ENP-7660L is Enhance Electronics' second modular power supply, finally taking everything that was great about the ENP-7660B updating to support next gen PCI-E 5.0
Looking at the array of modular connectors its easy to get lost, but working from Left to Right they are as follows.

- 3pin header voltage sense lines for 24pin ATX connector
- Connector for CPU/GPU
- 14pin to 24pin ATX connector
- Connector for GPU/CPU
- 4pin Peripheral connector (3.3/5/12V/GND)
      *Only a single 12V-2x6 GPU cable maybe used at any one time.

Included is an extensive cable set as follows:
1x 24pin ATX loom 18cm
1x 24pin ATX loom  35cm
1x 8pin CPU power 40cm
1x 8pin + 4+4pin dual CPU power 40cm
1x 16pin 12V-2x6 GPU power 25cm 450W (compatible with older 12VHPWR GPU)
1x 6+2pin + 6+2pin dual PCI-E GPU power 25cm
1x 4pin to dual SATA 40+10cm
*Just a single ATX, CPU, GPU maybe used at any given time this more extensive loom set allows the power supply to be used in a wider range of cases and system configurations.

Remote On/Off:
Special feature, not currently shown, two 2mm pitch PS-ON feed through connectors.
Optional to use, they enable PS-ON to be daisy chained through for multiple PSU based applications. For example, 2 (or more) PSUs maybe used in one system with one dedicated to GPU alone or perhaps a GPU is used externally or other 12V power devices with its power up status being sychnonised with the main controling system via the PS-ON link cable. Or PSU(s) maybe remotely switched ON/OFF via a swtich
