Annoying noise from new PSU

13 posts in this topic

New PSU, annoying noise.

 

Sounds like a crappy fan to me, not sure.

 

Time to RMA already?

Here's a recording. There's obviously some ambient case noise, but the problem sound is that of the repeated clickyness... you'll know it when you hear it.

Thoughts? To me it sounds like a fan that has been used for years and the bearings are starting to die, it's brand new though :S

Sounds like a bad fan. If it is the fan, it could be a bad bearing or a wire in the way of the blades. I would troubleshoot the fan to make sure it is clear of other wires and do it with the side off of the computer case to verify it. I would RMA it while you can, if need be. Then, at least, you can get a new one regardless. (Y)

If you're going for a replacement, you should look into PSUs with a hybrid/0 RPM fan system, where the fan won't be used under low/medium loads. I recently bought the Corsair RM 650 and couldn't be happier with it.

+1 Barney said. Doesn't sound like coil whine which is a common annoyance when it comes to PSUs.

I suppose it's a relatively new PSU so I wouldn't tamper with it or give ebuyer any other reason to deny an RMA. The last time I used them over 7 years ago they had a premium rate support line and a very slow response time via their enote system. I used the latter as I didn't fancy racking up bills more than my order value.

You can speed things up by calling them and thanks to recent changes in legislation it's the same rate as a national call, their number is 0371 521 33 00

So I called the support number for RMA'ing the device....

 

 

Not sure what to make of their advice. (this is scan.co.uk)

 

They said turn the PSU the other way around because some power supplies don't support being mounted upside down :s

 

I noted that this case has an air inlet from the bottom and a dust filter, therefor, I don't think it'd be the best idea.

 

The rep then noted that if you have front mounted case fans and that cool air would actually help the PSU cool and that warm air rises, with it being a PSU based at the bottom of the case, this could work better.

 

I'm not convinced though, although I suppose I will try it.

 

What are your thoughts?

Orientation shouldn't matter in that case. Modern PSU can be mounted with whichever orientation matches the case they're put in.

So I rang international support at EVGA and when I asked if the PSU I have should support being mounted in both orientations in my case, they instantly hung up on me... twice :S

 

Anyway, I'm with you on this, it shouldn't make this sound either way around. Especially at the price I paid for this PSU, it's not exactly cheap or low end!

Sounds like the fan is unbalanced / manufacturing fault. It's only going to get worse or fail over time - seek RMA asap.

I always had better luck going through web RMA, then just calling them, as they don't know ######.

This is why I always order from Amazon. Seamless returns when something goes bad and customer services who give a **** instead of fobbing you off

Umm isn't there an offset screw? It can only be mounted 1 way..

Some cases allow normal or inverted mounting depending on the ATX version of the PSU (which side the fan is on).
