OK Finsky.

BTW thanks for the PSU Works great now.

i got a question you or someone else might be able to answer, i got this nice IP Power Stitch with scripting and auto ping etc that i want to use to rereboot my miners when they become offline. of course i can't plug the IBMs PSU in them cause 1. the power is 240V and the switch is 110. and 2. even if could it`s only 15amp. BUT what if i plugged a small 12v Power adapter to power a relay switch that will be triggered to on when power applied to it, and connect that instead of the on off switch on the breaker board of the IBM PSU.

this way i could reboot all my miners remotely or un attented. but i got no idead of the parts i would need for the "relay" or if that even is the proper word for it. let me know what you think. or any one else.
time is a factor cause i`m going on vacation next week for 2 weeks.

heck this could be even applied to regular PSU bridging the green and black wire to power them on.

Fair approach given what you have, it should work.. In the case of the breakout boards, to the left of the switch they have two contacts, you can use those also to power on and off the board.. That should give you an easier option than playing with the switch itself..

Was any progress made with replacing the fans with something a little more quiet ?

I did see some posts that people were working on it but nothing conclusive as yet ?

cheers and apologies if im just being blind

I have also added packages to the first page to make ordering easier.  Shipping will still be calculated individually, and price breaks can be had on large orders ($2,000+).

First 16 boards of this batch have shipped out. Now filling an order of 90, then will have stock for orders. I am looking at about 1.5 weeks to finish this current order off, anyone who's interested in ordering can PM me, orders will ship out in the order they are paid for.

Still have not received the spacers, and tracking # is not updating.  I have re-ordered from another company with FedEx express shipping from the US, one of the packages should arrive shortly, and I will ship boards on the same day.  I apologize for the delay, and will have compensation for those that have pre-paid and had delayed shipments.

All my orders are handled by PM.  I will send you one with some information.

Still waiting on the board spacers to finish assembly, I think they hired someone to swim them across the ocean  Angry

Finksy, I'd like to order the 2880W breakout boards.  I've tried to PM but since I'm a nube, features are blocked.  How do I proceed?

UPDATE:

Finally, I have received most of the components and started soldering and assembling boards.  I am still missing many of the nylon spacers, but once they arrive I will have boards ready for shipment.  I have gone back through my PM's to notify anyone, if I missed anyone or anyone else is interested in a quote please PM me. I will be accepting orders, and they will ship out in the order they are paid for. I'll be producing around 40 per week, so it will still take some time to fill all the orders.  I hope to have all orders shipped out before the S7's ship.  Thank you everyone for your patience.

In my experience running 2 stacked PSU's was fine, so long as the hot end (break-out board side) isn't restricted on the bottom.  I.E. if you are running on a solid flat shelf/rack, the breakout board over-extends the edge to limit exhaust restriction.  Also, these PSU's come with a very good thermal shut-off, which I have had some PSU's hit on a nearly daily basis at certain times in the summer with lack of ventilation/AC. They come back online every time without a problem (50+ times), so running them hot IME is not a problem, they shut off before any major damage is typically done.  How hot you want to let the breakout boards get (in a multiple PSU-stacked configuration) on the other hand is another question, since the exhaust air can get to 100+ degrees.

That is great practical info! Thanks for the additional details.

In my case, I'm planning on reusing a beefy partial shelf that held a RAID array that we no longer use. It can handle at least 30 pounds, and is only about 14" deep, so two stacked 2880 PSUs will comfortably hang over the edge with the breakout board side in mid air without obstruction.

Sounds like this will work great. Thanks again for the useful details.

Kaltar, I am currently out of stock on boards, and am in the process of working with J4bberwock to shift some of the board production here to Canada to save on time, VAT and shipping expenses.  I'm looking at about a 2-3 week down-time, but when I am setup with the materials here on hand, I should be able to reduce the cost of the boards as well as keep more stock.  I will keep this thread updated!

I'm trying to figure out how I would deploy these in my rack, hopefully reusing some of the shelves.

Is it ok to stack two of these PSUs? Seems like that should be fine if the cases don't get very warm.

Which end is the hot end and which is the cold? If these were originally plugged into server cases with the fans on the front, then maybe the fans pull cold air in rather than exhaust warm air out.

I've run them stacked but stopped since the hot end was getting a bit too hot for my liking due to one side being restricted.

The cold end is the end with the fan pack.

Thanks for the info. It helps me plan. I don't have the PSUs in hand yet.

When you says that the hot end was too hot due to restriction, was that an air flow problem your particular installation? Or maybe you're referring to the breakout board restricting the exhaust?

In my case these would be at a data center, so the input air will be pretty cold (about 21 degrees C). So maybe I'll be OK stacking them. I can double check with an infrared thermometer.
