1U rackmount chassis Supermicro CSE-PT17L — supports ATX power supply, slim server enclosure

Supermicro CSE-PT17L is a 1U rackmount chassis engineered for compact server deployments where a low-profile enclosure and compatibility with standard ATX power supplies are required. The slim server enclosure accepts full‑size ATX power units and provides a space-efficient platform for building rack-mounted systems used in data centers, edge computing, and network infrastructure. The design focuses on maximizing internal usable volume within a 1U height while maintaining compatibility with common server components.

Advantages

The 1U rackmount chassis supports standard ATX power supplies, simplifying component sourcing and replacement. Its slim form factor enables dense rack population and can reduce overall rack depth requirements. The enclosure is constructed to fit typical server racks and mounting rails, offering straightforward integration into existing rack systems. The internal layout is optimized for airflow and cable routing within the constrained 1U height.

Suitable for

• Compact rack servers for data center or colocation environments
• Edge servers and remote network appliances with space constraints
• Network equipment housings and firewall or gateway appliances
• Custom 1U builds that require a standard ATX power supply

Key specifications

• Form factor: 1U rackmount chassis
• Power supply compatibility: standard ATX power supply (internal)
• Chassis type: slim server enclosure for 19-inch racks
• Internal space optimized for low-profile components and cable routing
• Front and rear panel layout suitable for typical server I/O and drive placements

How to use

Install the chassis into a compatible 19-inch rack using the provided mounting points or rail kit. Fit a standard ATX power supply inside the designated internal compartment and secure it according to the chassis mounting holes. Populate the internal motherboard and expansion components that fit within the 1U profile, taking care to route power and data cables to avoid airflow obstructions. Connect front and rear I/O panels as required and verify all internal connections before powering the system.

Usage recommendations

For reliable operation, use an ATX power supply with sufficient wattage and proper cooling for the intended server workload. Ensure adequate rack airflow and leave clearance above and below the chassis if possible. When populating with high‑power components, verify thermal limits and choose components with low-profile cooling solutions compatible with 1U height.
