I was by my bed when i went to grab my drink and it spilled on the floor. Some of the milk went onto the back of the power supply so i wiped it off the back. It may have gotten inside the power supply but i'm unsure. The PC wasn't plugged in or turned on at the time of the spill and it happened about 13 hours ago.

Is my PC ok and do I need a new Power supply?

Specs are:

i7 3770
8gb ram
gtx 770

Since the PSU wasn't turned on at the time you will probably be ok. 13 hours is long enough for any moisture to evaporate, so you should be safe to try and turn your PC on.

**Be aware that although you will probably be ok, there still is a slight risk of damage to the internal components of the PSU since milk will certainly leave a film on anything it dries on. If you aren't at all willing to risk your other internal components due to a PSU malfunction then go ahead and replace the PSU.

Only way to find out is to turn it on. If you think any milk has gotten inside, disconnect the MB, drives and anything else connected to the PSU. I might not worry about the fans to much but do disconnect the rest (use the PSU switch on the back to shut it off. Leave it plugged into the wall while disconnecting). Then turn it on. If it does not shut down or produce any smells or smoke after a few minutes, shut back down and reattach things. I doubt you have any issues but best to be sure.

It's good that the computer was off. You must open up your power supply and inspect it for the milk. If you see no milk residue, you are OK.

You have to look for milk that would cause a short circuit between components. Even dried milk may cause problems.

While you have the computer open you may as well clean out any dust you find in it. Make sure touch the computer case before touching anything inside the computer for grounding purposes.

So your tellng me to take the PSU out the case and unplug it from everything, and turn the PSU on with just the PSU plugged into the wall socket?

If you want to be extra careful, do what Dogsnake suggested above. Remove the power cables from the rest of your components and just have the PSU connected into the wall. Power on the PSU and see what happens, this way if it is faulty only the PSU will be harmed.

If nothing bad happens right away I'd leave it running for a little while before you plug your periphreals back in, just to be safe.

I would open the PSU and take a look inside to see how far the milk might have gone in and what it touched. If it got on the PCB on the primary/HV side, you might want to clean it off using isopropyl alcohol and cotton swabs. On the secondary/output side, the voltages should be too low for dried milk to cause significant leakage current.

I'm not willing to open the PSU, I'll just buy a new one as it'
s discontinued anyway. What PSU can you recommend thats
modular and not expensive. I live in UK.

np mate,you wont have any problems though - its impossible to plug the wrong cables in - everyone is shaped differently & will only fit in the back of the psu where theyre meant to.

While caution does not hurt, the 5VSB rail in ATX PSUs will drain even the largest input caps most of the way long before you are done pulling the PSU out of the PC to remove its cover: by the time the 5VSB LED on the motherboard goes out, voltage across the input caps is typically already in the 50-80V range and that happens 20-30 seconds after removing power.

With even dollar-store AC-USB adapters and night lights having bleeder resistors across mains-connected caps, finding a device that holds a charge for minutes after disconnect would be highly unusual these days.

Without going crazy here, just shut the psu off with the switch at the back of the unit. Open the side of the case and disconnect the 6 and 24 pin connectors, and any other leads to drives-video cards-other items that connect back to the psu using the psu wiring. Turn the psu on. Leave it on for a few minutes. If nothing odd happens then shut back down and reconnect things. Start it up and go from there. Do not open the psu to try to clean or inspect it. If it fails on turn on remove it and return it for replacement. Let the factory decide if it is warranty..ya never know. Even a full glass of milk would need to some how splash very hard to get much past the back of the case and into the rear grill of the psu. I really think you are OK.

Another thing. Stop drinking milk. It is meant to fatten and feed cows not humans. Find another drink more suited to the nutritional needs of humans unless you are a cow posing as a human? The only milk truly good for humans comes from the female breast. If you want milk get a wet nurse and never worry about spills into your computer.
