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 figure1. 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, or operation temperature.
Ripple voltage test circuit
Overshoot
Any overshoot at turn on or turn off shall be less than 10% of the nominal voltage value, all outputs shall be within the regulation limit of section 2.0 before issuing the power good signal of section 5.0.
Efficiency
Power supply efficiency typically 87%/20% Loading, 90%/50% Loading, and 87%/100% Loading, at normal AC main voltage.
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.
PROTECTION
Over-power protection
The power supply will be shut down and latch off when the output power is over 110% ~ 160% of rated DC output.
Over current protection
The power supply shall have a 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 shut down and latch off.
| Voltage | Over Current Limit (Iout limit) |
| +12V | 55A minimum; 75A maximum |
| +5V | 17A minimum; 45A maximum |
| +3.3V | 22A minimum; 45A maximum |
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.
| Output | Minimum | Nominal | Maximum | Unit |
| +12 VDC | 13.4 | 15.0 | 16.5 | Volts |
| +5 VDC | 5.74 | 6.3 | 7.0 | Volts |
| +3.3 VDC | 3.76 | 4.2 | 5.1 | Volts |
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 the 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.
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.
TIMING
The signal timing drawing is a reference for signal timing for main power connector signals and rails.
- T2: Rise time (0.2ms~20ms)
- T3: Power good signal turn-on delay time (100ms~500ms)
- T4: Power good signal turn off delay time (1ms min)
- T5: Rise time (10ms max)
Output Transient Response
Table 13. summarizes the expected output transient step sizes for each output. The transient load slew rate is =1.0A/us.
| Max.step size | Max.step size | |
| Output | (% of rated output amps per Sec 3.2.3)(1) | (amps) |
| +12 VDC | 40% | Â |
| +5 VDC | 30% | Â |
| +3.3 VDC | 30% | Â |
| -12 VDC | Â | 0.1A |
| +5 VSB | Â | 0.5A |
For example, for a rated +5 VDC output of 18A, the transient step would be 30% x 18A=5.4A Output voltages should remain within remain within the regulation limits of Section 2.1, and the power supply should be stable when subjected to load transients per Table 13.
from any steady-state load, including any or all of the following conditions:
- Simultaneous load steps on the +12 VDC,+5 VDC, and +3.3 VDC outputs (all steps occurring in the same direction)
- The load-changing repetition rate of 50 Hz to 10 kHz
- AC input range per Section 1.0
Hold up time
When the power loses its input power, it shall maintain 12ms at 75% load in regulation limit at nominal input voltage. (AC:115V/60Hz or 230V/50Hz)

FAQs SilverStone Technology 600W SFX Form Factor PSU
Does SilverStone produce quality PSUs?
Excellent PSUs are made by SilverStone. For the past ten years, I’ve utilized SilverStone Tek PSUs. One was installed in an Alienware box starting around 2005, and I purchased a second one in 2011 since I thought a PSU that had lasted in a powerful gaming PC for around 6 years was plenty for me.
The SFX power supply’s size?
Typically measuring 125 x 63.5 x 100 mm, SFX PSUs are smaller than ATX or EPS PSUs and can fit in some mini-ITX or micro-ATX cases.
Is SFX superior to ATX?
The smaller size of SFX PSUs allows them to run cooler than bigger ATX PSUs, which reduces the need for huge fans that may be noisy and annoying while gaming or working on difficult jobs like video editing or streaming. SFX PSUs also have other advantages.
Is SFX PSU compatible with ATX?
No, as long as the wires are long enough to reach every component, you may use an SFX PSU in any case size. The V SFX Platinum, for instance, has a bracket that enables it to fit in an ATx case. The SFX PSU does, however, function well in smaller cases.
Do SFX power supplies cost more?
Despite the wattage, it’s still expensive: Power supplies with lower wattages are often less expensive and can be found for well under $100. Unfortunately, the fact that this is an SFX unit makes it more expensive than ATX 600W PSUs due to the unit’s specialized nature.
Which is bigger, SFX or ATX?
SFX is 125 x 100 x 63.5 mm (width, depth, and height), has a 60 mm fan, and is smaller than the typical ATX form factor, which measures 150 x 86 x 140 mm. An SFX unit can have an optional 80 or 40-mm fan replacement to change its height.
The ideal power supply for gaming?
Since Game Rant last took a look at it, the GIGABYTE GP-UD1000GM PG5 1000W PSU has undergone a significant price reduction, making it a considerably more budget-focused PSU than most of its immediate competitors.
Can it last ten years?
Aged capacitors and other components, power surges, heat, and other mechanical pressures are the main culprits. Having said that, premium manufacturers like Seasonic provide PSUs that can last ten years or more.
What exactly does SFX mean?
The term “SFX” can refer to any special effect, but it is most frequently used to refer to sound effects in movies and television. In cinema and video, sound effects and special effects are utilized to affect the audience’s emotions and responses.
FPS can PSU be increased?
No. Performance is not directly impacted by the PSU, but it may be impacted if yo le. ur system starts to throttle back when the peak load exceeds what the PSU can handle.
