1. AC input specifications
1.1 AC input voltage, frequency and current
Rating: 100V-240 VAC, 47-63Hz, 14-7A
The power supply must operate within all specified limits over the input voltage range. Harmonics distortion of up to 10% THD must not cause the power supply to go out of specified limits. Based on the minimum voltage and power transfer, the max current calculation is: Max Current ≥ (Watt / Efficiency) / Minimum Voltage.
| Parameter | Minimum | Normal | Maximum | Max. Current |
|---|---|---|---|---|
| Voltage (115V) | 90 VAC | 100-120 VAC | 132 VAC | 13A |
| Voltage (230V) | 180 VAC | 200-240 VAC | 264 VAC | 6A |
| Frequency | 47 Hz | 50 / 60 Hz | 63 Hz | N/A |
1.2 AC inrush current
The power supply must meet inrush requirements of any rated AC voltage, during turn on at any phase of 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 30/60A @ 115/230 VAC (25°C) per module when cold start and less than the rating of its critical components.
1.3 Input power factor correction (Active PFC)
The power factor at 50% load shall be ≥ 0.9 at 230V input voltage.
1.4 Input current harmonics
When the power supply is operated in 90-264Vac, the input harmonic current drawn on the power line shall not exceed the limits set by EN61000-3-2 class “D” and GB9254-2008 standards. The power supply shall incorporate universal power input with active power factor correction.
1.5 Dropout
An AC line dropout is defined as when the AC input drops to 0 VAC at any phase for any length of time. During an AC dropout of 18mS or less, the power supply must meet dynamic voltage regulation requirements up to 80% of the rated output load. An AC line dropout of one cycle or less shall not cause any tripping of control signals or protection circuits. If the AC dropout lasts longer than 18mS or the load is greater than 80%, the power supply should recover and meet all turn on requirements. Any dropout of the AC line shall not cause damage to the power supply.
2. DC output specification

2.2 DC voltage regulation, ripple and noise
The power supply output voltages must stay within the following voltage limits when operating at steady state and dynamic loading conditions. All outputs are measured with reference to the return remote sense (Returns) signal. The +5V, +3.3V, +12V, -12V and +5VSB outputs are measured at the power supply connectors references to Returns. The +5V and +3.3V are measured at its remote sense signal (+5VS, +3.3VS) located at the signal connector.
| Output Voltage | +5V | +3.3V | +12V | -12V | +5VSB |
|---|---|---|---|---|---|
| Load Reg. | ±5% | ±5% | ±5% | ±5% | ±5% |
| Cross Reg. | ±5% | ±5% | ±5% | ±5% | ±5% |
| Line Reg. | ±1% | ±1% | ±1% | ±1% | ±1% |
| Ripple & Noise | 50mV | 50mV | 120mV | 120mV | 50mV |
Ripple and Noise shall be measured using the following methods:
- Measurements made differentially to eliminate common-mode noise.
- Ground lead length of oscilloscope probe shall be 0.25 inch.
- Measurements made where the cable connectors attach to the load.
- Outputs bypassed at the point of measurement with a parallel combination of 10uF tantalum capacitor in parallel with 0.1uF ceramic capacitors.
- Oscilloscope bandwidth of 0 Hz to 20MHz.
- Measurements measured at locations where remote sense wires are connected.
- Regulation tolerance shall include temperature change, warm up drift and dynamic load.

