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

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

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,

Many PSU's shipped out today.  Thanks everyone for your patience on getting more of these in, still plenty left.  After pricing some units drop-shipped to a US customer, I'm afraid next time I order these there may be another price increase Keep your eyes on e-bay for cheapies!

P.S. will have more 36" cables shipped by the end of the week, should have them mid-late next week.

Alright, PSU's arrived today. I'll be sending PM's out right after this, and prices have been updated on the first page. I'm afraid the next batch of PSU's will likely continue to increase in price, as it seems the used PSU market is not infinite.  I have had all my 36" cables reserved, but will have more as soon as I can get some from J4bberwock.  Thank you everyone for your patience.

P.S. If I missed anyone with a PM who were interested before, sorry please PM me again.

Woot, don't forget to put 2 aside for me

For anyone needing large orders in the US (5 or more), I can have PSU's drop-shipped to them as well to save quite a bit on shipping, I just won't be able to test them ahead of time.

How many did you order?

Good news, PSU's have FINALLY shipped today, hope to see them shortly.  What a cluster-fuck that was...  All I can say is supply of these PSU's is getting lower, we are somewhat drying up the used PSU supply for North America. Go miners!

Not exactly, you were pretty close at the end there. It's a pretty misunderstood topic, and since most things outside a few very specific niches just "handle" any voltage difference it's rare that anybody nowadays needs to know. But, for the record, in the US at least the homes are supplied with a single 240VAC feed which is "split phase" meaning it exists between two phases or "waves" of AC current, one is -120VAC and the other is +120VAC. These  are in fact split in to two legs when they're fed from the mains in to your breaker box, you can see evidence if you ever take the cover off your box and notice each breaker alternates feed lines. Anyway, without falling down too much of a rabbit whole (sorry AC is a bit out of my wheel house, I much prefer low voltage DC) the 240VAC line that is available in all american homes (I believe it's required by law? or mandate? Hell I have no idea) rests in between two 120VAC waves. This is often referred to as dual phase 240V power.

So it stands to reason that you could win an easy bar-bet by asking the simple question "what voltage does the electric company provide to your home in the US". My assumption until it was explained to me by someone far more intelligent was 120 volts is 120 volts, none of this voodoo wave crap.


So 440V? Or do you mean split phase 220V? Not to be confusing but I do know some of my customers have in Mexico and elsewhere have a single feed of 440 at there factories or industrial areas, or at the very least it's the only reliable power source. If you mean 2 phases of 110V then yes this will work with split-phase 220V. It's confusing, it's convoluted, I feel like I'm pretty spot-on in guessing you mean dual phase 220, or split-phase, and not two separate phases... if you do mean two seperate phases then it's an easy fix, I believe you can just disconnect one of the wires, but don't quote me on that and I almost regret saying that already!

As far as I'm aware, Two-phase power is not in popular existence anymore.  If you are referring to standard single phase (using 2x 120V legs off a breaker panel to get your 240V) then yes, that is what is required for these.

As far as three-phase power, I am not 100% sure whether these (or any popular server or ATX PSU's) are designed to operate on typical 208V 3-phase power.  PhillipMA had created a thread about using 3-phase power with a PSU, and I believe he was planning on using 2 out of the 3 hots along with a ground to create a compatible Single-phase power solution, but I do not know where he is at in his testing.  I have a customer who is planning on using these PSU's with 3-phase power in Ontario, but again I cannot confirm whether or not these will work directly with standard 3-phase power.

As for my PSU stock, they should be shipping tomorrow, and I will be picking them up within the next week (hopefully), but I still do not have confirmation on dates.  Will update as soon as I know for certain.

Hi!

Does this PSU works at 220Volt in 2 phases?

Still no PSU yet. ?

PM'd

i would like to buy 2 breakout boards and 16 of the 24" cables
can you pm me with a price
thanks

Just a heads up, I will be away until next Wednesday, and likely will not be able to answer messages.  If I can I will PM everyone back as soon as possible. 

Will update when PSU's arrive.

Here is a thread on adapting IBM 2880W breakout boards to replace PSU's in 2x Antminer S4's: https://bitcointalksearch.org/topic/s4-psu-replacement-alternative-1036295

If I get some time, I will make up some harnesses to sell myself.  I'm a little busy for the next week or more, so if anyone wants to do it themselves, all the measurements are there.

Noooooooooooooooooo, i was waiting for the c19 cable and now no psu.
when you receive the PSU's i'll order one right away.

thanks

I bought 3 boards, will make a review when I get it.


 

Update:  I am currently out of PSU's.  If anyone would like to order boards, cables, etc and source their own PSU's, PM me.  I have more on order, and will update the post as soon as they arrive.

I will be in the GTA this weekend (leaving tonight), if anyone in the area needs PSU's, boards, cables or anything of the like, let me know and I can bring them when I leave this evening.
