The quality of the matt black textured paint job on the Thermaltake Toughpower Grand 1200W power supply is excellent.
The rear face of the power supply utilizes the commonly used hexagonal hole grill along with the usual IEC mains input connector and mains on/off switch. The panel to the right of the mains on/off switch lights up red to reveal the word "Thermaltake" when the power supply is operational. The front face of the power supply showing the modular cable connectors, red for the PCI-E graphics card cables and black for peripherals. What is nice to see here is dedicated 8 pin connectors for 8 pin PCI-E cables so no links, 8 pins for 8 wires. The captive cable set, sleeved all the way into the power supply, leaves the power supply via a plastic insert so no chance of cable damage from sharp metal edges.
Not much to see on the side panels apart the red stripe that runs around power supply enclosure; this will be the view from most cases that allow the power supply to be seen through a window.
The hexagonal holed fan grill, with a Thermaltake badge at its center, is part of the enclosure body which eliminates the need for a separate wire grill. The base of unit carries a comprehensive specification label. There's something strange about the specification table here; two 12V rails, one rated at 45A and the other at 85A. This only makes sense if there are two current limited 12V rails with 12V1 supplying the 3V3 and 5V0 DC to DC convertors, hence the reduced capacity to 45A, the other 85A reserved for a stronger +12V2 rail, but it's difficult to find out without ripping the power supply apart!
The captive cable set consists of a 20/24 motherboard connector, a 8 pin EPS12V connector and a 4+4 pin ATX12V/EPS12V connector which is fine but the need for two 8 pin connectors is rare so would it perhaps of made more sense to make the 8 pin EPS12V connector modular? The modular cable set is extensive and on the whole well put together apart from the 4 pin peripheral to 4 pin floppy disk adapter cable which is unsleeved but to be honest it's rarely needed. Four of the six PCI-E cables are single 8 pin to 8 pin cables which is a nice touch that utilizes all 8 wires, doesn't daisy chain another connector or use links for the extra ground connections that's often seen on 6 wire cables that are used for 8 pin PCI-E connectors. Thermaltake have however included two PCI-E cables with a daisy chained 8 pin connector in order to make available the specified eight 6+2 pin PCI-E connectors from the six PCI-E sockets available on the power supply.
The cooling fan of choice this time around is a Thermaltake TT-1425 which is manufactured by Yen Sun Tech under their model number YD121425HB with a 12VDC rating at 0.54A. This 140mm fan with the notches in the blade end is "flower" shaped and designed to keep noise to a minimum. The printed circuit board is well laid out and uses quality 105°C electrolytic capacitors by Nippon Chemicon.
The Thermaltake Toughpower Grand 1200W packaging is once again of high quality and includes an excellent set of accessories. The build quality is on a par with other power supplies in its class, but how will it perform? Let's move on and see.
