Power consumption on 3rd gen i5 CPU?

My dahua nvr is far too noisy. Also I find the user experience and interface with it quite average. Soni am hoping to move to a PC withBlue Iris.

I have read the notes on Blue Iris and recommended hardware, and have managed to find a Intel Core i5-3570 powered Optiplex, that I'm sure will run my three starlights, at least from reading the wiki.

However, i wonder if I should be going for a more efficient CPU to save on electricity bills? Would any of the more experienced and competent have an idea of the payback period of a third gen, versus say a 6th gen ( that would cost me an extra 300 USD where I'm from) given my current 3 cam setup ( I may move to 4 cams in future, but not more than 5).

Thanks

I run 8 cameras with that same cpu (12 FPS, 4-4mp, 4-2mp direct to disk, no overlays) on my home BI machine, and it sits right around 25%-30% utilization. Kill-O-Watt shows about 85 watts steady state and goes up to 100w if I'm streaming.

That's insanely high power consumption, it can't be for the pc only.

Yah sorry, that’s total system. Cameras + poe + computer + (probably not very efficient) Eaton 5px UPS.

I’ll try to see if I can get around to hooking the pc by itself to the watt meter in the next few days and post the results. It’s been on my list of things to do for a while, albeit pretty low because the list is long and only ever seems to grow.

I have an it i5 3450 (optiplex 3010) and the computer draws around 50-60 watts when I checked it with a power meter. That was with 4 or 5 cams. CPU was about 15-20% back then. I've got 9 cams now but haven't checked consumption. Hope this helps.

That's a very high number... something else must have been connected or a video card.

I’ll have a full set of numbers coming soon. Had to stop testing for dinner. Be back in a few...

Okay - Here goes:

System:
HP 8300 Elite small form factor - with an i3570 CPU, 2TB hitachi, 4TB WD Purple, Startech.com Gigabit PCI ethernet adapter (2nd NIC).
Also powered by the computers USB ports:
Logitech usb camera & small 4 port gigabyte switch. I couldn't see a noticeable drop by unplugging either of them, so I assume it's less than a few watts each.

Cameras:
3x Hikvision 2CD2142FWD-IS (4MP)
3x Dahua IPC-HDW4231EM-AS (2MP)
1x Amcrest PRO-HD (4MP)
1x RCA Crap Doorbell (2MP)
1x Logitech 720c (I think)
1x Dlink 5222LB (Floater camera for the dog when we're gone)
All run at 10FPS except the Logitech (15fps) and the doorbell (12FPS)
D2D & no overlays
Motion analysis on ~240MP/s = ~25% Cpu according to BI

POE switch is a BVtech 8 port 120w.

UPS is a Eaton 5px 3000 (way too much, but the price was such I had to take it plus I've got plans to power more than just this server with it)

All measured with a Kill-A-Watt P3-4400 (and verified against the Eaton built in load monitoring.)

Okay, the numbers:

Eaton UPS powered in float mode with no load = 24W (It powers the inverter full time for rapid switch, voltage and frequency correction)

Cameras + POE = 30.5W

HP 8300 boot process = 40-50W
@27% BI usage = 51W
@25% BI usage = 48W
@20% BI usage = 45W

Total system measured on the plug for the UPS with everything powered by the UPS = 95-105W (depending on battery float status I assume) ~ $85/yr here currently.

Bonus - The old Dell E193FP (19") attached to the system uses 28w, but it's not normally powered.

Note you have two drives in there. Here is a fourth gen i5-4590 with just an ssd and an efficient power supply
PC NVR Power Consumption Sample
This is an 8th gen units idle at 6 or 7w and max out at 75w under full 100 percent cpu and intel gpu load

That thread is a good read.

Yep, looks like the extra drive may be adding 10w. From a little google fu, a read/write on SSD is around 5w, but they can instantly go idle when they're not working, so would be a bit of a savings. Around here currently that would be about $8/yr.

I think a bigger gain would be adding a good PSU. I can't remember what's in it, but I'm sure it's not gold rated. That's could possibly pay for itself in a year.
