HCP850 tick sound

[Mayoo]

Hi all,

My new HCP850 does a "tick" sound when I turn off the computer (when the PSU doesn't need to work anymore).

Is this "tick" normal? If so, where does it come from / why?

Thanks all.

Is it the fan running on for a little while after shutdown? I never shut my PCs down so wouldn't see this behaviour, but IIRC, some PSUs keep cooling until they hit a certain temp.

I will have to look closely but I don't think the fan continues to run. The "tick" sounds seems to come from capacitors any any other components other than the fan.

Well, I know my PSU being an HX750 does tick between bios to windows loading, another time loading into windows, and another time on a shutdown slightly before it powers down. If it is just one quick click, I wouldn`t worry to much about it, alot of power supplies now ship with caps that hold a larger charge, it needs to disappate, or for that matter "switch" to do whatever the hell it likes to do, usually a sounds something like a pop button or something along those lines, I am assuming its normal behavior for the way they are designed now, have heard other folks mention it as well. I think I would rather hear a "click" then coil whine any day of the week. Its kind of a comforting click once you get used to it, its letting you know its happy :P

Hi all, I just noticed there is also a small red light flashing one time when the tick occurs.

I guess it is a LED or something? Antec won't answer me :(

If your worried about it, set an RMA up, most decent companies will RMA a noisy PSU no questions asked.(I know corsair does for loud coils)

sounds like a relay doing the ticking when PSU switches modes(caps are filled an ready to work), as to red light is warning that not enough juice suppling unit or site fault wiring

Ok, if I understand correctly, either the juice is beeing bottlenecked somewhere or faulty wiring in my house?

My condo is built end 2010, used for demo and I moved in late-May 2011. The only thing between the comp and the wall plug is an IGo Green Tower power bar. The PSU power cord is the one provided with my old Quattro 850w.

@Adzsask: Here is my last 2 or 3 months

TPQ850: Boom, RMAed (took one month). Fries up both GTX570 (replaced with refurb (no ASUS stickers) :S)
TPQ850: Whining sound, RMAed (took one month)
HCP850: What I just explained.

My computer is new from end-May 2011. Changed so far:
2x PSU
2x GTX570 (SLI fried up)
1x BluRay drive (whining sound, probably caused by first PSU boom but RAMed easy with LG)

So yeah I am tired of waiting for new parts .

Well i think it might be antec slipping, my friend has put 3 PSU's into his PC I built him in a year! all antec, so maybe this isn't just a freak thing and the quality of the units are suffering(BTW I RMA'ed his last PSU and sold the new replacement, tossed a seasonic in no more problems)

[Mayoo]

I will see to do the same then (if the unit is defective afterall).

What would be the best replacement? (see my specs)
