[H] Does 80 PLUS really matter?

post #1 of 21
Thread Starter 
Quote:
A HardOCP editorial about the 80 Plus® program and how it is changing the computer power supplies you are buying. Is this good, bad, or ugly, and should you care? Did you know that you paid for that 80Plus rating on your shiny new PSU? Certainly PSU efficiency is a great thing, but what about the rating system?

Looks like I'm buying bronze from now on...

I read this article yesterday. REALLY interesting read.

I am not surprised by the findings and the problems with the standard.

Like anything else edgamakated purchase is edgamakated.

I almost feel like I should post the same thing twice now too...

Why page 1 of that article is irrelevant:
The fact that some manufacturers may 'cheat' the system is not a problem with the certification. It's a problem with the system and enforcement thereof.

Why page 2 of that article is irrelevant:
They did a comparison of the power and money savings between each 80-plus cert using only hypothetical numbers (no real measured numbers). And they did not include in their comparison any non-80-plus power supplies. There is theoretically no limit to how inefficient a power supply could be without that cert. Which if mentioned, would drastically alter their recommendations.
It is good to note that there really isn't much difference between each different 80-plus cert. But any cert is likely a vast improvement over none at all.

The best part is the last paragraph of the last page, where they list several reasons why the certification IS relevant, then conclude by stating: "just remember we think 80 PLUS® is irrelevant."

If there is cheating going on than that needs to be fixed.

Shortly after the standard was released I tested an 80+ vs. a non-80+ and found a ~33% power saving. I ran the same machine for an hour with Prime95 with each different psu. I used a killawatt to measure power usage.

I don't even care. I don't think i'll ever buy a PSU that someone like Johnny Guru doesn't recommend himself. (or... Phaedrus is it? O_o)

It was an interesting read though... tongue.gif
