Corsair TX750W Reviewccokeman - June 2, 2008

The TX750W is a non modular power supply. As such, all of the connections are hardwired back to the power supply with no breaks in the connection. Some people prefer this method over the modular design because any break in the circuit can potentially lead to a voltage drop or create increased resistance and heat generation at the modular connection point. The merits of a modular power supply are well known, so no further discussion is needed. Instead of a flashy exterior, the TX750W has a rough matte black finish. This finish just says, "I am all business. No need for flash." Kind of like that old Dodge you see prowling the streets late at night. Spray can primer black coloring and a set of understated big and littles, the thing that stands out is the exhaust note, rough and ready for action. Kind of like this power supply.
The top features the specifications of the TX750W listed in the typical format. The bottom of the unit houses the 140mm, yes I said 140mm, cooling fan. Plenty enough to keep the internals cool. The rear face is almost entirely mesh to keep the air moving. The power switch is located here, as well as the universal input for the power supply cord. The sides are labeled with the model number and the Corsair logo, so when you have that side window showing off your wire management skills, the power you are packing shows.
The number of connections available on the TX750W are pretty standard; ATX 24-pin, ATX 8-pin auxillary 12v, four 8-pin PCIe, eight SATA, eight 4-pin Molex and two floppy connections. The cables are all sleeved back just before they enter the power supply housing. This power supply is SLI ready.
One thing you do not want to do is open your power supply. For one thing, if warranty is a concern, opening the unit will effectively void the warranty. The other reason is a little closer to the heart, and that is safety. The capacitors can keep a charge long after you power down the unit, making for a hair raising experience if you touch one that has not been discharged. For those reasons, I suggest again that you leave this to people that have experience in such things.
Carefully opening the power supply and lifting the top reveals the 140mm Yate Loon fan. This fan is rated at 2800 RPM, 140 CFM and 48.5dBA at 12 volts. An awful lot of airflow and high noise penalty as well. The upside to this fan is that it is temperature controlled and should be quite silent when not spooled up. Included on this fan is a clear plastic deflector toward the rear of the case. This presumably is to force more air through the power supply to provide adequate cooling rather than allow the rear airflow to just blow out the back of the power supply with no cooling benefit.
Inside the power supply you can see the primary capacitor and PFC coil just to the left of the capacitor. The primary cap is made by Matshushita while the secondary caps are manufactured by Nippon Chemi-con. The secondary side has all of the wiring streaming into the housing and soldered onto the main PCB.
Let's see how the TX750W performs.
