Capacitors fell off

 Share

So I've got an old crappianware LGA 1366 motherboard, specifically the MS-7591 ver 1.0, and two capacitors came RIGHT off it when I was removing a graphics card. They're tiny little ones, located right next to the PCI-e x4 slot, my question is, are they needed to use the motherboard or are they JUST for the lower PCI-e slots? (see pictures). If not, I need some suggestions on a decent soldering iron. I want to save this motherboard cause its the only one I have for my x5650.

The only way you can really find out is by seeing if it boots. If it does, lucky break, it still works. If it doesn't, you might wanna get that soldering iron sorted out.

there's no easy way to solder a used capacitor as you don't have enough room to attach them.

its better to buy a new capacitor (they are cheap) with the whole leg still on, clean the motherboard hole.

from there you can just slide each leg to the hole in the capacitor and solder them from behind.

cut the rest of the leg and you're done.

These are surface mount I believe. If you have a soldering iron, you can probably heat it up and solder them back on.

These are indeed SMT.  Just get a 35w iron and blob them back on, they do not need to look great, they just need to be in circuit.

ok surface mount is a bit difficult, you really need a steady hand. if the leg still intact he's in luck.
