00:00:01,100 --> 00:00:09,766

Hello everyone, today we are going to learn about the Apple mainboards A1418, A1419, A1481

2

00:00:14,600 --> 00:00:20,033

A1418, A1419 and A1481 are all desktop machines,

3

00:00:20,900 --> 00:00:27,233

among which A1418 and A1419 are all-in-one machines with display screens

4

00:00:29,133 --> 00:00:33,200

This is the inside of the A1418 with the screen removed

5

00:00:35,133 --> 00:00:40,633

As we can see, it has a fan, it has a hard drive, it has a power board

6

00:00:41,766 --> 00:00:45,333

This is its mainboard, and this is its speakers

7

00:00:46,266 --> 00:00:47,966

After we took out the mainboard,

8

00:00:48,333 --> 00:00:53,866

It can be seen that the CPU seat used by this mainboard is the desktop CPU seat,

9

00:00:54,800 --> 00:00:56,700

which is a high-power CPU

10

00:00:56,866 --> 00:01:01,066

Next to it is a GPU, or independent graphics card,

11

00:01:02,300 --> 00:01:04,966

with two graphics memory chips next to it

12

00:01:05,400 --> 00:01:06,966

This is the PCH

13

00:01:08,833 --> 00:01:13,233

This is the memory slot, and there's a SATA port next to it,

14

00:01:13,966 --> 00:01:15,800

and the power supply for the hard disk

15

00:01:19,266 --> 00:01:21,733

This is the main power input to the mainboard,

16

00:01:22,400 --> 00:01:25,900

the input to the main power supply that this power board provides

17

00:01:26,800 --> 00:01:29,800

There's a WIFI/ Bluetooth slot next to it

18

00:01:31,500 --> 00:01:34,566

These surrounding inductors are powering the CPU,

19

00:01:34,966 --> 00:01:38,066

and this inductor is powering the graphics card

20

00:01:39,766 --> 00:01:41,733

This mainboard interface is rich,

21

00:01:42,500 --> 00:01:48,800

there are network cable interface, DP interface, USB interface, and so on

22

00:01:50,166 --> 00:01:53,433

On the back of the mainboard, there is a lightning chip,

23

00:01:54,033 --> 00:01:56,766

which is responsible for the lightning interface

24

00:01:57,966 --> 00:01:59,833

There's an EC up here

25

00:02:02,533 --> 00:02:04,866

Well, that's basically how it's structured

26

00:02:05,766 --> 00:02:11,133

There are two ports on the top, and these are the screen ports that connect the screen cables

27

00:02:11,700 --> 00:02:15,000

This is the mainboard of the A1419 all-in-one

28

00:02:19,400 --> 00:02:23,633

We didn't take the heat sink off, so this is the video card,

29

00:02:27,766 --> 00:02:30,200

and underneath this is the CPU,

30

00:02:32,333 --> 00:02:34,533

and next to the CPU is the memory

31

00:02:35,233 --> 00:02:37,033

This is a PCH

32

00:02:37,766 --> 00:02:41,800

It uses the same CPU seat as the A1418

33

00:02:44,933 --> 00:02:47,733

This bottom is the bracket for the radiator

34

00:02:50,500 --> 00:02:53,100

There's a slot for a solid state drive

35

00:02:59,533 --> 00:03:02,466

This mainboard interface is also relatively rich

36

00:03:03,066 --> 00:03:07,066

The lightning chip specializes in managing the lightning port next to it

37

00:03:07,633 --> 00:03:10,333

This is the mainboard A1419

38

00:03:12,066 --> 00:03:13,300

It's a desktop

39

00:03:14,433 --> 00:03:17,833

It's just a mainframe, it doesn't have a display

40

00:03:19,866 --> 00:03:22,066

This one belongs to the Mac Pro series,

41

00:03:22,733 --> 00:03:24,733

which is Apple's high-end model

42

00:03:30,700 --> 00:03:32,966

There are two mainboards for the CPU

43

00:03:34,566 --> 00:03:37,033

You can see the memory slot on the side,

44

00:03:37,366 --> 00:03:40,866

as well as the power port and some peripheral ports

45

00:03:41,733 --> 00:03:49,233

For example, DP lightning port, USB port, Type-C port, and so on

46

00:03:52,666 --> 00:03:54,800

The power button is back here, too

47

00:03:55,433 --> 00:03:59,066

At the bottom of it is a board called the PCH board

48

00:04:00,200 --> 00:04:04,066

The two pins on the side are connected to the two CPU mainboards

49

00:04:08,066 --> 00:04:12,466

Because it's connected to 220 volts of alternating current,

50

00:04:12,866 --> 00:04:14,633

there's a power board inside

51

00:04:16,000 --> 00:04:18,866

This power board is also plugged into this slot
