The number 1 risk to your Commodore 64 is the ancient power supply. If this goes faulty it could cause your C64 to fail leaving you with an expensive repair bill or even needing to buy a new one. Worse, original C64 PSU's aren't very serviceable. Why can't C64 owners get a new PSU as easily as Spectrum owners? Well it's down to the dual 5v DC and 9vAC voltages. But now some boffins in Poland have come up with the answer. A brand new C64 PSU with built in over voltage protection! We take a look and invalidate the warranty!
