NON grounded PSU electrifying case

[da_knug]

Hi, I sent this following message to the evga support:

I have an EVGA 650 GQ 650W power supply, that is NOT connected to a grounded outlet.

If I bridge the gap between the grounded water pipes for the heating radiator in my room and any grounded component in my setup (e.g. metallic keyboard frame, PSU mounting screws, ground pins on the power strip) with my hands I can feel a pretty strong electric current. No where near dangerous levels but definitely noticeable. Is this normal?

I have read that power supplies do by design suffer from some current leakage to ground, and by not using a grounded outlet this is a risk I am taking, I am just wondering if this level of leakage is normal or if it is supposed to be less, i.e. less noticeable if accidentally bridged to ground. I have never experience anything similar with any other computer.

They were quick to respond with offering me a RMA to send it in so they could take a look at it. Although since I am, for what I think are quite obvious reasons, not so keen on sending away my PSU to the other side of the globe for God knows how long, I wanna hear a second opinion. Have any of you experienced anything similar? Could this just be semi normal behaviour from the PSU since it's not grounded? 

 

Thanks.

What exactly do you mean by "pretty strong electric current"?

its hard to quantify, but its uncomfortable to hold the connection for more than a few seconds.

Pretty normal actually. My PSUs are grounded but there some minor electrical discharge from the case. My house floors are stone, so if I'm barefoot on the floor and touch the case(s), I can feel a mild electrical current.

I've had this it is completely normal if the psu is ungrounded, I recommend grounding it though.

Yes it's normal. Should be using a grounded socket.

where do you live in that this is normal?. this is not normal...

you should feel nothing if ground works no matter how weak current is

same goes to crappy psu

yah but i explicitly stated that grounding is not an option, multibple times.
