Safe to remove lid from PSU?

What the hell? I've never heard of adjusting power supplies like this before.

That's the Internet for you. Strangers telling other strangers to risk their lives for something that ain't worth risking lives.

Not going to do it so no worries. Reminds me the story about the guy that got killed using his iphone in the bathtub still attached to the charger. Nuts.

As you asking such question then no.

The big choke coil on the left looks melted. Pic looks detailed, am I imagining that?

To me it looks that that's done to stop that noise that so many complain about

if you are an adult and feel confident then go for it. Looks like a really easy adjustment.

Actually I would go for it if not for the fact my cable management work took hours to get right. Think I'll do it one sunday i got nothing better to do. Thing is i'm sure its an easy task, but for powering it up topless to check the rail adjustment kind of scares me. I suppose i could make my adjustment and close it up then test. Thanks.

What you asked: NO.
I routinely take 'em apart, noisey fan, no output etc. (<-mainly these 2 reasons) If junking (for fan?), I use either a wire brush or steel wool wiped across prn circuit board to discharge those caps, they can hurt!! They can kill. Usually, there is a fuse generally soldered on the board, when it is 'blown', the psu is junk. I have replaced/jumped across it & found when it goes, something else goes too. ie: its junk.

BE CAREFUL

Hi,

Got a Pc Power Cooling Turbo-Cool 1200 that has a 3.3v rail being read by hwinfo and other utilities at 2.98v. Read that the 3.3v rail is adjustable but the dial is inside the psu. Guys think its safe to remove the case and make an adjustment?

Thank you.

There is a percent variance of what is acceptable and what is not on each rail +-. Opening a PSU does void warranty. Opening a unit that has been previously used does store energy in the capacitors which can result in injury or flatline of the heart, so it is not advisable to go poking and prying in a psu unless if you know what you are doing. You have been cautioned.

Well I don't want to wind up dead so not going to do it..

Software doesn't give true readings anyway, might invest in a Multi-meter if you want to learn or read the rail properly.

I have a good voltmeter but unsure what wires to test.
