The Noctua x ProArt Custom PC Build
This custom PC build in Singapore is a collector's assembly. The customer brought their own ASUS GeForce RTX 5080 Noctua OC Edition 16 GB, Noctua NH-D15 G2 air cooler, ASUS ProArt PA602 Wood Edition case, Seasonic PRIME TX-1600 Noctua Edition (1600 W, 80+ Titanium) power supply, and TEAMGROUP T-Create Classic DDR5 memory. Mansa supplied the ASUS ProArt X870E-CREATOR WIFI motherboard, AMD Ryzen 7 9800X3D, and Lexar NM790 4 TB Gen 4 NVMe SSD, then assembled the full system. The total for new components and building service was SGD 2,584.
The RTX 5080 Noctua OC Edition is a limited ASUS and Noctua collaboration that matches the case and cooler's brown-and-beige colour scheme. The ProArt X870E-CREATOR WIFI is a top-tier AM5 board with PCIe 5.0, Wi-Fi 7, and USB4. The NM790 gives fast Gen 4 storage on a single large drive.
The 168 mm NH-D15 G2 fits easily inside the PA602's roomy interior. With no liquid cooling at all, it keeps the Ryzen 7 9800X3D cool without radiators or tubes.
Mansa's building service covers cable routing, installation, BIOS update, and stress testing. Customers bringing their own parts can start a build from SGD 120, with the final fee based on complexity.

PERFORMANCE
What Can This PC Do?
The Nvidia RTX 5080 16 GB averaged 112 FPS in Final Fantasy XIV at 4K, 81 FPS in Dying Light 2 at 4K, and 58 FPS in Black Myth: Wukong at 4K rasterized, per GamersNexus. At 1440p, all three titles run at considerably higher frame rates, and the RTX 5080 16 GB VRAM avoids texture memory limits at both resolutions.
The Ryzen 7 9800X3D's 96 MB L3 cache via AMD's 3D V-Cache technology keeps frame-time variance low in CPU-sensitive titles, which is more noticeable at 1440p where the GPU is less of a constraint than at 4K. The ASUS ProArt X870E-Creator WIFI motherboard supports PCIe 5.0 for the Lexar NM790 4 TB SSD, which saturates that bandwidth at sequential read speeds above 12,000 MB/s.
"The Ryzen 7 9800X3D is the fastest gaming chip on the market by a large margin."
