SilverStone Strider Gold S
ST1500-GS
ATX12V / EPS 12V Switching Power Supply
With Active PFC
80 PLUS Gold
PS/2
To meet the requirements of current and future desktop computers, SilverStone created the Strider Gold S
series power supplies. The Strider Gold S models are all new designs engineered to be the smallest, full-modular ATX
power supplies at any wattage levels.
The Strider Gold S series includes wattage range from 550W to 1500W for a great variety of applications.
With short depth designs, all models in the series are among the world’s smallest full-modular ATX PSUs.
In addition to 80 PLUS Gold level efficiency, the Strider Gold S PSUs are built to meet very high standards in
electrical performance with ±3% voltage regulation, ±3% ripple & noise, and high amperage single +12V rail.
Other notable features included are 24/7 40℃ continuous output capability, low-noise fan, and multiple sets of
PCI-E cables. For users looking for a power supply with faultless combination of compact size, performance,
efficiency, and quality, the Strider Gold S Series is the only choice.
1.1 AC input requirements
The input voltage, current, and frequency requirements for continuous operation are stated below.
1. AC INPUT
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

2.3.2 Definition
The ripple voltage of the outputs shall be measured at the pins of the output connector when terminated in the
load impedance specified in figure 1. Ripple and noise are measured at the connectors with a 0.1uF ceramic
capacitor and a 10uF electrolytic capacitor to simulate system loading. Ripple shall be measured under any
condition of line voltage, output load, line frequency, operation temperature.
2.3.3 Ripple voltage test circuit
2.4 Overshoot
Any overshoot at turn on or turn off shall be less 10% of the norminal voltage value, all outputs shall be within the
regulation limit of section 2.0 before issuing the power good signal of section 4.0.
2.5 Efficiency
Power supply efficiency 20% Loading / 87%，50% Loading /90%，100% Loading /87% at normal AC main voltage
(AC input 115V or 230V).
2.6 Remote ON/OFF control
When the logic level "PS-ON" is low, the DC outputs are to be enabled.
When the logic level is high or open collector, the DC outputs are to be disabled.

3.1 Over current protection
The power supply shall have current limit to prevent the +3.3V,+5V,and +12V outputs from exceeding the
values shown in the following Table.If the current limits are exceeded the power supply shall shutdown and
latch off.

3.2 Over Temperature Protection
The power supply will be protected against over temperature conditions caused by loss of fan coolng or
excessive ambient temperature. In an OTP condition the PSU will shutdown. When the power supply temperature
drops to within specifide limits, the power supply shall restore power automatically. The OTP circuit must have
built in hysteresis such that the power supply will not oscillate on and off due to temperature recovering condition.
3.3 Over-power protection
The power supply will be shutdown and latch off when output power within 105~150% of rated DC output.
Note: Assurance machine can work at low voltage,full load won't damage machine.
3.4 Under voltage protection
In an under voltage fault occurs, the supply will latch all DC outputs into a shutdown state when +12V,
+5V & +3.3V outputs under 85% of it's maximum value.
3.5 Over voltage protection
The over voltage sense circuitry and reference shall reside in packages that are separate and distinct
from the regulator control circuity and reference.No single point fault shall be able to cause a sustained
over voltage condition on any or all outputs.The supply shall provide latch-mode over voltage protection
as defined in Table.

3.6 Short circuit
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+12 VDC 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.
3.7 No load operation
No damage or hazardous condition should occur with all the DC output connectors disconnected from the load.
The power supply may latch into the shutdown state.
