Introduction:

Thermaltake Technology Co. Ltd., founded in 1999, manufactured the world's first turbine cooler for the Intel Pentium and AMD Athlon series processors in 2000. The Golden Orb was followed by the all copper Volcano 7 cooler in 2001 the same year Thermaltake became Intel's premier cooler solution provider in Asia Pacific. The company has moved on since then and now includes enclosures, power supplies, coolers for most applications, HDD enclosures, DC cooling fans and gaming accessories in its product line.

Following on from the recently tested Thermaltake Toughpower Grand 1200W power supply OCC will be putting the Toughpower 1350W power supply through its paces this time around. The Toughpower series of power supplies offer +87% efficiency, a modular cable system, Nvidia SLI and AMD/ATI Crossfire certification along with power protection and performance that today's cutting-edge PC components require. Let's have a look at the power supply and see how well it performs.

Closer Look:

The Thermaltake Toughpower 1350W is packaged in a rather large box with a faded photograph of fan grill and modular cable connector panel on its lid along with some of the main features with model and wattage in black on a silver background. Five year warranty, Tt Eco-Friendly, 80 Plus Silver, SLI/Crossfire and AMD Game logos complete the picture. The bottom face of the box carries the technical specification and features which includes the types and quantities of connectors, a specification table, efficiency/load graph and technology features which include the use of 105°C Japanese sourced capacitors and the DC to DC convertors to improve efficiency. The side panels show the Thermaltake trade mark and both end panels give a list of the important features in twelve different languages.

 

 

 

 

 

 

 

 

 

 

 

 

Lift the lid and the user manual sits on top of the white foam enclosed power supply with the captive cables and modular cable bag tucked neatly down the side. The Thermaltake Toughpower 1350W power supply is enclosed in a black felt drawstring bag and comes with a good set of accessories that includes Velcro ties, case badge, mounting screws and power cord.

 

 

 

The Thermaltake Toughpower 1350W power supply is very well packaged and comes with a good set of accessories. All's well here so let's have a closer look at the power supply.

Closer Look:

The finish on the Thermaltake Toughpower 1350W power supply is a slightly textured matt black paint that tends to resist finger prints and offers a certain level of scratch resistance.

 

 

 

 

 

 

 

 

 

 

 

 

 

A hexagonal holed exhaust grill, mains input IEC connector and a large mains on/off rocker switch along with a small sticker indicating a universal mains input voltage of 115VAC to 230VAC make up the back panel. The front face of the power supply contains a small exhaust grill that will introduce a little warm air back into the enclosure along with the modular cable connector panel and captive cable exit port. There isn't any cable protection on the exit port but the metal edge is rounded and smooth and the cables and braided sleeve are firmly held in place with a cable tie just inside the power supply housing to prevent cable movement so damage won't be a problem. The modular connector panel is colour coded to assist in the wiring up process; 8 pin red connectors for the PCI-E cables, 6 pin black connectors for peripherals and a 8 pin black connector for the EPS12V cable.

The side panel most often visible is covered with a good quality label in silver and black with the Thermaltake logo and power supply wattage clearly shown along with a 80 Plus Silver logo. The fan grill is pressed from the metal enclosure which does away with the need for a separate metal wire type grill. The underside of the power supply carries a comprehensive specification label that includes the specification table, agency conformance marks and the usual warning about the dangers of opening up the power supply.

 

 

 

The captive cable set consists of a 24 pin motherboard connector and a 4+4 pin ATX12V/EPS12V connector, a sensible configuration that most users will definitely need. It's worth noting here that the motherboard connector doesn't split for use on older 20 pin motherboards but that facility just isn't needed on a 1350W power supply. The captive cable set is well made with plenty of connectors available and what's nice to see is six 8 pin PCI-E cables that use the full set of eight cables, no links or doubling up of wires into a single connector. In order to make up the full complement of eight PCI-E connectors Thermaltake have included two unbraided 4 pin peripheral to PCI-E adaptor cables which is a little disappointing but I imagine they'll very rarely be needed.

 

 

The 140mm cooling fan is a Thermaltake TT-1425B manufactured by Yate Loon with a part number of D14BM-12(L-SSS); a good quality 12VDC fan with a maximum speed of 1400RPM, air flow of 62.0CFM and a reasonably quiet noise level of 29dB.

