Compact Radeon RX 6400 for small builds

The MSI RX 6400 AERO ITX 4G is a single-fan graphics card built for small form factor systems and HTPC cases. It delivers a game clock of 2039 MHz and a boost clock of 2321 MHz through 768 stream processors. The 4GB GDDR6 frame buffer runs on a 64-bit interface at 16 Gbps. Display outputs include one HDMI 2.1 and one DisplayPort 1.4a supporting up to 7680 x 4320 resolution.

Upgrade from integrated graphics on PCIe 4.0

This card replaces a CPU integrated graphics solution when a discrete GPU is required for multi-monitor productivity or entry 1080p gaming. The PCI Express 4.0 x4 interface provides full bandwidth on compatible platforms while the 53W thermal design power only needs a 350W power supply. The jump is worth it when your motherboard lacks video outputs or when hardware decode for modern codecs is needed.

Steady 53W load with copper heatpipe cooling

Under sustained load the single fan and copper heatpipe cooler keeps the GPU at its rated 53W thermal design power without throttling. The custom fan curve is tuned for consistent airflow rather than brief burst performance. Afterburner OC Scanner can find the highest stable overclock within the same power envelope for users who want extra headroom.

Questions about this item

What clearance does the single-fan ITX card need inside a small-form-factor case?

The compact single-fan design fits small-form-factor systems and HTPC builds without requiring extra length or height clearance.

Which power connector must be plugged in during installation, and what PSU rating is recommended?

A 350 W PSU is recommended for the 53 W board; connect the required PCIe power cable before securing the card.

When should the thermal paste under the copper heatpipes be refreshed?

Refresh the paste if GPU temperatures rise noticeably after extended use; the copper heatpipes transfer heat from the baseplate to the heatsink.
