PowerColor launched its second Radeon HD 7750 graphics card, a Go! Green variant. Models of this series tend to be energy-efficient (with slightly lowered voltages, reducing power draw), while maintaining reference clock speeds. Another striking feature of Go! Green variants is their silent passive-heatsink that cools the GPU and VRM. To maintain high temperature tolerance, and energy-efficiency, PowerColor tends to employ high-grade voltage regulation components on their Go! Green cards. In case of this card, it is said to utilize PowerPAK SO-8 MOSFETs, shielded chokes, and conductive-polymer capacitors.

The card sticks to reference clock speeds of 800 MHz (core) and 1125 MHz / 4.50 GHz effective (memory), packs 512 Graphics CoreNext stream processors, and 1 GB of GDDR5 memory over a 128-bit wide memory interface. The cooler is similar to the one featured on previous-generation Go! Green cards from PowerColor, it consists of a dense aluminum fin heatsink, to which heat is conveyed by copper heat pipes that draw head directly off the core. Heat dissipation happens passively. Expect the card to charge a tiny premium over other Radeon HD 7750 cards in the market.

TUL Corporation, a leading manufacturer of AMD graphics cards, announces new mainstream products added to the Go! Green series: the PowerColor Go! Green HD5670 and Go! Green HD5570. Both new graphics cards take advantage of the Go! Green series features inclyding stealth like silence and low power consumption. The cards feature no external power connectors, enabling a power efficient and silent gaming and entertainment solution.

Both the Go! Green HD5670 and Go! Green HD5570 features an ultra-efficient passive cooling solution dissipating excessive heat with minimal noise. With extremely thin cooling fins that fully cover the GPU and memory, it can reduce the temperature efficiently through the added copper heat pipes.

TUL Corporation, a leading manufacturer of AMD graphics cards, announces the latest HD5450 series and wraps with Go! Green features in this newest product lineup. PowerColor HD5450 Go! Green series offers environmentally friendly and power efficient for consumers. It features stealth like silence and low power consumption, providing a cost efficient and silent entertainment solution.

With full range support of DirectX 11 and Windows 7, Go! Green HD5450 series provides a stunning high-definition entertainment experience from Blu-ray playing or other HD resources. Also, with the support of ATI stream technology, Go! Green HD5450 allows GPU to work with CPU to accelerate applications beyond just graphics, but also enables a faster and easier daily application experience.

Many of you have probably read the press release of the Radeon HD 5750 from Powercolor without the usually required PCI-E power connector. The card runs at the exact same specs as a reference card of the same model, but lacks both the additional power requirements and active cooling. Powercolor has placed a dual slot, passive cooling solution with copper heatpipes and aluminum heatsinks unto the graphic card. The DVI connectors are of black color and Powercolor has also kept the additional DisplayPort and HDMI connectivity we have seen on reference models of the graphic card. Here are some close-up pictures of the card:
