Apple Authorized Service Providers are third party stores and companies that provide service for all iMacs, though obviously for a fee for out of Warranty repairs. Look for one in your area.
Hope this helps
I found one near me but they are asking for £60 per hour + VAT (works out to be £70.50 per hour), which is just silly money. I guess I'll just look for a power supply and if that doesn't work I'll have to sell it and buy a new one.
