Power Supply Unit Thermaltake Litepower GEN2 550W

The Thermaltake Litepower GEN2 550W is an ATX power supply unit designed for basic desktop PCs that require reliable, efficient and quiet operation. Compliant with the ATX 12V V2.3 standard, this black 550 W PSU includes a dedicated +12V rail and a 24-pin ATX motherboard connector. It accepts 230 V AC at 50–60 Hz, features a 120 mm cooling fan and standard cable lengths (motherboard cable 45 cm, SATA cable 450 mm), providing stable power delivery for mainstream components.

Advantages

The Litepower GEN2 550W combines industry-standard compatibility with built-in protections — over voltage, over power and short-circuit protection — to help safeguard connected components. Its dedicated +12V rail and ATX 12V V2.3 compliance ensure compatibility with current desktop hardware, while the active cooling with a 120 mm fan supports quiet, continuous operation. The unit’s black ATX form factor and common cable lengths make installation straightforward in most standard PC cases.

How to use

Install the PSU into a compatible ATX case following standard safety procedures: disconnect mains power, secure the unit to the case with screws, connect the 24-pin ATX cable to the motherboard and attach SATA/Molex connectors to drives as required. Ensure the PSU fan intake and exhaust are not obstructed and that cable routing allows proper airflow. Reconnect mains power and verify system boots before regular use.

Recommendations

Use the Thermaltake Litepower GEN2 550W in systems whose combined component power draw does not exceed the unit’s rated output; leave adequate airflow around the PSU and avoid placing the system in excessively dusty or humid environments. For systems with high-end GPUs or heavy overclocking, consider a higher-capacity PSU.
