Corsair TX750W Power Supply Review

A Look Inside The TX750W

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.On this page we will have an overall look, while in the next page we will discuss in details the quality and rating of the components used.

We can point out several differences between this power supply and a low-end (a.k.a. “generic”) one: the construction quality of the printed circuit board (PCB); the use of more components on the transient filtering stage; the active PFC circuitry; the power rating of all components; the design; etcetera.

Figure 7: Overall look.

As soon as we opened the power supply we had a déjà vu feeling. The layout was very similar to the one used by Thermaltake Toughpower 750 W, which is also manufactured by CWT. However, after a closer inspection on the printed circuit board we could find enough differences to say for sure that even though they have the same labeled power and are manufactured by the same company, they are definitely different products (also Thermaltake’s product has three 18 A +12 V rails while Corsair’s has a single 60 A rail).
