Antec TruePower 2.0 TPII-550 (550W)

The TruePower 2.0 looks somewhat unassuming in comparison with the two previous models, especially against the Phantom 500. It seems to be just another gray-colored power supply. Well, its specs don’t promise anything exceptional, either. It is a rather ordinary ATX12V 2.0 model that follows the recent fashion trends and has appropriate certificates, but what model doesn’t have them now?

The actual manufacturer of the power supply is CWT.

You can identify the manufacturer even without looking it up in the UL certificate database, so typical the internal design of this model is. CWT supplies this very model to many trademark holders, so if you put, say, an Antec TruePower and a Foxconn WinFast down next to each other and remove their covers, you will hardly tell what brands they are sold under.

The PSU has a standard internal design except for independent voltage regulation which is represented by the three large toroidal-core chokes of magnetic amplifiers located near the output circuitry. The PSU has neither active nor passive PFC. It is an American model because European PSUs must have some kind of PFC.

The PSU has a high load capacity of the +12V rail (a maximum current up to 36A with a division into two “virtual” output lines with a maximum of 19A on each) as well as of the +5V rail (as much as 40A, which is almost two times the load capacity of this rail in a majority of today’s ATX12V 2.0 PSUs). The latter can only be of use to owners of old top-end systems in which the old power supply has failed. There were once even dual-processor mainboards that powered the CPUs from the +5V, but the manufacturers soon realized the lack of prospects of that solution.

The PSU is equipped with the following cables and connectors:

  • Mainboard cable with a 20+4 connector (54cm long)
  • CPU cable with a 4-pin connector (51cm)
  • Two graphics card cables with 5-pin connectors (53cm)
  • One cable with two Molex connectors and one floppy mini-plug (53cm to the first connector and 15cm more to each next connector)
  • One cable with three Molex connectors and one floppy mini-plug (53 to the first connector and 15cm more to each next connector)
  • Two cables with two SATA power connectors on each (53cm+15cm)
  • One cable with two 4-pin Molex connectors for system fans (27cm+10cm)
  • A cable to control the speed of the PSU fan (45cm)

The mainboard cable is sleeved. The other cables are just tied up with nylon braces. As the result, wires from different cables may get entangled. Moreover, the different wires in the same cable vary slightly in length.
