Sources say Quanhan will launch MEGA Ti 1650W high-end power supply, using gallium nitride technology.

Thanks to CTOnews.com netizen OC_Formula for the clue delivery! CTOnews.com November 12 news, Cowcotland reported that Chuan Han's next 1650W MEGA Ti high-end power supply will use gallium nitride technology, but the cost of this technology is still very high.

Thanks to the inherent characteristics of gallium nitride devices, such as low parasitic parameters and high switching speed, the use of gallium nitride devices in products can reduce the loss of the system and increase the working frequency, thus reducing the size of passive components and radiators of the system. make the system achieve higher power density and higher efficiency.

Compared with silicon, gallium nitride has higher critical electric field, unique and excellent dynamic on-resistance and lower capacitance. Therefore, gallium nitride devices have been widely used in products such as chargers and pen adapters.

For the use of gallium nitride in the field of PC power supply, from a technical point of view, there is no problem with the application of gallium nitride devices in the field of PC power supply, but from an engineering point of view, we also need to comprehensively consider the system cost, industry specifications and other factors.

In fact, gallium nitride devices are already used in some PC power products. CTOnews.com inquiry found that the current pirate ship using gallium nitride transistor AX1600i titanium power supply JD.com shows for 3399 yuan, more than 2 yuan per watt, the cost is higher. It is believed that with the reduction of device cost and the development of industry specifications in the future, gallium nitride devices will have more applications in the field of PC power supply.
