How many watts does your PC really pull when gaming? got UPS?

[arknor]

12700k + 4090
Game Cyberpunk @ 3440x1440 120hz, I had DLSS or whatever and frame gen on.
probably how most people game

Also have 2 speakers pulling about 30watts each at low volume (both have built in amps)
34inch ultrawide monitor that seems to pull about 50watt in SDR and an extra 70+ in HDR
BT Smart hub that seems to pull 0watt
so real load is probably about 100watt less


I doubt my PC's PSU alone could ever pull 700watts unless I tried gaming at the same time as CPU and GPU benchmarks

PC on it's own pulls around 90-150 watts browsing the web and watching youtube.

so I guess the most important part of the efficiency curve on a PSU in reality is going to be
low end of 100-200 watts netflix and chill mode
around 300-600 when gaming.

and no one probably needs more than a 900watt psu as a gamer

The key thing to me is you don't want to over draw any single rails output. If you try and draw 30A from a rail that can only supply 20A then you're going to get issues whether the total load is below the PSU rating or not.

isn't that what people were seeing with high end cards either this or last gen, some PC's were just shutting down during gaming because the PSU's couldn't handle a big mini spike in load.

I'd imagine any current gen PSU has the capacitors etc to deal with it.

Trying to monitor my UPS whilst gaming It didn't ever seem to have spikes in the load, so I'm assuming any or smoothed out by capacitors in the comps PSU..


Really surprised by how low power the PC is just browsing the web or watching videos, almost tempted to get an old PC out and see how high they idle..


also if any of you have a UPS what current are you seeing? mines anywhere between 239-245 volts depending on time of day.

I guess my areas electric grid didn't get altered since 2000, when we switched to 230 +10% -6% or whatever it is

Possibly, could also be the spikes are much smaller than your UPS's sampling rate or the sampling method could be average over the last x seconds. Mine only updates the display roughly every 5 seconds.

HWinfo seems to poll the UPS more often as the number doesn't match the number in my UPS software.
I guess it's possible to setup an OSD through HWinfo that shows the watts on screen

Seems having hwinfo sensor panel open shuts out nvidias own OSD though as all the numbers on the NV OSD say NA or null whatever it was if HWinfo is open

monitor datasheet says 88W so I suspect there's some measurement misreporting or inaccuracy.

will depend on brightness, contrast, refresh rates and other settings on your monitor, as well as what colours it's displaying at the time.

My intention is basically to just have my pc and my nas attached to the ups, So would I be perfectly fine getting something which is rated for 750 to 800w? Or is even that overkill?

perfectly fine, you realise a UPS will only provide battery for 5-10 minutes right? enough time to safely shut your PC down, well maybe 20-30mins if you only browse the web

you don't really need one in the UK, unless you live somewhere with power issues.

unless your spending over £1000 then they are all line-interactive UPS
mine only intervenes if the power drops below 180volts or goes above 260, although I think they still do some EMI/RFI filtering

They really are a waste of money on our power system.


I have the UK version of https://www.cyberpower.com/eu/en/product/sku/cp1300epfclcd I got on ebay sold "as new" I think they are about 250 on amazon for the same model.

There's also another aimed at gamers

https://www.amazon.co.uk/APC-Protector-Consoles-Midnight-BGM2200B-UK-black/dp/B0CW6H8W57

which has even worse tolerances than the one I have, only kicking in if the ac mains voltage going outside of 179-293

I've never seen my input voltage outside of 239-245 so far.


the really good ones are double/triple conversion which is expensive.

How does line-interactive stack up vs double online conversion UPS. Taking in AC, converting to DC, then back to AC, double conversion UPS provides a cleaner, more consistent signal.

I think the APC smart range are double conversion as long as you turn the eco setting off

maybe you can find one second hand somewhere that just needs new batteries for super cheap.
I'm up North so the second hand market is grim up here, looks like down South it's easy to get good deals though.
Companies must be getting rid of them all the time, they are heavy as hell too, even my small one is something like 12kg

The good ones are probably 15-25kg, although you can take the batteries out and not move the whole weight at once.. but it's not exactly economical to post them, I bet there's a lot of "Collect in person" adverts with UPS that cost 2k+ new going for a few hundred and all they will need is new batteries
