A single powerful +12V rail supports high-end component upgrades and overclocking. The unit also implements multiple advanced protections including over current, over power, over voltage, short circuit, under voltage and over temperature protection.
Suitable for (tasks / use cases)
High-performance desktop PCs with discrete graphics cards
Workstations and small servers requiring reliable, continuous power
Systems using ATX 3.0 / 12V-2x6 (12+4 pin) GPU connectors
Builds where compact size and tidy cable management are important
