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.

Questions about this item

Will the 600 W unit power a graphics card that needs two 8-pin connectors?

The supply includes two 6+2-pin PCIe cables, so each can serve as a 6-pin or an 8-pin connector for SLI or CrossFire configurations.

Is the 140 mm depth compatible with a standard mid-tower case?

At 140 mm long, the unit fits most ATX cases, but verify your case’s maximum PSU length before ordering.

What does the 80 PLUS rating mean for daily electricity use?

Efficiency reaches 82 to 86 percent from 20 to 100 percent load, reducing wasted power and heat compared with non-certified units.
