It is a Gigabyte GE-C420N-C2.

What would be a good unit to replace it that's not to pricey

It looks like adhesive to secure the toroids. If it is hard and the PSU works I wouldn't be worried, but I wonder why you opened it up ?

The pc kept turning itself off.Eventually the lights started flickering and then the fans ran very slowly and there was a lot of noise coming from the back.
Now there is nothing at all apart from a little green light on the motherboard.

If you have a multimeter then it would be a good idea to check the voltages, following the guide set out here for example:

If not then all you can do is to test by substitution of the PSU and or motherboard, else get someone to look at it.

I'm pretty sure it's stuffed.Poor thing was clogged with dust and with burn marks around the case.
My old pc is on loan at the mo so I'll hopefully get that back tomorrow to change PSU.

The white stuff, as already mentioned, is OK.
I think though the problem is the bulging caps in the lower left of the photo.
Probably not worth trying to get them replaced (There may be more that aren't showing in the photo), just buy a new PSU.

Thanks for clearing that up.I'm looking at this at the moment.Basically the same PSU as the one in my old PC.

I see bloated Teapo trash.

Replace them and it might be OK, the build quality doesn't look too bad otherwise.

Another cheap branded PSU and it's 2nd hand. That's just asking for trouble, wouldn't be surprised if it also had capacitors on the way out.

Either buy something brand new that's good quality, or do a recap of your old one. That way you'll know the thing is at least half-decent.

I have looked on the Ascent website but there are so many.
This is what I have so far

I forgot to mention that this is a friends computer.It has an Asus M2N68-AM PLUS motherboard running onboard graphics.
The current PSU has a 20+4 pin.
I'll chuck a photo on of the case so you can see how much room there is.

Yeah, my first impression was also that the caps at the left had a slight bulge. While this indicates ill health, it does not necessarily point to the problem.

I'd give the mothorboard a good look over for other caps with a bulging top. Also beware caps that are on a lean (blown out their base plug) or oily staining of the mobo centred about a cap, or caps that have leaked a crusty substance out the top.

As for the case - tons of room for a new PSU.

PSU is dead.
Just put in my old Highpower 350w and it fired up.Now to go shopping for a new one.
So I should be safe with a Antec,Corsair,Silverstone round 450w?

Yeah it'll do. Not the best but far enough from the worst.
