Flex PSU stands for "flexible power supply unit," which is a compact power supply designed for small form factor computers like mini PCs, POS systems, or slim desktop cases. These units are built to fit tight spaces where standard ATX power supplies wouldn't work. If you're building or upgrading a small computer, a flex PSU can help you save space without sacrificing power. Just make sure to check your case compatibility and power needs before choosing one.

To check if a flex PSU will fit your case:

• Measure the PSU compartment in your case and compare it with the flex PSU's dimensions (usually listed in the product details).
• Look for mounting points—flex PSUs use specific screw placements, so your case should support them.
• Check your case's documentation or search for "1U" or "flex ATX" compatibility.

If you're unsure, you can bring your case measurements to your local Walmart store or reach out to customer support for help.

Flex PSUs can be used in gaming PCs, but there are a few things to consider:

• Power Output: Make sure the wattage is high enough for your graphics card and CPU.
• Connectors: Check that the PSU has the right connectors for your components, especially if you have a dedicated graphics card.
• Cooling: Smaller PSUs may run warmer, so ensure your case has good airflow.

Flex PSUs are great for compact gaming builds, but always match the PSU's specs to your hardware needs.

Most flex PSUs include essential cables such as:

• Main motherboard power (20/24-pin)
• CPU power (4 or 8-pin)
• SATA connectors for drives
• Peripheral (Molex) connectors
• Sometimes a floppy connector

Some models are modular, letting you use only the cables you need. Always check the product description or packaging for a full list of included cables before purchasing.

To safely install a flex PSU:

1. Unplug your computer and discharge any static electricity by touching a metal surface.
2. Align the PSU with your case's mounting points and secure it with screws.
3. Connect the power cables to your motherboard, CPU, and drives as needed.
4. Double-check all connections before plugging in the power cord.

If you're new to PC building, consider checking your case manual or seeking help from a knowledgeable friend or a Walmart associate for extra guidance.
