Thermaltake Toughpower 1000W Review - Updated

Closer Look:

You will see from the photograph that the Thermaltake Toughpower 1000W is a little longer than the average power supply at nearly 8 inches long and this will need to be taken into consideration when lining up a case. The user manual tells me the power supply has a "special Hi-Tech Black coating", I don't know whats hi-tech about it but it, does look good. The hardwired cables shown at the rear include the 20/24 pin motherboard connector, one 4+4 pin ATX12V connector and a EPS12V 8 pin connector.
















The front panel showing the honeycombed grill exhaust, IEC mains input connector and a nice large mains on/off switch. The rear panel showing the hardwired cable port and the modular cable connectors. The modular cable sockets and the corresponding modular cable connectors are all colour coded, black for peripherals, blue for graphic card one and red for graphic card two auxillary power. The attached label shows which 12V rails are utilised.



One side of the power supply bears a good quality aluminium Toughpower label and on the other side is a test label.



The Thermaltake Toughpower 1000W uses a large 140mm cooling fan which is protected by a grill that is actually part of the case and gives a better quality finish, in my opinion, than the usual screw attached safety grill. The other side of the power supply shows a comprehensive specification label.



Hardwired cables and the full set of modular cables with colour coded plugs as previously stated.



The cooling fan is a large 140mm Thermaltake TT-1425B rated at 12VDC 0.7A manufactured by Yate Loon Electronics.


This power supply like many others of 1000W or above is actually two switched mode power supplies in one box. The two power supplies produce one high current 12V rail each which is then distributed to supply two of the four 12V rails each and either the 3V3 or 5V0 via DC to DC converters.


The heatsinks are highly finned to increase their surface area and improve heat dissipation. The main capacitors are rated at 85°C. I couldn't find any manufacturers marks without totally dismantling the printed circuit board. What is clearly printed on one corner of the circuit board is Gigabyte, so maybe this board is also used in one of their units?



The Thermaltake Toughpower 1000W is a good looking, well built unit. Let's hope it performs...
