Server power consumption.

Hi

I'm sizing up a UPS for three boxes at home plus networking key. Rather than guessing what the figures for my FreeNAS server are, I brought a power meter to actuall check it.

My Dell T110i:

Intel CPU E3-1240 V2 @ 3.40GHz (8 cores)
16GB memory (thats all that I can afford)
6 x 4TB Iron Wolf disks
1 x 128GB SSD

My guess at first, based on zero experience, was 300W. It actually turned out to be

135W max load at startup
63W average usage.

I've no idea what everybody else uses, but if anybody needs an actual reading, here it is.

My Hackintosh runs 300W peak and 170W average.
My VMWare server runs 80W Max and 50W normally. Not bad for i4770 and 32GB Ram, All the disks in the VMWare SSD though.

Thanks

Rob

That sounds pretty normal - it's always surprising if you've been trained up on 600+W power supplies to run an Intel chip (90W TDP) and a fancy GFX card (250W TDP). My two NASes both report power draw in their own BMCs, the 8 disk runs about 110W and the 4 disk about 70W. My games PC (top-end i7/nVidia2080Ti/32gig/SSDs) maxes at about 280W, normally runs around 120W when gaming not stress-testing, or 40W idle.

Jamie,

Thanks for the reply. I was surprised at how little everything drew. The biggest surprise was my home built Mac, i4770, 32GB ram, dual 280X graphics cards, lots of SSD and 2-3 hard disks (I forget), I struggled to break 300W when doing multiple disk transfers, downloading, 4K rendering all at the same time. Not quote sure why I have a 1200W PSU now :)

Anyway, I can get the same UPS and get longer uptine so quite pleased.
