Default Is this normal? Arcing inside new PSU!

Hi everyone,

I recently bought a new PSU it's a Coolermaster SilentPro 700M. Lastnight, while I was messing around with cables and stuff at the back of the case. I noticed that there was a small intermittent arcing of electricity inside the PSU kinda like it was shorting out. When I look closely it appeared to be coming from the inside of this orange transistor like tube. Is this normal? or do I have a faulty PSU?

Thanks

i would say..


unplug and return to point of sale.

that is, unless you want to fry your pc, and quite likely, your house.

That was the first thing that come to mind. But since the arching is contained within this glass tube and not arcing between components got me thinking that it could be a normal thing. Imagine those glass plasma ball thing where you put your hand on it and you get electricity arcing all over the place

Would be good if someone with the same power supply could look in the back of theirs.

He's joking, that's a picture of Nicola Tesler. Famous for producing machines that made huge arcing lightning effects, among other things.

Look up Tesla downunder, he is a member on here, put a tin foil hat on and lets the arcs fly while in a swimming pool.

Electricity, arcing and Normal, those 3 words never belong together....
Unless the glass tube you refer to, is a neon tube, in that case, yes it's NORMAL.

Umm I know all about Nikola Tesla and the lighting machine etc.

What got me curious is that, this tube thing. Think a grain of rice size tube devided into 3 sections. The top and bottom section is coloured orange and the middle is clear. Don't know what it does but the arcing is contained within this thing.

It got me thinking that it could be some sort of viewing window that lets you see that it's working? and I don't think there is any danger, but I could be wrong. Someone with some electronic knowledge must know what it is.

You're not talking about a neon bulb are you?

Unfortunately most PSU manufactures steer clear of sending eletrictity through a medium such as air, due to it's unpredictable nature. Currently wires and circuit boards have this job. I would say it's time to whip the little fella out and take it back to the POS (Point of Sale errm)

That’s why I never recommend Coolermaster PSU's. I know it could happen to any manufacturer but, on the whole CM PSU's are just cheaply made. I always recommend Corsair, Antec or Seasonic PSU’s.

Could this mysterious object of wonder be a fuse that has blown in such a way that it's still allowing arcing to occur? It does happen sometimes.
