This Green Computing article will explain the history and benefits of 80 Plus, a standard that has been developed over the last six years. If you have read any of our other articles on the concept of Green Computing, then you are already familiar with 80 Plus.

This article is meant for those who are new to the standard and are wondering if they should make it a requirement the next time they buy. An 80 Plus introduction.

In our last Green Computing Review, we looked the 80 Plus Bronze PSU from Antec, the EA-430D Green. We built that power supply into our home theater PC. This time around, we need something with a little more kick to power our gaming machine.

In addition to our Core i7 860, 4GB of G.Skill ECO RAM, X-Fi, Blu-ray, and hard disks, we needed to make sure we had enough power for our GTX 470. See how the OCZ handles it.

In a veritable sea of PC power supplies, what makes one better than another? The first step is to skip the bargain bin. There are plenty of cheap unbranded power supplies that roll the dice on performance. That still leaves you with plenty of choices. My next step is to rule out any PSU that doesn’t meet the 80 Plus certification. In 2010 and beyond, there is just no excuse for a 65% efficient power supply. See how the EA430 fares.
