Thermaltake TR2 RXThermaltake being one of the leaders in power supply production has once again sent us one of their prized power units. The TR2 RX is aimed at the mainstream segment, for people that are looking for efficiency, decent amount of power and reliability. The TR2 has all that. It is rated 86%, anywhere from 600 to 750 watts and has a great warranty which last five years from date of purchase. We will be taking a look at the 750 watt which has support for dual GPU no matter the card has two 6-pin or 8-pin connectors. We have it here.

 

Introduction to the Thermaltake TR2 RX

Think about all the components that are packed into a computer tower these days. There is multiple graphics in some cases, at least a multi-core processor at least four cores and until the price of solid state drives get affordable multiple hard drives are also present. When you give it a few minutes of thought you will realize that you can quickly grow your old power supply. Getting a new power supply something that many people hate to spend their hard earned money on. But if you think about it its easy one of the most important pieces in your rig. So, an upgrade just may fit the build.

Closer look

A few weeks ago we took a look at the Thermaltake EVO line of power supplies that displayed a lot of bling while providing some very decent rails. Today, we will taking a look at another Thermaltake power supply which is the entry level unit entitled the TR2 RX. The TR2 RX comes in two series which are TR2 Standard which is a non-modular model and the RX which is modular. And each consist of models ranging between 430 and 1200 watts. We will be taking a look at the 750 RX2 model.

The TR2 uses a huge 140mm cooling fan to exhaust air from the inside of the PSU. We found that the fan is the TR2 was just as quiet as the one used in the Zalman ZM600 we reviewed last week. According to Thermaltake the fan is rated at 2200 RPM. No other information is given.

The RX2 is covered in a attractive gunmetal coating which is a nice change from the typical black PSU. Physically there is too much to the unit. The side of the unit where the power switch is consist of the typical ventrilation opening but instead of the typical level switch Thermaltake used a round button, which is a change from the norm.

Many of you will be happy to know that the RX2 is a modular. Permanantly attached are the main ATX, aux 4/4 and one PCIe power connectors. When a company 'must' make some cables permenant it would like to see them make one extension a couple of SATA power connectors. In the case of the TR2 I would have had all the plugs I needed to complete a build. And if you think about it thats all the conenctions you really need today.

Testing
We know that testing a power supply on a loaded system is not the very best way to do so, but you can not overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. But we do have a trusty digital multimeter. These sites and the method they use should be the true means of determining how good a power supply really is. We feel that showing you how it performs under real world conditions is also a valid measure of its performance.

Testing Hardware:

Motherboard: Gigabyte GA-EP55A-UD6
Processor: Intel Core i7 860 @ 3.8 @ 1.4v
Ram: G-Skill ECO PC12800 4GB Dual-Channel
Video Card: XFX HD 4770
HDD: Seagate 7200.11
Power:Thermaltake TR2 RX 750
Case: Sunbeamtech Open-Air Bench
Cooling: Coolermaster 212 Plus
OS: Windows 7 RC
Thermal compound: Arctic Silver 5

Results

If you want a decent power supply that is capable of supplying enough power to feed a couple of starving video cards like Radeon HD 5770 or Nvidia 250 then the TR2 RX 750 is your unit. In the testing we saw that it was very stable and well in specs. We saw the 12v rail drop a little more than some of the other units we tested but nothing serious at all.


 

Conclusion

The TR2 RX 750 has three thing going for it: ample power, modular and made by a well respected company. Each of which is just what a protential buyer would look for in a power supply. In the test the power was more than stable and also the price is right. At the $100 price point you really can't go wrong. What I really liked about the unit is that it was clean. This is the total opposite of the Thermaltake EVO we reviewed some time back.

The only negaive that I could see with this unit is that the cable maybe a little short in some mid-size towers or taller. In towers like the smaller Element series no problem. But cases like the new Element V which are several inches taller you may see this problem. Other than that no problem.
