Core i5-13400TEF barebone mini PC

This Rmatamini P99S barebone mini PC integrates an Intel Core i5-13400TEF processor with a discrete graphics card providing 4 GB of video memory. The system ships with Windows 11, 8 GB of DDR4 memory at 2666 MHz, and a 256 GB NVMe drive. Its 7.8 L chassis is designed for space-saving setups and portable use.

Suited for compact productivity and light gaming

The configuration handles office applications, high-definition video editing, casual games and multitasking in a small footprint. Buyers who need more than 8 GB of system memory, larger internal storage, or a higher-tier graphics card for demanding titles should look at a different platform.

Discrete GPU with 4 GB video memory

The installed graphics card delivers 4 GB of dedicated video memory, which is the key specification for entry-level gaming and hardware-accelerated creative workloads. This amount of VRAM determines the texture quality and resolution levels the system can sustain.

Questions about this item

How do I install the DDR4 memory and what step is often missed?

Open the chassis, align the DDR4 SO-DIMM at 2666 MHz with the slot, press until the clips lock, then verify 8 GB appears in BIOS before closing the case.

Which component will need maintenance or replacement first?

The power supply is a used and modified unit, so its capacitors or fan are the most likely parts to require service before the new CPU or DDR4 memory.

What limit appears first during sustained heavy workloads?

The 7.8 L chassis and upgraded cooler set the thermal ceiling; the Core i5-13400TEF will throttle once its temperature target is reached.
