Overview

The COMeap 24-pin to 6-pin ATX power adapter cable is a practical solution for using standard ATX power supplies with HP workstations and desktop PCs that feature proprietary 6-pin motherboard connectors. It supports a wide range of HP models including Z200/Z220/Z230/Z240 series, ProDesk 600 G1/G2, EliteDesk 800 G1/G2, and many Compaq business desktops. The cable measures 34cm (13.3 inches) and is rated for up to 1000W, making it suitable for high-end PSU upgrades.
This adapter converts a standard 24-pin ATX connector into the HP-specific 6-pin layout. It also includes a secondary small 6-pin P2 connector for certain motherboard variants. The design incorporates improvements to eliminate fan error beeps that often occur when using non-OEM power supplies. However, some models (notably HP EliteDesk G2 and ProDesk 600 G2 Micro Tower) may still trigger fan errors, so compatibility should be verified before purchase.

Connectivity & Compatibility

  • Connectors: 1x 24-pin ATX (PSU side) → 1x standard 6-pin + 1x small 6-pin P2 (motherboard side)

  • Supported HP models:

  • Z200 / Z220 / Z230 / Z240 (SFF, MT, TWR)

Product Info

Released around 2024, this adapter is available on online retailers for approximately ¥10,750. COMeap is a brand specializing in PC accessories, and this product occupies a niche mid-range position as a conversion solution for HP proprietary power connectors. The package includes the adapter cable and one piece of adhesive tape. Warranty details are not explicitly stated, but online retailers's standard return policy applies.
In the market, this adapter is one of the few reliable options for upgrading or replacing the power supply in older HP workstations and business desktops. It allows users to leverage modern ATX PSUs with higher efficiency and capacity, breathing new life into legacy systems.

Best Use Cases

  • Upgrading HP workstation (Z-series) power supplies: If your original PSU has failed or you need more power for a GPU upgrade, this adapter lets you use a standard ATX power supply. Ensure the case has enough physical space for the new PSU.
  • Customizing used HP desktops: For ProDesk or EliteDesk systems bought second-hand, swapping the PSU can enable better performance. Check the compatibility list carefully to avoid fan error issues.
  • Reusing spare ATX power supplies: If you have a quality ATX PSU lying around, this adapter makes it usable in compatible HP machines. Note that it is not intended for non-HP systems.
    This product is not recommended for users who need longer cables (34cm may be too short for large towers) or who want to use it with non-HP motherboards.
