An All-White RTX 5090 Gaming PC for 4K
This RTX 5090 gaming PC Singapore build runs the Gigabyte RTX 5090 32 GB Aorus Master ICE and Intel Core Ultra 9 285K inside the Lian Li Lancool 207 White at SGD $12,450. The Lian Li Lancool 207 is a full-mesh mid-tower with a large interior and front-to-back airflow path, one of the few cases with enough interior depth for the RTX 5090 Aorus Master ICE at full card length. The all-white build theme runs from the case and AIO to the PSU and RAM sticks.
The Intel Core Ultra 9 285K is Intel's Arrow Lake flagship, 24 cores across 8 Performance-cores and 16 Efficient-cores. At 4K gaming, where the RTX 5090 carries nearly all rendering load, the 285K keeps CPU utilisation well below the GPU. The 64 GB DDR5 at 6000 MHz and 8 TB of Samsung 990 Pro NVMe storage (two 4 TB drives) cover both gaming and content creation workloads at the same time.

PERFORMANCE
4K Gaming at Maximum Settings
The RTX 5090 32 GB is Nvidia’s flagship gaming GPU and is built for high-end 4K workloads. In GamersNexus testing, it averaged 95 FPS in Cyberpunk 2077: Phantom Liberty at 4K raster and 53 FPS at 4K RT Ultra without upscaling. In GeekaWhat testing, an RTX 5090 averaged 293 FPS in Apex Legends at 4K High settings. GamersNexus also found the RTX 5090 to be 20-50% faster than the RTX 4090 in its 4K rasterization tests and around 27-35% faster in 4K ray-tracing workloads.
The Core Ultra 9 285K uses 24 cores, with 8 P-cores and 16 E-cores. In GamersNexus testing, it averaged around 104 FPS in Dragon’s Dogma 2, while higher-resolution 4K gaming generally shifts more of the workload onto the GPU. The 1650 W PSU in this build also provides substantial capacity above Gigabyte’s 1000 W recommended PSU specification for the AORUS RTX 5090 MASTER ICE.
"The 5090 outperforms the 4090 by 20-50% in our 4K rasterization tests and about 27-35% in our 4K ray tracing benchmarks."
