EVGA SuperNOVA NEX750 PSU review

Posted by Hilbert Hagedoorn on: 01/07/2013 09:40 AM [ 8 comment(s) ]

Certification and Efficiency
Tweet


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?

Corsair AX1200i PSU 

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% LoadEfficiency at 50% LoadEfficiency 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.
