It's pretty amazing how efficient the lowly PC power supply has gotten. Five or six years ago the average power supply was about 55% efficient, upper end ones may have been as much as 65%. Today the average name-branded PSU is 80Plus rated, many of them over 85%.

So what does that mean to you? First, you can buy a smaller high efficiency power supply to do the job of a less efficient larger one, for example, an 80+ 600 watt PSU will do the work of a 700-750 watt PSU that is rated with efficiency in the low 70s. Second, the higher efficient power supply will use less energy from the wall, meaning less money on your electric bill. Third, the more efficient power supply isn't working as hard, meaning less heat and longer life. And finally, since the power supply isn't working as hard, you are getting cleaner power to your rig's components, equaling longer life for them, and more stability, especially when overclocking or otherwise stressing your system.

Today I will be looking at the highest efficiency rated power supply that I have received yet, the OCZ Z Series 650 watt power supply. With efficiency rated at over 88%, this power supply is 80Plus Silver rated. It sells for a price that won't break the bank and is SLI certified. Read on to check out the OCZ Z Series 650!
