reports PowerColor is working on the Radeon HD 5770 PCS++, a new graphics card geared towards overclockers. The card has the same frequencies and cooling solution as the company's HD 5770 PCS+, but has a redesigned PCB with better VRM for extra overclocking potential. This new card is expected to retail for about 10EUR ($15) more than the Radeon HD 5770 PCS+, which is currently around $195.
The PowerColor HD 5770 PCS++ borrows its PCB design from the PowerColor HD 5770 Go! Green, which we recently reviewed. To do away with the 6-pin auxiliary power connector, the Go! Green card relied on a high-efficiency digital PWM circuit with three vGPU and two vMem phases, driven by a Volterra VT1165 voltage controller which supports software voltage control. From the looks of it, the PCS++ reuses the same PCB, but with the 6-pin power connector in place for added power. Despite the lack of this connector, and having passive cooling, the Go! Green card managed GPU and memory overclocks of 10% and 25%, making us expect even higher with this card. Its cooling system includes a GPU cooler made by Arctic Cooling, with independent heatsinks over the memory and VRM chips.
