Thermaltake Toughpower XT 850W Power Supply Review

Closer Look:

The Thermaltake Toughpower XT 850W power supply is housed in a good quality standard ATX dark green painted case.

 

 

 

 

 

 

 

 

 

 

 

 

The back panel sports the usual mains input IEC connector, mains on/off switch and honeycombed exhaust grill along with the FanDelayCool three position slide switch unique to Thermaltake, which I will cover later. The modular cable connector sockets are all neatly arranged on the back panel, red for PCI-E connectors and black for peripherals. The only hardwired cable on the Thermaltake Toughpower XT 850W is the 20/24 pin motherboard connector cable, which explains the addition of a modular CPU power connector not seen on most modular power supplies.

 

 

One side of the power supply is covered with a printed aluminium label with power supply make and model and power supply wattage. This side of the power supply also includes the three S.P.T. indicator lights, which is covered later. This label, by the way, always causes problems on Thermaltake power supplies because it hides two of the case screws and once the corners have been lifted it never looks the same again. The other side of the power supply contains a production line test label.

 

 

 

The fan grill is pressed into the steel case so the usual screw fixed fan grill isn't needed. The top of the power supply is taken up with the specification label using a black and silver theme with a splash of color for the manufacturer, model, 80 Plus and five year warranty logos.

 

 

The Thermaltake Toughpower XT 850W uses only one hardwired cable for the 20/24 pin motherboard connector. This cable leaves the power supply via a grommeted port to protect the wires from sharp edges and is fully sleeved almost, but not quite, all the way into the power supply. A comprehensive set of modular cables is supplied with color coded plugs and labels to help during installation.

 

 

The accessories also include two 8-pin PCI-E to 6-pin PCI-E adaptor cables for use in dual graphic card installations and a 4-pin to 4-pin extender cable should the original fall short. The kit also includes a noise damper gasket, mounting screws, case badge and four velcro straps bearing the Thermaltake logo to help tidy up the cables once installed.

 

The 140mm fan is the commonly used Thermaltake TT-1425B manufactured by Yate Loon. The printed circuit board looks a little untidy but everything is either sleeved, tied or fixed in place to help stop those annoying little noises. There is one extra connector here that wires up the S.P.T. indicator panel on the side of the power supply.

 

 

The use of three large heatsinks will help the Thermaltake Toughpower XT 850W dissipate the heat generated during operation. I was unable to see any manufacturers' marks on the electrolytic capacitors so I cannot confirm Thermaltake's use of Japanese electrolytics.

 

 

The Thermaltake Toughpower XT 850W power supply is well packaged with an excellent set of accessories. The overall build quality is very good, if a little untidy, but I'll forgive Thermaltake for that because 850W of power is a lot to squeeze into a standard ATX case. Let's see how it performs.
