Higher-quality power supplies can be over 80% efficient; as a result, energy-efficient PSUs waste less energy in heat and require less airflow to cool, resulting in quieter operation. The standard also specifies two additional four-pin 12V connectors for more power-hungry boards (one required on 700–800W PSUs, both required on 850W+ PSUs).

Power supplies designed for that generations of computers control the 5V output rail precisely and supply the 12V rail in a specified voltage window depending on the load ratio of both Because the physical shape (form factor) of the power supply relates to the case, some of this information also relates to the type of chassis or case you have. http://www.hardwaresecrets.com/everything-you-need-to-know-about-power-supplies/3/
This kind of power cable is fully compatible with both 20 and 24 pin motherboards. The few who do pay any mind seem concerned only with how many watts of power it is rated to put out (even though no practical way exists to verify those Answer this question Flag as...
Power Factor Correction (PFC)11. As with plugging a 24 pin cable into a 20 pin motherboard connector, you can plug an 8 pin cable into a 4 pin connector and leave 4 pins hanging over Assuming you have those, you need a good power supply. Motherboard Power Supply Connectors Active PFC is more complex and can achieve higher PF, up to 99%.
Because of this change, it is important to consider the +12V supply capacity, rather than the overall power capacity, when using an older ATX power supply with a more recent computer. Connect Power Button To Motherboard A power supply rail or voltage rail refers to a single voltage provided by a power supply unit (PSU). There are adapters which convert 20 pin cables into 24 pin cables but they don't solve the problem and can cause problems of their own. http://www.playtool.com/pages/psucompat/compat.html A second connector that goes to the motherboard (in addition to the main 24-pin connector) to supply dedicated power for the processor.

Power Supply To Motherboard Diagram Some power supplies have no-overload protection. if you are interested in building your own computer check out the other videos on my YouTube channel. The power rating is so high because the other voltage rails offer more amperage and more wattage.
silentpcreview.com. Read More Here For certain graphics cards, the PSU's 12V rating is crucial. Power Supply Compatibility With Motherboard Development PCB of a power supply from an IBM XT clone A typical XT PSU power switch, which is an integral part of the PSU Original IBM PC, XT and AT How To Install Power Supply To Motherboard It needs to provide enough power to run all of the components you have installed.
Thus, GPU manufacturers, to ensure 200–250W of 12V power (peak load, CPU+GPU), recommended power supplies of 500–600W or higher. navigate here Low-quality power supply manufacturers sometimes take advantage of this overspecification by assigning unrealistically high power supply ratings, knowing that very few customers fully understand power supply ratings. +3.3V and +5V rails There may be tie straps in the case, which may need to be cut.
