Default Salvaged Power Supply (100kb+ pictures)

A couple of weeks ago I caught a large Power supply at my work that was on its way to garbage. I realized by looking though the fan grill on the side that there were some fairly decent looking heatsinks inside. Here are a bunch of pictures before and after disassembly.

I'm obviously going to keep all of the heatsinks components inside as well as the capacitors but is there anything else inside such as the large toroidal devices that I should keep?

those heat sinks would make one nice amplifier. APC is one of the largest manufacturers of uninterruptible power supplies.

I attempted to calculate the dissipation specs on those sinks but couldn't quite get it.

Iíll post the exact measurements when I get home from work, but I would estimate them to measure roughly 3.5 inches wide, 7 inches in length, and 4 inches tall. The base plate is a little over 1/2 inch thick.

Maybe someone can help me calculate the specs.

I am gonna guess, using the thermalloy impedance tool, that with only nominal air movement (32 LMF) the C/W is about unity.

Is there anything else in the power supply that I should spend the time to desolder and keep?

The toroids and caps might be worth something. You can always use them later in a SMPS or high voltage project (well, the caps at least). Probably the relays as well.

Just be careful -- that stuff can still store a high voltage charge even after being unplugged.

I'd just shove the whole thing under your workbench, and just raid it for bits as you need them.
