Got my CiT online from another outlet, cost 30 quid and is a nice, heavy piece of kit with sleeved cabling. I know they are budget brand, but its worked fine and is nice and quiet.
Ive seen guys banging on about how brilliant their 100£ Corsair PSU was, despite it blowing after 6 months and totalling half the kit in his pc. Ive never bought branded before and never had a PSU last less than 3 yrs or damage anything else when it blew.
