So the latter will be throttled to maintain the power balance. The 60W supply, even if connected to a 17 inch MBP, will satisfy all internal and external loads (USB, FW, drives, screen), except for the CPU and GPU. The CPU load shedding will, by design, always manage to balance the power.

If there isn't enough power for the machine, the load shedding kicks in and throttles the CPU (and perhaps GPU - I don't recall offhand). Conversely, a fully charged battery will demand a zero charger load, and that's fine. If there isn't enough power left for the charger, the battery is by definition discharging unless it has no charge left. Thus, given an available input power, the machine load is satisfied first, and any leftover power is provided to the battery charger. The power management system also knows the electronic nameplate of the power supply and thus its rated power. The loads are prioritized: the machine has priority over the battery charger.

The power management must maintain the following inequality balanced, in terms of power: (power adapter + battery as a power source) >= (battery charger + the machine). The battery as a power source is exclusive of the battery charger: a battery may operate as a power source, or the battery charger may operate, but never both at once. the machine (logic, drives, memory, screen, speakers, USB devices, etc.)Д«oth loads are adjustable and the power management's function is to adjust them as needed.The below explains why.ДЄ MacBook's power management works very simply: it maintains a balance of power between the power consumed by the loads and the power available from the sources. It will operate safely, but the CPU performance will be diminshed. The MacBook it's plugged into won't operate in a 'brownout'.

It will clearly run at full capacity for longer than a higher wattage adapter or even fail to keep up with the energy demands of a machine using more than 60w giving you a flat battery if you run a deficit of energy вЂњwhile chargingвЂќ. So no, a 60W adapter won't overheat when connected to a machine that needs an 85W adapter. This is a given for the systems to receive safety certifications. I will give some facts along with my reasoning.ДЄll MagSafe adapters, when plugged into a mechanically matching receptacle on a MacBook/MacBook Pro, are designed to run safely. The new 14- and 16-inch MacBook Pros start at $1,999 and $2,499 and will be available on Tuesday (October 26), but you can preorder them now from Apple's website.Д¬lick here to read about why Apple ultimately chose to make the new MacBooks bigger and heavier.There is a lot of misinformation in some answers. The 14-inch MacBook Pro comes with either a 67-watt (for the M1 Pro with 8-core CPU model) or 96-watt power adapter (for the other M1 Pro or M1 Max models), while the 16-inch MacBook Pro requires you to use Apple's brand new 140-watt USB-C power adapter, which happens to be the most powerful adapter that it has ever made. The catch with these fast charging speeds over MagSafe 3 is that you have to use the USB-C power adapter (or one that's more powerful) that Apple includes in the box. It will be able to juice the new MacBook Pros from zero to 50 percent battery in just 30 minutes. Apple hasn't detailed the exact differences in charging speeds when using USB-C (Thunderbolt 4) compared to MagSafe 3 just yet, but it has said that using the MagSafe connector is faster.
