Virtasovitin ShiverPeaks 24-pin 20-pin ATX-sovitin (S-Conn Handels GmbH AK ATX 24S20B)

The ShiverPeaks power adapter 24-pin to 20-pin ATX adapter converts a standard 24‑pin ATX power supply connector to a 20‑pin motherboard input. It is designed to maintain correct pin alignment and deliver the basic power rails required by legacy 20‑pin motherboards. The adapter is a passive, plug-and-play solution that enables compatibility between modern PSUs and older systems without modifying cables or connectors.

Advantages

This adapter preserves the standard ATX pinout for essential voltage lines, allowing safe connection of a 24‑pin power supply to a 20‑pin motherboard. Because it is passive and compact, installation requires no tools or electrical modifications. The adapter supports straightforward re-use of existing power supplies for testing, retrofitting, or temporary operation of legacy hardware while minimizing risk of misalignment during connection.

Suitable for

• Retrofitting older desktop systems that require a 20‑pin ATX connector
• Testing or benching power supplies with 20‑pin motherboards
• Temporary connections when replacing a power supply or migrating components

Key specifications

• Connector type: 24‑pin male to 20‑pin female ATX adapter
• Compatibility: standard ATX power supplies and 20‑pin motherboards
• Function: passive pin mapping for primary power rails (3.3V, 5V, 12V, ground)
• Form factor: compact inline adapter, no mounting required
• Installation: plug-and-play, no soldering or wiring needed

How to use

Align the adapter so the 24‑pin side fits onto the power supply cable or PSU header, and press the 20‑pin side firmly onto the motherboard connector. Ensure the latch engages to secure the connection and confirm that the power supply is switched off before connecting. After installing the adapter, power on the system and verify stable operation; if the motherboard does not power up, switch off and recheck the alignment and seating of the connectors.

Recommendations

Use this adapter only for systems that require the original 20‑pin ATX power layout and for temporary or test connections. Do not use it to bypass required additional power connectors (such as dedicated CPU or GPU power) that the motherboard or components may need. Inspect connectors for damage before use and avoid forcing mismatched plugs.
