[Build Review] Ryzen 7800X3D + RTX 4070 Super Work/Gaming Setup — Compatibility + Longevity Check

Hi all — I’m upgrading my personal setup for dual-purpose use:
• UX design and productivity work (Figma, Notion, browser-heavy multitasking)
• Gaming (Valorant, immersive titles like Cyberpunk 2077 at high refresh rates)

My goals are performance, thermal efficiency, and long-term reliability. Would love your perspective on component synergy, BIOS flashback workflow, and airflow planning for this mATX case setup.

⸻

Current System (Being Retired):
• Intel i5 (8th/9th Gen)
• Gigabyte B360M D3H
• NVIDIA GTX 1060 WindForce
• 16GB DDR4 RAM
• Samsung 970 EVO NVMe SSD
• EVGA SuperNOVA G2 750W (retained)
• Thermaltake Core V21 mATX Cube Case (retained)
• Logitech G Pro Wireless, Razer Blackwidow
• No dedicated headphones
• Basic desk and office chair (non-ergonomic)

⸻

Upgraded Build Plan:
• CPU: AMD Ryzen 7 7800X3D
• Motherboard: ASUS TUF GAMING B650M-PLUS WIFI (mATX, supports BIOS Flashback)
• RAM: 32GB DDR5-6000 CL30 (TEAMGROUP T-Create Expert)
• GPU: NVIDIA RTX 4070 SUPER (Founders Edition)
• SSD: Samsung 980 Pro 1TB Gen 4 NVMe
• Cooler: Noctua NH-U12S chromax.black
• PSU: EVGA SuperNOVA G2 750W (Gold, modular)
• Case: Thermaltake Core V21
• Headphones: SteelSeries Arctis Nova Pro Wireless
• Desk/Chair: Desky Dual Hardwood Sit/Stand Desk + Desky Pro+ Ergonomic Chair

⸻

Primary Questions:
1. BIOS Prep – Will the B650M board’s flashback feature reliably support 7800X3D install out of the box? Tips for prep?
2. Thermal flow – With a Noctua NH-U12S and RTX 4070 Super, is the Core V21 cube layout sufficient? Should I add a rear exhaust or side intake fan?
3. Cable/power – Any benefit from upgrading PSU if I want to add a second NVMe + external devices later?
4. General balance – Is this setup overspending on GPU for 1440p OLED work/gaming use? Any other parts you’d rebalance?

⸻

Other Notes:
• System is meant to last 4–6 years minimum with modularity for work/gaming split.
• Looking at high refresh OLED for productivity + game immersion (monitor not yet chosen).
• Desk setup is ergonomically designed with cable tray, monitor riser, hidden wireless charger, and headphone hook — aesthetics matter as much as performance.

Would appreciate insight, especially from folks familiar with Ryzen 7000 + compact case thermal strategies.

Welcome to the forums!

System looks pretty solid, my comments:

CPU: Not a bad choice, although I would possibly put in a Zen 6 CPU once those come out in a year or two (wait ~six months for drivers etc to settle as usual). Also, you might want to consider the 7900 or 9900X as more cores are better for productivity (in general). If you are based in the US, Microcenter have crazy deals on Mobo + CPU + RAM.

GPU: Not the biggest fan of the 4070 - either step up to a RTX 5070 Ti or consider a Radeon card like the RX 7800 XT or RX 9070 XT. The price difference compared to what you get for the money is worth it.

SSD: 1TB SSDs are starting to feel cramped, especially for content creation. 2TB+ are highly recommended.

Motherboard: Very barebones, do consider an X870 ($200-ish) or B850 ($150-ish) as well. The Asus B650 ProArt Creator is one of the better ones on a budget, definitely make sure it has WiFi / Bluetooth, I just can’t live without it anymore even though I have threaded network, having my BT headphones connected to my phone AND PC at the same time? GAME CHANGER, I swear by it ever since :slight_smile:

As for your specific questions:

Yep, no problems at all - in theory. Power on before installing CPU, Flashback according to manual and then enjoy.

Two 140 fans in the front and one 120 in the back should be sufficient for those components and airflow.

Unless you really need the cables, not really. NVMe drives draw like 5-10W each or so, and mATX usually are pretty hard to max out on the power side.

It is pretty balanced in general, apart from what I mentioned above.

Have fun with the build :slight_smile:
