80mm x 15mm Quiet fan needed for Mini ITX PSU

[POB]

Hi,

I'm trying to find a decent 80mm x 15mm quiet fan. I have a Mini ITX case (its a very cheap £30 one inc a 250w PSU)

Taken apart the PSU and found it has a slimmer fan in it 15mm.

I can't seem to see one on OCUK?

Anyone have any ideas on a decent manufacturer of slim quiet fans.

On a separate note is 250w enough for :

i5 2500k
8 GB ram (2 x 4 gb)
Intel graphics only.
1 x 7200 RPM Disk
1 x SSD
1 x DVD

As if its not I may be better finding a complete replacement PSU.

Thank you for your help.

In the end I discovered a rather nasty green coloured Hiper Flow, on eBay which is think is discontinued.
