5.1. Important Considerations for Cable Connections
Some users have reported variations in SATA connector spacing compared to original Dell power supplies. If you are connecting multiple hard drives side-by-side, you may find the spacing between the SATA power connectors on this unit to be shorter (approximately 1.5 inches) than on some original Dell PSUs (which might be around 5.5 inches). This could potentially make it challenging to power two closely mounted drives without an extension cable or modification. Additionally, ensure the SATA connectors are oriented correctly; some users have noted that the slot orientation might differ from original units, requiring careful alignment or a slight twist of the cable.
6. אַפּערייטינג ינסטרוקטיאָנס
