Kkmoon 2600w Dual Server PSU ATX

[robl450]

Confused, if there are 2 1200 watt supplies, how could it only handle 1700W?

There's a recent feedback:

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.

Please tell us how yours behave under heavy load.



In the meantime, has anyone tried their ATX power supply?

...because their step down converter fucks is up?

I dunno.

didn't have much time yesterday, but I did plug the powersupply into the motherboard and it did post.  Honestly even if it does a fair amount less than the rated power, its still a good buy at least for the price I got it for on Ebay.  I assume too that worse comes to worse these could just be plugged into breakout boards with another small power supply doing the motherboard if you really need full power.

Looking at the pictures just now, I see the 24pin and CPU cable are being held together with exactly the same stretchy string as mine was.  I'd say if anyone goes with these they should probably get them on ebay.  99% sure they are the same supply for 80 dollars cheaper or so.

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.

I use similar ones. I only run it at around 1300W from the wall. The efficiency is about 94%. So it is quite good.

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?

[nitrobg]

If you are on 110V, those PSUs can handle up to 900W each. 1200W is for 220V only.

[jaykavathe]

Dont be a smart ass. Everyone knows about 110v/220V.
These PSU wont support more than 1600W even at 240V. I have a 400A 240V setup for my farm.

Yeah, I would try them with normal breakout boards. Maybe this helps indeed. Keep us posted if you see any improvements.

[robl450]

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

True that. But an item that is advertised as providing up to 2600w and cannot really do that is still a scammy move in my eyes.

[Amstellodamois]

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

Plus breakout boards plus cables .

[Amstellodamois]

I spent 109€ to get one PSU, one breakout board and 8 cables. Shipped.

When you setup your farm, connect 264 cards and then cant overclock anymore because of power issue, its a huge deal not to get the advt power.
Its so much of work to replace these on 22 rigs when every single card is stable and running (only at heavy undervolt though)
