Compact SFX power supply unit with matte black finish and fixed cable harness

SMUGDESK

SMUGDESK 500W SFX power adapter D500EPS-01 L500EPS-01 VFFKJ TPX56

SKU CH-R1RB-1MBR2

500W SFX power supply replaces Dell D500EPS-01 in Optiplex, Vostro, XPS and Precision T3660 towers with 80 Plus Platinum efficiency and OEM cable layout

  • Drop-in replacement for Dell Optiplex, Vostro, XPS and Precision T3660
  • 500W continuous output with 80 Plus Platinum efficiency and Active PFC
  • Pre-routed OEM wiring harness with dual 6+2Pin PCIe and SATA cables
  • Smart variable-speed fan with industrial-grade capacitors for quiet 24/7 operation
  • Full OVP, OCP, SCP, OTP protection with CE, FCC, RoHS certification

OEM Replacement for Dell Towers

This 500W SFX power supply is built to replace the original Dell units in Optiplex 3000 5000 7000 7020 Plus MT, Vostro 3690 3900 3901 3910 3991, XPS 8950 8960 and Precision T3660 systems. It matches the factory part numbers D500EPS-01 L500EPS-01 VFFKJ TPX56 for a direct drop-in fit without chassis modifications. The unit suits IT maintenance teams and owners restoring these specific desktops to working order.

Plug-and-Play Cable Harness

Installation uses the pre-routed OEM wiring harness with fixed mainboard connector, 4+4Pin CPU power, dual 6+2Pin PCIe and multiple SATA leads cut to stock lengths. No adapters or cable extensions are required, but builders adding non-standard GPU power configurations or extra drive bays beyond the factory layout will find the fixed harness restrictive. The SFX form factor aligns with existing mounting holes for a straightforward swap.

Sustained 500W Platinum Efficiency

The single +12V rail delivers continuous 500W output under 80 Plus Platinum efficiency across 100-240V auto-range input with Active PFC. Temperature-regulated fan and industrial-grade capacitors maintain stable voltages during 24/7 operation, while OVP OCP SCP OTP circuitry protects connected hardware during prolonged heavy loads. Systems demanding peak power beyond the rated 500W ceiling will require a higher-capacity unit.

Questions about this item

How can I confirm the 500W SFX power adapter is working correctly after installing it in my Optiplex 7000?

The system should power on immediately, the fan should spin quietly at idle, and the motherboard LEDs will show normal voltage readings with no error beeps.

What cables come pre-attached to the D500EPS-01 and do I need to buy any extra connectors for a Vostro 3910?

The unit includes a fixed mainboard connector, 4+4-pin CPU power, dual 6+2-pin PCIe and multiple SATA cables — no extra cables are required for the listed models.

Should I choose the L500EPS-01 or the VFFKJ version for a Precision T3660 tower?

Both part codes refer to the same 500W SFX unit; the supplier confirms full cross-compatibility with the Precision T3660, so either label will fit and function identically.
