GaN Systems, a global leader in GaN (gallium nitride) power semiconductors, and xFusion Digital Technologies (xFusion), a leading global provider of computing power infrastructure and services, introduced the xFusion 3 kW PSU, the world’s first 100 W/cubic inch with 80 Plus Titanium efficiency solution.
The increasing demand for more data and power combined with sustainability initiatives are driving change in the data center industry. The switch to GaN System’s power transistors has demonstrated increased performance for products with power levels from 800 Watts to 6 kW delivering substantial operating, financial, and environmental benefits.
Key features of xFusion 3 kW PSU :
- High power density at 100 W/cubic inch
- 80 Plus Titanium efficiency of 96%
- Compact design with dimensions of 68 mm x 183 mm x 40.5 mm
- Supports 90 V to 264 V DC voltage and 180 V to 300 V AC voltage input, 12 V output
“Customers implementing GaN Systems’ power semiconductors in their PSUs are seeing a continual increase in PSU power density from 45 W/cubic inch to 63 W/cubic inch, 82 W/cubic inch, and now to 100 W/cubic inch,” said Jim Witham, CEO of GaN Systems. “With these power density breakthroughs and efficiency improvements, the value proposition of GaN is undeniable, and we will see more PSU companies offering these solutions.”
GaN is gaining ground in data center PSUs. With the growth of the data center sector worldwide, operators are focused on profitability and reducing their CO2 emissions. For each set of 10 racks in the data center, GaN-based PSUs can increase profits by $3 million, reduce the cost of operating a data center and CO2 emissions output by more than 100 metric tons per year. Companies designing with GaN are doubling the power density of legacy PSUs, reaching power densities up to 100 W/cubic inch with 96+% efficiency, resulting in power supplies half the size and half the power loss compared to silicon-based power supplies.
