Thermaltake has launched three new power supplies under its Toughpower Gold series. The new models come in 550W, 650W, and 750W capacities and offer up a semi-modular design and 80 PLUS Gold efficiency ratings.

The new power supplies are rated at 87% to 92% efficient depending on the load and fall under the 80 PLUS Gold designation. Additionally, the PSUs offer a single rail design to deliver stable power to graphics cards and the processor. A semi-modular design has the 24 pin and 8 pin motherboard power connectors permanently attached and connection points for a variety of additional power cables. Thermaltake has gone for a flat cable design which should mean the cables are easier to route and hide behind the motherboard tray. Other features include high quality Japanese capacitors and a reportedly quiet 140mm fan that hits 18dB under typical loads.

The 550W offers two 8-pin PCI-E power connectors while the top end 750W version supports up to four 8-pin PCI-E power connectors meaning it can easily power CrossFire and SLI multi-GPU setups.

You can find more information on the Toughpower Gold power supplies on their respective product pages.
