4K Gaming PC Build with RTX 4090 and Ryzen 9800X3D CPU
Hi everyone, and thank you for checking out my post about my current gaming rig.
Ryzen 7 9800X3D (8-core)
This is a powerful CPU featuring an updated implementation of 3D V-Cache, which significantly enhances gaming performance—especially at lower resolutions and in those critical 1% lows—for smoother overall gameplay.
Although the cache is less impactful at 4K resolution (where the GPU becomes the bottleneck), enabling Precision Boost Overdrive (PBO) in the BIOS can still improve performance and operating characteristics for those who like to tweak their system.
MSI RTX 4090 Suprim X
This high-performance GPU with 24GB of VRAM can handle massive texture packs and demanding games without issue. It has been running cool and reliably for over two years now, though it’s due for a repaste and fresh thermal pads.
ASUS B650E-E ATX
This board offers enough VRM to support high-end CPUs, including 16-core models. It also includes a built-in mini fan in the heatsink, a variety of ports and expansion slots, and an onboard error code display for quick troubleshooting.
The GPU quick-release button was a standout feature and helped seal the deal for me.
32GB (2x16) G.Skill Trident Z5 Neo RGB 6400Mts cl30
Fast and stylish DDR5 RAM with EXPO support for a smooth plug-and-play experience. The sleek RGB lighting adds a nice touch, and the 32GB capacity is more than enough for 4K gaming and multitasking. No tweaking needed—just enable EXPO and you're good to go!
Cooler Master MWE Gold 1250 V2 - ATX 3.0
A robust and future-proof power supply with a dedicated 12V 16-pin high-power connector. It provides ample wattage for this build and beyond.
2 × Samsung 980 PRO 1TB
Fast and reliable. One drive has been in use for two years, the other for about one year. Both are performing without issues.
BeQuiet! Silent Base 802 Black
A spacious and builder-friendly case with room for even the largest GPUs (four-slot width). It supports 420mm AIO radiators in both the front and top, giving it exceptional flexibility for cooling setups.
I filled it with 140mm fans wherever possible. It’s heavy, but absolutely worth it for the airflow and ease of upgrades.
NZXT Kraken Z63 (280mm AIO)
This cooler has served me well for almost four years, and it continues to deliver excellent thermal performance. It's more than sufficient for the CPU, even under load.
Lian Li UNI FAN SL-INF 140 RGB
I replaced the standard AIO fans with matching Lian Li fans to maintain a consistent look and airflow. The case currently holds a total of nine 140mm fans.
I even managed to fit two additional 140mm Corsair fans at the bottom for extra intake airflow.
Building this PC was a lot of fun. Despite the number of fans, the system remains quiet and delivers strong cooling performance. It should serve me well for years to come, and the spacious case makes future upgrades simple and convenient.
