Introduction

The Power supply is a component that has become increasingly important in recent years as the wattage requirements for parts ramp up and customers become more aware of their system’s impact on the environment – and their wallet.

Because of this many companies have begun producing PSUs, leading to a pretty convuluted marketplace, making it hard to decide which one to go for. While XSR doesn’t have the budget for a full power supply test run, we can do a couple of quick checks which will let you know whether you can put a unit on your maybe list, or strike it off altogether.

Today I’m looking at the Thermaltake Smart M650w unit. Let’s see where it belongs.
