DELL Optiplex Power Adapter Cable ATX 24P to 8P 30cm All Copper Tinned Wire for Optiplex 3020 7020 9020 T1700 Motherboards Supporting H61 H81 Q77 Q87 B75 A75 Q75 Q65 Models with 1000W High Power Capability
ATX 24-Pin to DELL 8-Pin Motherboard Power Adapter Cable 30cm for Optiplex Workstations

This 30cm power adapter cable provides a direct solution for powering DELL Optiplex and Precision workstation motherboards from standard ATX power supply units. Many DELL proprietary systems, including the Optiplex 3020, 7020, 9020 and T1700 models, utilise an 8-pin motherboard power connector rather than the more common 24-pin ATX connector. This cable bridges that gap, converting the 24-pin output from a conventional ATX power supply to the 8-pin input required by these DELL motherboards. It enables system builders, upgraders, and repair technicians to use readily available ATX power supplies instead of seeking out DELL-specific units, offering greater flexibility and component choice for workstation builds and repairs.
Features and Construction

This adapter cable is designed specifically for the electrical interface between ATX power supplies and DELL workstation motherboards. Its construction focuses on reliable power delivery and physical durability to meet the demands of constant workstation operation.
Material and Build
The cable is manufactured using all-copper tinned wire, which offers excellent electrical conductivity while providing some protection against oxidation and corrosion over time. The wire gauge is 18AWG, with a copper core configuration of 0.18x34 strands. This specification ensures the cable can handle the current required by high-performance workstation components, with explicit support for power supplies rated up to 1000W. The tinned copper construction maintains signal integrity and reduces resistance compared to cheaper aluminium or copper-clad aluminium alternatives.
Size and Practical Fit
With a length of 30cm, this cable provides sufficient reach for routing within typical mid-tower and small form factor cases while maintaining tidy cable management. The 42g weight indicates substantial build quality without being excessively heavy. This length is particularly useful in DELL's often compact workstation chassis designs, allowing the cable to be routed cleanly from the power supply bay to the motherboard connection point without excessive slack or tight stretches that could strain connectors.
Uses and Placement

This cable serves a specific but crucial role in both professional IT environments and enthusiast workshops. Its primary function is enabling compatibility between standard power infrastructure and DELL's proprietary motherboard designs.
Event or Professional Use
In professional IT departments, repair centres, and system integration businesses, this cable allows technicians to standardise on ATX power supplies across multiple client systems. Rather than maintaining inventory of DELL-specific power supplies for various Optiplex and Precision models, technicians can use this adapter with universal ATX units. This simplifies logistics, reduces spare part requirements, and speeds up repair turnarounds. The cable's 1000W support capability means it can handle even high-end workstation configurations with multiple graphics cards or extensive storage arrays.
Everyday Home Use
For home users upgrading older DELL workstations or building custom systems using DELL motherboard platforms, this cable provides access to the wider ATX power supply market. Enthusiasts can select from hundreds of ATX power supplies based on efficiency ratings, modular cabling, noise levels, or brand preference, rather than being limited to DELL's proprietary offerings. The cable enables cost-effective upgrades when the original DELL power supply fails, as replacement ATX units are often more readily available and competitively priced than genuine DELL components.
Benefits and Buying Value

The value of this adapter cable extends beyond simple connectivity, offering practical advantages in system flexibility, maintenance, and long-term usability.
Reuse and Low Maintenance
By enabling standard ATX power supply usage, this cable significantly extends the service life of DELL workstation motherboards. When the original DELL power supply fails, users aren't forced to replace the entire system or source expensive proprietary replacements. Instead, they can install any standard ATX power supply and continue using their workstation. This represents substantial cost savings in professional environments where multiple workstations share common failure points. The all-copper construction contributes to long-term reliability, with tinned wires resisting corrosion that can degrade performance over years of use.
Why Choose This Product
This cable addresses a specific compatibility gap with precise engineering. The 18AWG all-copper tinned wire construction ensures it can safely deliver the power required by workstation-class components, unlike generic adapters that might use inferior materials. The explicit support for DELL H61, H81, Q77, Q87, B75, A75, Q75, and Q65 chipset motherboards, along with Optiplex 3020, 7020, 9020, and T1700 models, provides clear compatibility guidance. The 1000W power rating offers headroom for substantial upgrades, while the 30cm length suits both compact DELL cases and standard ATX chassis. For anyone integrating DELL workstation motherboards into custom builds or maintaining existing DELL systems with alternative power supplies, this cable provides a reliable, specification-appropriate solution.
