Thanks to AMDвЂ™s Eyefinity technology, all 4 ports can be run simultaneously. The back panel connector has two mini Display Ports, a HDMI port, and a DVI port. To be honest, I donвЂ™t think youвЂ™ll need anywhereВ nearВ 450w. HIS recommends a 450W or greater power supply. The card is short enough to have the single 6-pin power connector mounted on the rear end. The card requires a single 6 pin power PCIВ connector. The fan draws air from inside the case and blows it out the back which is partly why thereвЂ™s such a large gap between the heatsink casing and the PCB.

For those unfamiliar, iTurbo is a software suite developed by HIS to optimize the fan speed for different load conditions. Instead of the HIS logo, the fan on the 7770 GHz edition now features the iTurbo symbol. As you can see in thisВ shot,В the heatsink is circular in shape. They both have the single 9 blade blue fan, and the black casing over the heatsink. The iCooler cooling solution on the 7770 GHz edition is similar in appearance to the 6770 Dirt 3 edition.

As always, please do not use the driver on the disk and download the latest version from AMD instead.

A 1GHz core clock is actually the reference design.ДЄccessories include a driver installation guide, a card installation guide, a VGA to DVI adapter, a HIS sticker, a utility disk, a simple guide on how to seat the graphics card, and the driver disk.

Also just as a FYI, every HD 7770 sold should be a вЂњGHz EditionвЂќ product, which simply means that the graphics card runs at 1GHz. The text at the bottom of the box lets us know that weвЂ™ve got the HD 7770 GHz Edition, but thatвЂ™s about it. ThereвЂ™s no mention that itвЂ™s the iCooler edition here. Here we get the typical HIS sword graphic packaging we all know and love. To be honest, I cringed when first saw the iCooler onВ theВ HIS 7770 as it seems more or less identical to AMDвЂ™s reference design however, if the HIS 7750 iCooler is any indication, the iCooler should do a fairly good job of keeping the 7770 iCooler cool as well. While the card itself is reference, HIS has included their custom iCooler solution with the 7770 iCooler weвЂ™ll reviewing today.

As with all the other Radeon HD 7000 series GPUs, the HD 7770 uses the 28 nmВ fabricationВ process, which reduces power consumption and heat output, while still maintaining extremely powerful graphics capabilities. Similar to the Radeon HD 7750, the Radeon HD 7770 relies on the same AMD Cape Verde GPU and is mainly intended to compete in the budget graphics arena.

However, this time around, weвЂ™ll be reviewing the more powerful HIS 7770 iCooler Edition graphics card, which as the name implies will be based off the AMDвЂ™s Radeon HD 7770. Today weвЂ™ll again be reviewing a HIS graphics card based off the AMD Radeon HD 7700 series and again itвЂ™ll come with HISвЂ™s iCooler custom cooling solution. Keep it iCoolerДЄ couple months back, we reviewed HIS 7750 iCooler Edition graphics card, which we found to be an excellent graphics card offering high performance-to-price ratio, low power consumption, and had a much better cooling solution than the one found on the reference design.
