just found this pdu and grabbed 2 of them

http://www.ebay.com/itm/Genuine-HP-EO4501-Server-Power-Distribution-Module-228481-002/232449268221?

got this power cord

4 of them https://www.monoprice.com/product?p_id=24202

and will use 2 of these psu's for each pdu

How much power does a 741 *really* use? I have 245v at the wall, using the PSU above. When I have two 741s running off one PSU, the PSU sounds like a jet engine. When plugged into 3 of the 4 "cards" for two 741s, it sounds much better.

I've seen the 741 listed as using ~1150w, but I've also seen it say "+15%". Which is it? I have a killawatt, but it's the 110 version, so I can't measure the power usage.

Even if it's 1150w exactly, that's 2300w on a 2400w psu, which is pretty high imho. I'm thinking two PSUs for three 741s is a much better idea.

Thoughts anyone?

I have been doing videos on sound control.
I plan to demo 1 delta 2400 watt doing 2 avalon 741's
