Topic: [ANN] Selling Server PSU's with PCI-e cable (Read 4417 times)
3000W PSU received last week it was well packed. running 2 S7s no issues. great job with the cabling
So ordered the following:
Ran 2 S3+ @freq 250 for 4h: no issues
Will try tomorrow with 2 S5 @freq 350
Great packaging, PSU seems robust and cabling is well done and cables are long.

This list includes the efficiency standards for supermicro PSUs:

These server PSU's deliver 12.2 volt afaik.
If you calculate with 12.2 volt instead of 12.0 the efficiency is slightly higher (~1%).
I calculated it with the actual voltage, but since voltages differ across PSU's and load, I didn't post all those values If you calculate with 12.2 volt instead of 12.0 the efficiency is slightly higher (~1%).

Today I tested with up to 5x S1, here the results
We need a psu ~1500watt for last s7 batches.....
The power rating on a PSU is based on the output, not the input... So if 1500w goes in, only 1350 comes out (at 90%)
the 2980 or 2880 with the fan mod saves 40 watts
lot of photos on the fan mod.

It looks like a nice build, but I think it's going to be difficult to give a warranty on that :Slot of photos on the fan mod.

The 2880 is a silver psu.
The 2980 is a platinum psu.
They both use the same fans and the fans pull close to 60 watts.
In hardware section I did a fan mod to the 2980's and they give true platinum numbers.
I am on an iPad I will post link to the fan mod later.
As I type I am running five Avalon 6 miners using 4800 watts on a pair of modded 2980 psu's

In the end, you have a load which needs to be powered. It doesn't matter if you do that with a 2880w PSU or a bunch of 900w PSU's.
uhm that's quite wrong sorry ... it matters VERY much if you care about efficiency ... otherwise it's true yes
The efficiency is a curve which normally peaks around 60 to 75 % load of the PSU.
Outside that load the psu efficiency is WAY worse!!!
You can actually see it in your chart the efficiency for the large units climbed and it would climb further if you applied more load up to ~75% where it would slightly go down again.
So without a 2000watt+ load you wont find out the true efficiency of your 2880 watt unit.
I completely agree with you on the fact that efficiency is a function of the drawn wattage.
However: you can approach a situation from 2 vieuws:
- the PSU is most efficient at 70%, so I will seek a load that is 70%
- I have a load of X, how efficient is each PSU on that load.
I prefer the latter, that is why I will test all PSU's at the whole spectrum of loads.
with 6x S1 we will draw 2160w, enough to test all PSU's
In the end, you have a load which needs to be powered. It doesn't matter if you do that with a 2880w PSU or a bunch of 900w PSU's.

So without a 2000watt+ load you wont find out the true efficiency of your 2880 watt unit.
You can't compare the efficiency if you don't take the total wattage of the PSU into account.
If you test each unit at approximately 70% load then you can compare them.
1300 watt test @ ~ 900 load
2000 watt test @ ~1400 load
2880 watt test @ ~2000 load
I'm sorry to bother you that much but I do believe many customers would like to know anyway.
Moreover I thought MOST server PSUs delivery platinum or even titanium efficiency yet the numbers you provide are hardly even gold efficiency.
I heard of 94-96% efficiency server units, which are they?

This week I'll extend the measurements up to 6x S1.
I will add a 1100w ATX PSU to the test.
To be honest, I expected higher efficiency as well
If you have a suggestion, let me know so I can test them the same way... You can't compare the efficiency if you don't take the total wattage of the PSU into account.

Yesterday the new meter came in and I deliverd the first 25 PSU's.
The customer has some S7's (batch
and bitmaintech PSU's
2x Bitmaintech: 2672
3x 1300w+: 2792w
So the Bitmaintech is still 4% more efficient :s
Id did some extra measurements with the new powermeter
What I noticed about the 2880w power supply: As soon as the fans spin up, the usage increases about 30w (and that is already with 2x S1, not even full fan speed).

