Testing:
The quality of the power being supplied to the components in your system is more important than most users realize. A poor quality power supply can cause many problems and in some cases can even destroy system hardware. An under powering PSU may cause corruption of data, system lockups, and program crashes. In more severe cases an over volt can fry components. The TW750W PSU is designed for the enthusiasts sporting a single +12v rail to provide support for today’s high-end systems.
TWL hooked up the TX750W to our test system shown above and we polled each rail to see where if any there was a loss or notably less power on any of the rails. The TX75W comes with a mass amount of cables designed for the high end system with all the internal peripherals plugged in.
The results after polling each rail were surprisingly close on wattage under load, resulting in plenty of room for more! Powering on the system and holding a volt meter to each rail to watch the needle bounce if at all was another interesting mark where once the PSU was turn on, the meters’ needle instantly jumped to the rails set voltage and it did not move even when the SATA drives did their spin up. It was very impressive for the power supply to adjust to the demand of the peripherals within a fraction of a second to the point the PSU didn't over power or under power at all during the boot up process and under load. Also while testing, we kept a thermometer on the exhaust of the PSU and remarkable so, the temperature of the air coming out PSU was noticeably just a few degrees warming than room temperature. Meaning that even under heavy loads the PSU did not turn into a small blast furnace to keep up with demand. Those of you who have your rig in a small room with the TX750W PSU won’t get too hot due to PSU exhausting heat similar to a small space heater one would use in the winter time.
