Efficiency Deficiency

Wattage, price and efficiency - why low quality PSUs are not going to cut it.

When designing a PC, components which affect performance are typically assigned higher priority. For instance, the CPU, GPU and RAM. Enthusiasts will also ensure that the motherboard is of high quality, has an array of expansion capabilities, good overclockability, and will perhaps spend extra on a decent CPU cooler. Next up are the HDDs and possibly a pretty case. What often gets left to the bottom of the priority list are optical drives and the humble power supply unit (PSU). Professional PC designers, however, will place the PSU amongst the high priority components. The PSU is the difference between a functional PC, a PC that constantly crashes, and a PC that turns to a crisp during a power surge. In fact, it's one of the most important choices during the design stage.
