i am looking for a card for my pc, that has a 1 - 12 volt output. i know they exist, but where?

How much power / current does it need ?
And is it variable voltage or several fixed ones.

So Soundblaster cards used to come with a DC card that connected to the 12V on a HDD power cable and dropped it to 3/4.5/6/9 V but only at about 1/2 amp.

if i remember rightly ive seen something like what your lookin for in maplins ...im not to sure what type of card it is your lookin for but the one im on about fits into an empty pci slot and you plug in a 4 pin molex and the output is adjustable 1 to 12v 'I THINK" this would be to power the likes of external harddrives and so one ....not sure if this helps or is what your looking for ...if it is youll need to have a good psu ..the dc output is place on a rear pci plate "i think

"
it was maplins in blanch

AFAIK the LM317 also comes in a higher power version when attached to a proper heat sink can give several amps. - The LM317T listed only gets to 1.5A - and burns off the excess voltage so at 1V output you'd have 11Vx1.5A=16.5Watts of heat - so you would need something like one of the largest Pentium 1 Heat sinks with associated cooling fan (at a guess)
