Nexus NX-3500 Real Silent Power Supply
The Nexus NX-3500 Special Edition is the latest edition to the Nexus Real Silent power supply series. The Nexus NX-3500 Special Edition is equipped with a large 12 cm fan which provides sufficient airflow to cool the power supply at very low speed and at a very low noise level. This power supply configuration produces only 19.2 dB(A) in idle mode and will be inaudible when mounted in a computer system as the fan will be located on the inside of the computer case. The NX-3500 has longer power cables and is SATA ready airflow, this quiet power supply is well-suited for today's 3 Ghz and above quiet pcs.

(1) +3.3V & +5V total output not exceed 220Watt. When +3.3V is load to 28A, the +5V maximum load is 25.5A. When +3.3V is load to 21.2A, the +5V maximum load is 30A.
(2) +3.3V & +5V & +12V total output not exceed 330Watt
Specifications:
- Remote ON/OFF Control: This power supply shall accept a logic open collector level which will disable/enable all out put voltage (excluding +5V standby).
- Output voltage hold-up time: 10.0mS minimum: at 230V / 50 Hz
- Operation at no load: This power supply will be capable of being operated with no load on any or all outputs without damage.
- Over voltage protection:
- +5V : 6.5V (max.)
- +3.3V : 4.6V (max.)
- +12V : 15.5V (max.)
- Over-current test values: (maximum load)
- +3.3V : 81A (max.)
- +5V : 65A (max.)
- +12V : 30A (max.)
- Short current protection: A short circuit at any output shall cause no damage to this power supply nor blow the primary fuse.
- Output risetime: The cold-start enable output voltage risetime of all outputs shall be measured with maximum load on all outputs. Risetime (10-90%):
