## Description

Add modern, reliable graphics to compact and small-form-factor systems with the **HP AMD Radeon RX 6400**. Built on AMD’s **RDNA™ 2** architecture with **4GB of GDDR6** memory, this low-profile, single-slot card delivers smooth 1080p productivity and light gaming while drawing just **53 watts** — entirely from the PCIe slot, with **no supplementary power connector required**.

A full-length aluminum heatsink paired with a single low-noise fan keeps the card cool and quiet, and the low-profile board fits both small-form-factor and standard desktops. Choose your **PCIe bracket at checkout** — low-profile, full-height (tall), or both — so it drops straight into HP and other SFF machines as easily as a full-size ATX tower.

Dual digital outputs — **1× DisplayPort 1.4** and **1× HDMI 2.1** — drive two high-resolution displays for office, point-of-sale, digital-signage, and home-theater builds. Hardware **H.264 and H.265 (HEVC) decoding** keeps everyday video playback smooth and efficient. (Note: the Navi 24 media engine does not include hardware video encoding or AV1 decode.)

This is a **brand-new OEM unit** (HP spare **M99977-001**) in bulk packaging — no retail box.
