Like the title says, what's the point of all the glue I see strung over EVERYTHING inside of most PSU's. Seems like the manufacturers go a little glue-happy at times!

Ludicrous gibs!

Re: why all the glue in PSU's?
My dad thinks so that loose components in power supplies will survive shipping without being knocked off. There are lots of glue around caps with some power supplies, and that drives me nuts.My gaming PC:

Re: why all the glue in PSU's?
The reson coils and caps are covered in glue is to eliminate the high-pitched tone they can otherwise create which is very annoying
It's common for older TV sets to have this problem; the glue has after the years gotten solid and thus does not prevent the multi kilohertz signal from causing for example the ferrite core in a coil to start moving and creating noise..."The one who says it cannot be done should never interrupt the one who is doing it."Comment

The Enermax EG301P-V 300W PSU I have lying around my house doesn't have any glue on the inside!

Re: why all the glue in PSU's?
I worked an assembly line job in a xerox plant, late 70's.
Next to me was the power supply line, 30 women, soldering, glueing and talking a mile a minute.
The glue was flyin around with the gossip.JimComment

Re: why all the glue in PSU's?
The glue is for mechanical stability, on lytics and on the toroid-core inductors. The switch frequency for modern switchers (late 70s onward) is above 20KHz, i.e. not audible (many current switchers operate above 100KHz).PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.
