V880 Notes:

The Pinout for the v880's and v890's power supplies are the same with the minor difference of 15 instead of 25 Amps at the 48 Volt pin. (Which makes no big difference if you intend to power your Peprap Printer with it). But it is substantially cheaper, you can get a v880 psu for ~ 20 Euro from Ebay.