 

The printed circuit board is a little untidy and cluttered in places but with 1350W, even with the extra length, there's not much room. Two independent +12V power supplies can be clearly seen and this is hinted at by the specification table which shows 12V1 supplying the 3V3 DC to DC convertor and 12V2 the 5V DC to DC convertor judging by the combined wattages. This power supply is manufactured by CWT and uses Nippon Chemi-Con 105°C rated electrolytic capacitors as stated on the packaging.

 

The Thermaltake Toughpower 1350W is well packaged with a good set of accessories. It's a little untidy internally but the visible soldering is satisfactory and they've had to squeeze a lot in there but it shouldn't be a problem. Let's have a look at the specification and features then see how well it performs.

Testing:

For more information on how we test our power supplies, please browse our testing methodology.

 

Short Circuit Protection:

I short circuited the 3V3, 5V0 and the 12V rail(s) in turn. The power supply did shut down, and once the short was removed and the unit switched off for at least one second, resumed normal operation. Although listed here at the beginning of the testing section, I tend to leave this test until the very end, in case it doesn't quite go to plan.

 

DC Output Voltage Load Regulation:

 

For the purposes of showing the results I have treated the 12V1 and 12V2 rails as a single rail. The measured voltage of both rails was virtually identical and the 12V load split approximately 50/50 across 12V1 and 12V2.

The Thermaltake Toughpower 1350W power supply produced an excellent set of results in this section. The power supplies ability to maintain the major rails at a more or less constant voltage from zero to full load is particularly impressive. No problems here, so let's move on.

The Thermaltake Toughpower 1350W is certified 80 Plus Silver which requires 85%, 88% and 85% efficiency at 20%, 50% and 100% DC loading with a power factor of 0.9 or greater at 50% DC loading. Power factor levels are rarely a problem, as is the case here, and the Thermaltake Toughpower 1350W gets closer than most to the efficiency requirements, 88%, 87% and 84%, following the OCC power supply testing methodology.

Lower power factor levels and better efficiency from a 230VAC supply but still very good.

Once again an excellent set of results from the Thermaltake Toughpower 1350W but what about electrical noise on the rails? Let's move on and take a look.

 

AC Ripple On DC Outputs:

 

I have consistently found the AC ripple levels on the DC rails to be more or less equal with an 110VAC or 230VAC mains supply. The results given below are for 230VAC only but I will continue to check the levels at 110VAC during testing and publish them below if there are any significant differences.

 

AC ripple/noise on the +3V3 rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

 

AC ripple/noise on the +5V0 rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

 

AC ripple/noise on the +12V rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

 

AC ripple/noise on the -12V rail at 230VAC

Oscilloscope settings: Amplitude = 5mv/div, Timebase = 5mS/div

The Thermaltake Toughpower 1350W produced a satisfactory set of results in this section with the noise levels on all the DC rails well inside the limits set down by the ATX12V specification.

Testing:

Temperature, Noise Levels and Fan Speeds:

I am not going to give a pass or fail in this section, as the ATX12V V2.2 does not really have any references on which to base a decision.

Temperatures are purely for information only, as there are too many variables involved when installed in a case, which, by the way, it wasn't. Ambient temperature, processor cooling efficiency and case cooling fans all play their part on the temperature of the air entering the power supply, and consequently the temperature of the air leaving it. No valid conclusions can be made from this test.

The Thermaltake Toughpower 1350W remained cool and relatively quiet at all times. Fan noise is of course subjective but it remained very low at 50% DC loading and a noticeable higher when the fan speed hit 1300RPM at full load which is to be expected.

Conclusion:

 

Price Per the Watt:

Power Supply Thermaltake Toughpower 1350W at $354.99 = $0.26/Watt (10-2011)

 

The Thermaltake Toughpower 1350W power supply performed very well throughout testing. The voltage regulation is excellent and in combination with satisfactory DC noise levels means good quality DC from zero to full load. It's claimed 80 Plus Silver certification is backed up by a good set of results following the OCC power supply testing methodology that gets as close if not closer than other power supplies in this class.

Electrically the Thermaltake Toughpower 1350W power supply is very hard to fault. The packaging, box contents and build quality are all good but it's only real problem is price, as it's too expensive. There aren't too many good quality 1350W power supplies available, but with the Enermax EMR1350EWT available for nearly $80.00 less and the possibility that a 1200W power supply may just suffice it's price tag is hard to justify. If you are in need of a 1350W power supply and don't mind paying a premium then the Thermaltake Toughpower 1350W power supply comes highly recommended.
