I second the AM5 suggestion if possible, but if you are strictly capped at $800, keep this Intel build! The SN770 is great, and the Montech Air 100 includes 4 pre-installed ARGB fans which saves you having to buy extra case fans. Just make sure to enable XMP in the BIOS on first boot.
Confirmed working with PS5. Just installed it and console benchmarked it at 6,550 MB/s formatted read speed. Fits under the slot cover with millimeter precision.
Super Flower is the OEM behind many of EVGA’s legendary SuperNOVA G2/G3 units. At under $100 for an ATX 3.1 Tier A unit with 10 year warranty, this is an absolute steal.
This is a known issue on several AGESA 1.2.0.0a / 1.2.0.1 BIOS releases with Phison E26 Gen5 drives! Two fixes will resolve this immediately:
1. Update BIOS to latest release with AGESA ComboAM5PI 1.2.0.2.
2. In BIOS -> Advanced -> PCI Subsystem Settings: Set CPU PCIe slot from ‘Auto’ to explicit ‘Gen 4’ (or disable PCIe ASPM Link State Power Management). There is virtually zero real-world speed difference, and it completely cures the WHEA 0x124 bus dropouts.
Your Corsair RM850x will easily handle the 7800X3D + RX 9070 XT. The 7800X3D draws ~55-75W during gaming, motherboard + peripherals ~50W. Even if the 9070 XT averages 320W with 450W 10ms transient spikes, you will stay well within the RM850x OCP trigger threshold (which sits around 1050W on that specific CWT platform). Save your money for games!
Yes, a quality 850W Gold rated power supply (Seasonic, Corsair RMx, be quiet!) is more than enough. The 9070 XT is expected to draw around 280-320W peak, and with an efficient AM5 CPU total system load will barely touch 500W in gaming.
