Corsair TX750W 750watt Power Supply

In The Box




Once we get into the dark box with the orange lettering, we see that we have everything we need to get down to business. There is even a cloth bag to make certain everything stays nice and neat. While not a modular design, all cabling harnesses are wrapped in a plastic mesh material so cable management should not be too difficult. The cabling coming from the housing is also protected by a plastic grommet to ensure a safe exit with no chance for the metal grinding away at the plastic coating of the wires and causing a short.


This power supply is rated at 750 watts of continuous power draw, so should be more than enough to handle anything you want to throw at it. The 3.3v rail is rated at 24A and the 5v rail is rated at 28A. Many current power supplies are moving to a multiple 12v rail setup, but the TX series from Corsair gets back to basics and has a single 12v rail that is rated at an impressive 60A. This is ideal for those pushing hardcore cooling (peltier) solutions, have a bunch of powerful fans and a more than normal amount of peripherals installed. You will not have to worry about a rail not being able to handle the draw since there is only one rail to concern yourself with. And folks, if you can pull more than 60 amps of juice, you are probably the type who has a backup generator sitting outside your window to handle the power requirements.


The features included on this TX series model include many that are finally becoming common. These include support for ATX12V v2.2, 80%+ power efficiency ratings, Active PFC and all Japanese made capacitors for reliability and longer life. Add to this an above average 5-year warranty and we have the makings of a very nice product here.



The exterior surface area is pretty barren, but this is becoming a standard practice anymore since it enhances the amount of exhaust to allow for better airflow. On this panel you will see a port for the power cable and a toggle switch that allows you to turn off the power supply. Everything else is internal, including the switch that sets the voltage from 120v to 240v.



With all that real estate on the exterior panel for exhaust, it stands to reason that Corsair would maximize that and use a large fan. The 140mm unit installed on the bottom of this PSU has the ability to push a lot of air at need. During our testing, the noise level of this fan was always lower than other system fans being used. At idle it is silent, while at higher speeds it makes little noise. The fan is controlled internally by a thermal probe, so it only speeds up when the temperatures inside the housing climb to higher levels.



As noted earlier, this model does not feature a modular cable design. While this is a nice thing, it isn't a necessity. You are also assured of having a lot of flexibility with this product since it has plenty of connections for pretty much anything you need.


The primary power coupler is a 20+4 pin design so you can use this PSU with older motherboards or modern ones. Auxiliary power is provided with a 4+4 pin coupler to handle either the 4-pin or 8-pin motherboards. As far as connectors for peripherals you get eight Molex, eight SATA, four PCI-E and two FDD connectors. Also of note is that all four of the PCI-E connectors can be utilized as either 6-pin or 8-pin couplers so you will be set regardless of the video card you happen to be using. It is also nice knowing that you are going to be future proof when it comes time for your next graphics upgrade.
