Today, the easiest way to discover the real manufacturer and the real model of a given power supply is by analyzing its 80 Plus report. Of course, if the power supply isn’t 80 Plus-certified you won’t be able to use this trick (in this case, skip to the next page to learn other identification methods).
This is possible because Ecos Consulting, the company behind 80 Plus, doesn’t retest rebranded power supplies, they simply get the report of the original power supply and change the name of the brand and model. A complete explanation of this process can be read here.
Each 80 Plus report has a field called “Ecos ID #.” When a power supply is rebranded (i.e., an identical copy of another power supply), Ecos Consulting use the same identification number as the original power supply, but adding a “.1” after it.
So, a power supply with an Ecos ID # of “123” is the original power supply, while an ID “123.1” means the unit is a copy of the power supply that has the ID number “123.” It is important to understand that Ecos Consulting only started using this scheme more or less recently, so this standard is not valid for older models.
How can you discover the original manufacturer and original model of a power supply? First, open the 80 Plus directory and find the 80 Plus report for the unit you are researching. Open it and find its “Ecos ID #.”
Then, you will have to perform two Google searches, because the URL for the 80 Plus database has changed recently and Google isn’t fully updated yet:
Ecos ID# 123 site:80plus.org
Ecos ID# 123 site:plugloadsolutions.com
Of course you will have to replace “123” with the Ecos ID # of your power supply, removing the “.1,” if present. As explained, if the Ecos ID # doesn’t have a “.1” after it, it means you are facing the real deal, the power supply you have was really manufactured by the company that is selling it.
For a real example, consider the OCZ Z-Series 850 W power supply. It has “1495.1” as its Ecos ID #. After making our two searches at Google, we found out that this power supply is actually a rebranded High Power HP-850-G14C, because this power supply has the same identification number but without the “.1” after it. Not only that, we found out that the Thortech Thunderbolt 850 W is also a rebranded High Power HP-850-G14C (because it also carries the 1495.1 Ecos ID number), meaning that internally the OCZ Z-Series 850 W and Thortech Thunderbolt 850 W are identical.
