PC system max power draw?

[JIWIL]

You can do a lot in the bios to get the power drain down and also in Windows. I have around 60-65W {monitor not included} idle. Measured with a T-RMS meter. Those cheap Wattmeters you find everywhere are only good to measure a resistive load. Switch Power Supply's it does a very bad job, and you're not sure what you measure. Do the test, put in the wall and connect a small Phone Charger in it without any load connected. Does your Wattmeter shows about 1W to 7W or more, then you have a cheap meter that can only measure resistive loads.

A good T-RMS meter will show something around 0.1 or 0.3W even less, for a charger without load connected. More then 1W is impossible because at that power draw it would burn up itself...

The readout on these UPS' only moves in 5w increments, is why I made that earlier statement about it not be particularly accurate, but 'good enough' for my use.

The thread isn't meant to be a scientific project. I got my meter for around 15EUR, OFC it's not accurate.
You have proved your point, now please stay on topic and have fun.

My breaker is at its wit's end! I'm like 200-watts below the 1500-watt limit.

It's a big room with lots of screens and two computers on one breaker. I'm pretty sure I cant trigger it but another power hog might do the trick.

 

[Fokker]

140W? Damn, that can't be right... My system uses only 60-65W idle... Are you sure you measured with a TRUE RMS Wattmeter? Those cheap stock Wattmeters can't measure exactly from a Switch Power Supply.

I'm going by what the PSU reports. 12700K, 3080 FTW3, 6 case fans, a water pump, and a bunch of lite brite.

I used a P3 to measure this a few times just because I was curious about it.
The Athlon 64 box pulls 43-48W and is on 24/7, averaging 1047W per day.
The FX-8370 rack pulls 65-225W outfitted with two disks and an SSD among other modules, pulling north of 1825W per day.
My Ryzen workstation pulls 113-295W with its fully designated loadout including an aging RX 580 and SolarFlare cards. No HDDs. It can climb up to 3790W per day.
I'm about to break the trend of that last one by switching up to a RX7900 XT.

Got two more results from Ubisoft's recent releases. Highest recorded momentary values for the built-in benchmark in maxed out native 4K + TAA:

Game	Uncapped frame rate [W]	60 fps cap [W]	Difference [%]
Assassin's Creed: Mirage	447	368	-18
Avatar: Frontiers of Pandora	461	443	-4

A good T-RMS meter will show something around 0.1 or 0.3W even less, for a charger without load connected

My meter shows 0.0 W.
According to the manufacturer, its tolerance is +/-1% (and +/-1 W) across 1-3000 W load, with maximum deviation of 4% over 2500 W. And testing power consumption even with a basic meter can offer insights into ways to limit its usage.

And testing power consumption even with a basic meter can offer insights into ways to limit its usage.

The issue with basic meters is that they typically use an integrated circuit that measures power usage averaged over a 1 second timespan. Actual power consumption can vary by a significant amount, particularly where a graphics card is involved. But for relative readings they can be OK.

-----------------------------------

1st uncapped run was for the sake of the thread, I always run the game capped at 62fps with 366W TBP (helpes trim the high peaks on power)
Feel free to check also CPU/Vram/GPU/PSU temperatures and fan rpm of all components.

What a waste of power on first run, let alone the +noise. +185W avg socket power for a completely unnecessary (to me) 90+fps
The game feels as smooth to me at 62. I'm used to play at 30-50fps without VRR in past, so...
The GPU has the power when needed for much more demanding games.
Next on my list is CP2077, but after I finish FC6

It would be a good idea to test old (DSR), ugly graphically, or badly optimised games, tha make the GPU/CPU (aio wc) fans crazy, like : Pathologic 2 (oh yeah, this one)...

... so we would know if it takes a lot power too !

Starfield is a perfect example, both ugly and badly optimized

 

[Beginner Macro Device]

[System specs 1] a.k.a. DLSS: Around 380 W + whatever percentage due to <100% PSU efficiency.
[System specs 2] a.k.a. YOLO-PC: Around 340 W + <100% PSU efficiency accounted.

Both measured at full tilt (Cinebench + Furmark simultaneously) using HWinfo readings. Of course it's far from accurate, yet I don't have proper measuring tools. Both consume ~30 to 40 W at idle.

The only reason I care for wattage is I don't wanna get my PSU explode. Electricity is $7 per 100 kW where I live and it's cold 70+ % of the year.

 

[A Computer Guy]

Anyone have a recommendation for one of these using US 120v?

I have it on good authority from Todd that you just need to upgrade your computer.

I've seen 450W avg power draw when running 3D marks's Timespy graphic tests on my system according to my CCI Pty Ltd power mate. This on a system with factory OC GPU & custom PBO settings on my Ryzen 7600X box.

However, when running 30 + mods in Skyrim Anniversary edition at 1440p with maxed out graphics, the system avg 250W. So I'm happy with that cause' 144Hz monitor maxed out.

PeakTech 9040 (wireless)
0 W without load connected
0.2 W with a second transmitter connected to the first transmitter.
The same result obtained when reversing the transmitters.

The receiver is powered by batteries.

just google killawatt and you will find a bunch of listings for ones like it

Just looked at my UPS, 410-440watts in watchdogs legion, ultra settings + RT on medium. that includes my modem and 2 routers which modem and 1 router is around 11-18watts between those 2. last router is just a 1gb switch so doubt its more then 2-5watts if that. Not sure what my monitor uses off hand

Yes you can. Buy a better one

I have an old Blueplanet EM100 that seems to work fine. I just use the one in my UPS now.

Yesterday I saw one of the Unigine benchmarks eating 580W.
Also these:
Days Gone 160FPS 570W
Age Of Wonders 4 120FPS 560W
Warhammer: Rogue Trader 120FPS 580W
Red Dead Redemption 2 130FPS 520W
Microsoft Flight Simulator 75FPS 575W

Indicates that my GPU OC push the system to a 580W ceiling.
