500 W ATX power supply for mainstream builds

This Thermaltake Smart unit delivers 500 W of continuous power through a single +12 V rail rated at 35 A. It meets Intel ATX 12V 2.31 and EPS 12V 2.92 specifications and carries 80 PLUS certification for 80 % typical efficiency. The supply is Haswell ready and supports SLI or CrossFire multi-GPU configurations.

Hardlined cables with a 120 mm intelligent fan

All leads are fixed, including a 20+4 pin main connector, two 6+2 pin PCIe plugs and six SATA power connectors. A 120 mm fan provides airflow while the active PFC circuit corrects the power factor across a 100–240 V input range. The chassis measures 140 mm in depth, fitting standard ATX cases.

Single-rail design and hold-up time define

The single +12 V rail simplifies load balancing but caps combined 12 V current at 35 A. Hold-up time is specified at 16.6 ms minimum and the power-good signal arrives within 100–500 ms. Efficiency peaks at 86 % under typical loads, so sustained draws near 500 W will generate more heat and fan noise.
