I present to you the APC AP9571 The "smaller" cables are 14awg and 2feet long for reference. The 6-30P end will come in handy the next time the old lady gets out of line Special thanks to DAT.

240v power distribution.
208v power distribution. (three phase) I suppose there isn't much stopping someone from using 240 with it though? I don't see any meters or switches on it -- just a bare PDU.

So, what function does this thing serve? It looks like a big powerstrip, where I know it does something beyond that...

Nominal input voltage 208 V Acceptable input voltage ± 10% Nominal input voltage 228.8v power distribution So, what function does this thing serve?

Allows psu's to be run at 240v for better efficiency.

So it steps up 120 volts from the wall to 240?

Nope, it's basically a 240v power strip.

Nope, it's basically a 240v power strip. Shoot. I knew I missed something. I was thinking, stepping up the voltage is just going to generate heat that you would lose from 120v inefficiencies, so why bother? Makes sense now.

so question remains: what the hell does it do besides be an expensive power strip?

Lets you pull nearly 6KW from the wall without a) causing a fire b) tripping breakers c) wasting 3% to 5% due to lower 120V inefficiencies It also comes with a nice locking plug, and a heavy duty cable for nice solid power distribution. If you have one or two rigs it serves no purpose. Once you pass the 10GH/s mark you start to realize power & cooling are your limitations. 30 amps @ 240V keeps a lot of miners mining. I got two.

SlaveInDebt ignore the "haters" . I guess you got to be an engineer to love high current, high voltage power distribution. The APC AP9571 is solid. I was pulling nearly 5KW through one and the cable didn't even get warm. Your significant others will enjoy not having to play "power switch roulette" and then yelling "$@### miners" when the breakers trip. Just wire it up right. 30A SPDT breaker, 10-2 ROMEX wire, dedicated electrical box, NEMA L6-30R outlet.

DAT speaks the truth. I was maxed out of 120v at my main mining cave and even running extension cords to use 120v pulling 1200w from them and they get warm to say the least. This strip screams quality and strength .If you don't feel more empowered wielding the 12 foot cable with massive plug on the end then you must already be well endowed. Had a 240v right next to the rigs all along and figure why not as you've said more efficient and safer. The line is already 10 awg so I'll be swapping out the 20 amp breaker and outlet tomorrow to 30amp. It will allow me ~6 rigs the one strip and leave me up to 6 more rigs on 120v in time, though I'm more likely to just run another 240v line since this is a basement and the breaker box is only 20 feet away

First one 30A @ 240V circuit and then a second. Too bad nobody makes a 50A PDU. Cause no way I am using all 12 plugs with "only" 5.7KW usable power.
