Is this power supply too small now?

This is what my computer started off as. PCPP has the power consumption listed as 716W.

This is what my computer grew to over the course of 1 year. PCPP has the computer drawing 839W of power - this doesn't account for: -2 water pumps (each 5-37W of power) - A fan controller that I'm looking at installing in one of the 5.25" bays. - as well as a 6 bay hot-swappable SSD cage for one of the 5.25" bays.

From what I can tell, each of the case fans actually only draws 0.6W not the 5W that PCPP suggests. I'm wondering if the PSU is too small now - keep in mind I'm getting a UPS in case of power outages. So I'm totally screwed no matter which way I look at it. if I upgrade the PSU I have to upgrade the UPS. I'm also running the three monitors off of the UPS.

That wattage is when every component in your system is at max load. And like you said thosee fans will never run at 5W each so i would say that it won't be a problem. But i wouldn't recommend overclocking anything tho.

try doing some benchmarks and see with corsair link what the maxium load is.

See. that's what I thought. every once in a while I come across reviews on the 980Ti - found one today that gave recommendations on PSU based on single card and SLI. the recommendations were 600W for single and 900W for SLI. and that's without figuring in the 10 - 74W for dual pumps, and the 10.2W for the 17 Noctua NF-F12s. mind you I'm removing the HDD when I finally finish off the computer with liquid cooling. PCPP has the HDD drawing 20W.

EDIT: the overclocking is what im worried about. I bought the unlocked chip to give me the option of overclocking when it begins to slow down - now I know that's years down the road. but im trying to take advantage of the fact that my brother is currently building a pc as well. he is looking at buying a UPS. so my though was that if I need to upgrade my PSU and UPS I would simply sell him my parts. I would sell him my PSU at the same cost as what he paid for his PSU ( I take a $100 loss) and I sell him the UPS to go with it at the same cost I paid for it. mind you I would have to upgrade my PSU which would set me back $280 + 13% tax, and a new UPS which would set me back $700

600w for 1 980ti isn't that crazy. The 980ti is a pretty power hungry card even more now when compared to the similarly performing GTX 1070 and it can peak above 300W by itself and with a 500w PSU, it could be a problem considering most of these are often matched with overclocked CPUs like a 6600k and several additional devices.

yep correct.

no, 600w with a single 980ti is crazy. could see a system with a highly overclocked/overvolted 980ti classified and a max overclocked i7 5960X using over 500 watts gaming load. 600w is just a recommendation, like how the 290X would say 750 watt, then you peel off that sticker and it said 500w on the box.

I don't think Corsair Link is compatible with this PSU. Corsair link is with the digital version of that PSU.

its because your link says HX850i. And i in HX850i is for link.

ok. I just double checked my original receipt for the components that I purchased. I did indeed purchase the HX850i. thank you for that little piece of information. I will look into that once I get home.

greatly appreciate all the help. I will post the results and go from there. because I built this rig with expandability and overclocking in mind. so if my power draw is fairly high - I may have to look into purchasing the HX1000i

You still have plenty of wattage. PCPP isn't always accurate.

https://www.youtube.com/watch?v=IHzHxshus9c

You would likely use around 600 watts at the max so you would have plenty of headroom with a 850 watt PSU with your build.

thanks. I actually used the Corsair link program. and without the pumps in the equation. I ran 3D Mark Stress test "Fire Strike extreme Stress Test" and with that test running and doing research on the internet at the same time - I managed to pull 750 watts

I would move to a 1000w - 1200w unit if i were you.

I know I'm pushing the upper limits of my power supply, but I think I will live with it. Using the corsair link software that's part of my PSU shows 750 as peak wattage while running a GPU stress test and surfing the web simultaneously. I have just enough headroom to add in the two pumps and a mild over clock on the cpu

It should be alright. If its not you will notice random shutdowns so as long that doesn't happen all should be fine.

Thanks to everyone and their comments and input. after using Corsair Link software a second time I realized I had been reading the wrong number. While using 3D mark and running an extreme stress test on the GPU's with the fans on them full blast and all my case fans full blast - the power supply was only outputting 650 watts to the components. so I have 200 Watts headroom to allow me to add two Laing D5 pumps, NZXT Hue+ LED strips, and overclocking the I7-4790k, with possible minor headroom to possibly overclock the 980 Ti's even more.
