Installation

I installed this unit in an existing system, as opposed to an empty case. Installation of the TX750 wasn't particularly unusual. Despite the unit's extra bit of length beyond standard size, this didn't make it any more difficult to install. The bulk of cables was perhaps more of a nuisance. I solved this problem by shoving them through the front 5 1/4" bay area of the case as I slid the power supply into the chassis.

Noting the TX750's four PCIe cables, four SATA and the like, I found myself with a few unneeded wires that I kept in the 5 1/4" bay area, to avoid congestion near the heat-generating motherboard and hard drives.

Performance

To put the TX750's stability to the test, I chose OCCT for monitoring voltages over a period of time while under load. I allowed OCCT to run a 2-hour taxing memory and CPU sequence and was shown graphs of the results upon completion.

All of the lines operate at a slightly higher voltage than suggested by Corsair. The 3.3V line, powering most particularly the CPU, operated between 3.34V and 3.36V. This was a maximum difference of 1.8% from the declared 3.3V value of the line. Corsair provided a regulation of 5% for this line, which the line obeys very well. The ripple was a tame one, of about 30 millivolts, which is also well within the 50 millivolt range as provided by Corsair.

Next, the 5V line, which was rock-hard stable. I was given a very nearly immutable 5.11 volt reading, or 2.2% from 5 volts. This was well allowed in Corsair's 5% regulation. The ripple, nearly nonexistent, was 20 millivolts when it occurred, well within the 50 suggested.

Finally, the 12V line was specified to have a maximum 3% regulation and 120 millivolt maximum ripple by Corsair. I observed a maximum of 12.2 volts from this line, which a 1.6% difference. The ripple was 50 millivolts, less than half of the maximum allowed.

Overall, I saw very commendable performance and stability across all lines from the TX750. Heavy load did not falter its ability to provide sufficient and static voltage to powered components.

I also should point out that this is a very quiet component. During normal use I saw little more than light activity from the TX750's 140mm fan, and heard even less. At no time could I hear the TX750's fan overpowering the sound of the CPU or chassis fans.
