3Kw Power Supply?

Anyone know if these even exist? Setting up a mining rig, need around 2Kw of power draw continuous and obviously need some breathing room. I would prefer to have them all on a dedicated supply (not overly concerned with failover, price is my main factor).

Must be capable of supplying the ATX PCI-E standard connector. Any info greatly appreciated but please refrain from saying "Buy lots of smaller supplies" and the such unless you have some genuine info on why I should:)

I think people just use two 1500w. (well that is what I have seen from mining rigs on here)
 
I've seen one though not in the ATX form factor. It was a large square box. They'll be out there.

My main thought is that 3kW of power is a lot of hardware relying on a single and realistically very expensive power supply. I'm unfamiliar with mining but 2kW continuous strongly suggests an array of graphics cards.

Perhaps you could consider two computers, each containing half the graphics cards, and each run by a somewhat more conventional power supply. The main attraction would be half of the hardware surviving a power supply exploding. This does rely on mining being distributed, i.e. that it's possible to use more than one computer to work on the problem simultaneously.

This is using ASIC miners, unfortunately GPU mining went out the window a while back :(

3Kw was my largest target I could achieve as the site I will host the rig at only has residential circuits installed (It's not a house). I'll just have to lump it and go with getting multiple 1500's as "thrust4money" says :)
 
Are the ASIC's still pci-e based? If so splitting them into a couple of boxes may still work.

Though if you're paying for hosting it may be by the rack unit, making that rather worse value.
 
No idea if this 2000w is any good:

Why Settle for 1500W When You Can Get 2000W in a 20 cm Long PSU?

Chinese PSU OEM Great Wall unveiled a new 2,000-Watt power supply under its own channel brand (model: GW-EPS2000DA). Built in the 20 cm-long ATX form-factor, the PSU features a 90 - 265V input range, and is 80 Plus Gold-qualified (certification pending). It complies with EPS 2.92 standard, and supports low-power C-states on Core "Haswell" processors. Its maximum power output, however, depends on its input voltage. When plugged into 90 - 120VAC lines (US, Japan, Canada, etc.,) it caps out at 1600W. When plugged into 210 - 265VAC lines (EMEAI, Greater China, etc.,) it belts out its maximum 2000W.

Connectivity on this fully-modular PSU includes a 24-pin ATX, four (that's right, four) 8-pin EPS connectors (which can each be split to two 4-pin connectors); eight 6+2 pin PCIe connectors, nine 4-pin Molex, twelve SATA, and one 4-pin Berg connectors. The unit relies on a 140 mm temperature-controlled fan to keep cool. Great Wall is rolling out the unit in the Chinese market first, where it will command a staggering 3,998 RMB (US $654).

They are dedicated units but still require power from a PCI-E ATX PSU lead (2x to be precise).

Thanks for the lead much appreciated :)
