PC power supply
Thanks to state-of-the-art technological advances, the overall power consumption of a PC’s central processing unit (CPU) continues to decline. Though this development is positive, it also introduces new obstacles for the PC power supply to bypass. What’s required today: a small form factor for OEM PC power and better price performance for the DIY (do-it-yourself) market.
Infineon fulfills all your PC power supply needs. We even offer a selection of proven reference designs to help valuable customers like you develop the best-possible computer power supply solutions. Choose PC power supply semiconductors from Infineon and reach your targets – from greater efficiency to lower overall system cost.
