510W Danish Chill Innovation CP-510A PSU
 

The Danish company Morgen Gruppen A/S has since the launch of their extremely quiet CP-350A been working on more powerful versions - and they’ve now finished development and can proudly show off their new CP-510A, a power supply which should be able to power even very powerful systems with its 25A on the +12V rail, and that with an extremely low noise level of only 1-2 dB above ambient.
