Thermaltake Toughpower 1350W Power Supply Review

» Discuss this article (4)

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.
