With a budget of 15k, you can still build a decent gaming PC around the Ryzen 5 4600G APU. Here's a suggested build that should offer good gaming performance within your budget:
1. Processor (APU): AMD Ryzen 5 4600G - This APU comes with integrated Radeon graphics, which should be good enough for gaming at 720p or 1080p resolutions on lower settings.
2. Motherboard: A budget B450 or B550 motherboard that is compatible with the Ryzen 5 4600G. Look for options from brands like MSI, ASUS, or Gigabyte.
3. RAM: 8GB (2x4GB) or 16GB (2x8GB) DDR4 RAM at 3200MHz or higher. Make sure to get a dual-channel kit for better performance.
4. Storage: A 240GB or 480GB SSD for your operating system and games, along with a 1TB HDD for additional storage.
5. Power Supply: A reliable 450W power supply from brands like Corsair, EVGA, or Seasonic should be sufficient for this build.
6. Case: Choose a budget-friendly case that fits your components and has good airflow for cooling.
7. Additional: You may need to allocate some of your budget for peripherals like a monitor, keyboard, mouse, and headset if you don't already have them.
Remember that prices may vary based on your location and availability of components. You can also consider buying some components second-hand to save money. Always make sure that the components you choose are compatible with each other to avoid any issues during the build process.
