My first callback

[pentium]

Well last year I recapped a board for one of my friends and he has reported that ever since then the system has become more and more unstable.
He finally demanded I check it out again the other day and as soon as I got the cover off the case I had an idea where to check first.
He was using some Young Year PSU and my theory was correct when I opened the box. It was filled with Fuhjyyu caps and two were bulging and another two has vented. This voltages were also off (The 5V rail was almost seven volts!) and I didn't even want to think what his ripple was like.
I'm tossing the power supply (he loves to reuse stuff) and sending the system back to him with a note that he needs to find another PSU.

Re: My first callback

I'd just buy a good PSU, install it, and send the system back with a bill. Obviously he doesn't know how to pick a good one.

Those AcBel 550w units have been working well for me after P4 power connector modification. The price is right too.

Re: My first callback

put some idiot tax also.
did you check the psu under load? that 5v is high enough to make damages if it is so.

Re: My first callback

that one is a board killer.
wanna bet that helped kill the caps on the board?

Re: My first callback

btw thats not your callback.your work is ok.
i assume you did not install the psu!

Re: My first callback

Open the psu under his eyes and tell him the YY is a real shit; otherwise ask an high price for the repair.
It's criminal skimping on component quality, even if you're on a strict budget...

Re: My first callback

The PSU was salvaged from a dumpster ( ) and since I was the one who sold him the recapped board I know that is not the original PSU. I ran the board under a PSU I have and it's running stable (thank god) so I don't think it sustained any damage. He also knows what badcaps are (I was the one who informed him a year ago) but it's times like this where I still catch him slacking off on inspecting what he finds in the trash before using it.

Re: My first callback

You could of just recapped the YY PSU and sent it back to him. I recapped an L&C "450W" PSU for temporary use, and it ran for 5 months without problems which at 5 months I replaced it with a better PSU for making sure that system I had it in will last.

Re: My first callback

I did what Newbie2 did as well. I recapped a DEER PSU with bad caps on the +5V SB rail and it's now my test PSU which I use to test my motherboards for a short while. For a while it did power one of my main PCs but I replaced it with a Sparkle 235W PSU.

Re: My first callback

Good luck with those. When I find a L&C / Deer unit, it hits the garbage can. Do not pass go, do not collect $200.

Er, yeah me too. The strangest Deer I found was in a PC from the garage just up the road... Symptom was eventually 'no post', and when I went there the whole room stank of burning. The PSU's fan had seized and it had kind of quietly malfunctioned... this was on a Deer PSU from 2001! The PCB was brown and black in several areas, everything looked hot! But it hadn't done the usual 'blow up everything in the PC' thing! Like we used to get from those stupid PSUs in 2000-2002, where that certain capacitor had blown up and basically fried everything!

Re: My first callback

i guess they are improving their standards then

Re: My first callback

A lucky case it didn't blow up: Deers were and are cheap stuff. Did you try to recap it?
