Advantage of generic PSU

[Badhon_raj]

So, I've experienced this first hand today.
it was my friend's pc.
at first there was this smell, then there was smoke and then the room filled with smoke..





disconnected power as soon as the smoke appeared but it was already too late.

all cble attached to the mobo was melted.
the sata cable and even the front panel audio header.

surprisingly 1 RAM and the HDD survived. even though the sata cable melted on mobo end.
I hope the processor can be re-used.

the psu is about 1 year old.

bad luck, bad Generic PSU

i had been running a Space 400w generic PSU for 6years, including 1year with a oced HD 4650, and a 2.5GHz E5200 at 3.2GHz

Space ar delux generic er moddhe bhalo.

Did you attach any power cable to the BIOS something pin?

or is it a fan header?

@redwan hasan amar mone hoi ulta ta hoise. I think He had a fault component which burned out the PSU.

Amar o tai mone hochhe ar PSU er pashe oita ki fan header kina ke jane emon hote pare 12V short out hoise and eishob PSU te over current protection thakar karon nai so eventually it will just die but before that if my memory serves me properly SMPS PSU jodi dekhe output voltage low hoye gese it will keep on increasing it's switching frequency to adopt to that but in that case short so voltage maybe close to zero te chole gesilo jai hok Intel er desktop board

really?
But the PC was running fine.
I've no idea. I thought the PSU caused it.

Everything always runs fine the day before ¤¤¤¤ happens
yah. After Seeing the picture its seems quite logical that that's what happened.

When PSU damages components the ports and connectors usually remains in good condition. the burned mosfets within components opens up the circuit.

This PSU obviously didn't have short-circuit or over current protection so when faulty component shorts out it stressed out the connectors 1st since that's the weakest point.

Nope.

It's sata connector.
or did you mean the the pins beside the 24 pin connector on mobo?
it's reset jumper.

then which component could have been faulty?
there was one casing fan, that is still running well, an HDD an ODD. nothing else.

oww I can see that the the place around the 24pin ATX power connector is the worst sufferer and as far as I can tell power circuitry is not there, those components are usually around the left/top side of the CPU and there might be a phase at the right side of the RAM for memory but usually located in a high enough place so don't know why only that place is affected like this.

Mm a diode mode diye MOSFET check korle bujha jabe which was the culprit. This takes time and patience and a bit knowldge about how a MOSFET is designed to work.

I don't have that. so will have to rest the case.

Yet, PSU is the most skimped part of pretty much everyone's builds.
