picoPSU not working

[Klaymator14]

I have another question... Well, I had the picoPSU hooked up and everything earlier, but I didn't solder the wires into the PSU, I just stuck them in there. So now that it was working and the red light turned on, I decided to solder them, so I did. I did it directly to the pins under the plastic molding. But now, the red light doesn't turn on, only the green light. I was pretty sure it had to do with linking the PWR_ON and GND together, so I desoldered it, and just stuck it in the pins like before, but it still doesn't work.... anyone have any ideas? I don't know how I could possibly break something on the first day...

Can you get a few pictures?

Ok, here you go







Thanks Oh, and sorry for the huge pictures lol.

What a screw mess! Did you create that mess of damaged plastic and molten solder coming out of the connector, or is that the result of whatever happened to the PSU?
Anyway, as far as I can tell, the pins yu shorted on purpose were on the wrong side. So you shorted Ground and +5V. You have deserved a big fat

Hm... well I tried the other side... and fried it. Thanks... ordering another one...

Hmm? Did you remove the first bridge before doing that? If that fried it, it was because something else was shorted when you turned it on. I don't know... But the soldering job isn't exactly clean.

I removed the first bridge, followed your diagram and counted pins, plugged it in and it fried, I know my soldering wasn't exactly clean, but... it had a green light on beforehand, now it doesn't light up at all. But thanks for helping, I'll take much more care on the next one. Wish me luck!

For the future:
1) Use an iron with a clean tip to solder, and learn how to solder properly. (Seriously)
2) Don't bridge the ATX power on chip directly, instead use a 100-220 ohm resistor to avoid damage if you do it wrong. (And also because that's likely easier than trying to smudge a blob of solder between the two pads.)

...actually, for next time you might want to consider using an ATX extension cable that you chop off in the middle. That way you get easy access to the wires without worrying about soldering on the picoPSU. Plus the individual wires are colour coded to avoid confusion. Using the resistor for the power on pin is still a good idea though.

lol... I can solder pretty good, but I won't be so self confident in myself... I didn't really care if it would damage the plastic in the first place, because once I got it working, I would never really look at it again... So, I did get pretty careless. And when I tried soldering to the pads, the heat would distribute through the board and it would be hard to heat up the solder, that mess was a result of me trying to desolder it, but had trouble since I couldn't get it hot enough. Anyway, I will take your advice, and I appreciate your help! Thanks!
