Antec Truepower New 750 Watt Modular Power Supply

Antec has been offering power supplies that offer performance and reliability at a reasonable price for a while now. Today, we are going to take a look at Antec's Truepower New series.  The Truepower New series are now built on a new Seasonic designed platform.  We will be reviewing the 750 Watt model, which is currently the highest wattage offered in this series.  There is also a Blue LED lit version of the 750 watt model. This power supply is SLi Ready (up to two GeForce GTX 260's in SLi) and 80Plus Bronze certified.

Upon opening the box, you will find the users manual, a power cable, and screws

Here are some of the main features and specifications from Antec's Website:

The Power Supply:

The power supply features a matte graphite black housing and fan grill, which looks great.

Looking at the side of the power supply, there is a label with Antec's logo on it, the model number and a condensed specification list.  Note that there are four +12v rails, each supplying up to 25 Amps for a total of 100 Amps, which is great. The 3.3v supplies up to 25 Amps and the +5v supplies up to 25 Amps. The efficiency is 80 percent or greater at 20%, 50% and 100% loads.  According to the 80Plus website, this power supply has an average efficiency of 86.31% at typical loads (50% load) and an overall average efficiency of almost 85%.  This is a new feat for the TruePower series of power supplies!

There is a large square grid style grill on the back which allows the 120 mm fan to exhaust hot air, an on/off switch and AC Power Input.  This power supply does feature Active PFC, so there is no need for a  switch to select the input voltage.

This power supply features the following cables:

This power supply features a mix of hardwired and modular connections, which Antec labels as "Advanced Hybrid Cable Management".  I found that most of the connectors I needed were already hardwired, so that is great.  All of the connectors are clearly labeled.  The PCI-e cables utilize the two red eight pin sockets, while the peripherals utilize the two black six pin sockets.

-A 24-pin ATX power connector

-A 4-pin +12v CPU Power Connector

-An 8-pin +12v CPU/EPS Power Connector

-2x  6+2-Pin PCI-Express Power Connectors and 2x 6 Pin PCI-Express Power Connectors

-6x Molex Power Connectors

-6x Serial ATA Power Connectors

-1x Floppy Power Connector

Cooling:

There is a 120mm fan on the bottom of this power supply.  During testing, at idle loads, this fan is  super quiet, making very little to no noise.  This is really impressive. I'm glad that Antec incorporated the PWM fan speed control technology. With loads, the fan sped up a bit, making a light whirring sound, but the noise was still very acceptable.  Great job with the fan, Antec!

Inside the Power Supply:

* Taking this power supply apart will void the warranty. 

Inside the power supply,  there are three large black colored heat sinks, used to cool down the voltage rectifiers.  The main transformer is in the middle of the image, while the smaller transformer is below it.  The primary capacitor is Nippon Chemicon branded and rated at 85c, while the secondary capacitors are also Nippon Chemicon branded. The PCB layout and board quality is pretty good.  If you look closely at the heatsinks ,you can see the holes used to mount the blue LED's in the Antec Truepower New 750 Blue.  They are built on the same platform otherwise.

The Nippon Chemicon branded primary capacitor.

The secondary capacitors are also Nippon Chemicon branded.

The fan inside is an ADDA branded fan, which is very common in Antec and Seasonic built power supplies.  This is a high quality fan, featuring a PWM power connector.   It has the model number AD1212HB-A7BGL with a maximum draw of 0.37 Amps.

Capacitor Brands (subjective rating):

Primary: Excellent

Secondary: Excellent

Primary: Nippon-Chemicon

Secondary: Nippon-Chemicon

Voltage Results:

+The results were excellent for this power supply, the results being well within range.  All rails remained quite strong.  There was some slight fluctuation in the voltages, but nothing serious or out of the test range. 

Stability Results:

+Everything ran fine during testing, the system was stable and performed the tests as expected. 

Fan Speed Impressions:

+During the tests, the fan was extremely quiet with idle loads and only produced a slight whirr with loads.  I am very happy with how the fan performed.

Installation:

+Installation of this power supply went well.  There were no issues fitting it inside the test system's case.  Since this power supply is modular, the interior of the case was much neater because unneeded cabling can be put away. The amount of hard wired 'hybrid' cabling is perfect for the average system and does not add extra clutter.

Conclusion:

This power supply would be ideal for anyone looking to build multi CPU core gaming / workstation system with two or more moderately powered video cards.  This power supply is nVIDIA SLi Ready and is certified to be able to run up to two GeForce GTX 260's in SLi.  I'm sure it can handle most of nVIDIA's other GPU's in SLi as well. I was really impressed with how quiet the fan was upon starting up my system.  It is nearly inaudible, which is great for users who want to build quiet computing systems.  It is also 80Plus Bronze certified.  At around $100, this power supply is priced perfectly for its wattage rating.  Overall, this is an excellent 750 watt class power supply.  The Antec Truepower New 750 Watt should be purchased by anyone looking for high efficiency, low noise, great output performance, and great build quality in a power supply.
