Graphics card Alphacool ES RTX 5090 Reference 1‑Slot Design REV1

The Alphacool ES RTX 5090 Reference 1‑Slot Design REV1 is a single‑slot graphics card built around the RTX 5090 platform, intended for systems where space is limited. This compact reference‑style board provides the core functionality of the RTX 5090 series in a reduced physical footprint, enabling installation in tight cases, compact workstations, or small form factor PCIe configurations while maintaining compatibility with standard PCIe slots.

Advantages

The one‑slot design minimizes occupied expansion space, making the card suitable for enclosures with restricted clearance. As a reference REV1 model, it follows a standardized layout for straightforward integration into systems designed for RTX 5090 platform cards. The compact size facilitates airflow planning in confined chassis and simplifies installation in builds that cannot accommodate dual‑slot or larger cooling solutions.

Suitable for

• Compact workstations where PCIe slot space is limited
• Small form factor or mini‑ITX systems with single‑slot constraints
• Systems requiring a standard reference layout for compatibility with existing components

Key specifications

• Form factor: single‑slot (1‑slot) reference design
• Platform compatibility: RTX 5090 series
• Interface: standard PCIe slot compatibility
• Manufacturer: Alphacool
• Model designation: REV1

How to use

Power off the system and disconnect all power sources before installation. Remove the appropriate slot cover on the chassis, align the card with a free PCIe slot and seat it firmly into the slot. Secure the card as needed according to the chassis design, taking into account the single‑slot width. Reconnect system power and install or update device drivers and firmware compatible with the RTX 5090 platform following the operating system and motherboard vendor instructions.

Recommendations

Ensure the case provides adequate airflow around the single‑slot card and verify clearance for adjacent components. Use up‑to‑date RTX 5090 drivers and follow motherboard guidelines for PCIe lane allocation to achieve stable operation.
