Compact gaming barebone for 1080p and 1440p

The Rmatamini P99S is a pre-built 5.6L mini PC that ships fully assembled with Windows 11 and a Linux gaming OS ready to boot. An Intel Core i5 14400F processor with 10 cores handles multithreaded workloads while an RX 5500 graphics card with 8 GB of video memory drives smooth frame rates at 1080p and 1440p resolutions. Dual-channel DDR4 memory and a 512 GB NVMe SSD keep boot and load times short.

16 GB DDR4 and 512 GB NVMe with expansion headroom

Sixteen gigabytes of DDR4 2133 dual-channel RAM and a 512 GB PCIe NVMe SSD provide enough capacity for modern games and multitasking without bottlenecks. The chassis supports further RAM and storage upgrades so you can add memory or a larger drive when your library grows. Integrated Wi-Fi 5 and Bluetooth 5.2 handle wireless peripherals and streaming without extra adapters.

RX 5500 8 GB GPU decides 1080p and 1440p suitability

The dedicated RX 5500 with 8 GB of graphics memory is the single component that determines whether this system meets your performance target. It delivers playable frame rates at 1080p and 1440p in current titles but will run out of headroom for 4K gaming or heavy ray-tracing workloads. Buyers who need 4K output or higher VRAM should look elsewhere.

Questions about this item

Will my existing DDR4 2133 memory modules work with the 16GB already installed in this P99S?

Yes, the board supports dual-channel DDR4 2133 so your current sticks will run alongside the factory 16GB at the same speed.

How can I confirm the RX 5500 8GB graphics and Core i5 14400F are performing correctly after first boot?

Open Task Manager or GPU-Z to verify the RX 5500 shows 8GB VRAM and the CPU reports 10 cores at 2.5 GHz base clock.

Which cables and peripherals are included in the box and what must I provide separately?

The unit ships fully assembled with Windows 11 and Linux gaming OS pre-installed; you only need to supply a monitor, keyboard, mouse and power cord.
