Hi guys.

I have a setup that the PSU is located on the computer case, instead of inside (and 1 side of the case is open so the wires get in).
Accidentally spilled a little bit of water on the table and apparently some of it splashed into the PSU (and there's a little possibility that some got in the case as well). What happens, computer instanteously turns itself off, leaving only the external HDD on. I look at other appliances to see if this is not electrical failure to find that it's not (silly me, the external HDD was working...), so I figure it must've been the water. I turn off the HDD. (This often somehow makes the discharge power on the whole computer for no known reason and so it did also this time). Computer starts powering up, I hear the loud GPU ventilator, but then it quickly settles down. I think I might've heard a chizzling sound, but that could've been my mind as well. Okay, so I press the power switch on the PSU and shut it down. Then unplug the power cord from the PSU as well.

So the question is, what should I do now? Of course, I want to do no harm to the internals of my PC, so I guess blind powering on is not the best option. Drying? Disassembling? Unplugging cords for PSU? Thorough internal examination? Give me something to go for.

Regards, Aigars

don't know how long ago it happened but if its not dried out yet you should not be turning it on until you have dried it out ,you can use compressed air ,to blow away the water ,a can of electrical contact cleaned might help also, you may have to take the cover off the psu to get at the water,make sure to unplug it and hold the power button in to drain the power ,but i caution that you need to be very careful when inside a psu ,as it dose have the ability to hold power and can be dangerous ,but you need to let it dry for at least a few days before ever tuning it on .

Happened just now, like 15 minutes ago. As for the drying, well, don't really know a way how to see if it's dried out or not, it's not like I see a wet spot anywhere at the moment. So should I just wait it out for a few days or should I get some compressed air and muzzle it through the whole thing?
How about disconnecting the wires from the components - any point doing that?

let it sit for at least 24 hours or more, 48 to be safe, before trying to turn it back on would be my suggestion.

The large capacitors inside the PSU hold very high amounts of voltage which makes opening the case and poking around inside very dangerous. If you are shocked by this voltage it could even be fatal.

I would suggest following the_patriot09's suggestion to allow it to dry for a couple of days.

Thanks for all the replies, guys.
Let it dry throughout the night and fanned it with stream of air, everything seems fine now.

Cheers, Aigars