Wow, these 2000 watt units are appealing 
Running 2 units at 75% to 80% (1500 to 1600 watt) from one breaker seems ideal.
(at least for me, I have exactly one double cable = 2 plugs to each 240v/15a breaker, max 3600 watt)
At 75% they should normally run at PEAK efficiency as well.
Very nice page you have.
Thanks
Efficiency numbers for each unit would be great of course.
If you can eg. load test 60 % or up to 80% on each unit, that should be enough to provide useable numbers.
Moreover I never checked what protection features these units offer:
Some very crucial ones are:
1. SCP (short circuit protection = MOST important, can save your life
)
I'll check that with a cheaper PSU if you don't mind.
2. OVP (over voltage protection)
14V (Almost on every PSU it is 14v)
3. OCP or OPP (over current/power protection)
This one isn't that important with HUGE single rail PSUs which I assume they all are.
They're all singel rail. I'll test this again with a cheap PSU
4. OTP (over temp protection)
I know a 1400w PSU just quits at high temps
btw on your page I didn't find these 900 watt units you talked about ...
I've quit with those ones, since they're quite bulky and noisy

any news?
Just got them in. I will test it with 2, 2.5 and 3x S1
When running 3 PSU's on 2 miner
2x 103A = 206A
206/3 = 69A per PSU
69x12 = 828W per PSU
A S1 is about 350w --> 2.4 x S1 should be the same load
results: Tonight!
Unfortunately my power meter broke a couple of days ago.
When I test it with the Amp meter i get somewhere between 90 and 92% with 2,5 S1's attached....
I bought a new power meter, hopefully it arrives before the weekend...
BTW: I just finished my webshop: http://www.bitcoinpsu.eu/ I hope you gys like it

That price per unit is totally fine for me if the peak efficiency is as good as you say. (93-94%)
Actually I don't care about the single PSU wattage.
I just need about 2500+ watt at high efficiency for now. (maybe more in future)
The units can be as low as 900 watt or as high as 2880 watt ... I simply order that much units to fill my "wattage" needs.
(yes i know NOT to plug different psus to one and the same device
due to slight voltage difference of each unit/load)

I would like to order 2 units of the bitmaintech. (how many pci-e plugs?)
Are you doing escrow? and if, with whom?

Haha, unfortunately, I don't sell those (yet)
And still, before you have them here, you're looking at 145-160 euro per PSU without sales tax, so that efficiency comes at a price :S

I would take 2 units
But I would appreciate an efficiency test first.
(You can cut open the power cable "enclosure" and test the ac current-in that way.)

Ok, so first test results are in:
Summary
The bitmaintech is really efficient with around 93,9-93,5% efficiency on a S7 batch 8. The new 1300+w PSU that I’m working on reaches about 89,5%. I did not fully test a 2880 with j4bber board, but on first sight, it is even more inefficient.
Testing procedure
I’ve hooked both PSU up to a Batch 8 S7. Next to that I tested: 1-4x S1 on the 1300+, 4x S1 on the 1440 and 2880 with jabber board on 1x S7 Batch 8 & 1x S7 batch 7.
- All measuring has being done with a Voltcraft 4500 Advanced powermeter, a Voltcraft VC-330 powerclamp and a Tenma 72-7725
- Voltages were measured at PCI-e plug.
- Time intervals was 10 and 20 min.
Results S7 batch 8
Next to that I tested the efficiency with some antminer S1's as load.
- tested with 1/2/3/3,5/4 x S1 on full speed
The 1400 got around 88% and the J4bberwock with 2880 drew 2875w for a S7 Batch 8 and a S7 batch unknown.
If there is enough interest I will test more PSU's
And if you have measurement wishes, please let me know!

