This just in from the United Kingdom: Three Badass water cooled power supplies from a decommissioned Cray supercomputer.
From the auction details:
Brown Applied Technology high power switched-mode PSU with PFC (Power Factor Correction). This power supply was developed for use in demanding computer applications where performance and reliability are of utmost importance.
Key characteristics of this PSU are the extremely fast load response and small voltage deviation. The unit is fitted with a water cooled base plate and a double-sided “spade” style output connection. It is possible to remove the base plate and replace with an air cooled heatsink.
Please note: Ex-equip, good condition. BUT some surface corrosion (mildew) from storage. Clean on the inside, it’s just the outer casing that is affected. Removed from a Cray super computer. Supplied with pin-out for front-panel control/interface connector. Tested, good working order, not DOA.
Applications could include:
High power laser diodes, Battery charging, Heating, Spot welding, electroplating.
If you need more than 3.3V, you can put two of them in series for up to 6.6V, or four for 13.2V !
