Antec has developed a strong following at Silent PC Review, and rightfully so. They've offered many successful cases, including the P180 and the NSK2400 / Fusion which our own editor Mike Chin helped to create. Antec also has a strong showing with power supplies as well with three PSU's on SPCR's recommended quiet PSU list. Hopefully Antec will keep the ball rolling with the Antec TruePower Trio, the latest PSU models we have received from them.

The TruePower Trio comes in 430W, 550W and 650W power ratings. This article will focus on the 550W model. We received a sample of the 650W version as well, but it is here for reference only. The quality of these models should be very similar.

The TruePower Trio's are the next generation up from the Antec TruePower 2.0 (reviewed) and given that there are three models, the name seems fitting, although we're not sure that's what the name refers to. Perhaps it comes from Antec's claim that there are three +12V power supply rails. While the TruePower 2.0 was an adequate power supply, it did have some noise issues that were undesirable. Hopefully Antec got it right and the third time really is the charm.


The TruePower Trio models come in nice retail boxes.

Somewhat ecologically friendly packaging

FEATURE HIGHLIGHTS AND SPECIFICATIONS

With the power ratings, styling and features of the TruePower Trio, Antec appears to be trying to extend its reach into the gaming market.

Ante TruePower Trio 550W / 650W Feature Highlights (from Antec's web site)
FEATURE & BRIEF OUR COMMENT
Nvidia SLI certified
To be expected with these output ratings.
Universal Input, automatically adjusts for 100V to 240V power grids Fairly standard 100V to 240V input range.
Active Power Factor Correction (PFC) for environmentally friendlier power PFC reduces the apparent power drawn from the wall.
Three 12V output circuits provide added system stability This is beneficial given the high demand for 12V current in modern computer systems.
Accurate power rating allows TruePower Trio to deliver its full rated power, 24 hours a day rated at 50ºC This is good, but honestly, it should be expected.
Up to 85% efficiency Higher efficiency means less power wasted in the form of heat, but this doesn't specify what range of outputs will result in the stated value.
120mm low noise cooling fan Standard.
Fan Only power connectors allow TruePower Trio to control case fan speeds, reducing total system noise
This is a nice feature that can save some money on fan controllers.
Dedicated outputs for stable output and less ripple noise
Dedicated outputs are preferred. A PSU with non-dedicated outputs will have only the highest output rail regulated and the lower output rails tied to it.
Feedback loop circuits for tighter load regulation (±3%) to maintain accurate voltage to all components
Good.
Heavy duty protection circuitry prevents damage resulting from short circuits (SCP), power overloads (OPP), over voltages (OVP), and under voltages (UVP)
About par for the high end.
4 SATA connectors for Serial ATA drives
Standard.
Two PCI-E connectors for PCI-Express video cards on 550W and 650W models, one connector on 430W model
Related to the SLI statement made above. Mostly irelevant when considering a silent PC since it will be hard to silence a dual video card system.
MTBF: 80,000 hours at 25°C
80,000 hours is over nine years; a very long time in the life of a computer.
Safety approvals: UL, CUL, FCC, TÜV, CE, C-tick, CCC, CB The more the merrier.
Power Factor value up to 99%
Related to the power factor statement made above. 99% is well above the Intel specifications.
Gold plated connectors for superior conductivity An esoteric feature of questionable merit.
AQ5 - 5 year warranty A five year warranty is very good.
