Warnings well noted!!  BTW gents, a teenager in KS
was electrocuted recently.  He was "working" on a
computer power supply, UNPLUGGED from power
and apparently came in contact with a charged up
capacitor.  Killed him.  :(

At the risk of offending some on this list, be aware:

800 uf at 500 v can be a lethal combination! 200 uf at 2000 v is 
absolutely LETHAL - and you only get one mistake!

How do you intend switching this power? How will you generate the 
charging voltage (the charging voltage is also well into the lethal 
range!)? Safe enclosures, relay isolation, interlocks and grounding 
rods are required. It's not like transistor supply voltages. If you 
are not accustomed to this kind of voltage, please don't attempt it.

Sorry to rant, but I speak from 65 years of industrial experience, much 
of that with 1Kv+ operations .
