is my evga p2 850w powerful enough?

[romeooscarbravo]

As per the title.
I currently have two EK d5 pumps which will run two loops and a GTX 1080ti FTW3, I'm contemplating picking up another graphics card, I also have 11pwm fans, 4 ek vardar 140mm 2000rpm and 7 ek vardar 120mm 2200rpm.

Will my current psu evga p2 850w power all of this without any issues?

Yes you will be fine. The latest gen gpu's are very power efficient.

If you want further confirmation look at Ace Modders post in the link below.

Single card goes up to 285W class with peaks over 300W.

Water cooling pumps typically consume something like up 20W per piece so they're not that big factor.
Fans are watt or two at most unless they're running at high speed.

With single graphics card you could easily have overclocked CPU with good power reserver.
Obviously with max consumption of graphics card being that high with two of them situation becomes different.
(unless CPU is sub 50W TDP one)
