Any preferred source for UPS for BI PC/PoE Switch?

Honestly, I'm not sure what the max watts is- it would be a HP Prodesk, PoE switch, 4 cams currently with more coming, and monitor/keyboard.



I was looking at this one that @fenderman recommended.

Somehow I missed the equipment you listed, when I posted a few minutes ago.

Seeing the power usage of a HP Prodesk, I think you would get 5 - 7 minutes of runtime. If that's ok, then you can get the 850 VA / 510 W model.

You are confusing the power supply rating with power consumption. These modern systems use draw 7w at idle and 75w at full 100 percent cpu and gpu load

My mistake.

I looked at the rating for this Pro Desk, and it said 320 watts.

I don't know if this is the one @cam26 has, but I thought it might be close.

If the actual one @cam26 has is different, and uses what you said, then that's even better for runtime.

That is the power supply wattage, not the actual draw. No modern pc uses anywhere near 320w even at 100 percent load unless you have crazy dual cpu's and large graphics cards.
Every single one of these hp's draws about 75w at full load. The machines are not running at full load so likely 30-50w.

@nuraman00 that's the correct PC.

Thanks @fenderman. I tried looking at some charts and calculations but it's clearly just going right over my head. With that system and a Cyberpower 850VA/510W system, do you have an estimate on what the run time would be?

You would have to factor in everything connected to the ups battery side, including cameras and poe switch - dont connect the monitor to the switch. Cyberpower has a calculator on their site. Most fixed cams use about 2-5w or power. The switch another few watts.
I would get the apc unit just for the gigabit Ethernet connection alone unless you can confirm that the cyberpower has gig connections now.

This was suggested to me when I was looking at getting a UPS, last year, to get a Kill-A-Watt.

https://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU

You an also find it at some hardware stores.

I got it, and plugged everything that I was going to eventually plug into the UPS, into an extension strip, then plugged the extension strip into the Kill-A-Watt.

It gave me a reading of what the watts consumed were, and I was then able to get a good indication of what the run-time would be.

@fenderman's estimate of about 75 watts for the HP Pro Desk, + 2-5 Watts for each camera, + a few watts for the switch, is also probably a good estimate.

Do you also plan on connecting your modem and router?

Note the prodesk will likely operate at 30-50w max. 75w is with everything maxed out cpu and gpu, you cannot run the system stable like this. It requires head room.

What does this mean?



Do you mean for connecting it to the computer so you can use the powerchute software?

That should have read dont connect the monitor to the battery side of the UPS, it doesnt need to be on battery backup.
No i mean to protect surges over the ethernet.

Wouldn't plugging in the entire model do this? How does it look setup? I am probably missing something simple.
