Well, if they actually use these for servers then the quality has to be good :)

Ohhhh don't believe that, i work in datacenters and i saw so many shit cheap PSU's coming from china boasting nice specs, and being totally crap, but they wanted to save a bit of money, what a hassle it was, that's why im extremely prudent with such specs for this low price. Also those have been obviously modded to be used for mining so im being even more prudent. But maybe they're good, and if someone already got some that can share experience it would be great  8)

2400W HP server supplies are half the price, usually

Take a look at the Amazon UK Link, it clearly shows two HP 1200w Server PSUs NOT cheap chinese crap. Its the case im more interested it. Its just a housing to hold two common slot psu’s.

So whats different between those and this?  Should I stick to ones that clearly look like dual server supplies?

Sorry to be stupid, but just to be clear, with something like this, you plug it in, attach to mother board and graphics cards and it just runs?  No additional tweaking, soldering wires, tricking it to turn on etc?

Sounds like the main advantage over buying ordinary server supplies and tinkering with them all by yourself...hence the price difference

any news about this psu?

You can get 750W - 1200W HP server PSUs - which are built like the proverbial brick shithouse - for $25 - $50 all day long. Or better yet, get a PSU, breakout board and cables from Parallel Miner or the like and save money as well as aggravation.

And how would you advise to power mobo, cpu, ssd? PICO is one of the options, but it needs its own PSU as well...

No Pico PSU's only need a 6pin power socket on the breakout board of your server PSU to power it up. Look @ the picture on parallels miner you'll see.

For me the matter of this Kkmoon 2600w Dual Server PSU ATX enclosure is that it bring everything in one enclosure, is available for quite cheap, and i don't have to worry about shipping, $ > € conversion, customs import tax. Also most server psu's are pretty much out of stock everywhere... So i really hope it's going to be a good one !

But isn`t PICO AC-DC unit? It takes AC, converts it into DC which then goes into mb, ssd, cpu. Server PSU provides DC - how can it power PICO? I`m not understanding something here.

Yep, but its not a PICO issue, but with server PSU.


Problem:
i got 6 of the 180W version and 2 of the 160W version , and tried for 2 different mainboard with the 180W one

Asus B250 mining expert, the board cannot power up if there is 10 or more GPU connected ( of coz, GPU power by the X8 board itself )
so useless for this board

Biostar TB250-BTC Pro,
it is good, to use with 9 GPU ( again ,GPU power by X8 ) on this board , what a great product
however, it only stands for around an hour
the attached “12V PCIe cable power adapter” burned ( at the end which connect to the ATX module )
at first i think it may be because that cable has some problem,
so i change to use another one set , the “12V PCIe cable power adapter” burned again

now , i have 6 of 180W, 2 of 160W of this cable for nothing,
costed me USD362 before import tax and shipping for nothing
lucky at that moment i am around , otherwise, it cost much much more than that

so , conclusion is ,
use standard ATX power supply for the mainboard for your own safety ,
and leave the X8 for the GPU only

Hi Victor,

While troubleshooting for another customer who ordered the 180w adapter and our 2400w power supply kit we came to find that because the Delta 2400w power supply has an output voltage rating of 12.5v, vs 12v from standard power supplies that the Asus B250 motherboard bios settings will not allow the motherboard to boot properly if the voltage exceeds the max voltage threshold. So you are correct, for specifically the Asus B250 you would would want to use our power supply kit only for the GPUs.

As for the ATX adapter cable burning up after about an hour of use, we will need to look into this further to determine what the issue was. Please feel free to email me at Albert.s - at -centrix-intl.com or call me at 9094803000 ext 115 for more details. We can still set you up with a return for a full refund on the ATX adapters.

Thank you.

So better to use server supply that has straight 24 pin coming off of it rather than the Pico.  Still don't understand what they are saying below.  If server is putting off 12.5 volts and that is going into pico supply and pico supply is powering the board, then wouldn't it be the pico supply that is the problem?

Well, that`s brilliant then! No point using expensive branded PSU`s costing 400, server PSU +PICO is ideal combo.

By the way, there is similar product:

At first glance this PSU may look awesome but my primary worry about this kind of PSU is the build quality and power efficiency. Is it really 80+ platinum? I've seen some china made PSU with 80+ gold stickers which were obviously faked.

My next worry would be my power outlet / extension cord. Isn't running at more than 2000 watts in a single socket considered dangerous?

I am using this PSU with ASUS B250 Mining Expert MB. it works fine.

Hello,

Just got the PSU today in the mail, it was 160€, delivered by UPS (bought it on amazon, shipping was free), here is what i have to report so far.

- Clean build, pretty sturdy feeling/looking, well assembled.

- 2x 1200W HP power supply (model DPS-1200FB A / HSTNS-PD11), used of course but looking great and clean (i disassembled one, it look like new inside and outside, even "smell" new, wondering if it's not new but i doubt it), it's not a 2600W PSU, more like 2400W, the fans seems to have been replaced (not the brand you usually see in pictures)

- Disassembled the enclosure to see the connectors and PCB inside, look pretty great, soldering is clean and everything seems to be well built.

