The Sapphire Radeon HD 2900XT (100201SR) closely follows AMD's HD 2900XT reference design and with that said the GPU and memory cooler found on the R600 is made out of copper and uses dual heatpipes to effectively dissipate the heat. Covering the HD 2900XT cooling solution is a red translucent Lexan cover, which covers nearly the entire PCB. At the back corner of the PCB is a 6-pin PCI Express and 8-pin PCI Express power connector. With this power-hungry graphics card two of the traditional 6-pin PCI-E power connectors will allow the HD 2900XT to function, but Windows users wishing to take advantage of ATI Overdrive for GPU overclocking will need to use both the 6-pin and 8-pin connections. There is no included 8-pin PCI-E power adapter, but many new power supplies such as the SilverStone Olympia OP650 already offer an 8-pin interface. This 512MB graphics card pulls about 215W therefore for a single HD 2900XT AMD recommends at least a 550W power supply, but a 750W power supply or greater is recommended.
