Safety and Protection
WARNING: This unit unit has no user-serviceable parts inside. Opening the
casing presents a risk of electrocution and will void the product's warranty.
OVERSTEEL will not be responsible for any result of improper use, including
but not limited to, any use of the product outside of its intended purpose or
use inconsistent with the warranty terms available online.
Over-voltage protection (OVP)
Over-voltage protection for the 12V, 5V and 3.3V DC outputs is required to comply with the
ATX specification. OVP shuts down the PSU in the event that the DC outputs exceed a set level,
determined by the PSU manufacturer. The minimum voltage levels required for compliance are
13.4V for the +12V rail(s), 5.74V for the +5V rail and 3.76V for the 3.3V rail.
Under Voltage Protection (UVP)
Under-voltage protection for the 12V, 5V and 3.3V DC outputs. UVP shuts down the PSU
in the event that the DC outputs exceed a set level, determined by the PSU manufacturer.
Short-circuit protection (SCP)
A short-circuit is defined as any output impedance of less than 0.1 ohms. Amongst other things,
SCP ensures that the PSU shuts down should the 3.3V, 5V and 12V rails short to any other rail,
or to ground. It also ensures that no damage should occur to the unit, or your PC's components
in the event of a short.
Over Power Protection (OPP)
The over-power protection (OPP) kicks in when the power we pull from a PSU exceeds its
maximum rated capacity. Usually, the manufacturers give a little room for overpowering the PSU,
so the OPP threshold is set to 50 to 100W (in some cases even more) above the maximum rated
wattage of the PSU. In single +12V rail PSUs, where OCP is meaningless in most cases, OPP
takes over its role and shuts down the PSU in case the +12V rail is overloaded.
