NOTE: Noise test should be measured with 20 MHz bandwidth frequency oscilloscope. The output terminal shall add a tantalum capacitor of 10uF in parallel with a ceramic capacitor of 0.1uF.

Remote On/Off Controlled mode

The PSON# signal is required to remotely turn on/off the power supply, PSON# is an active low signal that turns on the output power rails. When this is not pulled low by the system, or left open, the outputs (except the +5VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply.

• TTL level
  • “H” 2.0 V – 5.25 V
  • “L” 0.0 V – 1.0 V

Regulation

The cross regulation defined as follows, the output regulation should be within the specified range.

Rise Time

• DC output rise time is less than 20 mS at nominal line and full load.

+5V DC / +3.3V DC Power Sequencing

The +12V and +5V output levels must be equal to or greater than the +3.3V output at all times during power-up and normal operation. The time between any output of + 12V and +5V reaching its minimum in-regulation level and +3.3V reaching its minimum in-regulation level must be ≤ 20mS.

Hold-up Time

PG output maintains at least 16mS is 40% 1oad after power off which hold within para 3.1 under 115V/60Hz and 230V/50Hz condition.

5VSB

5VSB is requierd for the implementation of PS-ON described above. 5VSB is a tandby voltage that may be used to power circuits that require power input during the powered-down state of all power rails. The 5 VSB pin should deliver 5V ± 5% at a minimum of 3.0 A for PC board circuits to operate. Conversely, PC board should draw no more than 3.0A maximum form this pin. This power may be used to operate circuits such as soft power control.

PG-OK

PG-OK is a power good signal and should be asserted high by power supply to indicate that the +5 VDC and +3.3 VDC outputs are above the under-voltage thresholds of the power supply. When this signal is asserted high, there should be sufficient mains energy stored by the converter to guarantee continuous power operation within specification. Conversely, when either the +5VDC or the +3.3VDC output voltage falls below the under-voltage threshold, or when mains power has been removed for a time sufficiently long so that power supply operation is no longer guaranteed, PG-OK should be deasserted to a low state. See Figure 1 for a representation of the timing characteristics of the PG-OK, PS-ON, and germane power rail signals.

3.3V Sense

• A default 3.3V sense line should be implemented pin 13 of the connector.

Capacitive Load

The power supply should be able to power up and operate normally with the following capacitances simultaneously present on the DC outputs.

Protection

Input Protection

In primary circuit of the power supply , a protected fuse is inserted. Only internal fault of the power supply will cause the fuse blown. Any overload or short circuit at DC output will keep from fuse brown or fire hazard.

Output Protection

Under voltage protection

The +12V/+5V/+3.3V DC output are protected against the under voltage condition range value can’t be exceed 10.3~11.0V at 12V terminal and 3.3~3.7V at 5V, 2.0~2.4V at 3.3V.

Over Voltage Protection

The +12V/+5V/+3.3V DC output are protected against the over voltage condition. Maximum value can’t be over 15.6V at 12V terminal and 7.0V at 5V, 4.3V at 3.3V.

Over Power Protection

The power supply can be used electronic circuit to limit the output current against exceeding 30-70% of surge output power or protected against excessive power delivery since short circuit of any output or over total power at high line.

Short Circuit Protection

• Short circuit placed on +5V,+12V,+3.3V,-12Vwill latch off. +5VSB will auto-recovery.

Over Current Protection

Current protection should be designed to limit the current to operate within safe operating conditions.Over current protection schemes where only the voltage output that experiences the over current event is shut off may be adequate to maintain safe operation of the power supply and the system; however, damage to the motherboard or other system components may occur. The recommended over current protection scheme is for the power supply to latch into the shutdown state. The setting of over current protection for each output rail is as following

• +5V is less than or equal to 22~30A..
• +3.3V is less than or equal to 22~30A.
• +12V is less than or equal to 92~120A

Over Temperature Protection

This power supply includes an over-temperature protection sensor, which can trip and shut down the power supply at 75℃ ±10℃.

Start Stability

No Load Start

When power is applied to PSU with no load connected or under minimum load connected, neither damage to power supply nor hazards to users will occur.

Power Good Signal

A TTL compatible signal for the purpose of initiating an orderly start-up procedure under normal input operating conditions. During power up, this signal is asserted ( low ) until +5V is under regulation and AC reaches min.line specification range. After all voltage are going appropriate level, the system may have a turn on delay of 100mS, but no greater than 250mS. During power off the signal should go to low level before +5V is out of regulation. The low level is 0 to 0.8V and high level is 4.75 to 5.25V.

POWER SUPPLY CONNECTOR OVERUSE DEFINITION

A single PCIe 8pin cable and connector’s maximum current rating is 12.5A, which is 150W (+12V x 12.5A). So SilverStone’s warranty will not cover damages or malfunction resulting from the use of a graphics card or expansion card with a single PCIe 8pin connector that exceeds standard 225W total power draw (150W from PCIe 8pin connector + 75W from PCIe motherboard slot). 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.
