This connection allows remote sensing of the voltage drop in the power-supply wiring. ATX is the most common motherboard design.[1] Other standards for smaller boards (including microATX, FlexATX, mini-ITX and extended ATX) usually keep the basic rear layout but reduce the size of the a. Typically, a power supply will guarantee at least 17A at 12V by having a current limit of 18.5 A ± 8%.

Rather than add more current limit circuits, many manufacturers have chosen to ignore the requirement and increase the current limits above 20A per rail, or provide "single-rail" power supplies that omit Video cards 1 2 3 4 5 6 X None ATI FireGL V3200ATI FireGL V5200ATI FireGL V7100ATI FireGL V7300ATI FireGL V7350ATI FireGL V7700ATI FireGL V8600ATI FireGL X1-256ATI FireGL X3-256ATI FirePro V3700ATI Retrieved 18 November 2014. ^ "Power Supply Design Guide for Desktop Platform Form Factors, Revision 1.31" (PDF).

Results 1 to 10 of 10 Thread: How do I check the size of my power supply? Watts-up-pro Es If you do open the case, do turn off the power first, you may also want to get some of the dust out too carefully with a vacuum or a can Some power supplies come with sleeved cables, which besides being more aesthetically pleasing, also make wiring easier and have a less detrimental effect on airflow.

The new connector also provides a 3.3volt source, removing the need for motherboards to derive this voltage from the 5V rail.