Diagram: Turn On/Off Timing (illustrates AC Input, Vout, PWOK, +5VSB, PSON# signals over time)
2.4 Remote On/Off Control: PSON#
The PS_ON signal is required to remotely turn on/off the main output of the power supply. PS_ON is an active low signal that turns on the main output power rail. When this signal is not pulled low by the system or left open, the outputs (except the +5VSB) turn off. PS_ON is pulled to a standby voltage by a pull-up resistor internal to the power supply.
| Signal Type | Description |
|---|---|
| PSON# = Low | Power ON |
| PSON# = High | Power OFF |
2.5 Efficiency (80+ Gold)
2.6 +5VSB (Standby power)
The +5VSB output always provides output when AC power is applied and the power switch is turned on. The +5VSB line can provide up to 3.5A of current for PC board circuit operation.
3. Protection
Protection circuits inside the power supply shall cause only the power supply's main outputs to shutdown. If the power supply latches off due to a protection circuit tripping, either an AC cycle OFF for 15 sec or PSON #cycle HIGH for 1 sec must be able to restart the power supply.
3.1 Over power protection
The OPP function shall work at 110%~150% of rating of output power, then all outputs shut down in a latch off mode. The latch shall be cleared by toggling the PSON# signal or by cycling the AC power. The power supply shall not be damaged from repeated power cycling in this condition. If only one module works inside the power supply, the OPP is at 110%~160% of rating of power supply.
3.2 Over voltage protection
Each hot swap module has respective OVP circuit. Once any power supply module shuts down in a latch off mode while the output voltage exceeds the over voltage limit shown in Table 7, the other modules should deliver sufficient power to the device continually.
| Voltage | Minimum | Maximum | Shutdown Mode |
|---|---|---|---|
| +5V | +5.7V | +6.5V | Latch Off |
| +3.3V | +3.9V | +4.5V | Latch Off |
| +12V | +13.3V | +14.5V | Latch Off |
| +5VSB | +5.7V | +6.5V | Auto recovery |
3.3 Over current protection
The power supply should contain the OCP function on each hot swap module. The power supply should be shut down in a latch off mode while the respective output current exceeds the limit as shown in Table 8. When the latch has been cleared by toggling the PSON# signal or cycling the AC input power, the power supply module should not be damaged in this condition.
| Voltage | Minimum | Maximum | Shutdown Mode |
|---|---|---|---|
| +5V | 110% | 150% | Latch Off |
| +3.3V | 110% | 150% | Latch Off |
| +12V | 110% | 150% | Latch Off |
| +5VSB | 110% | 150% | Auto recovery |
3.4 Short circuit protection
The power supply shall shut down in a latch off mode when the output voltage is short circuit.

5.2 AC Input leakage current
Input leakage current from line to ground will be less than 3.5mA rms. Measurement will be made at 240 VAC and 60Hz.
6. Redundant power supply function
6.1 Redundancy
The redundant power supply is N+1=N, meaning that if one module fails, the system continues to operate. This applies to all models:
- (600W+600W=600W)
- (700W+700W=700W)
- (800W+800W=800W)
- (900W+900W=900W)
- (1000W+1000W=1000W)
Each module is redundant when any one module fails. To be redundant, each item must be in the hot swap power supply module.
6.2 Hot swap requirements
Hot Swapping a power supply is the process of inserting and extracting a power supply from an operating power system. During this process, the output voltage shall remain within specified limits. The hot swap test must be conducted when the system is operating under static, dynamic and zero loading conditions. The power supply can be hot swapped by the following methods:
Extraction
The power supply may be removed from the system while operating with PSON asserted, while in standby mode with PSON de-asserted or with no AC applied. No connector damage should occur during un-mating of the power supply.
Insertion
The power supply may be inserted into the system with PSON asserted, with PSON de-asserted or with no AC power present for that supply. No connector damage should occur due to the mating of the output and input connector. In general, a failed supply may be removed and replaced with a good power supply. Hot swap needs to work with operational as well as failed power supplies. The newly inserted power supply will turn on into standby or Power On mode once inserted.
6.3 Current Sharing
As this power supply has redundant function, the output current sharing should be within ±5% when at half and full load. The supplies must be able to load share in parallel and operate in a hot-swap/redundant configuration.

9. Power supply connector overuse definition
Image description: A close-up view of a multi-pin power supply connector, showing several rows of pins, some of which appear discolored or damaged, indicating potential overuse or heat stress.
A single PCIe 8pin cable and connector's maximum current rating is 12.5A, which is 150W (+12V x 12.5A). 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). Users should 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.
The 24pin motherboard connector's maximum current rating for its dual +12V metal pins are 5A each, which totals 120W (+12V x 5A x 2). Users should 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.