compare your 240volt ac amperage to your total 12v dc amperage.
The difference determines your efficiency.
Looking forward to seeing your "real life" numbers.
Unfortunately, I forgot a phenomena: "power factor"
So now I've got this baby: http://www.conrad.com/ce/en/product/1340670/VOLTCRAFT-4500PRO-DE-9999-hrs
This weekend I'm going to do some experiments with a Bitmaintech, 2880 and my new PSU.
I noticed just now that you have 1440 Watt PSUs in stock?
I would be interested in 2 of these 1440 Watt units, any details?
Shipment would be Europe, specifically Austria.
I would be interested in 2 of these 1440 Watt units, any details?
Shipment would be Europe, specifically Austria.
Normally I supply them with 8x PSU (10x PSU is +5 euro)
Depending on the temperature they will do between 1000w and 1400w
shipping for 2 is about 20 euro.
Will one 900W Dell PSU be able to run 2 Antminer S3+ miners?
If so will I still be able to overclock one miner since there are six 6-pin PCI-E cables coming with a single PSU. I will connect 4 of them with one miner that I want to overclock and I will run the other one normally with 2 of the remaining cables.
Also I noted that the shipping cost to India is nearly double of the miner = € 52,59
Can I get some discounted quote on this deal please?
I don't have the 900's anymore. I would advise a 1440w.If so will I still be able to overclock one miner since there are six 6-pin PCI-E cables coming with a single PSU.

One customers has them running at 20c and sometimes they fail... (dunno frequency/ precise temps)
I can make a version with 10 connectors, but I cannot guarantee it will be able to pull a S7 all by itself...
regards
Why do they fail? Cuz your customer tries to pull over 1300 watt??
It would also be nice a to see a efficiency curve because highest efficiency is usually only available at 50% load.
1300 watt not on stock anymore.
I'm working on a cheaper board for the 2880w IBM PSU as wel as a smaller PSU (1300w+)
At the moment I only have the 1440watts on stock.

Groetjes,
mav
One customers has them running at 20c and sometimes they fail... (dunno frequency/ precise temps)
I can make a version with 10 connectors, but I cannot guarantee it will be able to pull a S7 all by itself...
regards
no, that's why I swithed to a heavier PSU
Does these 1300w server psu's work well with S7 miners ? 
Why Bitcoin +1%?
I buy the PSU's & cables in euro.there are 2 reasons the price is +1%
- btc/eur rate is volatile, so it covers some of the risk
- conversion isn't free (usually a percentage of the amount)
Hoi!

I recently bought a set of 1440w power supplies for the increasing power need of the S7.
Unfortunately, the PSU's refuse to deliver more than 1200w for a longer period of time in a warm environment.
So I'm now selling them as 1000w power supplies. 1 can run 1,5 S5 | 2/3rd of S7 | 3/4th of a avalon.
Each PSU comes with 8x PCI-e, so you can easily connect 2x S7 on 3 PSU's
prices
1+: €55
3+: €50
10+ €45
EU shipping/escrow welcome

I'm looking for someone with an S7 to test how well the 1300w runs it.
I'll give a nice discount for a small review
(and if it doesn't work well I'll take the unit back, on my cost)

looks good to me too, also the 16awg is a good choice!
how is the noise with that fan?

I made a short video of the miner with a Monarch connected (400w)
The phone has noise anceling I think since there is more noise than you can hear in the video...
https://youtu.be/XE-TaWR3uQQ
I think noise level is around an S3, maybe slightly more. A lot lower than an S5 or the DPS-1200

Never mind I think I found them and they only run about 630W on 120v.
Jup, so not that usefull unfortunately...
Fixed
for me is fine the image!
how is the noise on this psus, i don’t see a fan!?
you may want to consider making the 1.3kw more compatible with s7.....
There is a fan in the back

It's quite large for a server PSU (that is the reason these are selected)
What do you mean? adding 2 PCI-e ports?
that is easier said than done unfortunately.
If you would wire it like this it should work fine
now the load of the 3 blades is equally distributed over the 4x 12AWG cables...

Are these strictly 220-240v or do they also run at 110-120v?
A picture could be nice, interested in seeing how your breakout board looks and what kind of Psu's are they ? Power-Rating..Gold, Platinum, ect.
and what kind of Psu's are they ? Power-Rating..Gold, Platinum, ect. Added an image, thanks
As far as I know server PSU's don't have these ratings.
Efficiencies are around 92-94% usually
Ok that's would be Platinum I think. Btw. nice work
