TR2 is a cost-effective power supply series from Thermaltake, which is comprised of two sub-series: TR2 standard (430 W, 500 W, 600 W, 700 W and 1,000 W) and TR2 RX (450 W, 550 W, 650 W, 750 W, 850 W, 1,000 W and 1,200 W). Models from TR2 RX series have modular cabling system. Being targeted to users on budget, several model from this series don’t even have the standard 80 Plus certification. Today we are going to test the 750 W from TR2 RX series. Is it a good buy? Let’s see.

Thermaltake TR2 RX 750 W is 6 19/64” (16 cm) deep, using a 140-mm fan on its bottom and active PFC circuit, of course.

The reviewed power supply features a modular cabling system with six connectors (two red for video cards and four black for peripheral and SATA connectors), with four cables permanently attached to the power supply. These cables have nylon sleevings that come from inside the power supply unit.

The cables included are:

• Main motherboard cable with a 24-pin connector (no 20-pin option, permanently attached to the power supply).
• One cable with two ATX12V connectors that together form one EPS12V connector (permanently attached to the power supply).
• Two cables with one six-pin connector for video cards each (one permanently attached to the power supply and one available thru the modular cabling system).
• Two cables with one six/eight pin connector for video cards each (one permanently attached to the power supply and one available thru the modular cabling system).
• One SATA power cable with four SATA power connectors (modular cabling system).
• One SATA power cable with three SATA power connectors (modular cabling system).
• Two peripheral power cables with three standard peripheral connectors and one floppy disk drive power connector each (modular cabling system).

This configuration is good enough for a 750 W product, providing four connectors for video cards, allowing you to connect two video cards that require two power connectors each.

The cables that are permanently attached to the unit are 22” (56 cm) long, while the ones from the modular cabling system are 19 ¾” (50 cm) long up to the first connector and then 5 7/8” (15 cm) between connectors.

All cables use 18 AWG wires, which is the minimum recommended, but the main motherboard cable uses thicker 16 AWG wires for the +3.3 V output, which is great.

Let’s now take an in-depth look inside this power supply.
