Form factor

SFX is merely a form factor for a power supply casing and the power specifications are almost identical. Thus, an SFX power supply is mostly interchangeable with the ATX power supply. The only difference is that the SFX specifications do not require the -5V rail. Since -5V is required only by some ISA bus expansion cards, this is not an issue with modern hardware and decreases productions costs. As a result, ATX pin 20, which carried -5V, is absent in current power supplies; it was optional in ATX and ATX12V ver. 1.2, and deleted as of ver. 1.3.
SFX has dimensions of 100 x 125 x 63.5 (width x depth x height in mm) with 60 mm fan. Optional 80 or 40 mm fan replacement increases or decreases the height of the unit.
Some manufacturers and retailers incorrectly market SFX power supplies as µATX or MicroATX power supplies.

ATX version

Motherboards can come with either a 4 pin 12 volt connector or an 8 pin 12 volt connector. Many power supplies come with a 4+4 pin 12 volt cable which is compatible with both 4 and 8 pin motherboards. A 4+4 power cable has two separate 4 pin pieces. If you plug the two pieces of a 4+4 power cable together then you have a 8 pin power cable which can be plugged into an 8 pin 12 volt connector. If you leave the two pieces separate then you can plug one of the 4 pin pieces into a 4 pin 12 volt connector and leave the other 4 pin piece unplugged.

Power protection features

The OCP is one of the power supply's protective functions. It stands for Over Current Protection. If a voltage rail draws more current from a power supply than the power supply specification permits, then the OCP intervenes and switches off the power supply.

Over Voltage Protection protects the PC against overly high voltages. To prevent damages to the PC, the power supply turns off when an over voltage is present.

"Under Voltage Protection", or UVP for short, is a protective mechanism for output direct current. The power supply automatically switches off if the voltage converted by the power supply falls below a defined threshold. This protects the power supply and hardware components against damage.

SCP stands for "Short Circuit Protection" and represents an important protective function for power supplies. If a fault leads to a short circuit in the computer, the SCP function switches off the power supply to prevent additional defects to the hardware.

This important protective circuit stands for Over Temperature Protection. Heat is created within the power supply during control actions. It the interior of the power supply becomes overheated, the OTP protects the electronics against damages.

Similar to the OCP, the OPP is one of the protective circuits built into the power supply. OPP stands for Over Power Protection. If a power supply is operated at an excessive power level, the OPP protects the power supply against a technical breakdown.

Product type

The power supply unit is the main source of energy for the PC and ensures that all the elements installed in it are supplied with power. A distinction is made between the energy efficiency and the wattage of the power supply units. Also the form factor (e.g. ATX) and the modular cable management are important criteria which have to be considered when purchasing. When purchasing a power supply, you should pay attention to the power consumption of the various components, so that the power supply is then also able to supply all parts installed in the PC with sufficient power. It is also best to make sure you have enough connections for your graphics card (8-pin and 6-pin) and your processor (4-pin, 8-pin).
