hola gente esta vez traigo un review, que hago copy paste de hardwaresecrets una página prestigiosa en el ámbito de los bench, review, etc...
Este post lo hago para todos aquellos que quieren comprarse una buena fuente y creen que thermaltake es buena, no se fien, es mucha publicidad lo que tienen encima, después terminas jodiendo todo el equipo.
si no quieren leer todo busquen las partes rojas subrayadas que son las que contienen información negativa sobre esta placa. y en verde lo bueno
en este caso vamos a mirar adentro del modelo Thermaltake TR2 RX 750w TRX-750M Modular la que te venden como la gran cosa, capas de hacer arrancar tu auto mientras alimenta a tu lavarropa......y encima con el precio que piden: $ 800 pesos!!!!
Introduction
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” (160 mm) 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 through 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 through 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.
Now let’s take an in-depth look inside this power supply.
A Look Inside The Thermaltake TR2 RX 750 W
We decided to disassemble this power supply to see what it looks like inside, how it is designed, and what components are used. Please read our Anatomy of Switching Power Supplies tutorial to understand how a power supply works and to compare this power supply to others.
This page will be an overview, while in the following pages we will discuss in detail the quality and ratings of the components used.
Transient Filtering Stage
As we have mentioned in other articles and reviews, the first place we look when opening a power supply for a hint about its quality is its filtering stage. The recommended components for this stage are two ferrite coils, two ceramic capacitors (Y capacitors, usually blue), one metalized polyester capacitor (X capacitor), and one MOV (Metal-Oxide Varistor). Very low-end power supplies use fewer components, usually removing the MOV and the first coil.
This power supply is flawless on this stage, with two Y capacitors, two X capacitors and one ferrite coil more than the minimum required.
Power Distribution
As you can see, according to the label this unit has a single +12 V rail, so there is not much to talk about here.
Now let’s see if this power supply can really deliver 750 W.
Load Tests
We made several tests with this power supply, as described in the article Hardware Secrets Power Supply Test Methodology.
First we tested this power supply with five different load patterns, trying to pull around 20%, 40%, 60%, 80% and 100% of its labeled maximum capacity (actual percentage used listed under “% Max Load”), watching how the reviewed unit behaved under each load. In the table below we list the load patterns we used and the results for each load.
If you add all the power listed for each test, you may find a different value than what is posted under “Total” below. Since each output can vary slightly (e.g., the +5 V output working at 5.10 V), the actual total amount of power being delivered is slightly different than the calculated value. On the “Total” row we are using the real amount of power being delivered, as measured by our load tester.
The +12VA and +12VB inputs listed below are the two +12 V independent inputs from our load tester. During this test both inputs were connected to the power supply single rail (+12VB input was connected to the power supply EPS12V connector and all other cables were connected to the load tester +12VA input).
Note: We are now using the names +12VA and +12VB for the two inputs from our load tester because some people were thinking that the “+12V1” and “+12V2” names present on our table referred to the power supply rails, which is not the case.
According to our methodology, Thermaltake TR2 RX 750 W cannot deliver its labeled wattage. It burned after one minute delivering 750 W at a room temperature a little bit above 45º C. Thinking that we may have got a defective unit, we asked Thermaltake another sample, which burned exactly the same way. In both units the component that burned was one of the +12 V rectifiers.
De acuerdo a nuestra metodología Therm...TR2 RX 750W puede entregar la potencia etiquetada. Se quemó luego de 1 minuto entregando 750W a una temperatura ambiente apenas superior a los 45ºC. Pensando que podría tratarse de una unidad defectuosa, pedimos otra la cual se quemó igual que la anterior. In ambas unidades el componente quemado fue uno de los rectivicadores de +12V
Efficiency was always high when we pulled up to 60% of the power supply maximum load (i.e., up to 450 W), between 84.5% and 86.4%. But at 80% load (600 W) efficiency dropped to 81.9%, still above the 80% mark. At full load we couldn’t measure efficiency, because the unit burned before we could read all numbers.
Not being able to deliver its labeled wattage is not the worst about this power supply.
Noise and ripple levels were way above the maximum allowed during tests four and five. With the first sample, noise levels during test four was 130.2 mV at +12VA and 127.6 mV at +12VB, jumping to 183.8 mV and 166.8 mV during test five, respectively. We got even worse results with the second sample, as it also failed on +5 V and +3.3 V, as we summarize in the table below. The maximum allowed is 120 mV on +12 V and 50 mV on +5 V and +3.3 V. All these numbers are peak-to-peak figures. Below we show the scope waveforms for you to see the problem.
No entregar la potencia etiquetada no fue lo peor de esta fuente. Los niveles de ruido y ripple estuvieron por encima del máximo permitido durante las pruebas 4 y 5.
+12VA input from load tester during test five with the first sample (154.4 mV).
+12VB input from load tester during test five with the first sample (155.2 mV).
+5V rail during test five with the first sample (45.6 mV).

Conclusions
Thermaltake TR2 RX 750 W is, according to our methodology, a flawed product that must be avoided at all costs. It can’t deliver its labeled wattage at high temperatures, but this is not the worst of it: ripple and noise level are way above the maximum allowed when you pull 80% or more from the unit’s labeled capacity (i.e., 600 W and above), overloading your components (especially electrolytic capacitors from the motherboard and video cards), which can cause your PC to present an erratic behavior (crashes and random resets) and, under extreme conditions, damage components.
La Therm...TR2... es, de acuerdo a muestros métodos, un producto defectuoso que debe ecitarse a toda costa. No puede entrega la potencia etiquetada en alta temperaturas pero sin ser esto lo peor. El ruido y el rizado estuvieron por encima de lo permitido cuando se ponía la fuente encima del 80% de cu capacidad nominal. (p.e. 600W y más), sobrecargando los componentes (especialmente los capacitores electrolíticos de la mother y la tarjeta de video), lo que podría causar un comportamiento errático de la PC (cuelgues y reseteos aleatorios) y bajo condiciones extremas : DAÑO A LOS COMPONENTES.