- 8x GPU cables built with 2x 12AWG cables departing from each PSU PCB for power load balancing, each GPU cables has 3x 6+2pins PCI-E power connectors each with 2x3 18AWG cables to each connectors coming from the 2x 12 AWG cables to spread out the power load.

- 24pin ATX cable + 8pin GPU cable on one 2x 12AWG power cable (again with the load splitted)

- 1x3 molex and 3x3 sata coming from 2x 12AWG power cable (again with the load splitted), splitted in 4 cables with 3x connectors on it.

- All the plastic connectors by themselves look OK, not the highest quality (pretty normal for this price range) but i saw alot worse. Should work !

Questions i have now

- Is the 18 AWG a good choice ? i think so because with the power equal sharing it should perform well. And that's what you see for most ATX PSU's.

- Why announce it as 2600W when it's clearly 2400W did i miss something, i doubt it, probably a mistake on their part. well 2400W is still plenty.

- Are the PSU's really platinium, since the model number i found is DPS-1200FB A and the model i saw on the internet are DPS-1200FB-1 A, i found a post here (https://bitcointalk.org/index.php?topic=1067170.0) saying that the -1 mean that it's a platinum PSU where as when you don't have the -1 there is no power efficiency certification. If someone got more information, i'll be interested.

I will come back with rig testings, feedbacks, and pictures over the week-end. Im in no way an electronic expert so giving out as much as i can with my limited knowledge.

I'm just very curious to see if its going to run the motherboard as all the pico issues seem to be from them passing the server 12V through the pico and the 12V from the server supply is like 12.5V so the motherboards won't start.  I'm sure the Chinese figured that out though.  They make a lot of junk but a lot of innovative things as well.

That's cool. Do you have some equipment (multimeter, oscilloscope) to feed us some data?

Multimeter yes, oscilloscope no (i wouldn't know how to use it anyway xD)

You can measure the 12VDC value and its ripple then :-)

As youve said its not too bad. It maybe a very good alternative to a dual psu setup and remove the need for the pico aswell.

Update us when its on a rig (and what rig its powering)  :)

any news on this?  Mine is arriving today.  Different seller but almost identical to this one.

Received mine today.  I didn't pull it apart like previous poster but I did pull out one of the supplies and it is the same supply as shown in the picture above.  I paid like 180 from Ebay. I hope the stupid thing works.  Still waiting for motherboard and cpu.

While server power supplies contained designate 1200W per unit (so 2400W total, not 2600W) at 200-240VAC, unit cannot handle more than 1700W full load on a 240VAC supply. I bought 3. 1 came damaged (bad packaging), but working. All 3 were tested. All 3 will be returned due to insufficient supply.

There's a recent feedback:

Please tell us how yours behave under heavy load.



In the meantime, has anyone tried their ATX power supply (https://www.amazon.com/KKmoon-Switching-Efficiency-Ethereum-180-260V/dp/B077JL5V3T/ref=pd_sbs_469_5?_encoding=UTF8&pd_rd_i=B077JL5V3T&pd_rd_r=8Z9RB01Y0GHE79P22XV1&pd_rd_w=3pNBk&pd_rd_wg=hKFub&psc=1&refRID=8Z9RB01Y0GHE79P22XV1)?

Hello guys,

Well at first glance this PSU was promising, but after a few days of testings here are the issues with it.

- Announced as 2600w psu but is only 2x1200 (2400w)
- Rated as platinium but it's obviously HP gold psu's (according to serial/model numbers) (i also compared the same system plugged on this psu, and on a normal platinium psu and the 2-3% difference are here)
- I didn't experienced it myself because i don't have a rig that can pull more than 1400W, but it was reported it can be bad to maintain power above 1800w, for a 2400w psu it's not really good.
- The overall electronic quality of the PCB isn't very good, the cabling is OK, but the rest is a kinda sloppy (for this kind of price it's not THAT bad per se)

Other than that my 1400w rig seems to have behaved properly with it. But again i was using it only @about 60% load, that's not really pushing it.

Conclusion : it's not THAT bad of a price and performance for a 1800w gold rated psu, there is plenty of connectors and such, but only for the fact they lied about the product (2600w platinium) im sending back my unit. So it's back to amazon for me sadly.

From googling it appears these are platinum supplies.  Doesn't really bother me either way as the power cost is not really that different.  1800 watt would be the top for 120V, is that what people are comparing?

Well maybe some are plat, the one i got weren't, so it's probably lottery.

Also i use 220v electrical outlets im in europe. But again i wasn't able to check this "limit" maybe it's BS.

After buying and running 22 of these... I can confirm....
THESE WONT HANDLE MORE THAN 1600W, FML.

Despite having 2x 1200W DPS 1200FB, it feels like they have fucked up with load balancing. Each one from different mfr has same issue. Now I need to find how to fix the issue or just throw away the breakout board assy and put normal breakout boards.

Any suggestions on that?

Honestly 1600Watts for under 200 on ebay isn't too bad.

Yeah, and a solo 1200 W HP PSU is $50-100, so...

Honestly 1600Watts for under 200 on ebay isn't too bad.
