I have a Corsair 620HX for quite some time now, 3 years or possibly more. Lately it has been making a very loud noise whenever it's turned on at the switch in the back.

It sounds like a loud bang.. more like a snap, or the crack of a whip rather than a bang. It's difficult to explain.

Is this something that should worry me. I've recently upgraded my rig, so I took everything out and put it back in but it was doing in the previous rig and in the previous case as well. It's been happening for about 3-4 months or so.

Is this something I should be worried about? as in my power supply is living its last days?

You could just be trading one problem for another.

The EVGA SuperNova models made by FSP group seem to suffer from voltage regulation problems. I don't think they've been selling very well either. I see EVGA offering a lot of rebate promotions on these models in an attempt to generate sales.

The Seasonic S12II-620 Bronze doesn't meet your 5 Year Warranty requirement. It only has a 3 Year Warranty. It also doesn't have the four PCI Express power connectors you would need for two Radeon HD 5850 in 2-way CrossFire mode.

The Fractal Design Tesla R2 650W doesn't meet your 5 Year Warranty requirement. It only has a 3 Year Warranty. It also doesn't have the four PCI Express power connectors you would need for two Radeon HD 5850 in...

Yes. You should be very concerned. Stop using it!! If something goes wrong with the power supply any component connected to it could potentially get "fried." If the psu is still under warranty contact corsair and get an rma. Otherwise, I would get a new unit. Good luck! :)

I think I'll contact Corsair then to see if its under warranty. It only makes the noise when it gets turned on at the plug so I tend not to turn the switch in the back just turn off the PC. I think I'll be contacting Corsair about an RMA tonight. :(

Thanks tho!

Sounds like it could be arching or something like that in there. Static discharge or something like that.
Clean it out with canned air and see if that solves the issue.
It is possibly on it's last leg, and there is a possibility that it could fry what it's connected to, but typically there are fail safes that only cause the PSU to fry, not anything it's connected to.

Do you think I should open it and clean it inside or is that not advisable? would dust cause a static discharge? I'll see what Corsair say about an RMA.Not sure if I still have proof of purchase but i'll look into it.
 


Opening it will automatically void the warranty, if any remains, so it's not advised if you're planning to RMA it.

Corsair accepted the RMA request and the courier is collecting it from me today at some point to send it back to Holland! so yay for Corsair.

As this is the 2nd time a Corsair HX620W bails on me I was thinking about selling it when I get the replacement back from them and get something else.

I'm mostly concerned about noise levels and 80+ efficiency. I know that my current system uses max 440W with the HX620W. I measured it with an energenie. I got a FX-8320 and an ATI 5850 1GB card. So I don't think I need anything more than 650W so to say.

I had some models in mind.

http://www.amazon.co.uk/Fractal-Design-Tesla-Power-Supply/dp/B0093FTLT4

These are some of the ones I'm considering. I found them in different prices here and there.

I'd want 5 years warranty
Silent operation as much as possible
Not bothered about modular (I had used all slots in my HX620W anway plus my case Fractal Design R4 has plenty of space for cable tidying)
80+ % efficiency
Not bothered about looks or size or weight
I'd like non rigid cables but its not essential
I'm only going for around 600W in case I add a 2nd ATI 5850 in the future

I guess the important thing is the lack of noise coming from the PSU at 0-50% load.

Got any recommendations for me or any comments for the above PSUs? My budget wouldn't exceed £80

Many thanks in advance!

Both of these should meet all of your requirements and they use Seasonic as their OEM.

Yeah unfortunately I got sidetracked by the Seasonic USA website where it says 5 years on the S12II. Then I noticed on UK retailers they were saying 3 years warranty.
http://www.seasonicusa.com/S12II-Bronze.htm
Here it says 5 years so I'm kinda inclined to send em an email and ask em exactly what the situation is.

I had another thought about getting a molex to double pci-e x6 for the HX620W?

I read somewhere that in order to run 2 5850s you'll need at least 55-60A on the 12v rails which I think that the HX620W can do anyway, or at least close enough. I mean consumption wise it should be ok shouldn't it? Running furmark I'm currently consuming 355W on a Coolmaster Elite 500 which I borrowed from a friend until the RMA process is complete.

So the XFX ones are very quiet yes?

If yes then that sounds quite intriguing. A friend of mine has a 550 core edition. I'll ask him about the noise levels although he is not fussed like me about it :)

Thanks anyway ko888, all your answers are much appreciated!
 


A +12 Volt continuous current rating of 40 Amps or greater is recommended for two Radeon HD 5850 in 2-way CrossFire mode to handle the running of FurMark.

The XFX PSUs are quiet. I installed a 550W Core Edition in a friend's system. When I listened to the PSU to determine what the fan noise was like it was a lot quieter than the Delta Electronics 350W OEM PSU that was originally in the HP Pavilion desktop.
