We should probably say some thing like* make sure you read a little before you do this* if however unlikely there is a short in your board or some where else and you put it on a conductive surface while the PSU is running you could 1) destroy allot of hardware 2) die from a electric shock now I know people are gonna say thats very unlikely he will probably ware rubber soled shoes this and that but its better to say some thing now then after cnn finds him naked covered in PC hard ware.
Now it's time for me to give you as someone else gave me a low down on a different question. To answer you question I would need to have system specs. But the most in depth reason from me would be that 1 to 2 short years ago because of compliant issues powersupplies have had to redesign the way they work. So mainboard that work produced before then have issues with psu's that are newer. One example tho more than likely far from what you are working with is: *X-station from a company called bitspower works great with older psu's does not work with new. At least the first version of this device that was made. So what that tells me is that a issue lie's between psu,mainboard,and unit on a newer motherboard(mainboard). So with this is what I would want to ask you: Are you running a mainboard that is compliant with 1.92 or newer because I know that a corsair psu is!?
*(X-station is a device that allows more then one of the exact type of psu to be used on a single mainboard).
beenthere I wasn't making some jab and you and yes you said non conductive but people can do dumb things and even though yous aid what you said you didn't mention that not doing that could result in lose of life i don't see why me making a comment like that would upset you so much if it doesn't need to be said then who cares but if it stops one person from getting hurt then it should be said.
I didn't take your comment as a jab. You saw the wink, right?
As I said if somone doesn't understand the term non-electrically conductive they should not be working on PCs or anything electrical. The mobo is low voltage 12v and lower so the real concern is the PSU grid power. 12v isn't going to kill anyone but 120v will get their attention.
