This has been proven by a few people now that have documented their tests. Draw more than 210W and the Mac will shut down. To my knowledge, no-one has ever squeezed more than 210W out of a mini 6-pin connector. Mind you, this connector and others like it (Molex 39-01-2060) are rated for 600V at 9A so 12V at 9A should be very much possible without any issues for these connectors (using the appropriate gauge wiring of course). This is simply going off of the datasheet. 108W * 3 pins = 324W total available power for a mini 6-pin connector.This leaves us with the following conclusion: In the Mac Pro 4,1/5,1, this third pin is connected and provides 12V. The standard for this connector is that only two 12V pins are connected and a third is optional. This connector is rated at 9 Amps per contact (pin). The datasheet for that connector can be found on the linked page. This is what you’ll find on the cable connecting your GPU to one of the mini 6-pin auxiliary power connectors on the board. Presenting the “ Molex 45559-0002” connector. This counterpart does have specs available online.

But just like the mini-USB or mini-DVI, the mini 6-pin PCIe connector is just a smaller form factor of it’s full sized counterpart. connector housings’) has proven not possible for me. Here are my findings…Ĭlaim 1: The mini 6-pin connector can only provide up to 75W of powerįinding a spec sheet for the mini 6-pin (or ‘Molex Mini-Fit Jr. I’ve gathered all the relevant information and put the puzzle pieces together, along with anecdotal evidence from Mac Pro users in MacProUpgrade. I needed definitive proof (at least definitive for me) of these two claims so I decided to really dive into this. The traces in the Mac Pro’s logic board are too thin to have more power demanded than 75W. The mini 6-pin connector can only provide up to 75W of power.Ģ. A few things have bothered me about the reasons for recommending the Pixlas Mod.ġ.
