AC input characteristics

AC input requirements
The input voltage, current, and frequency requirements for continuous operation are stated show in Table 1.

Table1

AC inrush current(cold start):
The power supply must meet inrush requirements for any rated AC voltage, during turn on at any phase. of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF cycling of AC, and over the specified temperature range .The peak inrush current shall be less than the ratings of its critical components (including input fuse, bulk rectifiers, and surge limiting device).

The +12V transient load slew rate is = 5.0 A/μs.

NOTES:

1. For example, for a rated +5 VDC output of 14A, the transient step would be 30% x 14 A = 4.2 A.
2. Output voltages should remain within the regulation limits of Section 2.1. and the power supply should stable when subjected to load transients per Table 3. from any steady state load, including any or all of the following conditions:

Protection:

Due to overvoltage, over power and short circuit, the protection function of the power supply circuit is self operated, and the power is self locked. There is no output at that time. When these reasons are removed, the power is restored to the normal output state when the power is restarted. (PSON# at least 1 second;
AC shutdown at least 4 seconds).

Over-power protection.
The power supply will be shutdown and latch off when output power within 110~150% of rated DC output.

   An output short circuit is defined as any output impedance of less than 0.1 ohms. The power supply shall shut down and latch off for shorting the +3.3 VDC,
   +5 VDC,or+12VDC rails to return or any other rail. Shorts between main output rails and +5VSB shall not cause any damage to the power supply.
   The power supply shall either shut down and latch off or fold back for shorting the negative rails.+5VSB must be capable of being shorted indefinitely,
   but when the short is removed,the power supply shall recover automatically or by cycling PS_ON#.The power supply shall be capable of withstanding a continuous short-circuit to the output without damage or overstress to the unit

If the current limits are exceeded the power supply shall shutdown and latch off. The damaged from repeated power cycling in this condition. -12V and 5VSB shall be protected under over current or shorted conditions so that no damage can occur to the power supply. All outputs shall be protected so that no damage occurs to the power supply under a shorted output condition.

Similarly, a graphics card or expansion card with dual PCIe 8pin connectors that exceed 375W total power draw (300W from two PCIe 8pin connectors + 75W from PCIe motherboard slot) will also not be covered under warranty.
• Peripheral (molex) or SATA connector’s maximum current rating is 5A, which is 60W (+12V x 5A) or 25W (+5V x 5A). Please ensure connected devices are operating under these limits. SilverStone’s warranty will not cover damages or malfunction resulting from usages exceeding these connectors and their associated cables.
• 24pin motherboard connector’s maximum current rating for its dual +12V metal pins are 5A each, which totals 120W (+12V x 5A x 2). Please ensure +12V drawing devices connected to the motherboard are operating under these limits. SilverStone’s warranty will not cover damages or malfunction resulting from usages exceeding these connectors and their associated cables.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
