Closer Look: Antec TP-650


Packaging may very well influence a purchase, or possibly even draw your eye to the product initially. Of course, a special value should be placed on protective packaging beyond the average, and the TP3-650 is no exception. The cardboard package which Antec uses is ideal for retail shelves and warehouses, but it is not suitable for standalone shipping and should be packaged with protective surroundings for shipping. However, if you are like most people including myself, the packaging is quickly discarded once you have the unit installed and it has survived initial break-in and testing. I will not include package views from every angle, as I feel it unnecessary and that most of you would skip past them anyway.

Antec TP3-650 TruePower Trio 650W PSU

Included Components

  • (1) TP3-650 Power supply with 24-pin main connector with detachable 4-pin section, a 12V 4-pin connector for single CPU systems, and a 12V 8-pin connector for multi-CPU systems
  • (1) User Manual in seven languages
  • (1) AC power cord
  • (4) Mounting screws
  • (2) Cable bands

The native cable group includes:

  • (6) 4-Pin Molex peripheral connectors
  • (4) 15-Pin SATA connectors
  • (2) 6-Pin PCI Express connectors
  • (1) Floppy connector

As evidenced in the contents for the TruePower Trio, the floppy connector is a soon to be extinct feature in the power supply industry. There has been a slow trend to remove this connector completely, but I suspect it will be at least another year before we have seen the last of it.

In addition to the standard set of connectors, Antec includes two other specialized connectors:

  • (2) 4-Pin Molex “Fan Only” connectors (for up to two fans supported)
  • (1) 3-Pin fan speed sensor connector

The “Fan Only” power connectors allow the Antec TruePower Trio to control case fan speeds for up to two fans, thereby reducing total system noise as temperature is monitored.

Internal Components

The internal view of the Antec TruePower Trio looks exactly like most other power supply units you might be used to seeing. The voltage regulator heatsinks are standard design sheared large-gauge aluminum. Despite the lack of more effective heatsinks, the internal temperatures for the TP3-650 remained very low thanks to the efficient design. Rather then use two separate 200V main power capacitors, Antec elected to use one 400V capacitor rated at 470uf. Overall, I did notice that Antec used fewer components in the design of this TruePower Trio 650W power supply unit then what is commonly used in other comparable power supplies. This simplified design will most likely yield fewer failures, however once you open the case to the Antec power supply your warranty becomes void.

Cooling Fan

The Antec TruePower Trio series of power supply units are so efficient that Antec has designed the cooling fan to concentrate its draft onto the most critical components. In the TP3-650, a single ADDA brushless 120mm fan is used. This fan is very popular for use in power supply units, and with a 0.37A rating, it could move high volumes of air; but the Antec temperature monitoring components will likely never push it that far. In all of my tests, this unit never make more then a slightly audible sound.

Also pictured is he 120mm fan with the shroud removed, for reference purposes. Antec did not utilize any rubber grommets at the mounting locations, which appears to becoming an emerging standard for high-end fans. The fan is not equipped with standard power connectors, but rather a proprietary connector which houses the two power wires, while the thermal sensor wire is fused directly to the power supply unit.
