Is it okay for a load to go over wattage?

post #1 of 15
Thread Starter 
So my PSU wattage is 1000w, and after calaculating how much power my new components will use, it looks like it uses 1020w. Is that still okay? or will I have to purchase a new psu?
My specs are: I7 5960x @4.7ghz and 1.36v, r9 295x2, 1000w cooler master silent pro m2, NZXT Kraken x61, 6TB 7.2 HDD, 128GB SSD, Asus x99 motherboard.

how did you come up with 1020 watts? I'm not a complete expert on this but I don't think you are using that much.
But there are 2 experts here on OCN that will most likely chime in and correct me if I'm wrong. smile.gif

edit: shilka is one of the experts, glad to see you chime in on this shilka. thumb.gif

The so called calculator you used is wrong and is utter rubbish
Why all online PSU calculators are wrong and is total bogus

Your system is nowhere near 1000 watts.

There's no way you're even using 750 watts... let alone over 1000. You probably wouldn't even need more than 860w if you had TWO of the video cards of which you have only one.

Just so we're on the same page, I have the R9 295X2, not the GTX 295.

The 295x2 has a TDP of 500W, So 1000w is recommended for ONE 295x2.
post #9 of 15
TDP is not power draw nor has it anything to do with power draws
TDP is heat measured in wattage the chip is designed for not the amount of power it will draw

As for what AMD and Intel about their video card forget about that too.
Why the AMD and Nvidia power requirements are wrong

I will say that if you already have the 1000w installed then just keep in case you add more hardware.
I run a 1000w in my system as I used to run 2 GTX 580's and having the 1000w at the time helped me sleep better at night. biggrin.gif
