Who it fits

Key specs explained

Dual 24pin female + single 24pin male connectors

This connector layout allows you to link two separate power supplies to one motherboard. The single male plug enters the motherboard, while the two female ports accept inputs from different units. This design is essential for cryptocurrency mining rigs that require redundant power or increased current delivery beyond a single unit's capacity.

Total Cable Length of 500+150mm

The cable measures 500mm plus an additional 150mm segment. This extra length provides flexibility when routing wires in cases with multiple power supply bays. You can position units further apart without straining connections. This is useful for building custom mining frames where spacing between hardware components varies significantly from standard desktop configurations.

Female 24pin x 2, Male 24pin (20+4) x 1

The adapter features two female 24-pin sockets and one male 24-pin connector with a 20+4 pin configuration. This ensures compatibility with modern motherboards that use the standard 24-pin ATX power interface. The split design supports dual power input, which is critical for stability in high-load mining environments where power redundancy prevents system crashes.

Ideal for using two Power Supplies for Crypto coin Mining

This product is specifically engineered for cryptocurrency mining operations. It enables the use of two power supplies to meet the high power demands of mining hardware. This setup improves reliability by providing backup power. If you are building a mining rig, this adapter ensures your motherboard receives stable power from multiple sources, reducing downtime during intense computational tasks.

Design and Build Details

According to the listing, the SilverStone SST-PP10 is a specialized adapter rather than a standalone power supply unit. Its primary function is to enable the connection of two power supply units to a single motherboard. This configuration is particularly useful for cryptocurrency mining setups where additional power delivery is required. The device features dual 24-pin female connectors and a single 24-pin male connector. This layout allows you to plug in two separate power sources into one main motherboard input, ensuring stable power distribution for high-demand components.

The physical dimensions are listed as 2.5 inches in width, 0.5 inches in height, and 25.6 inches in length. The cable assembly includes a total length of over 500mm plus an additional 150mm section. This extended length provides flexibility in cable management within large cases. The compact profile of the adapter itself means it does not take up significant space near the motherboard socket. You can route the cables more easily in tight chassis environments without obstructing airflow or other components.

The construction focuses on functionality for dual PSU setups. The connectors are designed to accept inputs from different units, allowing you to split the power load. This is not a standard power supply but an adapter that facilitates a specific hardware configuration. The build prioritizes the ability to handle the combined current from two sources. You should ensure your motherboard supports this dual input method before relying on this adapter for your mining or high-performance rig.

Setup and everyday use

Setting up this adapter involves managing cable length and connector placement. The total cable length is listed as 500+150mm. You need to account for this space when arranging two power supplies. The dual 24-pin female connectors accept inputs from separate units. A single 24-pin male plug connects to the motherboard. This layout allows you to distribute power across two sources. You must ensure your motherboard supports dual PSU input. Not all boards have this feature. The adapter does not regulate voltage. It simply bridges the connection. Daily use relies on stable connections. The female ports must remain secure. Loose connections can cause system instability. The design is intended for mining rigs. These setups often run for long periods. The cable length helps with airflow management. You can place power supplies further apart. This reduces heat buildup in the case. The 2.5-inch width and 0.5-inch height are compact. They fit into standard rack spaces. The 25.6-inch length provides reach. You do not need to move the motherboard. The adapter handles the electrical link. It does not add features like monitoring. You rely on your existing software for status. The product is a passive component. It does not require drivers. It works with any compatible motherboard. You check the manual for pinout details. The 20+4 pin male connector ensures compatibility. It fits both 20-pin and 24-pin slots. This flexibility simplifies installation. You avoid cutting wires. The setup is straightforward if you have the right hardware. The cable manages the power distribution. You focus on the rest of the system.

Before You Buy This Adapter

You are not buying a power supply unit. You are buying a specialized cable. The SilverStone SST-PP10 adapter lets you connect two separate power supplies to one motherboard. This setup is common in cryptocurrency mining rigs. You must ensure your motherboard supports dual PSU input. Most standard consumer boards do not. You will need two compatible power supplies. Check their connectors carefully. The adapter has two female 24-pin ports and one male 24-pin connector. The total cable length is 500 plus 150 millimeters. Manage this space in your case. This item fits alongside standard units for specific builds. It does not replace them. It extends their utility for niche tasks. Keep cables tidy. Dust can accumulate in the connectors. Clean them occasionally. This adapter is a tool for specific hardware configurations. It is not for general home PCs. Verify your use case matches the design. This ensures you get the intended performance without unnecessary complexity in your build.

Check before you buy

• Verify your motherboard supports dual PSU input.
• Confirm your power supplies have 24-pin connectors.
• Check if you have enough case space.
• Ensure you need crypto mining capabilities.
