    Flying Sausages got a reaction from Dean0919 in do you favor a computer with fan noise?   
    Silence as possible. I don't want my computer case fans sound like a jet engine is about to take off.

    Flying Sausages got a reaction from weeblord in [psucultists] PSU Tier List   
    @LukeSavenije and @jonnyGURU and other people contributed to build this list
     
    Thank you very much for your recommended power supply list and hard work to build this list. This list save me and other people a lot of time from buying shit power supply that can potentially destroy the whole computer. In addition, this list save a lot of people time from spending more than 2 hours from researching the power supply they are about to buy and turn out it is a no no power supply.

    Flying Sausages reacted to LukeSavenije in PSU Protections - What do they help against and how do they work?   
    Introduction
    There are many things you should look for on a PSU, and subjectively protections are one of the most important, if not the most important thing to look for. They will shut down the PSU down because of too much power, too much or too little voltage, short circuits or high temperatures. Here will be a breakdown of every protection. What they do, how they technically work and how important it is.
     
    Some terms used
    Protection IC= an integrated Circuit that monitors the PSU, integrating most, and in some cases all protections.
    ATX Standard= A standard set by Intel with all the requirements or recommendations for PSUs in regard of protections, voltage regulation, ripple and so on. 
    Shunt resistor= a device which creates a low-resistance path for electric current, to allow it to pass around another point in the circuit. This way it can measure current
    Thermistor=A type of resistor whose resistance is dependent on temperature.
     
    OPP (Over Power Protection)
    Over Power Protection or OPP is a protection that will shut down the PSU when too much power is pulled, generally this is between 110 and 140% of the advertised wattage. This is a protection that works as a limit, shutting down when a certain point is reached, but doesn't actively monitors the amount of current.
     
    It's generally integrated into the PWM controller and is a crucial protection. It's required in ATX except if OCP is also there.
     
    OCP (Over Current Protection)
    Over Current Protection or OCP has the same purpose, but a different concept as OPP. OCP will generally be faster than OPP, since it uses shunt resistors to check the amount of current, and will shut down if a certain point is reached. OCP on 12v is generally only found on PSUs with multiple rails, since OPP can handle a single rail just fine.
     
    It's generally integrated into the protection IC combined with shunt resistors and is a recommended, but not required protection by ATX.
     
    OTP (Over Temperature Protection)
    Over Temperature Protection or OTP is a protection that protects the PSU against overheating with for example a fan failure. it's generally a thermistor combined with a protection IC that supports this, but there have also been cases where it was integrated into the fan controller. Most reviewers stop measuring after 200c, but it depends on the place the thermistor is integrated what recommended limits are.
     
    It's recommended until ATX 2.52, but since has been required.
     
    UVP (Under Voltage Protection)
    Under Voltage Protection or UVP is meant to shut down if voltage goes down too far. not only because a lot of components need a stable voltage, so you can have less correction on the VRM side, it's also there because OCP and OPP measure by how much current is going through, but not the voltage. so if the voltage drops down, the current can go higher, which can result in burnt cables or connectors.
     
    It's generally integrated into the protection IC, and recommended in the ATX standard, but required for a modern PSU in my eyes.
     
    OVP (Over Voltage Protection)
    Over voltage Protection or OVP works to a similar way as UVP, but the other way around. It checks the voltage on a rai that it isn't getting too high, so it can keep a safe height, and will shut down if it gets too high.
     
    It's generally integrated integrated into the protection IC and required by ATX standards.
     
    Voltages for OVP according to ATX spec
    Output        Minimum (V)    Nominal (V)    Maximum (V) +12 VDC  13.4 15 15.6 +5 VDC 5.74 6.3 7 +3.3 VDC 3.76 4.2 4.3 5VSB 5.74 6.3 7  
    SCP (Short Circuit Protection)
    Short Circuit Protection or SCP measures the resistance on each rail, and will shut down when resistance is lower than 0.1 Ohms. Generally this goes combined with OPP, OCP, OVP and UVP.
     
    It's generally integrated into the protection IC, and is required on ATX spec, with separate circuits per rail.
     
    PWR_OK Signal
    The Power Good or PWR_OK signal is a delay signal to show if the PSU has enough energy stored for at least 17 ms under maximum load. This delay must be under 500ms, but is preferred below 250ms according to the ATX specification, but must be higher than 100ms.
     
    Verdict 
    OPP is required, for when too much power is pulled.
    OCP is recommended, and is meant for the same thing.
    OTP is required since the most recent ATX specification when too high temperatures are reached.
    UVP is recommended by ATX, required by me for when voltage drops too low
    OVP is required by ATX for when voltage goes too far up.
    SCP is required for when resistance gets too little.
    PWR_OK is required to signal the PSU can still function right until the next one.
