1U Flex ATX 400W 80 Plus Gold

Dimensions (D x W x H)

165 x 81.5x 40.5mm

Efficiency
The minimum efficiency of power supply should be over than 87% under the maximum and
20% load and should be over 90% under the half load. Load measurements are performed at
115VAC/230Vac input.
The PF should be over than 0.9 under 20% load at 115VAC.

It is better to meet the 80 plus requirement .as the web site as follow:

Input Specifications
1-1. Input condition:

1-2. Inrush Current
Maximum inrush current from power-on (with power on at any point on the AC sine) shall be
limited to the peak surge current of the input line cord, bridge diode, fuse and EMI filter
components according to I2t. Receptive ON/OFF cycling of the AC input voltage shall not
damage the PSU or cause the input fuse to blow.

Output Specifications
Output Voltage and Ripple Noise Requirements

Note:

1). The output voltage should be measured at output connector terminals.
2). The output Ripple Noise should be tested with 10 F of tantalum and 0.1 F ceramic
disk capacitors to simulate system loading.
