Power Supply Screech

Drake5 · 21 Apr 2012 at 17:46

I recently had a new Corsair CX 430.

When I was unplugging cables from the back of my PC (PC Was turned off) I noticed a sequel like sound coming from what I think was the PSU.

I'm not to bothered by it at all, just wanted to know if it's normal for PSU's to do this when the pc is idle?

Cheers

no its not normal. u sometimes get a click when it powers down but thats about it

the cx 430 is notorious for the whine

jamesfreddie · 21 Apr 2012 at 17:57

I have used about 5 of these PSU's. 4 of which where 430W and 1 600W

The 600W went bang within 3 weeks, and all the others whined all the time.

It does only happen when the pc has powered down, a whining noise would be accurate to describe it. Kinda changes pitch a lot.

So it is normal?

Drake5 · 22 Apr 2012 at 13:38

So does anyone know if this is normal for the PSU to still be making a noise even when the PC is totally powered off?

Cheers

opstrat · 22 Apr 2012 at 13:49

u mean when the computer is off its still making the noise, or is it like a second or two after u shutdown?

Drake5 · 22 Apr 2012 at 13:50

When it's off it's still making the screeching noise. Not sure how long it goes on for though.

capacitor defect? use a torch to see if any are bulging/leaking

opstrat · 22 Apr 2012 at 13:54

get it sent back mate, best advice i can give

Drake5 · 22 Apr 2012 at 14:00

I have taken a look at the Corsair forums and seen some other people are having the same issue. I really can't be without a PSU though as that'd mean I'd have no PC to use.

Not sure what to do...

farlow2012 · 22 Apr 2012 at 14:52

order a new one asap then send it back for refund

Drake5 · 22 Apr 2012 at 15:03

I'll contact OcUK tomorrow and see what they suggest.

Cheers

I notice the CX430 is now out of stock so I'd struggle get a replacement anyway.

Which others would you guys suggest for around £40 region?

Thanks

This one?

Seasonic made, usually pretty good but no idea whether this one will be any good though.

Drake5 · 22 Apr 2012 at 18:38

I'd go for that one, would appreciate any opinions on weather it's a good choice or not though.

Don't want another that's going to scream when the PC is turned off or go bang on me after a months use!

Cheers

Interesting, seems to conflict as the OCUK page states "80 Plus Bronze", yet that page shows the model number to not be certified?

As it is still Seasonic, and rated the same [power wise] I'd still say its a good choice
