw
TDP is short for thermal design power or how much heat the card can withstand measured in watts

And 650 watts is more then enough for ther system you have.
