Server Power Roundup: Wolfspeed Gen-6 SiC and TDK Caps Enter 3300W PSUs
2026-10-06 · Compiled by Best IT Parts from public industry reporting
Recent industry coverage highlights a cluster of component wins inside high-wattage server power supplies. A roundup dated 6 October notes that Wolfspeed's sixth-generation SiC devices have entered a major-brand 3300W server PSU, while TDK 1820F high-voltage capacitors now appear in a leading 3300W server PSU design. Both point to the same trend: silicon-carbide switching and high-voltage bus capacitors are moving from flagship designs into mainstream rack power.
On the control and drive side, a major-brand 3kW high-power PFC stage is reported to use a TI isolated gate-drive solution, and a 72W 1/8-brick isolated DC-DC module has been analysed as a reference design. The 1/8-brick form factor remains a standard building block for intermediate bus conversion inside servers and telecom equipment, so its evolution is worth tracking for anyone specifying or servicing such hardware.
Smaller-format news in the same roundup includes a teardown of a 30000mAh LiFePO4 portable power station and a comparison of five third-party chargers delivering high-power PPS to a current flagship phone. A BULL charge-and-discharge cable bundle also received domestic 3C certification during the same period.
For buyers of server power supplies and IT accessories, the takeaway is a supply chain steadily shifting toward SiC switching, isolated drive and higher-voltage bus capacitors at the 3kW-plus tier, the same tier that drives demand for replacement PSUs and component-level spares.
