Power supply INTER-TECH SAMA XPH-1200A 1200W ATX 3.0

INTER-TECH SAMA XPH-1200A 1200W ATX 3.0 is a desktop power supply engineered for systems that require stable, continuous power delivery. Designed to meet ATX 3.0 standards, this 1200W unit supports modern high-performance components and multi-GPU or workstation configurations. The power supply provides the necessary rails and connectors for contemporary motherboards, processors and graphics cards while prioritizing consistent voltage output and thermal management.

Advantages

The unit supplies up to 1200 watts of continuous power with ATX 3.0 compatibility, offering headroom for power-hungry components and expansion. Built to deliver stable voltages, it reduces the risk of system instability under sustained load. Thermal and electrical protections are included to protect connected hardware from common faults. The form factor and connector set are suitable for standard ATX cases and modern component layouts.

Suitable for

• Gaming PCs with high-performance CPUs and GPUs
• Workstations for content creation, rendering and CAD
• Multi-GPU or multi-drive system configurations
• System builders assembling ATX 3.0-compatible desktop systems

Key specifications

• Maximum output power: 1200 W continuous
• Form factor: ATX 3.0-compatible power supply
• Output rails: multiple DC rails providing required voltages for motherboard, CPU and GPUs
• Cooling: integrated fan for active thermal management
• Protections: over-voltage, under-voltage, over-current and short-circuit protection
• Connector types: standard ATX motherboard connector and multiple PCIe/CPU peripheral connectors suitable for modern components

How to use

Install the power supply into a compatible ATX case, aligning the mounting holes and securing the unit with appropriate screws. Connect the main 24-pin motherboard cable, CPU power cable(s) and required PCIe power connectors to graphics cards. Attach storage and peripheral power cables as needed. Ensure proper cable routing to maintain airflow and prevent obstruction of fans. Confirm that the case front and rear cooling are adequate for the system’s thermal load before powering on.

Recommendations

Verify component power requirements and plan cable connections before installation. Use a case with sufficient airflow and maintain regular dust cleaning to preserve cooling performance. For systems with multiple high-power GPUs or frequent heavy loads, monitor voltages and temperatures during initial use to confirm stable operation.
