Nexus NX-4090 Real Silent ATX 400W


Huippuhiljainen virtalähde uutuus Nexukselta.
Specifications: Remote ON/OFF Control: The 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:

15.0mS minimum: at 115V / 50 Hz

12.0mS minimum: at 230V / 50 Hz.

Operation at no load: The 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.)

+12V1 : 15.5V(max.)

+12V2 : 15.5V(max.)

Over current protection: There shall be protection from an output over-current event. The power supply may shutdown from such an event and require power-on restart. Testing consists of application of the listed over-current value with maximum load on all other outputs. Over-current test values: (maximum load)

+3.3V : 80A(max.)

+5V : 68A(max.)

+12V1 : 45A(max.)

+12V2 : 45A(max.)

Short current protection: A short circuit at any output shall cause no damage to the power supply nor blow the primary fuse. The power supply may shut down in the event of a short circuit and require power-on restart. A short circuit consists of application of a test resistance of less then 0.05 ohms at each output with maximum load on all outputs.

Output risetime: The cold-start enable output voltage risetime of all outputs shall be measured with maximum load on all outputs. Risetime (10-90%):

+3.3V 20mS (max.)

+5V 20mS (max.)

+12V 20mS (max.)

+12V 20mS (max.)

+5Vsv 20mS (max.)

Output overshoot: No output voltage shall overshoot or generate spikes at turn-on or turn-off, during momentary power loss, output short, or realistic input voltage or output load changes. Overshoot is defined as any output that exceeds the voltage tolerance plus or minus an additional 5%.

Efficiency: Overall efficiency must be 70% min. measured at normal AC mains voltage and frequency with maximum loads on all outputs.

Power good signal: 115/230V (full load): 100-500mS

Temperature range:

operating 0oC~50oC

storage -20oC~+65oC

Relative Humidity: 90%

Safety requirements: TUV EN60950, NEMKO + CB REPORT, IEC 60950, UL 60950

Dielectric strenght: Primary to frame ground: 1800 Vac for 1 sec. Primary to secondary: 1800 Vac for 1 sec.

Insulation resistance: Primary to secondary: 20 Meg. ohms min. Primary to frame ground: 20 Meg. ohms min.

Ground leakage current: The power supply ground leakage current shall be less than 3.5mA

Sanokaas mahdollisimman hyvä konepaketti 1000€:lla

Mukaan ei tarvitse:
- Hiirtä + näppäimistöä
- Kaiuttimia
- Näyttöä

Ja myös sellainen kauppa, jossa ne kokoaa sen koneen ku mä en osaa
