IBM 2880W PSU/Breakout Boards - *NEW* Package deals for T9/S9 & A7

[gt_addict]

This might be a stupid question. It how quiet are these? I'm looking for a cheaper alternative to atx psus for my home mine. Trouble is it's currently located under my desk.

Not a stupid question at all.  The answer:  Stupid loud 

I do not suggest using this for an under-desk PSU.  It is on the edge of being unfeasible for use even in a basement/garage depending on your tolerance.  If you need that much power, you could go with the DPS-4K (another PSU board/packages I sell in my sig), it can be made as quiet as you like by choosing the 120mm fans for cooling. However if you are just replacing a ~1000W ATX PSU, you would be better suited with something like a DPS-1200 with breakout board.

Funnily enough I forgot I posted on this thread and ive posted on your other one asking something along the same lines as you've suggested 

[Finksy]

Bump.  Stand-alone ATX-replacement GPU packages coming in short order! Stay tuned...

[Finksy]

Bump for Bitmain's new T9.  I would recommend the Double A Package upgraded to the 2980W Platinum PSU.  Increased efficiency to help offset the efficiency on the T9, and 2980W to give a little bit of breathing room.

As before, I will offer free upgrades to IBM 2980W Platinum PSU's on the next 10 Double A packages purchased and will extend PSU warranty for 3 months, as I am confident they will power the T9's reliably. The 2980W Platinum PSU packages will be shipping from here in Canada.

[TunerDude007]

Do you have any 110v options? I'm in Toronto myself, where exactly in Canada are you located?

[Finksy]

Sorry, nothing in 110V.  Both the DPS-4K and IBM 2880W require 200+V, sorry!  I'm in Northern Ontario, about 4 hours north of Toronto.

[Finksy]

OP updated to reflect lower PSU prices again! 

[Finksy]

Away on Holidays from now until March 3rd! Trying to get everything shipped out before then. Will try to keep in touch, thank you for your patience.

[Finksy]

Bump this up, packages shipping out daily. Still have a few platinum 2980W PSU's in stock!  Keep your eyes peeled for GPU-focused packages coming in the next 2 weeks.  2980W Platinum server PSU could power up to 3 full 6-GPU rigs without requiring ATX PSU's!

Hi Finsky,

i'm still waitung for your reply on my PM, thx

Enough to power 2x Antminer S9's for as cheap as possible
 - 1x 2880W PSU
 - 1x Breakout board
 - 20x 24" PCIe cables
 - 1x C19 power cable of choice (see below for stock)
Order components without PSU for $115
Upgrade to IBM 2980W Platinum PSU for an additional $30  
Note: I would recommend the 2980W Platinum PSU packages to power 2x of the new Antminer T9's, but these will still be at 97% load.

Do someone know if the 2880w PSU can really power 2x S9 on the long term ?
I made a test, and this is 3200w at the wall for two recent S9s.
The PSU seem able to handle it (Server PSUs are strong) but will it last long like that

Yes, they can really power 2x S9's long term.  3200W at the wall is exactly 2880W DC power consumption at 90% efficiency (since these would be considered max load).  I have hundreds of them powering S9's in Data centres for months now without problem at this level. My failure rate is ~1%, most of which is DOA's.

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

[Finksy]

Bumping this up.  4K PSU's are not currently available until supply of DPS-2000BB PSU's are reliably available again.  Take advantage of the beast IBM 2880W-ers!  For GPU rigs, these can power up to 3x rigs with 6-GPU's per rig (or 2x rigs with up to 9x GPU's per rig).

How loud are these things?

STUPID LOUD!!

[Finksy]

Like having chalk tied to a fan spinning at 6000RPM against a chalk board. They are slightly louder than S7/S9's, but higher pitched.

I have one running in my garage. Helps me sleep at night. And no, I don't sleep in the garage
