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

[btarunr]

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).

why would anyone need 2000w...

 

[suraswami]

To feed the FX 9590 monster!

Yay finally FX 9590 met its match!

 

[Jstn7477]

why would anyone need 2000w...

To quad-SLi GTX 480s. Apparently two of them can shut down an 850w PSU with an LGA 1366 processor.

^Also FX-9590

 

[johnspack]

Yeah, I could use that! Only have 1650 watts now, but have to combine 2 psus to get it....

why would anyone need 2000w...

dual loop, triple pump waterloop, 5ghz fx8350 or equivalent/higher, 4x oc'd 7970s or equivalent, 5x drives, 12 fans or more, and peace of mind.

 

[Prima.Vera]

Yes, because electricity is so cheap nowadays that everybody can have now his own supercomputer home.

 

[Frick]

Oh you americans with your inferiour electricity. 1600W.. Hah!

 

[micropage7]

just pair it with intel atom based

I have a feeling this is going to explode in a review

Americans would just have to have a 240v outlet installed near the computer. This power supply can use 240v 60Hz which nearly every house in America has available.

Silly Asian manufacturers! If they knew anything about our power system here they'd include a 20A plug so we could actually use the thing...

But hey, what do i know?

Edit: We aren't all Americans over here. Some may find that a tad insulting to boot!

Great Wall is actually a decent PSU maker. Not top tier, but good enough.

The heat density on this thing must be astounding. I seriously wonder how this thing is kept cool at full load. Having owned a 1500W power supply, the fan was obnoxiously loud at over 1100W. I could imagine needing earplugs when this supply is fully loaded.

 

[qubit]

I can just see this destroying the TPU test rig!

crmaris, I challenge you to review this monster!

You know my post history, that was intended.

Anyway I don't know why people are saying it'll explode, Great Wall are capable of building solid things afaik. I want it reviewed ASAP in any case.

This 2000w PSU is for PC enthusiasts who are arc welders by day and PC enthusiasts by night...

You had better be plugging this into a 50 amp. wall outlet or you'll just pop the breaker constantly.

The UK 240V mains is rated for 3KW at the wall socket as standard, so here at least, you won't have that problem. Your electricity bills will sure go through the roof if you use it to full capacity all the time though...

 

[NeoXF]

I do remember LN2 enthusiasts using dual 1000W+ PSUs for their runs (tho I don't know why exactly, doesn't power usage drop under extremely low temperatures?)... maybe with such a PSU, they'd only need one...

Wrong. Most international 240v rails are two wire (a hot and a neutral,) plus a third wire for a ground. American 208-250v in almost every case is split-phase with two 120v lines that are 180 degrees out of sync. That way the RMS voltage between the two lines equals out to ~230-250v, but there is no neutral wire. Computer PSUs aren't designed to run off split-phase service, just single phase. A lot of appliances like electric stoves, driers, and air conditioners are designed to use this kind of service here in the US. It's more common to see 30a 120v service for needs like this in the US.

If the PSU is double insulated, would that not mitigate this issue?

 

[cdawall]

Topower put at a 2kw unit ages ago...

 

[Aquinus]

It's a matter of how the PSU is designed internally. The PSU expects neutral to be a constant 0v, but in split phase, it's always changing. It's the opposite of the other phase, as opposed to a steady 0v.

240v single phase service looks more like this, with the orange being the 0v neutral.

So even if the resultant output of split-phase looks a lot like that blue line on the bottom image, it's not working the same way to achieve that output. I don't think I would be willing to try it out.

Single 12V rail.
