Corsair TX750 750W Power Supply Review

Output Characteristics


For this power supply, Corsair has gone with a single massive 60A +12V rail which can output 720W of power. I have said it once and I will say it again: having a large +12V rail is a must in this day and age. Nearly all of the most power hungry components draw power from the +12V rail(s) and having 96% of the total power available on the +12V rail like the TX750 does ensures sufficient power delivery. To tell you the truth, this 60A of available power on the +12V rail is extremely high for a 750W power supply.


Interior Impressions


The interior of the TX750 is quite typical for a CWT-built power supply with its solid ribbed heatsinks and wrapped chokes. It seems like all of the components were shoe-horned onto the single PCB so they could fit into a power supply with a 120mm intake fan. You can see evidence of this with the inch of space between the main PCB and the right-hand edge of the power supply casing.


There is a small secondary PCB located on one side of the TX750 which holds the primary fan connector but it also holds two other connectors. Unfortunately, I couldn’t trace where the wires coming out of these two connectors went but it looks like one of them runs back onto the primary PCB’s +5V solder points.


The primary capacitor is a 105*C Matsushita unit while those on the secondary are exclusively Nippon Chemi-Con caps. Both of these choices are top-notch and run will with the high-output design of this Corsair power supply.
