Did I get the wrong PSU?

[RyanTScott]

Specs:

1950x
Enermax LickTech 360
x399 Taichi
128gb DDR4
1xGTX 1080ti
2xGTX1080
1xSAS RAID Card
2xSSDs
5x7.2k SATA
1xBluRay Burner
10x120mmFans
EVGA SuperNova 1200 Platinum
CyberPower 1320w UPS

Usage:
Professional, 8-12hrs a day VIdeo Editing, Compositing, 3D Animation and Rendering.

I picked the PSU above using CoolerMaster's PSU calculator and 1200 was its recommendation. However I would like to OC and I didn't take that into account when calculating. After upping the volts from 1.1 to 1.3 the calculator recommends a 1500w. What's confusing is that using my UPS's load monitor the system idles at about 224w and shoots to around 400w when doing a video render. When using the GPUs to render 3D it goes to around 600w. Running prime gives a steady 380w...

Did I pick the right PSU? Do I have room for a modest OC, somewhere between 1.1 and 1.3v?

Thanks!

You're fine to overclock. 1200W is a LOT of wattage, and that build still won't use even close to all of it. It's also a high quality PSU, so no problems there.

1| You should be fine with what you currently have but might I ask what you mean by a modest overclock?
2| Might I also ask how you got 1xGTX1080Ti and 2xGTX1080's in there? You should've gone for a 2xGTX1080Ti setup which would've netted you a better result.
3| You didn't mention the case's make and model.
4| The CPU volts aren't the only real factor, you also have to deal with the rest of the component voltages and higher clocks would also mean higher heat output.
5| You could put this doubt to rest if you had a Kill-A-Watt meter to test your system's power draw when everything is at stock clocks.

online Power supplies calculator have very large safe factor ... you will be ok with 1200 watts power supply because you will not fully load all the components at the same time ...

1. Modest OC = 3.6ghz - 4.0ghz @ 1.2 - 1.35v (give or take...)
2. I already had the 2xGTX1080 and because I wanted to run a hardware raid I only had room for one additional GPU on the Taichi.
3. You are correct. It's a Phanteks ENthoo Primo
4. Also correct.
5.Good suggestion. How would you say a Kill-A-Watt compares to my UPS's Software Monitor?
