Is it safe to use OCCT ?
Not saying it is not just asking.

My system is Intel i9 14900k and RTX 4090 plus a good amount of fans and a AIO.

Reason I ask is because last time I did a Power test, I think it is called, that testing power supply and mobo it used like 900 to 950 VA watts. I had a 1200 watt power supply but had to replace it. Replaced it with a 1000 watt power supply. Worried if the test uses 900 to 950 VA watts again it will damage my new power supply. Do I have a reason to be worried ?

You have the most power hungry CPU and GPU possible, I would not do that with less then 1200W.

Ok

No, you need 1200 Watts, otherwise you basically have no breathing room on the PSU @ full loads.

For a UPS backup you need at least 1500VA which is approx 900-1000 Watts.

You don't need a UPS that can handle the 1200 Watt PSU at 100% load, since you would never do that anyways. You buy a PSU larger then what you would ever need so you can avoid loading that PSU above 90% at any given time. The UPS needs to be able to handle "actual" power output.

UPS can't damage the PC PSU, however if the PC is under very high loads / power drawn from wall when the UPS kicks in, either the PC could shut-off if UPS is not enough to handle it, or you simply will have very little time to then properly shutdown the PC if the power goes out and UPS kicks in.

Please note that you also will want to run at least one Display (what you consider the Primary Display if using multiples) on the UPS as well, so you can still view the PC should the power go out.

So should I have gotten a new 1200 watt power supply instead of 1000 watt power supply?

:(

Hope not.

My RTX 4090 recommended 850 watts.

With that GPU + CPU + all the rest of the PC, that's like 900 Watts right there at full loads.
So yea you want 1200W, not 1000

Ok thank you.


Glad I have a UPS backup at 1500VA

What are you testing with? Just OCCT?

You might need something newer, more demanding to actually push that CPU + GPU at the same time to it's limits. Most tests won't push the CPU + GPU at the same time.

But yea you were no where near a full load if all you uses was 950VA

VA does not equal wattage.

As again you can look this up and I forget the exact number conversations but 1500 VA is around 900-1000 watts. So again at 900-950 VA you were no where near what your CPU + GPU can actually dish out when pushed hard. And I'm not even talking about any OC'ing, just what they do by default "out of the box"

With that CPU and that GPU you don't need to overclock anything.

You'll just have to deal with even more heat and possible instabilities.

i have a 13900k and 4090 w/12 fans 2-m.2 1 ssd and a AIO i rarely go above 600watts
under norrmal gaming conditions thats with gpu power management in nvidia control panel
on prefer maximum performance and power options in windows set to high performance
with a 1200 watt platnium psu.you should be fine.but if you can swap it out i would.and heat.. the 4000 series cards run very cool so
should not be a problem and the likely hood of your cpu ever going over 30% usage
is pretty minimal under normal use.(with turbo boost and enhanced in bios enabled as well)
and make sure your bios is updated and turn on the new intel base line profile.

You can still run it with 1000W PSU, but I would take extra measures.

I doubt you will have any issues as long as you have a quality 1000w PSU. The huge power draw numbers are typically synthetic benchmarks and who sits around running benchmarks all day. Real world use is going to be much lower. I have have a similar system, 7950X3D, 4090, (12) AL-120 fans, etc. I've measured the power draw at the wall over several days of normal use, gaming, renders, transcoding.... it barely breaks 700w at peak and thats with monitors, speakers, etc included.
