Choosing the right wattage for your PC power supply depends on the components you plan to use. To help you decide:

• Check your hardware: Add up the power requirements for your CPU, graphics card, and other devices.
• Consider upgrades: If you might add more parts later, choose a higher wattage for flexibility.
• Use online calculators: There are tools that estimate your total power needs based on your setup.
• Look for certification: Higher efficiency ratings can help reduce energy waste.

It's a good idea to have some extra capacity, but avoid going too high unless needed.

Modular power supplies let you connect only the cables you need, making your build cleaner and easier to manage. There are three types:

• Fully modular: All cables can be detached.
• Semi-modular: Some cables are fixed, others removable.
• Non-modular: All cables are permanently attached.

Modular designs help with airflow and cable organization, which can be especially handy in compact or gaming setups.

Yes, gaming power supplies can work in standard desktops as long as the form factor matches your case (like ATX) and the wattage fits your needs. Gaming PSUs often offer higher efficiency, better cooling, and modular cables, which can benefit any PC build. Just make sure your motherboard and other components are compatible with the connectors provided.

To check if a power supply fits your case:

• Look at the form factor: Most cases use ATX, but some need SFX or other sizes.
• Check dimensions: Compare the PSU's measurements with your case's specifications.
• Review mounting points: Make sure the screw holes and brackets match up.

It's helpful to review your case manual or specs online before buying to avoid compatibility issues.

If your power supply isn't working, try these steps:

1. Double-check connections: Make sure all cables are securely attached.
2. Test with another outlet: Sometimes the issue is with the power source.
3. Look for signs of damage: Check for burnt smells or visible wear.
4. Consult your warranty: Many PSUs come with coverage for defects.

If troubleshooting doesn't help, consider reaching out to the manufacturer or Walmart's customer support for guidance or replacement options.
