The Smart Series is a new entry-level power supply series from Thermaltake, with the standard 80 Plus certification. Coming to replace the old Purepower and TR2 “standard” series, this new series features 430 W, 530 W, 630 W, and 730 W models, all with the standard 80 Plus certification. Let’s see if the 630 W model is a good choice.

The new Smart Series power supplies are manufactured by HEC/Compucase, just like the old Purepower models. Apparently, the Smart Series is derived from HEC’s TB series.

The Thermaltake Smart 630 W is 5.5” (140 mm) deep, using a 120 mm sleeve bearing fan on its bottom (Thermaltake TT-1225A, which is actually manufactured by Young Lin Tech).

This unit doesn’t have a modular cabling system, and only the main motherboard cable uses a nylon sleeve, which comes from inside the unit. This power supply comes with the following cables:

• Main motherboard cable with a 20/24-pin connector, 22” (56 cm) long
• One cable with two ATX12V connectors that together form an EPS12V connector, 22” (56 cm) long
• One cable with two six/eight-pin connectors for video cards, 17.7” (45 cm) to the first connector, 5.9” (15 cm) between connectors
• Two cables, each with three SATA power connectors, 19.3” (49 cm) to the first connector, 5.9” (15 cm) between connectors
• One cable with four standard peripheral power connectors and one floppy disk drive power connector, 18.9” (48 cm) to the first connector, 5.9” (15 cm) between connectors

All wires are 18 AWG wires, which is the minimum recommended gauge.

The cable configuration is excellent for an entry-level 630 W power supply.
