We already know 80 plus bronze doesn't tell the whole story nowadays
80 PLUS
any color/metal doesn't tell the whole story. Never has. All those certs tell us is how efficient a supply is
across a variety of loads. And it is this "
variety" of loads that matters.
A typical electronics PSU is typically most efficient at only one load level. Efficiency typically falls rapidly off on either side of that level. The efficiency curve will look like a bell (hence bell curve). This is NOT a problem for many types of electronics that have a consistent power demand, and so present the power supplies with a consistent load. A TV or monitor, for example, will have a pretty consistent power demand so engineers can simply match the TV to a power supply that is most efficient at that power load.
A computer, on the other hand, will demand peanuts when idle, all the way up to several 100 watts when tasked. So a computer power supply that presents a "flat" curve across a full range of loads is desired. That's where 80 PLUS comes in.
80 PLUS certification just says the supply will be at least 80% efficient at 30%, 50% and 100%. 80 PLUS certification does
NOT automatically imply the supply is more reliable, made of higher quality parts, has better regulation, or better ripple suppression. And while Gold ensures better efficiency than Bronze, the criteria for Bronze "nowadays" is the same as it always has been. The only difference from these days and those in the past is consumers perceptions and expectations - due in part to the much greater availability and affordability of Gold and higher rater supplies.
Lying on 80 Plus has been a thing for God knows how long...
This is true. That's why I provided a link to Plug Load Solutions to verify if Segotep was lying or not. And they aren't - at least not with the listed supplies.
