I'm planning a gaming PC with a Ryzen 7 7800X3D and GeForce RTX 5070 Ti, and those are the two parts I'd prefer not to change unless there's a compelling reason. The current build costs about $2,652. I'd like recommendations for reducing the price without sacrificing meaningful performance, and I also want to confirm that the components are physically compatible and will fit together properly. The current parts are a Thermalright Phantom Spirit 120 SE cooler, Gigabyte X870 AORUS Elite WiFi7 ICE motherboard, 32GB of DDR5-6000 CL36 memory, a 1TB Kingston NV3 NVMe SSD, Gigabyte Windforce OC SFF RTX 5070 Ti, Corsair FRAME 4500X case, and Corsair RM850x 850W power supply. Are there cheaper alternatives for the motherboard, RAM, storage, case, or PSU that would still be good choices?

The case and power supply are two easy places to cut costs. A well-ventilated mid-tower around $75–$90 will work fine, and an 850W ATX 3.x Gold-rated unit should be plenty for this system. Options such as the Montech Century II or MSI MPG A850GS could reduce the total substantially while still providing the required modern GPU power connection. The Phantom Spirit cooler is already an excellent value and doesn’t need to be replaced.
You may want to reconsider keeping that exact graphics card model. Other RTX 5070 Ti versions can be around $100 cheaper, including models from MSI, while delivering essentially the same performance. There have also been mixed reports about some Gigabyte GPU models, so comparing warranty support, cooler design, and pricing is sensible. The CPU and GPU can stay the same performance tier even if you choose different manufacturers.
A revised selection using a cheaper B850 motherboard, lower-cost DDR5-6000 CL30 memory, a more affordable case, and a less expensive 850W power supply brings the total down by roughly $260–$300 before changing the GPU. Switching to a cheaper 5070 Ti model could save another approximately $100. Everything should fit as long as the case supports the motherboard’s ATX format, the GPU length, and the Phantom Spirit’s cooler height; those dimensions should still be checked against the exact case specifications before ordering.
The motherboard is more expensive than necessary unless you specifically need the extra PCIe lanes, USB connectivity, or newer X870 features. A B650E, B850, or similar board should support the 7800X3D just as well for gaming and could save a significant amount. You can also use a less expensive 32GB DDR5-6000 CL30 kit; it has better timings than the current CL36 kit and should cost less. A faster, better-endurance 1TB NVMe drive may also be worth considering instead of the Kingston NV3.
I originally planned to keep the CPU and GPU because a friend recommended not changing them, but I’m open to alternatives if there’s a good reason. Thanks for showing that the graphics card model itself could be changed without giving up the 5070 Ti.
