For closer and thorough look, lets removed the heatsinks.
- 1 x 4-pin CPU fan connector (RED)
- 1 x 4-pin water-pump-fan connector (BLUE)
- 4 x 4-pin system fan connectors (YELLOW)
- 2 x 5050 RGB 4-pin 12V connectors (GREEN)
- 1 x WS2812B Individually Addressable RGB 3-pin 5V connector (PINK)
- 1 x CORSAIR connector JCORSAIR1 (PURPLE)
With heatsink removed, we can see the VRM MOSFETs and 5×2 phase design with highside 4C029N MOSFET, and lowside MOSFET 4C024N Coupled with Black polymer capacitors and IOR 35201 dual output digital multi-phase controller completes the CPU VCC and 2 phase for SoC VCC. all of which are powered by two 8-pin connectors, though you don’t need both connectors, as from our testing the X470 Gaming Pro Carbon AC 100% functional with just one connector even with Overclocking. But you need to connect the first 8-pin connector (CPU_PWR1) not the second one.
Without the PCH heatsink, we can see the small AMD X470 chipset, along with a couple of ASMedia ASM1480, which is an 8 channel multiplexer that allows quick switching for high speed, high bandwidth differential protocols.
As we can see MSI using a Realtek ALC1220 audio codec with Gold series Nippon-Chemicon audio capacitors and offers 120dB output. MSI adds in a Texas Instruments OP1652 operational amplifier for the front headphone outputs. All of which is placed in separated layers in the PCB ensures equally pristine sound quality for both left and right audio channels. The amplifier can power headphones up to 600Ω impedance.
