With a budget of 13k, you can definitely put together a solid Ryzen 5 2400G PC build that will offer good performance for gaming and everyday tasks. Here's a sample build you could consider:
1. Processor: AMD Ryzen 5 2400G
2. Motherboard: B450 chipset motherboard (such as MSI B450 Tomahawk)
3. RAM: 8GB DDR4 RAM (Corsair Vengeance LPX or G.Skill Ripjaws V)
4. Storage: 240GB SSD (Crucial MX500 or Samsung 860 EVO)
5. Power Supply Unit: 450W PSU (Corsair CX450)
6. Case: Budget ATX case (such as Cooler Master MasterBox Lite 3.1)
7. Operating System: Windows 10 Home
With this setup, you should be able to play most modern games at 1080p resolution with decent settings. However, keep in mind that you won't be able to use a dedicated graphics card with this build, as the Ryzen 5 2400G comes with integrated Vega graphics.
You can also consider adding more RAM or storage later on when your budget allows. Additionally, if you have any specific requirements or preferences, feel free to mention them so I can tailor the build accordingly.
