Should I Upgrade?

[GMart84]

Currently using a Corsair HX1000i to power my system, but I am wondering if I am going to run into a problem upgrading the pumps in my water cooling system.

 

i9 9900K 5.1 @ 1.29 vCore - 160-200W in Aida64 - 180W

2x GTX 1080 Ti - 250W TDP (I have seen full load numbers higher so for my estimation with OC I was thinking I should go a little higher than the TDP) - 300W

120 LEDs in 12 strips Corsair Strips - 10W

10x LED Fans Corsair LL Fans - 3.6W max each - 36W

5x Corsair ML Fans - 2.7W max each - 13.5W

8x Artic Fans - 2.9W max each - 23.2W

Rest of system - 50W (this is likely an overestimated number)

 

180w + 300w + 300w + 10w + 36w + 13.5w + 23.2w + 50w = 912.7w

 

I want to replace my Watercooling pumps which according to the manufacturer maxed out at 7.2w each with Swiftech D5’s which max out at 37w.

 

912.7w - 14.4w + 74w = 972.3w

 

While I know this is below the rated 1000w my PSU can handle am I getting to the point where spikes in CPU or GPU wattage during gaming could cause issues?

 

Also I know I have made mistakes before in PSU estimations so it I am still way off please help me understand.

So all 23 fans will be spinning at 100% RPM and all of the LEDs on the strip and in the 10 fans will be white and at full brightness?

@jonnyGURU at some point it would be but not 24/7.  I was using maximum values for that exact case, but more often than not they will be around 60-75% PWM and the LEDs will be in Rainbow mode.

 

In that case I would lower the power draw down probably 30-40 watts.  I do quite a bit of benchmarking and video encoding as well as gaming that goes keep the CPU running at least at 165w spiking to about 200w and the GPUs really only get worked while gaming.

 

Running 3DMark the system wall pulling up to 800 without the LEDs on.  At least that was what iCue was reporting.
