I've got a videocard that had a capacitor knocked off of it. Is it possible to solder a new cap on in it's place? It is one of those caps that has a plastic base soldered to the board. The entire thing came off the board. How do you solder the plastic base without melting it?

Ludicrous gibs!

Re: Replacing surface-mount snap in caps
Marking on the caps is as follows-
450 (could also be 45q?)
180
16v
I would take this to be a 1800uf? or is it just a 180uf? I can't seem to find any suitable replacements at digikey.Ludicrous gibs!

Re: Replacing surface-mount snap in caps
Okay, just saw it's a solid polymer. Which means that it's probably 180uf 16v. Here's what I found from UCC

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:

My 3.5 years old monitor (BenQ SW2700pt) started to black out for 1-2 sec every minute or so, it was doing this even with PC disconnected from it. I searched online and read that it's probably aging capacitors and there's a workaround to lower the brightness.
I lowered it from 100 to 65% and it indeed helped, but after a couple of months the issue returned... I continued to lower the brightness, but it helped only for a couple of hours at most, then I needed to lower it further... Turning the monitor off and waiting for it to cool down also helped for a short time, after which it... -
Hi
Recently I got this tagan tg380-u01 PSU with bad caps on 3.3v rail (the line was 2.5v no load!). Replaced them but no go, so I've replaced all of them, apart from some smaller ones and one under the secondary heatsink. Even that didn't help so I've replaced the others. All caps are known good ones.
Powered it on and heard the breaker pop. Opened it up and saw some smaller caps shorted together. Fixed that up but still it trips breakers. Now I get 0ohms from 5v to GND. Secondary heatsink removed and still a short, even with the PWM IC board removed. All diodes on that... -
nichiconare what i used because i had heard the voltage doesn't matter as long as it is more than the original cap. i'm now reading that high voltage may make the cap's esr too high. is this a good cap for replacing those oem ones?1500 µF 16 V Aluminum - Polymer Capacitors Radial, Can 8mOhm 2000 Hrs @ 105°C -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
