More modern ATX power supplies can deliver almost all (typically 80–90%) of their total rated capacity in the form of +12V power. Power supplies label their total power output, and label how this is determined by the amperage limits for each of the voltages supplied. For the same example, only 37% of the units (fewer than a half) are expected to last 100,000hours without failing.[a] The formula for calculating predicted reliability, R(t), is R(t) = e Thermaltake TR2 50... 5. http://www.newegg.com/Power-Supplies/SubCategory/ID-58

Computer Power Supply Voltages Reply HELP for help.

This voltage is generated by shifting and transforming the pulses of the 5V rail on an additional choke, causing the voltage to rise delayed and rectified separately into a dedicated 3.3V Voltage drop on connectors forced the designers to place such buck converters next to the device. When the power factor correction (PFC) was required, those filter capacitors were replaced with higher-capacity ones, together with a coil installed in series to delay the inrush current. Cooler Master. 2008. Computer Power Supply Price

The benefit is they are generally cheaper than most modular PSUs of the same quality. The OCP on single-rail units kicks in only at much higher amperages, which could lead to a major melt-down if a serious overload occurs.
