The TR2 Bronze is the latest mainstream power supply series from Thermaltake, with the 80 Plus Bronze certification and available in 380 W, 450 W, 500 W, 600 W, 700 W, and 800 W versions. (Not all versions are available on all markets.) It is important to understand that Thermaltake still has some low-end power supplies labeled as TR2, with lower efficiency. Why a manufacturer keeps using the same name for different products is beyond us. We are reviewing the 700 W model of the “new” TR2 series, a.k.a. the TR2 Bronze.
The Thermaltake TR2 700 W is manufactured by FSP; it is actually a rebranded FSP700-80GHN(85) unit, which is also sold as the FSP Epsilon 85 Plus 700.
The Thermaltake TR2 700 W is 5.5” (140 mm) deep, using a 120 mm sleeve bearing fan on its bottom (Thermaltake TT-1225, which is actually manufactured by Yate Loon).
This unit doesn’t have a modular cabling system. All cables are protected with nylon sleeves, which come from inside the unit. This power supply comes with the following cables:
- Main motherboard cable with a 24-pin connector, 22” (56 cm) long
- One cable with two ATX12V connectors that together form an EPS12V connector, 21.6” (55 cm) long
- Two cables, each with two six/eight-pin connectors for video cards, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with four SATA power connectors, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with three SATA power connectors, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with four standard peripheral power connectors, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with three standard peripheral power connectors and one floppy disk drive power connector, 19.7” (50 cm) to the first connector, 5.9” (15 cm) between connectors
All wires are 18 AWG, which is the minimum recommended gauge.
The cable configuration is adequate for a mainstream 700 W power supply, with four video card power connectors and seven SATA power connectors.
