Thermaltake 1200W

1. Introduction

Thermaltake's devotion to innovative products shows itself once more with the arrival of the first ever 1200Watt power supply. The press release made an impact among users since for the first time, such a high powered power supply was announced onto the market. But why would someone need such a power supply, when most needs can be covered with a good 600W PSU? The answer lies in the recent arrival of next generation video cards, sporting Nvidia's 8800GTX and ATI's R600 GPU chipsets.

- Thermaltake Toughpower 1200W

Thermaltake Technology launched a 1200W as well as a 1000W product back in February 2007. The new additions are the response to the demands for higher power from both ATI and Nvidia graphics card that allows for unprecedented graphics realism and image quality.  Today’s high-end graphics cards will draw as much as 300W of power alone and with the popularity of multi graphics card configurations, users are expected to allocate aside at least 600W just for graphics cards.

Toughpower 1000W and 1200W will both feature three industry first 8-pin PCI-E connectors as well as three original 6-pin PCI-E connector configurations to support the Quad GPU system setup.  The 8-pin PCI-E connector is the next generation standard power connector for both ATI and Nvidia high-end graphics cards; it is downward compatible with the existing 6-pin PCI-E connector with an 8 pin to 6 pin converter. Hence, even though there are only 6-pin sockets available on the graphics cards, Toughpower 1000W/1200W can still run Quad GPU systems with no problem.

Unlike competing power supplies with only one or two 12V rails, four dedicated 12V rails, tightly regulated voltage (±3%) and Active PFC found on Toughpower, provide unparalleled reliability and stability.  The use of industrial-grade voltage controllers and on time control enables high-efficiency across all rails that exhibit up to 87% efficiency even under high-loads. This significantly lowers operating cost in addition to lowering thermal overhead, especially for users who operate their PC continuously.

Toughpower 1000W and 1200W both comply with the most recent Intel ATX 12V V2.2 for desktop and EPS 12V V2.91 for workstation or server platforms. On top of the three 6-pin PCI-E and three 8-pin PCI-E connectors, eight SATA power connectors and eight Molex connectors present a full array of future hardware upgrades. Cable Management feature eliminates clutters inside the chassis for great system airflow and improved thermal management. Ultra-quiet dual ball bearing 14cm fan with automated thermal control only increases fan speed when needed and maintains lowest noise level during idle or low power usage status.

Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP) and No Load Operation Protection are all the standard safety protection features found on each and every one of Thermaltake's power supplies.

- Features

  • Stable 1200W continuous output (at 50℃ operating environment)
  • Four independent & dedicated +12V rails (12V1,12V2,12V3,12V4) provides superior performance for PC system. (combined loading of 99A)
