Rampage Extreme 775 expanding capacitors?

Hey everyone, have had rock solid stability out of this old original ROG board, but it recently developed problems with the audio and a wireless mouse.

The audio card is an Auzentech Bravura in the lower PCIE slot, and I noticed that one of the capacitors below the PCIE connector looked like it had exploded. Pushing on it slightly, I noticed the can moves very easily, and it does appear expanded and damaged but I got the audio back!

What cap is on this board if the numbers on the end of the can are:

5K
88AK
271
16

Would this be a 270uf @ 16v capacitor? What would be a decent replacement? I see some caps on fleabay that are 270uf @ 16v, but is there a specific type/brand to look for or better yet, to stay away from?

Thanks!

If you identify the capacitor value properly, then replace it with any genuine branded capacitor manufacturer like panasonic, nichicon, samwha, etc. While replacing the capacitor try to wear wrist antistatic belt. Check whether any other components or parts are damaged?
If the Board is under warranty, service it with manufacturer.

Capacitors are usually marked in pF. 271 would be 270pF (27 * 10 ^ 1). 16 is the voltage. I think 5K means Max temp of 85°C / 10% tolerance. Could you post a pic of the cap?

Replace the cap with like for like if you can. Get your PSU checked out professionally as well (oscilloscope tested), just in case something funky is going on.
