Certification and Efficiency
Certification
So then certification, tested by the 80PLUS organization (the people that certify and test efficiency). We already explained a little what that literally means. But what does such a certification entail?
Well, we have standard, bronze, silver, gold, and platinum certifications. A PSU that is certified 80 PLUS Gold or 80 PLUS Platinum is more efficient than a normal unit. Below you'll find a table that shows what efficiency levels a PSU has to achieve at a given load to make the grade for a specific certification level.
| Efficiency at 20% Load | Efficiency at 50% Load | Efficiency at 100% Load | |
|---|---|---|---|
| 80 PLUS | 80% | 80% | 80% |
| 80 PLUS Bronze | 82% | 85% | 82% |
| 80 PLUS Silver | 85% | 88% | 85% |
| 80 PLUS Gold | 87% | 90% | 87% |
| 80 PLUS Platinum | 90% | 92% | 89% |
The EVGA SuperNOVA NEX750 Classified Power Supply is certified by the 80PLUS organization to deliver a 90% energy efficiency at 50% load and still 90% efficiency when your PC idles. We are not 100% certain if the product complies with the ErP (Energy Related Product) directive to ensure less than 1W of power is used in passive standby and off modes. We'll test that manually later on in the article.
I have a Gold rated 80 Plus report on this unit as shown above.
