Thermaltake Smart Series 600W power supply PS-SPD-0600NPCWUS-W

Smart Series 600W overview

The Thermaltake Smart Series 600W is a non-modular ATX 12V v2.3 power supply built for mainstream desktop builds. It carries 80 PLUS certification and active PFC, delivering up to 86 percent efficiency across typical loads. A single +12V rail rated at 45A provides stable power for graphics cards and CPUs. The unit includes two 6+2-pin PCIe connectors and six SATA power connectors for drives and peripherals.

Capacity and headroom

At 600 W maximum output the supply handles mid-range gaming systems and workstations with a single high-end GPU. The 82 to 86 percent efficiency range at 20 to 100 percent load keeps waste heat low under normal use. Hold-up time is 16 ms at 60 percent load, giving a brief ride-through during short power interruptions. Continuous loads near the 600 W limit will push the 120 mm intelligent fan to higher speeds.

ATX 12V v2.3 interface limits

The ATX 12V v2.3 design tops out at 600 W, so dual-GPU configurations or extreme overclocks may exceed its capability. Non-modular cabling means all leads remain in the case, which can restrict airflow in compact chassis. The 140 mm length fits most standard ATX cases but may not suit small-form-factor builds. Efficiency is certified to the base 80 PLUS level, not the higher Bronze, Silver or Gold tiers.
