Not long ago I bought a new old stock Turbo Cool 510w from PC power and cooling, the same model PSU used in the MaximumPC Dream machine in 2003.
This thing is something and I had to post it.

Despite being a fairly small PSU at 5.5" by 6" is weighs in at a smig under 5 and a half pounds.

Here are the voltages. 40amps on the 5v rail !

Here is a side shot of the PSU, note the copper heat sink. That is a first for even me. Never seen copper sinks in a PSU.

Peek a boo. Anther copper heat sink is down in there.

What are those blue things you ask? They are adjusters for the voltage 12v, 3.3v and 5v can be adjusted without even taking the PSU apart!

Whats this? A fan cable that can be unplugged without digging into the PSU ? That is rather nice.

Sadly getting a look deeper inside the PSU is no simple task given how jammed packed the PSU is.
Hopefully other will find this post useful or interesting.
