The AK680 uses sleeved cables which we find desirable. A 3rd strand has one Molex and one SATA connector, likely intended for the DVD drive. The SATA strand has 3x SATA power connectors. The Molex peripheral strand has 3x connectors with a single Berg connector on the end for a floppy drive.
The AK680 is an older design that uses separate circuits to each of the voltages. Ball bearing fans are more costly but they also are less noisy and have a longer service life. The AK680 uses a 120 mm ball bearing fan to keep the assembly cool. The AK680 uses a separate 4-pin and 8-pin connector separated by 8 inches of cable. The 4-pin ATX12V and 8-pin EPS12V connectors are standard for most motherboards. Video cards only use 8-pin if a pair of 6-pin connectors provide inadequate power. Better would have been to provide a pair of 6-pin PCI Express cables to support entry level gaming video cards. The PCI Express cable is a 6/8-pin capable of supporting a single display adapter. It features the standard 2×12 motherboard connector with a single strand of Molex and a single strand of SATA connectors. The AK680 is a standard ATX 2.3 class power supply. We would have liked a single 12V rail so that the load would be better balanced. The overall quality of the components is very basic. Typically one rail is used for the motherboard and the other supplies the PCI Express supplemental power. The AK680 uses a pair of 12V circuits to reduce costs. The paint is the best feature of the AK680 which does give it a modern look when installed in an older machine. The large 120mm fan on the bottom allows for a far greater air flow which is needed when the PSU is loaded. The AK680 has a gloss black finish with a screen panel on the back to allow the best airflow. The AK680 is the standard 140 mm deep which is allows for lots of room for DVD drives and the cable assembly. The AK680 is the standard ATX 86 mm by 150 mm at the back panel to fit the standard ATX screw positions. The old PSU had a single 12 V 20 A circuit which limited the use of advanced gaming grade video cards somewhat. The A-Power AK 680 power supply is a basic low cost generic ATX 2.1 model that we procured in for use with the desktop gaming machine. This was also done with the DynaPower brand of PSU which is also falsely labelled. This was then sold at far above its actual capacity which is false pretences. The A-Power AK680 is a counterfeit PSU made using a Leadman 8867 350W power supply board.
