Compatibility Notes

Socket, memory, power, and case fit should be verified against retailer specifications before purchase.

Upgrade Path

The clearest upgrade path for this system lies in the CPU and memory. While the AM4 platform is mature, you can eventually drop in a Ryzen 7 5700X3D for a massive boost in gaming frame rates without changing the motherboard. Additionally, upgrading to 32GB of DDR4 memory and adding a second M.2 NVMe SSD will keep this system feeling snappy as modern games demand more resources.

Tradeoffs

To hit the aggressive $700 price target, we opted for the older AM4 platform and DDR4 memory instead of transitioning to AM5 and DDR5. The motherboard lacks built-in Wi-Fi, and the 650W power supply is non-modular, which requires extra effort for cable management. Additionally, the Kingston NV2 SSD uses QLC NAND, which is fine for gaming but slower during sustained heavy file transfers.

FAQ

Can this PC handle ray tracing?

While the RX 6750 XT supports ray tracing, it is best suited for traditional rasterized gaming. Enabling heavy ray tracing at 1440p will significantly impact frame rates, though upscaling technologies like FSR can help mitigate the performance hit.

Is the 650W power supply enough for this build?

Yes, 650W is more than sufficient. The Ryzen 5 5600 and RX 6750 XT have a combined power draw of around 315W under load, leaving plenty of headroom for transient spikes and system fans.

Does the motherboard support Wi-Fi out of the box?

No, the ASRock B550 Phantom Gaming 4 does not include built-in Wi-Fi or Bluetooth. You will need to use an Ethernet cable or purchase a separate PCIe Wi-Fi card or USB dongle.

Why choose AM4 in 2026 instead of AM5?

Choosing AM4 allows us to fit a powerful 12GB GPU like the RX 6750 XT into a strict $700 budget. Moving to AM5 would require more expensive DDR5 RAM, a pricier motherboard, and a costlier CPU, forcing a downgrade to a much weaker graphics card.
