1 Motherboard Prep PRO TIP

Before installing anything, update your MSI X670E Carbon BIOS. The 9800X3D is a new chip and the board needs to "learn" how to talk to it.

Do this before putting the CPU in the socket!

2 CPU & RAM Install

Gently place the Ryzen 7 9800X3D into the AM5 socket. Match the gold triangle on the chip with the triangle on the socket. Then, click your 32GB Corsair Vengeance DDR5 into slots 2 and 4.

3 Thermal Paste Application FIRST BUILD ESSENTIAL

Thermal paste helps transfer heat from the CPU to the cooler. Too little = overheating. Too much = messy (but usually harmless). For your Ryzen 7 9800X3D (square IHS), the easiest and most reliable method for beginners is the pea-sized dot.

Work on a clean surface. Less is usually better than more on modern CPUs.

4 Storage & Cooling

Install the Samsung 990 Evo Plus SSD under the primary M.2 heatsink. Then, mount the NZXT Kraken Elite 360. This "All-in-One" cooler keeps that high-end CPU frosty while looking amazing.

5 Case & Power

The HYTE Y70 is a showcase case! Mount the motherboard inside and slide in the Corsair RM1000x. Use the vertical riser cable included with the case for that "floating" GPU look.

6 The GPU & 12VHPWR CRITICAL

Install the ASUS ROG Strix 4080 vertically. Because this is a high-power card, the power cable (12VHPWR) MUST be pushed in until it clicks. If you see a gap, it's not safe!

Ensure the cable is not bent sharply right at the connector!
