What is the power supply rating system?
A power supply needs to run at 80% at an absolute minimum, hence the naming convention.
How do 80 Plus ratings affect PSU prices?
First off, we can touch upon the PSUs that are not 80 Plus certified.
I would only recommend power bricks that have been tested and certified.
However, it’s common to spend double (even triple) this amount depending on the manufacturer.
The pricing against the power efficiency increases once more with power supplies that are rated 80 Plus Titanium.
How important is 80 Plus certification for PSUs?
The 80 Plus rating system is entirely voluntary and not required for any company to release a power supply.
A Chroma 61845 3-phase 45 kVA voltage source is used in testing 277V, 480V, and 380VDC.
The process is repeated at 10%, 20%, 50%, and 100%.
We recommend thoroughly reading through the 19-page document for full clarification.
