I have personally taken the PSU's up to 13.4 amps (3200 watts) With 3x SP20's for a span of two weeks or so. Held up just fine, I imagine soab's run up to 3785 W was fairly temporary, I feel like the thermal cutoff would have kicked in if run for extended periods of time.

Hi:

Is it possible to solder the cables directly to this kind of PSU with out the need for breakout board like other lower server PSU ?

thank you.
Here are some pics of how we made the harness. My buddy owns a cable manufacturing company and even using $120,000 of equipment, the time and effort was not worth it. I only made these because of the delivery time to get J4bberwock boards for the first 52 Antminer S5's. I highly recommend not even consider doing harnesses and just buy the boards.

The equipment we used  to do this project was an auto feed wire cutting and stripping machine that did all the 10 gauge black and reds. Then we used  an automatic stripping machine to get .6" on the pre-made PCIE wires we got from klondike_bar. An ultrasonic welder was use to join the wires. Had to use a 150 watt soldering iron to join the welded pads to the power supply.

There is also a shot of the power meter when the room was hot and the fans were at max, it was drawing 3785 watts.








I put in bold letters the advice from the only guy that did it to my knowledge.

Thank you J4bberwock for good advice , i know there will be a lot of work involved to harness the connector.

 but what it take my attention is this line:

Is the high watts drawing by the PSU is a result for the harness connection?

If yes, what the power drawing when we use your breakout board on full load?

Thank you.

Get your supplies wired up in time for Sfards or the Antminer S7 release, coming this summer!  Currently working on getting 24" cables for cheaper.

Have everything ready to go, shipping will take up to 48 hours right now due to work constraints IRL.

Replied.

I'm out of town until Monday, so communication is a bit spotty. Have more packages arriving from J4bber on Monday-Tuesday, and will have everything in stock.

for a psu the breaking board is used to connect the psu and replace a computer motherboard? is that for that purpose? have connected a psu to a computer motherboard to switch it on...
mining giving less than electricity bill
IS there a way to reduce electricity bill of a psu ? can breaking boards be purchased anywhere on the web and plugged in to a psu? Does it give better efficiency for costs?
How many antminers S3 can be plugged to your psu? What costs does it give for monthly consumption : how many kwh each month for one S3?
Can you sell a breaking board and ship it to mauritius? can it be plugged to a thermaltake 360 W psu for board connection?
Thanks to reply

Holy Crap Buddy, do a bit a research before asking all these irrelevant questions.

These Breaker Board are only for this PSU, look at the pictures at the begginning of this post.

reduce electricity, get a better rated PSU, GOLD or above.

Use the paper clip trick to power on the PSU, no need to plug a motherboard in it.

different breakerboards for different SERVER PSU can be purchased from other peoples.

How Many Watts per hours. go look in the S3 Threads.

How Many S3 for this PSU, do some maths. 2880 / 330

but don't expect to just plug this PSU in your outlet, you need 240V

He posted the same thing in my thread, I get the feeling that English isn't his first language and he's never seen supplies like these before.

Yes, these run on 240V SINGLE PHASE power (also referred to as split phase, 2x 120V hots + 1 ground as is typical in North America). I have not tried these on 3-phase 208V power, though the label does not specify, it only states 200-240 V 50/60hz.

I was about to buy one of these but want to confirm here whether these will run on American 240v (which is +120v hot, -120v hot, and ground). Most modern psu can take almost anything but since this is a dedicated server 240 psu I just want to confirm it does not require a +240v hot, neutral, and ground connection.

Do you have a C19 to C13 adapter for these? Or a C19 to 240V outlet cable?

I only have C19-C20 cables.  I don't recommend using C13 adapters, as I don't believe the C13 receptacles themselves are even rated to run at the required AC current in steady state (14 or more amps).  As mentioned in PM, what I do for wiring up individual PSU's is to cut the C20 end off, and wire on a replaceable 20A 240v 6-20 NEMA plug:

and use the appropriate receptacle/wiring. For multiple PSU's, wire large individual 50A power circuits for a PDU, and connect each PSU/breakout board to the PDU.

Can take orders for PSU's with 36" cables again.  They are scheduled to arrive early-mid next week.

If anyone who has purchased from me is willing to, I would greatly appreciate trust being left.  I have had quite a few successful sales, and like to think that I provide good service to my customers.  Any problems are dealt with accordingly, and I would like to build some positive trust to prevent any wrong-doers from dragging it down.  Thanks,

Finksy

Trust left. Smiley Sorry I forgot to leave it when I should have!

Side note, might need some more hardware soon. Will drop you a line!

Finksy will have something for you in the batch he'll receive on wednesday, so it might be a perfect timing.
