Lets take a closer look at the power distribution on our 850 Watt
Quattro. Antec named the Quattro line after the four available +12
volt rails and the TruePower designation indicates the power supply
should be capable of delivering the full 850 Watts continuously 24 hours
a day. Most power supplies give their rated wattage off of their
peak power or under some unrealistic lab condition, but with the
Truepower Quattro you know you are getting every but of that juice right
when you need it. The Quattro is also 80PLUS certified which means
it is extra energy efficient using up to 33% less power than similar
the Antec TruePower Quattro 850 Watt power supply into my Intel gaming build. The build includes an
Pentium Core Duo 2 6800 cooled by a passive
AeroCool GT-1000, a Connect3D X1900 XT video card and a 2 x 1 GB kit
OCZ Titanium Series DDR2-6400 mounted on an ASUS P5W DH Deluxe.
Storage was provided by 2 x WD 74 GB Raptors in a RAID0, a
Seagate 750 GB storage drive and a
Plextor PX-755SA 16x DVD burner all mounted into the
AeroCool AE plus.

Here you can see the Quattro installed as the
foundation for my Intel build. Notice the extra length on the
power runs for those long case installations or to hide those pesky
cables for your latest windowed build.
And here you can see the completed build. As the AE Plus
isn't a windowed case, I went with some basic cable management.
Airflow is critical when attempting a passively cooled CPU.
And a second look at the 850 Watt TruePower Quattro.
Without the usual 120mm plus fan on the power supply I ended up
installing a Antec Tri-Cool fan in the default exhaust location.
Things ran nicely but I feel better knowing its there.
test the Quattro 850 I ran
the system overnight idle before capturing these numbers using the ASUS
AI Probe II. With a power supply designed to handle two of the
current power hungry top video cards, the Quattro easily handles my test
build at an idle.
Next I put each build
under load by running
Passmark's BurnIn Test and
Futuremark's 3DMark06 simultaneously or about 15 minutes in two back
to back sessions.
Here you can see the numbers captured under load. The Quattro 850 has no problem with the
system under load. Our numbers only change slightly from the idle
readings and remain rock solid. The single 80 mm fan spins up to
an audible level but exhaust temperatures never reached over 87 degrees.
Not to bad!
To further test the
stability I loaded up
Sandra Version XIIa (Final 12.30). Sandra is an industry leader in performance
tuning and benchmarking offering one of the more reliable environmental
monitors on the market. As you can see form the graph above, the
stability of each rail is confirmed by Sandra.
The stability of the
rail voltage remains consistent while idle in the BIOS. To test the
stability I also used my trusty Cen-Tech multi-tester to monitor the +12
V rails. killing around 4 hours with Civilization IV and Shadowrun
provided no noticeable variations. I was unable to find a
description of the rails on the Antec site. with no way of knowing if the rails are independent I tried daisy
chaining everything possible onto a single +12 V rail. With this
build the 850 doesn't even seem to notice the change.
TruePower 850 Watt Quattro modular power supply is one of the most
stable power supplies I have ever tested. Turing all phases of
testing I was never able to get a single rail to show a measurable
ripple. I am confident even a much more power hungry build would
be handled with ease. If you think your build might out power the
850 Watt rating, there is always the 1000 Watt version waiting in the
The Yellow striping may be the deal
breaker for some of you but I think it really makes the Quattro stand
out from the crowd of generic looking power supplies on the market.
The mix of fixed cables and modular runs gives you
the versatility to use only the cables you need and makes the
installation a breeze compared to a fixed unit.
Possibly the most important thing to
mention in closing is the $249 MSRP on this power supply. A quick
search on Froogle shows this unit can be found under $170. That's
an absolute steal on a power supply with a true Power rating at 850
Watts. And did we mention the 3 year warranty as well? Don't
skimp on the foundation, give your performance PC the power supply it
deserves; a Antec Truepower Quattro.
