I am currently in the process of putting together components for a new computer build. (as Mr Cranky well knows) :wave: I was talking with a 'gamer' at work about the components which I will be putting together over the weekend. (I'm NOT a gamer) He advised that with all of his gaming computers' he 'grounds' the PSU to the case with a ground wire connected from the PSU to a non discript area under the MB. This a list of the MB and CPU I will be installing: GIGABYTE GA-EP45-DS4P LGA 775 Intel P45 ATX Intel Motherboard Intel Core 2 Duo E8500 Wolfdale 3.16GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor My question is: with this arrangement, is it necessary to have a physical ground 'wire' going from the PSU to an area underneath the MB? Obviously the PSU must be grounded obviously all circuits must be organized in a manner that properly uses the positive and ground config. I'm asking specifically if the PSU needs a wire ground connected to it leading to the computer case? Thanks!
