  • Power Usage (Mini)

    I dug up some information on power usage in different modes for the Mini Mac that others might find useful. Boyd Waters was kind enough to plug his power meter into his new Mini in different modes of operation. You can read the posting on this page (scroll down to Jan 25, heading Power Consumption).

    The short version is:
    • Off: 0-2 Watts
    • Booting: 30-40 Watts
    • Idle: 25 Watts
    • Sleep: 3-5 Watts (almost always 3)

    Again, further details are available in the original posting.

    That is so unbelievably low

    i thought it was around 85w for peak consumption
    I hope the mods don't realize I can still post.

      The power supply is rated to 85w, and the Apple Tech Specs say 85w max which is where everyone got that number. These are more usable numbers for predicting typical power consumption instead of just making sure you don't blow a fuse.

      P.S. alot of that 85W comes from meeting the requirements of supplying power to bus-powered USB and Firewire devices.

        Here's yet another tidbit.

        An Optima Yellow top (depending on model and voltage assumptions) has about 660 watt hours of energy. At a 3 watt drain that's a little over a week.

          These are very similar to the measurements I took directly at the Mac DC power input. Keep in mind you will be adding peripheral USB devices which may push this up substantially.

            Yea, and I know a few people who are planning on adding at least 2 external things (lets say a firewire drive, and usb2 gps). Mike will your powersource be similiar to the carnetix 1260? In that it works with the orig morex powerboard?

              Yes...similar concept. The P1900 will work with the existing 90W and 120W Morex PSUs in the Travla C137/138, IWill, EzGo, etc. Anything that needs +18V/19V/20V supply. Including the Mac Mini. It will also provide +12V to power your screen.

                Mike - when can we expect the power supply? I want to plan my Mac purchase around the release. Let us know. Thanks.

                  I can't really give you a date yet because of a number of variables.

                  However, the biggest concern is the lack of an appropriate Power connector and ACPI connector. If we can't identify these, you will have to:

                  1) Cut your power cable from your AC adapter and splice it to the P1900 (this is what I have done for testing...not recommended for the faint of heart).

                  OR

                  2) Solder power wires directly to the MacMini motherboard (very undesirable, but leaves your AC adapter intact).

                  the ACPI connector workaround is:

                  3) Solder two small (22GA) wires directly to your motherboard or in parallel with your power switch to allow the Startup/Shutdown controller to work.

                  I would much prefer to find a source of these connectors. But so far we've not been successful.

                    I know this is a dumb question, but have you tried asking Apple? Long shot, but might pan out.

                      Yes. Their Tech support doesn't even have information on the AC adapter yet. It's a bit too early for details to propagate thru the organizaiton.

                        I dunno. This doesn't sound too bad. I'd do it. The only reason I'd be buying the mini is to put it in my car. Considering all the hacking, soldering, and splicing I've done to my present PC, I'd have no hesitation cutting it.

                        What you could do to make it less traumatic to those who don't share my view is supply a nice looking quality plug and socket to allow you to switch between the car supply and the AC brick. That way cutting the power cord doesn't permanently disable the use of the computer on AC.

                          I have to disagree, I wouldnt want to cut the wire for the soul fact that I plan on taking the machine in the house every once in a while and I don't really wanna have to buy a replacement cable for it. hmm if only we could get something outta mac tec department for once.

                            I think this is what BugByte is saying. If you add a molex on both the cut-end of the AC brick and the same molex to the output cable of theP1900, the mating molex on the cut-off cable will fit either the AC brick (for inside use) or the P1900 (for in-car use).

                            Does this make sense?

                              I get ya! This would be something my uncle would be able to do in about 5 minutes, but thats because he has all the stuff and the experience to cut and add connectors and such, I don't think the average user is going to want to mess around with anything like that though. But that is one bridge almost crossed hehe.
