KHACHIMO PE1430 Precision 490 690 SC1430 24P+20P 750W Power Supply

Dell Precision 490 690 SC1430 Compatibility

This 750W ATX power supply is designed for Dell Precision 490, 690 and SC1430 workstations. It delivers the factory pin-out and connectors those chassis expect, making it a direct replacement for the original unit. Builders upgrading or repairing these specific models will find the correct 24-pin and 20-pin main cables already fitted.

Installation Notes

The unit fits the standard ATX mounting pattern used in the listed Precision towers, so no adapter brackets are required. Cable routing follows the original layout, but the stiff 24-pin and 20-pin leads can be tight behind the motherboard tray; allow extra slack when dressing them. Verify the 0MK463 or 0U9692 part label matches your existing supply before fitting.

Sustained Load Behaviour

With 80 PLUS Gold certification and resonant LLC topology plus DC-to-DC conversion, efficiency stays high across a wide load range, keeping internal temperatures lower during long workstation tasks. The Zero RPM fan mode remains off at low and medium loads, so acoustic output stays minimal until sustained demand spins the fan up. Modern Standby support allows rapid wake from sleep without voltage droop.
