Hello everyone, in this lesson, we will take the drawing of the 5700XT graphics card as an example

2

00:00:07,400 --> 00:00:11,066

to explain the timing sequence of the A card after the 5000 series

3

00:00:11,533 --> 00:00:16,766

The first step in the work of the graphics card must have an input voltage

4

00:00:18,100 --> 00:00:25,400

The input voltage here includes gold finger 12V, gold finger 3V and power interface 12V

5

00:00:25,800 --> 00:00:29,933

Let's find these power supplies in the drawings of 5700XT

6

00:00:31,200 --> 00:00:34,400

We open the drawing and find the directory

7

00:00:34,933 --> 00:00:38,500

You can see that the second page is the PCIE interface

8

00:00:38,666 --> 00:00:44,166

Jump to the second page and find the PCIE interface

9

00:00:44,166 --> 00:00:52,600

Then we found the two input voltages of the golden finger, +12V_BUS and +3V3_BUS

10

00:00:52,866 --> 00:00:55,733

Let's draw these two first

11

00:00:59,966 --> 00:01:06,066

After finding all the golden finger power supply, let's take a look at the power supply of the power interface

12

00:01:06,400 --> 00:01:09,700

We find the power interface in the bitmap

13

00:01:10,500 --> 00:01:14,800

Find the power interface in the drawing through the point map

14

00:01:15,333 --> 00:01:21,333

It can be seen that the power supply names of the two power ports of this graphics card are different.

15

00:01:22,166 --> 00:01:26,933

The name of the power supply output by the above power interface is _A

16

00:01:27,233 --> 00:01:32,233

The name of the power supply output by the following power interface is _B

17

00:01:32,666 --> 00:01:35,700

Let's draw these two next

18

00:01:39,400 --> 00:01:44,366

So far, even if all the input power supply of the graphics card is available
