Not sure if i should be concerned or not

[Absorbentsolid]

About 6 months ago i purchased the Super Flower Leadex GOLD 850W Fully Modular "80 Plus Gold"

Just today i started my PC up and everything wasn't running like it usually did, my PC would start up for about 2 seconds then turn it self off and over and over again.

I made sure everything was okay when it comes to making sure all leads were plugged in correctly etc and it just wouldn't budge.

Now after hours of trying i have my PC running like it normally does but sometimes i get a slight buzz and hum noise to it.

and that's idle, after leaving it for a few hours it seems to be okay now but i haven't really tried anything on it as i'm worried it might blow.

Is this normal as i've never really noticed it till today, as it just comes and goes, i can't seem to replicate it right now,

but if it does it again should i try anything specific?

Hope someone can point me in the right direction.

I am having this exact same issue, The exact same power supply also!

My power supply was purchased over 2 years ago but the symptoms you describe are exactly the same and it's driving me crazy.
I have asked Overclockers for details on the warranty of the power supply because I don't trust it any more and I really don't want it damaging any other components if it goes bang.

"EDIT"

How is the power supply?

Mine finally died and will not power up at all now. It tries for a split second but then switches off

On the other hand I caved in and purchased a replacement EVGA Supernova GS = https://www.overclockers.co.uk/evga...plus-gold-modular-power-supply-ca-03e-ea.html

All is well in the world once again
