What's the worst brand of PSU?

Re: What's the worst brand of PSU?

well all my supplies last years - many years.
but i cant stand fan controllers.
a fan should move air - that's it's function.

i either remove the controller completely - like in FSP's where it's bolted to the heatsink, or bypass the output transistor on others like Antec.

so my caps run nice & cool.

I Don't like PSUs that have the fan running at full speed all the time. They're too noisy. A temperature controlled fan is nice as it still provides enough cooling to prevent the PSU from overheating, but it reduces the noise

you cant hear the psu on my machines,
it's drowned out by the 120mm jobs blowing over the harddrives.

I have a hercules 400 or 450 watt power supply in a computer that i built for my mom about 5 years ago. That was a cheap power supply

post a pic.
i had several of them in the shop where instead of a plastic sheet under the board they used the silver hercules labels.iirc the silver pigment is conductive!
these things were junk at best and dangerous imho.

But when you turn the computer off, the fan goes off but the 5vsb is still on - and generating heat.

i dont turn them off.
they run mule & torrent clients.

I agree. Not only that, but the fan also wears out pretty quickly at full speed (especially if it's sleeve bearing). Fan speed controllers are a great thing (of course only if they are made to run the fan at a proper speed).

Re: What's the worst brand of PSU?

sleeve fan's go in the bin with me, ball-bearings only.

Re: What's the worst brand of PSU?

The other problem with the fan at full speed all the time is that more airflow =more dust. I don't think sleeve bearing fans are that bad, as long as you oil them before they fail.

Re: What's the worst brand of PSU?

i dont have any dust,

i keep positive presure on all my pc's by using bigger input fans than exhaust fans.
the input fans have filters on them.

btw, if you want to reduce noise you should make sure your psu/case usins wire guuards and not "pepperpot" or some othe crap holes in the case.

i cut the metal out of some cases & psu's and fit wire-guards to reduce air resistance.

The Antec sucks canal water for sure, but the Bestec also takes the system board and drives to Hell with it when it dies.

Leadman/Powmax followed by Deer/L&C.

Re: What's the worst brand of PSU?

I vote for Besttec. I have personally work on 100's of emachines and the powersupply ends up killing the board. So you end up replacing the mobo + powersupply.
Like they say anything with the word BEST really never is.
