Is it OK to WASH PC Parts? Ft. Fixing a Dead CPU & Testing a Dead PSU

This is a crazy video where I manage to salvage the 1GB DDR3 ram stick that I sprayed with spray paint oh so long ago in this video - https://www.youtube.com/watch?v=YWimTXKi0TM

I also decide to wash the stick and scrub it down and then use a hair dryer.... and it still....

Another thing I tried to fix was a dead CPU (the i5-750 that had resistors that crumbled off the back), and it that didn't work at all, I am guessing the die was warped from heat stress from overvolting. I did use a circuit pen carefully to connect the broken resistor points to one another... but to no avail.

There is another test I do and that is to test a dead PSU properly, just grab yourself a spare mobo/onestick of memory and an old school CPU and you can test those PSUs like no tomorrow!

Then there was a question I had for myself since I have never seen a PSU (until now) that didn't have a Molex or Sata connection harnesses on it, so I decided I would test if a PCIe to Molex To Molex To Sata connection would work, and low and behold nothing happened, so I guess you can't do that... I will have to find another way to power my hard drives from this PSU.

And lastly there is a bonus in there on how to fully discharge your PSU before you clean it!

Enjoy! And if you have any questions or comments then be sure to go at it below.

***WARNING: You can NOT discharge capacitors inside a PSU like that! In switch mode power supplys the AC gets rectified into DC before it can get stored in the filter caps.
Shorting the AC input won't discharge the capacitors one bit because the bridge rectifier doesn't allow for any current to flow in that direction.

Once unplugged from the mains the AC input of the PSU is safe to touch (it would be very dangerous otherwise!), while the main filtercaps inside still can be holding a Charge of 170V DC ( for 120V AC mains) or even up to 340V DC (for 240V AC mains) this is NOT safe to touch! In fact it's the total opposite of that!

Do NOT use this "Method" if you plan on opening up the PSU. The caps WILL still hold most of their charge and you can get hurt!

Always, ALWAYS make sure to discharge / short out the main filter caps (usually big and round) seperately using a INSULATED screwdriver (preferably a wide flat-head screwdriver or simmilar) when working on PSUs like this and other devices that store rectified mains.

(Devices like LCD Monitors, Notebook PSUs, Class D Power Amplifiers, Flat Screen Televisions and pretty much anything that uses a switching mode PSU)****
