We have render servers that don't need to be on battery backup but we'd like to protect from power surges and being under-powered. I came across this power conditioner which will block surges and turn off power if it's being under-powered. http://www.newegg.com/Product/Product.aspx?Item=N82E16842101432

My only reservation is that it says it's for "AV" usage. I just want to make sure it's adequate to use with these servers that reach 2.67 Amps and 120.5 Volts at load.


Broadly speaking, all power conditioners do the same thing (run electricity through a buffering filter bank so what comes out is pretty and clean) - they're basically one stage of a UPS.
The APC (or any other quality brand) "Audio-Visual" power conditioners will work fine as a surge suppressor / line noise filter for computers.

That said, for only about twice the price of that power conditioner you can get a good UPS rated for nearly the same load, which will block surges, boost the line power if it's being underpowered, and give you a few minutes to power down your equipment if you lose power.

Given the choice I'd pay for the UPS: The first time you have a long render job that finishes on battery instead of having to start over when the power comes back on you'll be glad you did.

  • Thanks, that's the answer as I was looking for. As for the second part of your answer, I don't think it's feasible. There are about 50 nodes in the render farm and it would take a huge battery to power those things to finish even one render job. We also have limited space on the server rack. Just enough for 6 of these 1U conditioners. – Copy Run Start Mar 22 '13 at 18:39

    @CopyRunStart If your power loads are that high you may want to consider a datacenter grade (free-standing) UPS or power conditioner instead - 6 power conditioners (or UPS banks) can suck a good amount of power on their own, and generate heat. You'll get better efficiency if you can consolidate. If you can't consolidate you can certainly make do though. – voretaq7 Mar 22 '13 at 21:38
