Antec True Power 650 Whine

Is it acceptable for a psu to whine especially when pc is off.

PCs are rarely "off" unless you unplug them or use the physical switch on the PSU.

From what I remember, if its a high pitched whistling whine, then its most likely the metal plates in the transformer core vibrating where the plates are loose.

It could also be a dry solder joint on the PCB.

I had the same! I posted for support from scan so I'll quote myself on that.

Hi, I received this yesterday. All was well and thought great, it's dead quiet but then after I turn my PC off it starts to give of a high pitched whine. After I turn of the power switch or unplug it the sound fades over about 15 seconds.
I left it plugged in over night to see if it might just take a long time to fade but alas this morning it's still making a high pitched whining noise.
I don't think it happens while it's on unless the fan masks the noise.

I didn't find many results from google search but I did find a user review saying

I have purchased two of these in last 3 weeks and they both have a high pitch whine, the second one whined at a slightly lower pitch. Clearly audible with head near to PC and just audible over the other side of a quite room.
The whine is only noticeable when the PC is shut down and remains indefinitely unless it is switched off from the plug socket.

It wouldn't surprise me at all if they all do this but people are unaware.

I don't want to be a hassle with returns but I don't find it acceptable or something I can put up with. Are there any tests I could run or you could do on your end?

What are your suggestions.
Thank you very much.

How loud is yours? mine you can just hear normal sitting(or sleeping) distant when in a quiet room.

Sorry if I'm pushing in on your thread but can I ask a question to Antec if you think it's a problem with all or a batch of them or am I just very unlucky? (shall I refund or swap)
Thanks

Hi Fadsarmy/Tiaza,

It is not normal for our PSUs to give off any kind of high pitch whine. If the power supply is already out of the reseller's 30 days exchange policy, please click on the link below to request for RMA from us directly.

It could be a capacitor whine. Not exactly a sign of failure but not exactly confidence inspiring. My ATP650W is as quiet as a mouse FWIW.

I have rma'd it twice. This is my third unit and it still whines. This is even without installing the psu. As soon as I connect power lead it whines. This is very bad from Antec. I will RMA again. Each time it costs me £10 for postage.

Will you pay for postage since Antec is at fault?

Hi abitlover,

I am sorry to hear that you are still experiencing issues with this PSU. Go ahead and fill out the RMA form once more and include the previous two RMA # and ATTN: Eric in the problem description box. I will see what I can do for you.

Thanks

If that had happened to me 3 times then i would probably get a different model PSU or go with a totally different brand. I'm having the same 'whining' issue at the moment with a Corsair PSU and it's exactly the same as you describe as it whines when the PC itself is off, but the PSU still switched on at the wall.

It's also very annoying when reputable companies such as Antec don't provide a 'collect and return' warranty like most other companies.
