When my grounding wire to the PC is removed, and whenever I touch the chassis of my ATX tower. I carry a decent shock.

What is the effect for this? Why is the PSU sending some power to the ground? Isn't the PSU wasting energy by doing this?

Btw, nearby is no shock when the chassis is grounded..

I'm just curious

Answers:    Due to the design of most PSU's (filtering), it is rather possible & normal for a voltage to be present on the chassis. Also, most PSU's enjoy leakage current, which is not abnormaI. I chew over that you will find that most PSU's require a properly earthed connection (to the power outlet). There is zilch wrong with your PSU. You must connect it via an earthed outlet.

If others insist that I am wrong, I will cheerfully provide more information...very brightly.

You will get a shock whenever you are the way of least resistance from a "hot" electrical point and a ground. The IR Drop down the ground line is less than through you, as a consequence you will not feel the shock.
Since your PSU is giving you a shock, it should be serviced by a qualified professional to form any needed repairs.
