How power hungry are these?

I have an earlier model, the 7050S. With a fan swap, at rest with no transceivers, 75W to 80W at the wall. It's a fantastic switch, just make sure you can find a firmware update for it... check the hash code on the Arista web site.

Is it OK to run these with only 1 PSU plugged in or will it cause all the fans to ramp up to full speed?

EDIT - Just did a comparison, 1PSU vs. 2PSU Both with no ports active

Switch 1 - Arista DCS-7050TX-64F
1 PSU = 165w
2 PSU = 177w

Switch 2 - Avaya ERS 4850GTS-PWR+
1 PSU = 83w
2 PSU = 104w

I also have another ERS 4850GTS-PWR+ that's powering 11 IP Cams plus all other ports in use and it no doubt is pulling much more juice. Can't take it down at present to hook up the power meter but according to the Lantronix metered PDU it's plugged into it's pulling 1.25a so 150w.

So the POE+ loaded switch is using less juice than the empty 10G switch.

Got an offer for 125, tempting but just concern about the actual noise.

The good thing about great deals is that if you are able to quickly try it out, usually someone else will buy it for the same price if you don't want it. :)

I joined the club this afternoon as my offer was accepted! Praying these things modded don't sound like a jet aircraft taking off =)

No, they do not. I have mine sitting on top of a Ayava POE+ switch and shutting it down there is no change in the sound level which means it's either quieter than the Avaya or about the same noise level. Granted it's not quiet but it's not objectionable either.

I recently bought a couple of Avaya 4850GTS-PWR+. They're excellent. Highly recommend.
