Please be aware!!! There is someone trying to impersonate me: https://bitcointalk.org/index.php?action=trust;u=769932

Please leave neg-rep and avoid.

PSU's & Package prices reduced, cost has gone down a bit.  May have a source for better-priced 24" PCIe cables which will bring costs down significantly.

You managed to turn the fancoolers without break board?

I can indicate that I tap pin to light source 2880

nice ill deff be in for some 6-20p cables , i have all my 277v circuts wired using 6-20's so nobody can accidently plug in stuff on those lines that doesnt belong there
as the poster above has said no more cutting up cords to put the right ends on

Nice!    I won't have to cut wires anymore.  Thanks!

how do i go about buying these psus

Replying to PM's, thank you everyone for your patience.

All PCIe cables and C19-C20 cables are back in stock.  I am working at obtaining some C19 to NEMA variations for a very reasonable price without too large a MOQ.  As soon as I can make it happen I will, PM me if you have preferences (NEMA 5-15P, 6-15P, 5-20P, 6-20P they are all built to handle the same amount of current, but have blades orientated differently to comply w/ code)

PM sent. No need of the C19, only board. I have spare Molex connectors if you dont have pcie cables in stock I'll do them myself. Thank you!

I will be away as of this Friday for a week, and likely unable to answer posts/PM's.  I won't be able to ship any more orders than what I have lined up by the end of the week.  I will resume taking orders when I return around February 1st.   Thanks,

Finksy

I am currently replying PM's (including yours), and apologize for the delay.

No packages available for sale right this moment, just waiting on more C19 and PCIe cables to arrive, looking at likely early next week.  Will post and update packages, thanks.

Any Royal With Cheese in stock?

Please note:  Pending some further testing by forum members, I have removed the 80+ platinum rating in the details.  The original post used to link to a data sheet on the 2880W that does not seem to be available anymore, and some reputable forum members have brought up concerns about the actual efficiency of these PSU's, especially our typical older revisions like the IBM PN 39y7351 and 39y7349 which were built before 80+ testing was available.  I'm hoping we can soon find out definitively where these PSU's fall as far as efficiency in comparison to other comparable 80+ units (namely the Platinum rated 2980W IBM PSU).  Also, note that the stock 3x fans used on the 2880W PSU are loud and consume quite a large amount of energy, up to 60W at full load due to the design with poor airflow through the case.  MarkAZ should soon have his solution finalized which consists of acrylic panels to replace the cover and fan pack on the 2880W PSU, with provisions to mount a single 120mm fan.  This should allow it to run quieter, use considerably less energy, and still maintain full output. I would like to thank Prelude for bringing this to everyone's attention. Our debate over the testing has been a bit heated, but I think he knows that I am not in this to deceive anybody and really do want to know the facts. I Will keep everyone updated, and thank you all for your business and support.  

Happy New Year!

Best not tell them i run 50A through several industrial grade outdoor cord extension for the 120V PSU, then. *Innocent smile*

I don't live in a House so i can't have an electrician come and move around circuits.

I don't see why these could not run off an oven outlet.  The only difference is that PSU's do not use a neutral cable (typically the white wire in a 2-hot, 1-ground, 1-neutral household appliance circuit).  Also, I definitely do not recommend running a big long extension cable across your house.  Not only is it against code, but it can be dangerous.  You would be better off having an electrician come in and move the circuit to where your miners are located, sorry.

Finksy

Either would be pretty nice. Is there a chance either of these can run on my oven outlet? I can't see anymore easily accessible way to get 240v. And then i'd need some long extension cord to bring the current to my living room window.

I never dealt with 240v before.

36" PCIe cables back in stock

Packages now available without PSU's

IBM 4K packages and boards now available!!!!  Link: https://bitcointalk.org/index.php?topic=1308296.new#new
