Radeon HD 5970 Power Supply Design
Radeon HD 5970 power supply design
Radeon HD 5970 has continued to use Volterra solution just as previous high-end graphics cards, and the design is quite similar to that of Radeon HD 5870 – CPLA-3-50 inductor, VT1157SF power chip, and VT1165MF controller chip for GPUs, while using VT237WF power chip for the memory.
The utilization of high-quality components represents AMD’s uncompromised design regardless of expensive manufacturing cost.
