The SP10 uses a DS1050-3 power supply. However, I've found in the past that the DS1050-3 PSUs you can get on the market (e.g. ebay) do not work with the SP10, since there is some difference in how they supply 5V to the miner. The DS1200-3 used by the SP30 also works in the SP10. You can get those on ebay too, but the ebay ones also don't work in the SP10 because of the 5V issue. However, in the SP30, the 5V for the control board is shared between the top PSU and bottom PSU, and if either one correctly supplies 5V, then the machine works. As a result, what you can do (and what I've done in the past when we had a SP10 with a failed PSU, before we got spare PSUs from Spondoolies) is you can buy an ebay DS1200-3 PSU, stick it in an SP30, and then put the SP30's DS-1200-3 into the SP10.

Spondoolies will probably be able to send you a fresh PSU, though. You'll get better support if you email support@spondoolies-tech.com instead of posting in the forum.
