water on Power supply and battery

To the moderaters i posted this under systems last but realised i wanted under componets sorry for reposting .

Hello everyone i have 2 issues i really need advice from please read through part 1 and 2 before answering thank you ! XD

Part 1 - Electric Height Adjustable Desk

So i went into town to buy a electric height adjustable desk and it been a bit rainy all day i went into kinda a warehouse full of furniture and brought one. After i made the purchase i realised it was a really old warehouse with a rusty roof with holes EVERYWHERE and im a really paranoid person and i instantly thought what if water got on the desk and get into the motor or the battery. Anyway i kept going and got it on the trailer. On the way home it started to rain again i quickly pulled over to cover the desk with jumpers and anything i could find in my car. By the time i got home i was so paranoid that water had gotten into the battery and motor and im so worried thinking what if the battery bursts into flames or explodes and burns my house down? can this really happen?

i have the technical data i wrote down below
Frame height - 660 - 1180
Desk height - 685 - 1205
Maximum load - 100kg
Voltage - 100-240 VAC/ 50/60 Hz
Consumption - 80 WATT
Safety cut out
Conset motor

Part 2 - computer power supply

So when i got home i moved all my stuff off my old desk and i knocked over my water bottle on the carpet. it was right near the back of the power supply and i don't know if some of the water had splashed into the back of the power supply where the on and off switch is if you know what i mean?. What would happen if i got water in the power supply while it was running or off? will it explode? or burst into flames? im JUST SO PARANOID right now its been 24 hours since i knocked over my water bottle near my computer. My computer seems to be fine right now does it take time to damage the power supply?

thank you reading any advice is much appreciated! XD

I can't answer part 1 of your question.

For part 2, was the computer turned on when you spilled the water? If it was on and it didn't short out right away, you are probably fine. If it was off, and you have since powered it on, and it didn't short out, then the action of the PSU fan and the heat in general probably already evaporated all of the water. If it was a sticky liquid like soda or fruit punch, that would be a different story as it could degrade the components inside over time, but not water.
