Whatever happened to NVidia's "ESA"?

[VirtualLarry]

It was supposed to allow you to do things, like monitor your PSUs temps and fan speeds, etc.

Whatever happened to this standard? It seems like it never really caught on.

I wouldn't mind monitoring the temps inside my PSU while operating. Sounded pretty neat to me.

Having no clue what you are talking about dont laugh at this if its dumb lol.


Wouldnt this require hardware inside the PSU? how would software accomplish this?

not only would you have to have sensors inside, you you also have to have a way to communicate that info back to the system, and as far as I know, neither power supplies or motherboards have no way to to interact other than for fan speeds and voltages.

That is what he is saying, they would have a way to do that...aka new standard.

proved to be more of a painful PITA so they got rid of it.

was much easier to impliment PWM on the controller like sunbeams, and use it that way.

i kno wat hes talking about and i think some did have a way back then. i had an old antec power supply that had a three pin fan connector comin out of it with only the two outer wires that i never figured out wat it was for but it could have been somethin like that.

no it was a little controller that looked like a knobless fan controller that would connect directly to a ESA certified board.

This allowed u to set fans at settings according to CPUID values.



The ended up causing more headaches, because they werent greatly made, and the current handle on them were absolute crap.

To add to what aigomorla said, that 3 pin connector was only to monitor the rpm of the power supply fan. It only had ground and the signal lead and sometimes only the signal lead and plugged into a fan header on the motherboard. Some board have a header labeled specifically for the PSU.

What the OP was referring to was a standard that would relay more info back to the system than just the fan rpm.

I think ESA died when NVIDIA started to retreat from the chipset business.

Great idea...but I'm sure the application was more of a PITA than it was worth.

The Cost of the 1200watt PSU alone, was over $500.
