Corsair TX Series TX750 750 Watt Power Supply

Corsair has been offering reliable and high performing power supplies for many years and are now one of the most recommended brands around.  Their HX520 and HX620 watt models paved the foundation for their newer series of power supplies.  Today, we are going to take a look at the TX series of power supplies from Corsair. The TX750W is the highest wattage power supply from the TX series, offering up to 750 Watts of power. What makes the TX series unique is a strong single 60A +12v rail, which offers plenty of power. It is also 80Plus certified and SLi-Ready Certified.

Upon opening the box, you will find the manual, screws, higher gauge power cable, some zip ties, and a corsair case badge.

The manual is helpful in describing the installation process and specifications.

The power supply comes with a nice Corsair branded bag over it.

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

The Power Supply:

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

A sticker with the model number is found on either side of the power supply.

Looking at the top of the power supply, there is a Corsair label with their logo on it, the model number and a condensed specification list.  Note that there is a single +12v rail supplying up to 60 Amps, which is great for peripherals requiring more power such as a multi-core CPU's and/or multiple graphics cards.  The 3.3v supplies up to 30 Amps and the +5v supplies up to 28 Amps. The efficiency is 80 percent or greater at 20%, 50% and 100% loads.

There is an large grill on the back which allows the 140 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.  Note the sticker with the model number on it.

This power supply features the following cables:

This power supply is not modular and has a bundle of wires protruding from the unit.  Good thing Corsair includes some zip ties, or else these wires would be quite messy inside a chassis.  The cable length is plentiful even for full sized computer cases, which is good.

-A 24-pin ATX power connector with removable 4 pin for backwards 20-pin compatibility.

-A 4-pin / 8-pin +12v EPS Power Connector.

-4x  6+2-Pin PCI-Express Power Connectors.

-8x Molex Power Connectors

-8x Serial ATA Power Connectors

-2x Floppy Power Connectors

Cooling:

There is a 140mm fan on the bottom of this power supply.  During testing, at idle loads, this fan is somewhat quiet, emitting a faint whooshing sound, which is alright for a 750 Watt power supply, not the quietest 750 watt I have heard.  With loads, the fan didn't seem to speed up much, staying pretty much at the same speed.

Inside the Power Supply:

* Taking this power supply apart will void the warranty.

Inside the power supply, there is a single PCB, barely taking up the available space in the casing.  There are three large sparsely finned black heat sinks to cool down the voltage rectifiers.  The main transformer is on the right, with a CWT model number on it.  The primary capacitor is Panasonic branded, while the secondary capacitors are Nippon Chemicon branded.  Both primary and secondary capacitors are manufactured in Japan, both very high quality. The PSU's board layout is typical of CWT's award winning PSH design.  This power supply is manufactured by Channel Well Technology, which is a fairly new supplier for Corsair.  Their power supplies have previously been manufactured by another company, Seasonic.

The Primary capacitors are Panasonic branded.

The secondary capacitors are Nippon Chemicon branded.

The fan inside is a Yate Loon GP series branded fan, another high quality component in addition to the capacitors. It has the model number D14BH-12 with a maximum draw of .70 AMPs.

Testing:

For this power supply, the test system consists of the following:

-Antec Nine Hundred Case

-Intel Core 2 Quad Q6600 Quad Core Processor @ 3.4 GHz

-ZeroTherm Nirvana 120 Heatsink

-eVGA nForce 680i SLi Motherboard

-2GB (1GB x 2) of Mushkin XP2-8500 DDRII-1066 Memory

-320GB x 4 Western Digital 16MB Cache Hard Drives

-2x nVIDIA GeForce 8800GTS (G92) Video Cards @ 715MHz Core / 1000 MHz Memory

Capacitor Brands:

Excellent, Japanese manufactured capacitors.  High Quality.

Primary: Panasonic/Matsushita

Secondary: Nippon-Chemicon

Voltage Results:

+The results were excellent for this power supply, well within range.  The voltages barely budged when transitioning from an idle state to a load state.  Great!

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 speed did not vary, just making the same whirring and whooshing sound as in idle mode. The fan is a little louder than what I would like to hear in a 750 Watt class power supply at idle loads, but it is still acceptable.

Installation:

+Installation of this power supply went well.  No issues fitting inside the test system's case.  The zip ties helped a lot with keeping everything neat and is thoughtful of Corsair to include.

Conclusion:

This power supply would be ideal for anyone looking to build a quad core system with multiple video cards.  It also is SLi Certified for up to two GeForce 8800 GTX GPU's, but I am sure that it can handle more than that, with its four 8-pin PCI express connectors.  It also has an abundance of power cables, eight molex and eight SATA power connectors. At around $120, this power supply is priced adequately for a high quality 750 Watt PSU.  Overall, this is a great power supply and should be purchased by anyone looking for efficiency, a strong single +12v rail, amazing output performance, and a trusted brand name.

Pros +

-Excellent power output

-Abundance of power connectors

-Five Year Warranty with online tech support.

-Long cables, great for full sized cases

Cons -

-Fan is a little loud

-Cables are not modular, small cases may have trouble dealing with them.

Techaddicts.net would like to give this power supply an 'Highly Recommended' rating.
