Now if you can find a way to fit it inside the box, it would be perfect.

Shoe horn maybe?  Grin

I'm working on a replacement PSU that will exactly fit the space of the stock one but will allow 1600w draw on 110v.
More info once I'll be back from holidays in 10 days.

please let me know as soon as that's for sale

Is EU seller for this PSU J4bberwock?  Huh

I'd say yes, since I'm the one making the boards  Grin

I'm still waiting on a reliable supplier for the case of the replacement PSU that will fit in the exact place of the stock PSU. The breakout board is done, and I have a few from the first test batch in stock.

Bump for Kexkey.  Also J4bberwock informed me he has a prototype completed for replacement PSU's that fit directly in the S4 chassis. I'll get him to post here as soon as he's finished!

Thank you for the info share with pictures.  EVGA 1600w can also do the trick and a few other 1500W or stronger PSU!

This PSU costs the same as an EVGA 1600W (or maybe less?), and can power 2x S4's, making it much more cost effective.  I would also hate to have to cut the pretty connectors off a brand new EVGA. Smiley



J4bber, let's keep this thread going.  When you're done with that board design and have a setup to fit, post it in here, or if you send me one for fitment I'll do the same.

evga 1600 g2 >> 305 usd  http://www.amazon.com/EVGA-Supernova-80Plus-Modular-120-G2-1600-X1/dp/B00MMLUIE8/ref=sr_1_1?ie=UTF8&qid=1429903880&sr=8-1&keywords=evga++1600+g2

all studs all cost over 300 usd.  what is your break out board + psu + wires?  much less correct?

but   of course you need 220 volt and you are loud.

So this is not a next to your tv miner.
Maybe more like an in your garage miner

Last night I wired up a harness to adapt the S4 to an IBM 2880W PSU with 10ga wiring and ring terminals.  Here are some pictures (Cables are a tangled mess, need to be cleaned up and wire tied in place):







The PSU's are rated to handle 2x S4's. Because I don't currently have a 2nd S4 to test with, I have 2x Asicminer Tubes running at 270 Mhz each connected as well, which should put at least as much load as a 2nd S4.  So far the PSU has no problem keeping up, nor should it.  I have tested the PSU's to around 2950W for weeks at a time without problem.  I will try to fit a 2nd S4 to run both off the IBM 2880W and show pictures.

Breakout boards for the IBM 2880W can be found in J4bberwock's thread for Europe/Asia/Worldwide: https://bitcointalksearch.org/topic/bladecenter-h-2880w-breakout-boards-selling-from-stock-limited-time-discount-893159
Or in my thread for Canada/USA:  https://bitcointalksearch.org/topic/ibm-2880w-psubreakout-boards-new-package-deals-for-t9s9-a7-966135

For cables I used 24" PCIe to PCIe cables cut in half and stripped, crimped butt connector and shrink-wrapped 10 ga wiring for both power and ground as well as a ring terminal.  If anyone wants to make up a similar harness, the measurements for the 10ga wire length are as follows (in addition to the 12" of PCIe cable with bare lead connected to the board)

12V+
21"
27"
22.25"
27.25"

12V-
21"
27.25"
23.25"
28"

Additional PCIe cable to power BBB board is approx. 36" to the breakout board.

Cables to power 2nd S4 (if stacked underneath) can be same length, but connected to the closer side of breakout board.
