is there any news about PICO's ? as i readed from yun9999's tread you was going to produce some bunch of PICO's and is this true ? if yes when they will be available for purchase. at this time i need 1 Deluxe 4K" Package and 4 PICO's...

GPU Packages now live! See thread here: https://bitcointalk.org/index.php?topic=1864539.0

Hey I've sent you two pm regarding "big momma" package.

PM'd back, thanks.

Hi Finksy. I sent a pm regarding breakout boards. Thanks

Sorry to ask this in your thread, but are these for sale in the EU too?

[Crs]

I would also want to know the answer to the question above.

Cheers!

I can ship to the EU, but shipping cables/PSU's is very heavy and VERY expensive from here in Canada.  People have had more success sourcing their own PSU's at least and purchasing the rest from me.  Keep trying to contact J4bberwock as well, he is based out of EU and this is his board design.

You got pm. Thanks

I got 2 "Deluxe 4K" Packages about a month ago and I love them. They were perfect for getting my over-powered APW3+s off of my S7-LNs and freeing them up for my newest batch of S9s.

Sent you a pm for an order, thanks!

I'm currently watching a 6-GPU rig pull 1090w at the wall (248v)... I'm looking to push this to an 8-GPU rig, and then replicate for a total of 3 mobos and 24 GPUs.  If I assume the non-GPU components take 150w per rig, that takes me to approximately 4250w (at the wall). I have external cooling available powered outside of this PSU, so assuming temperatures remain good.  (For example, my GPUs run at 60º +/- 3º all day long.

Do we think one of these DPS-4KW units will safely handle 4250w at the wall, continuously?

OP updated, PM's being replied to as quickly as I can.

DPS-2000BB PSU's are out of stock and unavailable to me at the moment, so PSU packages are only available without PSU's for this time.  I still have many IBM 2880W PSU's in stock, and can use them for GPU packages as well.

To answer your question, 4250W at the wall at a 90% efficiency is only 3825W DC, or 95.6% load.  It is heavy, but with sufficient cooling it can work.  Heavier loads can impact PSU longevity, but unfortunately with these PSU's there doesn't seem to be any consistency in what that load is and if/when they will fail.  I have seen many of these PSU's run at over 100% load for extended period of time with adequate cooling, and I have seen them fail under moderate loads for no reason.

Awesome, and thank you for that insight.  I saw your OP update about PSUs out of stock, and have sourced two separately in anticipation of your return.

Great, thanks for taking the initiative! PM'ing you back now BTW.

PM sent. Still trying to get a rig package bought. Thanks

How would you suggest wiring for one of these beasts at home?
