This post by 73's de Edd deserves better publicity:
ASIDE . . . .Hear one and all . . . . .
On my computer power supplies, an initial task is to take the secondary filters and use two capacitors instead of the single ones. This done by stacking the second one vertically above the initial one with an insulative bakelite disc placed atop the primary cap and insulative polyolefin sleeving insulating for routing the side wires down to the bottom one . . .with microdots of E2000 adhesive assisting in wire dress and hold down.
A final test is logging in all of the filters AC ripple readings to reference against for future analysis.
UBER reliability experienced . . . . . the oldest case is a computer that is having 8 years of use and only a 2 and 5% ripple increase on the 3.3 and 5 supplies . Lo o o o o o ng way to go on that !
Thassssssit . . . .

Here is a photo of (I hope) a typical power supply. Please can you point out the cap that needs a mate
