I recently came across the 'HIPER TypeR' modular psu, which has detachable cables which i think its a rly usefull idea. As these are now discontinued and all the other modular ones look kinda crap i thought id make my own seeing as i have about 5 PSU's sitting around doing nothing.

The only problem i have, is doing anything inside the psu itself. I realise that the 2 large capacitors hold 110v each and touching them or any part of the circuit connected to them can result in a lethal discharge and possible death :eek:

Is there anything i can do to avoid death, by discharging them or just taking steps to avoid them? As i can do most of the wiring for everything else fine, i just dont want to end up touching them.

Thanks in advanced :p

If the power supplies haven't been used in a computer for awhile the capacitors inside them will be discharged and you don't really have to worry about getting shocked by them.

If they have been used in computers recently, just unplug them from the wall outlet and let them sit for 24 hours to give the capacitors time to discharge.

Is there anyway i can test if they are still charged? Other than trying my luck at touching them :D
i have a voltmeter here would that help?

Capacitors don't hold a charge indefinitely but the larger ones do take longer to discharge. If the power supplies have not been used in awhile there's no way the capacitors will have a charge in them. But you can use a voltmeter if you have one to be sure they're discharged.

Plug a molex into a hard drive too maybe?

You can take a 10K resistor and a length of wire and short the two leads together with the resistor between. The 10K resistor will slow the discharge enough to avoid snaps and pops....

Check the voltage across the terminals and if it's less than 20vdc, I wouldn't be concerned.
