Title: [SOLD] 15.3Th/s Spondoolies SP20 with Power supplies.
Post by: padrino on January 20, 2015, 03:08:59 PM
SOLD I am shifting some of my mining operations around and have a package of SP20s with 3X 220V 80PLUS Platinum PSUs that can power it all...

I have been selling some singles in a separate thread and that has gone fairly well, I have dozens of SP20s in total, this is just another offering for some..

9X Spondoolies SP20s
3X IBM 2880W PSUs with breakout boards and PCIe cables (12X PCIe cables per PSU) - These are 80PLUS Platinum, they are the most efficient power supplies I have ever used.

I generally run my SP20s at 1.3Th/s each because I pay a hefty price for power but they have no issues running at 1.7Th/s..

Picture includes 4X PSUs with 3X SP20s each, I am offering 3 of the 4...

$4250 USD shipped to lower 48, international pay actual minus $100 USD. Will accept BTC or Paypal, if Paypal please pay fees and only ship to verified address on Paypal account.

About $400 per SP20 shipped, balance for PSUs.

Just to clarify, if you run sp20's at full speed you cannot use the H2880 to power 3x sp20's right?

(sp120) 1200X3 = 3600 watts
H2880 = 2880 watts
need at least another 720watts for full speed sp20.

That is incorrect, it works fine, but you are not totally off base, there are two factors at play..

1. The PSU is being pushed, however it actually will deliver upwards of 3600W but I am not taking it that high...
2. You are comparing the watts at the wall from Spondoolies with what the 2880W PSU is rated to deliver at 94% efficiency..  In short the SP20s are pulling between 950-1030W each, a total of right around 2900W.

match this price,(link below, 395 shipped) and I'll buy another one now. If you toss in another PSU, I'll do 450 (in BTC)

Thanks for the offer but with the PSU it would need to be a little higher since the shipping for both is rough.

Can you sell one of them without a PSU?

Still waiting to hear back from a couple of possible buyers but no firm commitments so currently still available.
