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.

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.

| 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. |
