I am doing a test if the power supply.Can you have the computer on and plugged in with PSU out in the open, leave on the carpet ?Can you have the power cable plugged into the psu first and then try to plug in the psu cable into the mother board. Would this electrocute you? if you accidentally knocked over liquid onto the power supply while the computer is running and you touched the motherboard at the same time while you are perfectly grounded. Can this electrocute you? unpluging the psu connector while the computer is on?
Power okorder /... Look at the photo all the way to the right. Shows you the motherboard power cable plugged in. That is the backside of the connector you're looking at. The jumper wire goes to the Green wire socket, and the Black wire socket next to it. Pins 14 15, in this type of motherboard connector. No matter what style of motherboard connector you have, it's the Green wire, and any Black wire. Green is the Soft Power On, any Black wire is a ground. Just touch it - Briefly. You'll see a spark. If the Psu is good, the computer power supply will turn on. (The spark may make you glad you had a rubber glove on!)
I'm willing to bet that there's people out there who'll debate me on this, but the answer is a nutshell both yes and no. Part I: As for having the power supply out in the open the answer is generally no, assuming you have it on a non-conductive surface such as a sheet of cardboard, assuming your carpet has any grade of nylon in it, and assuming the wiring in your house is well-grounded. Part II: I doubt it, but it'd be a better idea if your plugged it into the motherboard first, then to the power supply, then the wall. Part III: Both yes and no. It really depends on a small number of factors like how well grounded (electrically) it is. However, liquids and electricity of any type are NEVER a good mix. Part IV: Don't even think about it. Aside from something extreme like oh say a fire, there's no surer way to kill a motherboard than to disconnect the connector while powered-up.
If you have already pulled the fan off, do so again (without reaching into the power supply. Take a good look at the shaft of the fan. I'll wager there either is, or was, a set screw in that shaft. Most likely you'll need a hex wrench to get that locked back into place. This would also explain the lack of air flow when it is working without making a racket. Good luck. Best regards, Jim
You can but I wouldn't I build PCs all the time in test configurations outside of the case, but I always have everythign on non conductive serfaces, ie wooden tables. Carpet would be a little to staticy for me. Your second scenario leaves two answers for me, both are no, but for different reasons. If I plug a psu into a motherboard with power allready in it, I could short out the motherboard or worse yet shock myself. Also, I don't want to plug a power cable into a psu without any load on the device, doing so can and will fry the psu. depends on the liquid, if it is dionized water, you can turn the pc off dry it out and may be lucky enough not to fry your system. if it is soda,tap water, or salt water of any kind, don't touch it. I don't care if you THINK you are grounded, even if you were, the current would still flow through you, and if you pulled away, out of sudden suprise, then you would get electricuted, not good. Unbluggin the power cord from the powersupply will not be the biggest problem, unless you have very sweaty hands and the air is very dry. Just don't play with electricity
