Enermax Liberty ELT620AWT 620W Power Supply Review

Power supplies used to be the least-sexy component in your PC. Power supply makers spent their marketing dollars on convincing us of the benefits of quality power versus fancy bells and whistles. That changed not too long ago when customized cases came into vogue. Now you can buy power supplies with neon lights, blinking strobes, and just about anything else desired to pimp your rig. But product differentiation doesn't end at cosmetics thanks to recent hardware innovations and requirements. Modular connections were introduced in 2004 and have become a popular feature. The SATA IDE and PCI-E interfaces added new power needs, as did the return of dual video cards. Reduced noise and heat output are also high on the desired features list. And don't forget the potential replacement of the ATX form factor with BTX.

Enermax is a well-established and respected supplier of power supplies (among other things, including cases and various peripherals). Their new Liberty line of power supplies is intended to address the need for style and features and, of course, reliable power.
