Server Power Supply 300W
The TOPOWER TOP-300W1U-PFC is a single 300W server power supply built for 1U industrial chassis. It accepts 100-240V input and uses forward circuitry with OVP, OCP and SCP protection on all outputs. The unit suits integrators who need a compact, reliable ATX12V/EPS12V source for embedded or rackmount systems.
300W Output and Rail Limits
The +12V rail delivers 20A while the +3.3V and +5V rails each provide 22A, with a combined minor-rail ceiling of 120W. A 3.3V auxiliary line supplies 3A for standby functions. This capacity covers typical single-socket server boards with modest drive counts, but leaves no headroom for high-wattage CPUs or multiple GPU accelerators.
Sliding Main Connectors and Dual Fans
The 20/24-pin and 4/8-pin main connectors use a sliding design that eases installation in tight 1U bays. Two 40mm fans run under thermal control with Silent Control Technology, reducing acoustic output at low load. Builders who need redundant supplies or modular cabling beyond the fixed leads must look elsewhere.

商品問答
Will this 300W unit run an older motherboard that still uses a 20-pin main power connector?
Yes, the sliding main connector fits both 20-pin and 24-pin motherboard sockets.
How can I verify the 12V rail is delivering its rated 20A after installation?
Measure the +12V output under load with a multimeter; it should stay within ATX12V / EPS12V tolerance.
Does the box include the 4/8-pin CPU power cable or must I buy it separately?
The 4/8-pin CPU connector is built into the sliding main cable assembly, so no separate cable is required.
