ELFJMZP ATX 24-Pin to ATX 6-Pin + HP 2.54mm 6P-4P Power Adapter Cable for HP Z220/Z230, EliteDesk 800 G1 & ProDesk 600 G1
Product description
What this is and who it’s for
This is a dedicated ATX power adapter cable designed to bridge the gap between HP’s proprietary 6-pin motherboard connector and standard 24-pin ATX power supplies. It’s targeted at older HP workstation and business desktops such as HP Z220/Z230 18E4 workstations, EliteDesk 800 G1 (SFF/MT/TWR), and ProDesk 600 G1 models. If you’re upgrading a power supply in one of these systems and want to avoid replacing the original HP PSU, this cable offers a practical workaround.
How it’s built and what to expect
The cable uses 18AWG conductors for better current handling and reliability, with a robust PVC jacket designed to resist wear inside busy PC cases. It measures about 13 inches (33 cm), a length that typically fits neatly within most HP form factors without fussing with excess slack or blocking airflow. The product is advertised as 100% new with factory testing to minimise the chance of faulty connections.
The upside: where it makes sense
On the surface, this adapter solves a real compatibility problem: pairing older HP power supplies with motherboards that use a non-standard 6-pin connector. If your goal is to extend the life of an existing HP build rather than investing in a brand-new PSU, this can be a sensible option. The 320W maximum rating is a useful reminder to verify that the upgraded setup stays within safe power limits for the system you’re working with.
The limits: what to be mindful of
There are a few caveats that matter in practice. First, you must ensure the pin configuration of the old HP connector matches the adapter’s layout, a mismatch could risk improper operation or hardware damage. Second, the stated 320W ceiling means this isn’t suitable for high-power builds or systems that demand more from the PSU than typical office/workstation tasks. Finally, while the cable is designed to reduce installation snags, the upgrade work is best performed by a qualified technician to minimise the risk of wiring mistakes or short circuits.
Pros and cons at a glance
- Pros: enables power-supply upgrades without replacing HP units, 18AWG conductors for safer power transfer, custom length that suits HP form factors, factory-tested for reliability.
- Cons: limited to older HP systems with the specific 24-pin to 6-pin setup, power ceiling of 320W, requires careful pin verification and professional installation.
What it’s best for
If you’re maintaining or refurbishing legacy HP workstation or small-business desktops and want a pragmatic way to upgrade the PSU, this adapter can save time and money. It suits technicians carrying out routine maintenance on Z220/Z230, EliteDesk 800 G1, or ProDesk 600 G1 families where a newer HP PSU isn’t necessary or available.
When to look elsewhere
If your system has moved beyond HP’s older 24-pin/6-pin arrangement, or if you need more headroom for higher power consumption, a more modern PSU and motherboard upgrade would be more future-proof. Not every HP model is a fit for this cable, so if you’re unsure about compatibility, a professional assessment is wise.
Before you buy: check these points
- Confirm the exact HP motherboard connector configuration and compare it with the adapter’s pins.
- Verify your power requirements do not exceed 320W.
- Ensure the 13 inch length is adequate for the internal layout of your case (SFF/MT/TWR variations).
- Consider having a technician perform the installation to avoid wiring errors or short circuits.
Practical usage example
A technician upgrading an HP EliteDesk 800 G1 with an older PSU can use this cable to connect the 24-pin ATX from a compatible power supply to the HP proprietary 6-pin motherboard input. With careful alignment of pin slots and secure routing, the upgrade can be completed without removing the motherboard or replacing the original power rails, assuming the system’s power needs stay within the 320W limit.
FAQ (brief)
- Is this compatible with all HP desktops? It targets specific models listed in the product description, compatibility depends on the exact motherboard connector layout.
- Can I use this cable for gaming or high-demand workloads? Likely not ideal for power-hungry setups, given the 320W rating.
- Should I install it myself or hire a pro? Given the pin-matching and risk of short circuits, professional installation is recommended.
Final section: Should you buy it?
Should you buy it? Worth considering if you have an HP Z220/Z230, EliteDesk 800 G1, or ProDesk 600 G1 and you want to upgrade a legacy PSU without changing the original HP unit. It’s a practical, if niche, solution that can extend the lifespan of older hardware when power needs are modest and match the adapter’s rating. If your system demands more power or uses a different connector scheme, this may not be the best path forward.
