    yes, I know eco means economy

    Ah! silent mode; then why call it eco?

    Maybe because the fan uses no power, the PSU uses less power and is therefore more economical?

    On a separate note:

    With the new 2% load requirements (60% efficient by 2019 and 70% efficient by 2020), PSUs are going to have to have a fanless mode. The fans use enough power to push the efficiency over the threshold.

    Not that the PSU in the picture can even do 60% efficiency @ 2% load. Just pointing something out.

    That makes sense (at low loads); always something to learn.

    Who required or recommended that? Intel or someone else?
    It's been a hard day's night and I've been working like a dog.

    It's in the new Intel DSG 1.4 and is there to help meet the CEC requirements and the alternative standby mode.

    What if they don't, though? Would the PSU market actually change for every unit to have a fanless mode or would it just be like a rule that's not really followed and all that junk will still be sold?

    It's more like when Haswell came out and introduced some new sleep states. There will be units that support it, but most of the budget offerings will not. Most that don't support the new spec will most likely advertise itself as ATX 12v 2.1 instead of whatever the new spec is going to be called.

    Why have a switch if the semi-fanless mode is the way to go? there must be a disadvantage; I imagine reduced lifetime.

    Some users do not feel comfortable with a semi-fanless mode, so they give you the option to have the fan going at all times.

    The general fear probably comes from the old troubleshooting adage of "Is the fan spinning?" to indicate if the device was at least partially functional.

    What Tator said.

    Even today, you have PSU's that come back from Intel's lab with FAIL on the report. Doesn't make them "illegal" to sell.

    But if you build/sell PCs in California, you need to meet the requirements. What's funny is you really can't do a "California version" of your build. Since the big builders will ship a container to Microcenter, Best Buy, Amazon, etc. and then those resellers ship the product back out to customers, the builder has no control over what goes where. They'll essentially have to make ALL of their PC's "CEC compliant" or risk the penalties of shipping a non-compliant product into the state. The only builders that are safe are the small ones. Like a small boutique in Texas with a local customer base.
