My PC's power consumption

Hello, guys!

I tried this calculator http://www.extreme.outervision.com/PSUEngine and and it showed me this:

System Type: 1 physical CPU
Motherboard: High End - Desktop
CPU Socket: Socket LGA 1150
CPU: Intel Core i7-4770 3400 MHz Haswell-DT CPU
Utilization (TDP): 90% TDP
RAM: 2 Sticks DDR SDRAM
Video Card 1: NVIDIA GeForce GTX 780
Video Card 2: NVIDIA GeForce GTX 780
High rpm SATA: 1 HDD
Flash SSD: 1
Drive DVD-RW/DVD+RW Drive: 1
Drive Fans Regular: 1 Fan 140mm; LED: 1 Fan 120mm; 4 Fans 250mm;
Keyboard and mouse: Yes
System Load: 90 %

Minimum PSU Wattage: 631 Watts
Recommended Wattage: 681 Watts


Do you guys think it is correct? I thought that 2 gtx needed more power. I ask this because if it is correct, I will buy a CORSAIR AX860i.

Thank you!

  1. Hello!
    The EVGA Supernova G2 850W is a better choice than the Corsair for your build, it has better ripple suppression, voltage regulation and is cheaper. :)
    Yes, 631W would be enough, but 850W will allow you to OC without any issues.
    Best of luck! Let me know if you have any questions. :)
  2. i'd go 750W + for 680x2 600 for 770x2,

    http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_780_Ti/25.html

    269*2 = 538W leaving 210W for everything else (i7 = 84W) which is plenty of headroom.

    so your corsair will be fine.

    Sorry 269 is for a 780ti, it's 222 for a 780, so 650-700 would be fine.
  3. With 2 780's I always build with 1000w.

    Here's a can't beat DEAL on the EVGA 1000W G2.

  4. While 1000W wouldn't be a bad idea I think you could get away with going for a 850Watt. The Evga SuperNova 850G2 is a much better PSU than the corsair ax860i imo. I had the ax860i and it developed a coil whine..and so did its replacement..so back it went.

    although the price for that 1000W isn't bad at all.
  5. Thanks for the fast answer, guys!

    Unfortunately I can't choose that much. I live in Brazil and it's really hard to find good PSUs here. The corsair AX860i is an easy one. I found Evga supernova 850G2, but the 1000w is nowhere to be found.

    So do you guys think that both PSU (corsair and evga) will do just fine? I will not OC. I just like to play games at max :D
  6. Best answer
    No overclocking and you will be fine.
  7. Thank you all!
  8. Glad to assist , thanks for posting. :D
