24 Pin to 8 Pin ATX Power Adapter Cable for Dell OptiPlex 3020 7020 9020 Precision T1700 12Inch (30cm) 18AWG for Dell Proprietary PSU with Standard ATX Power Supply H61/H81/Q77/Q87 Motherboards

1. CONVERT STANDARD ATX PSU TO DELL 8-PIN MOTHERBOARD Replace your underpowered Dell OEM power supply (typically 290W) with any standard ATX PSU up to 1000W. This adapter connects the 24-pin output of your standard power supply to Dell motherboards that use a proprietary 8-pin power connector found in OptiPlex 3020/7020/9020 and Precision T1700 models.
2. CRITICAL COMPATIBILITY VERIFY YOUR DELL MODEL BEFORE ORDERING Compatible with: Dell OptiPlex 3020, 7020, 9020 (Mini Tower), Precision T1700, and motherboards with H61, H81, Q77, Q87, B75, A75, Q75, Q65 chipsets. NOT compatible with: Dell Inspiron 3653/3650/3655/3250/3252/3268/3660/3667/3668/3670, OptiPlex 3040/5040/7040 (different 8-pin pinout), any 6-pin Dell motherboards, or any non-Dell systems.
3. IMPORTANT: Additional 4-Pin CPU Power Required Most Dell motherboards compatible with this adapter (including OptiPlex 3020/7020/9020) require a separate 4-pin CPU power connection in addition to the main 8-pin motherboard power. This adapter only converts the main 24-pin power you must also connect a CPU 4-pin or 4+4 pin cable from your standard ATX power supply directly to the 4-pin CPU power header on your Dell motherboard.
4. BUILT-IN 12VSB BOOSTER MEETS DELL REQUIREMENTS Dell proprietary motherboards require +12V standby power instead of the standard +5VSB found on ATX power supplies. This adapter includes an integrated 12VSB booster circuit that converts +5VSB to the required +12VSB, ensuring proper standby power, wake-on functionality, and reliable system operation.
5. PREMIUM 18AWG CONSTRUCTION SAFE & RELIABLE Built with UL1007 18AWG tin-coated copper wire (0.18x34 copper core) for stable power delivery and minimal voltage drop. Rated for up to 1000W, making it suitable for high-performance upgrades including gaming GPUs. Factory-tested for reliability under load.
6. OPTIMAL CABLE LENGTH 12 INCHES (30CM) Total length of 12 inches (30cm) including connectors provides ample reach for routing inside mini tower cases while maintaining clean cable management. Includes a reusable cable tie for tidy organization.
7. IMPORTANT OPERATION NOTE When using this adapter with Dell motherboards, the power supply will remain powered on (fan may continue spinning) after computer shutdown. This is normal behavior due to Dell's proprietary power management design. Unplug the power cable or use a PSU with a physical power switch to fully power off.

Dell OptiPlex 3020, 7020, 9020, and Precision T1700 desktop computers use a proprietary 8-pin power connector on their motherboards, making standard ATX power supplies incompatible without an adapter. This 24 Pin to 8 Pin conversion cable solves that problem, allowing you to replace your underpowered Dell OEM PSU (290W) with any standard ATX power supply up to 1000W.

Built-in 12VSB Booster Circuit

Dell proprietary motherboards require +12V standby power instead of the standard +5VSB found on ATX power supplies. This adapter includes an integrated 12VSB booster circuit that converts +5VSB to the required +12VSB, ensuring proper standby power, wake-on functionality, and reliable system operation.

This cable is designed for Dell motherboards with a proprietary 8-pin power connector. It works with:

1. OptiPlex 3020 Mini Tower (MT)
2. OptiPlex 7020 Mini Tower (MT)
3. OptiPlex 9020 Mini Tower (MT)
4. Precision T1700
5. Motherboards with H61, H81, Q77, Q87, B75, A75, Q75, Q65 chipsets

DOES NOT WORK WITH:

1. Dell Inspiron 3653, 3650, 3655, 3250, 3252, 3268, 3660, 3667, 3668, 3670
2. OptiPlex 3040, 5040, 7040 (these use a different 8-pin pinout)
3. Any Dell motherboard with a 6-pin power connector
4. Dell Precision workstations (other than T1700)
5. Any non-Dell systems

Most Dell motherboards compatible with this adapter (including OptiPlex 3020/7020/9020) require a separate 4-pin CPU power connection in addition to the main 8-pin motherboard power.

This adapter only converts the main 24-pin power you must also connect a CPU 4-pin or 4+4 pin cable from your standard ATX power supply directly to the 4-pin CPU power header on your Dell motherboard.

If your power supply does not have a CPU 4-pin cable (or only has an 8-pin CPU cable), you may need to purchase a CPU 8-pin to CPU 4-pin adapter cable separately.
