Vszerda D500EPS-01 TPX56 500W power adapter
500W replacement power supply for Dell OptiPlex and Vostro desktops with 8+4+4 pin and dual 8-pin connectors
- Delivers 500 W to power demanding OptiPlex and Vostro towers
- Wide 100-240 V input works on global mains without a switch
- Dual (8+4+4) pin plus twin 8-pin connectors fit listed Dell motherboards
- Replaces L500EPS-01, D500EPS-01 and TPX56 part numbers directly
- Built new for OptiPlex 3000MT, 5000MT, 7000MT, Vostro 3710, 3910, T3660, XPS 8950
Target desktops
This 500 W power adapter replaces Dell part numbers L500EPS-01 and D500EPS-01 in Optiplex 3000MT, 5000MT, 7000MT, Vostro 3690, 3710, 3910, T3660 and XPS 8950 tower systems. It accepts 100-240 V input at 7.0 A across 50-60 Hz and delivers up to 500 W DC output for compatible workstations. It is not compatible with Optiplex 7010 or 7020 models.
Sustained delivery
The unit is rated for a continuous 500 W maximum DC output rather than a short-term peak, supporting steady loads from multi-core CPUs and discrete graphics during extended work sessions. Input range of 100-240 V at 7.0 A allows stable operation on global mains without voltage switching.
Connector layout
A fixed cable set provides an (8+4+4) pin block plus two separate 8-pin connectors, matching the motherboard and GPU power headers of the listed Optiplex, Vostro and XPS towers. Builders needing different pin counts or form-factor units such as SFF or micro-ATX chassis cannot use this adapter.

Questions about this item
How much heat and fan noise should I expect from the 500 W unit when it runs continuously?
The adapter draws up to 7.0 A at 100-240 V and delivers a maximum of 500 W, so sustained loads will produce heat proportional to the power drawn; fan speed ramps with internal temperature.
Which Dell chassis and motherboard connectors must my system already have for this supply to fit?
It requires the proprietary (8+4+4) pin main connector plus two 8-pin auxiliary connectors found on Optiplex 3000MT, 5000MT, 7000MT, Vostro 3710, 3910, T3660 and XPS 8950 motherboards.
Will this 500 W replacement work in an older Optiplex 7010 or 7020 tower I still use?
No — the supplier explicitly lists the 7010 and 7020 as incompatible, so the connector pinout or form factor does not match those models.
