Component Breakdown Guide for RTX 5070 + Ryzen 7 9700X Builds

When you’re putting together a build like this, the supporting parts matter just as much as the CPU and GPU. Here’s how you should approach the rest of the components in your system.

RAM (DDR5)

8GB – No. It’s just not enough memory to support modern titles, which can lead to performance issues like stuttering, longer load times and major limits on multitasking.

16GB – Yes. A solid amount of memory that will handle 1440p gaming without issues. You’ll have enough memory for background applications like streaming applications and browsing.

32GB – Best. The smarter choice if you want to be future-proof and multitask comfortably. 32GB leaves you plenty of headroom for future games, content creation, and is definitely the safest choice.

Storage

HDD – Skip it. In modern gaming, hard drives speed is way to slow to run modern games, but if you have big files that aren’t gaming related like photos or videos, then HDDs are fine to store these files.

SATA SSD – Okay. Works fine, but you’ll notice slower load times compared to NVMe SSDs and upgrading to the next tier, “NVMe” storage isn’t much more expensive.

M.2 NVMe SSD – Yes. The clear winner here. Games load almost instantly, Windows boots fast, and you’ll want to start with at least 1TB worth of storage, 2TB is even better.

Motherboard

The B850 is a great fit for this system. It supports DDR5, PCIe 5.0, has dual M.2 slots for storage expansion, and comes with WiFi 7 plus 2.5Gb LAN. Basically, everything you need without paying extra for features you won’t use. To me, the B850 is the perfect balanced board for performance, without having to push into a higher price range.

Higher-end motherboards like the X870 offer more ports, stronger VRMs, and even more PCIe lanes. But it can be overkill in this particular build. The X870 is best if you plan to run multiple GPUs, or if you just want the highest on the line. But for this build, we recommend sticking with the B850.

Cooling

Stock cooler – No. Not enough for the Ryzen 7 9700X. At full boost you may experience higher temps, causing shorter lifespan for your components and possibly hardware malfunction.

Air cooling – Good. A quality option, you’ll want at least two or three intake fans at the front that pull cool air in and one or two exhaust fans at either the top or the back of the pc pushing the hot air out.

Liquid Cooling – Best. The most efficient cooling method, it’s quiet, and it ensures that your PC and CPU will remain cool when running demanding games. Look for either a 240mm or a 360mm Liquid Cooler, depending on your chassis.

Power Supply

650W PSU – Too Low. 650W just isn’t enough power to handle the RTX 5070 and the Ryzen 7 9700X.

750W PSU – Bare Minimum. It would work, but you’d be cutting it really close, and you would have no room to upgrade or even to overclock.

850W PSU – Perfect Choice. The perfect number to be at in my eyes, it still leaves plenty of room if you want to overclock, or if you want to make some upgrades in the future.

1000W PSU – Future Proof. 1000W would be overkill, but it would still work and give you a safety blanket if you’re planning to make consistent upgrades to your build, giving you a more future proof option.

Operating System

Windows 10 – Outdated. Support for windows 10 ends officially on October 14th, 2025, leaving you with an outdated operating system. It’s best to avoid Windows 10, and if you have Windows 10, try to upgrade to Windows 11.

Windows 11 Home – Good Choice. If you’re just going to be using your PC for gaming, Windows 11 Home is a good choice, it has all the functionality you need to be fully optimized for gaming.

Windows 11 Pro – Best Option. I always go with Windows 11 Pro due to the extra security features like BitLocker encryption and features like Remote Desktop. If gaming isn’t the only thing you use your PC for, I highly recommend Windows 11 Pro.

Summary

In this guide, we covered everything you need if you’re building a PC with the Ryzen 7 9700X paired with the Nvidia RTX 5070, down to how much memory you need, and which motherboard is best suited for this type of build.
