Finksy, pm'd you

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.

[Finksy]

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

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.

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.

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:

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.

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.

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.

Will this break out board work for the IBM 39Y7408 Bladecenter H 2900W as well? Or is it limited only to the 39Y7349 Model?

it works for any bladecenter H PSU.
BTW, some sellers are rounding the 2880w to 2900w, your P/N 39Y7408 gives 2880w for me.
