This article covers MSI Z790 GAMING PLUS WIFI intel 第14・13・12世代 Coreプロセッサ対応 LGA1700 DDR5 ATX マザーボード MB6471.

Overview

The MSI Z790 GAMING PLUS WIFI is an ATX motherboard built around the Intel Z790 chipset, supporting LGA1700 CPUs from the 12th, 13th, and 14th generations. It brings DDR5 memory support, PCIe 5.0 on the primary x16 slot, and a robust 14+1+1 phase DrMOS power delivery system, making it a solid foundation for a mid-range gaming or productivity PC. With four M.2 slots (all PCIe 4.0 x4), 2.5GbE LAN, integrated Wi-Fi 6E, and a rear USB 3.2 Gen2x2 Type-C port, this board covers the connectivity essentials without breaking the bank. It sits comfortably in the entry-to-mid range of Z790 offerings, giving builders a cost-effective way to adopt the latest DDR5 platform.

Compatibility Guide

Socket: LGA1700 — compatible with Intel Core i9/i7/i5/i3 from 12th, 13th, and 14th Gen. Memory: 4x DDR5 DIMM slots, max 192 GB, with XMP 3.0 support. Form Factor: standard ATX (304.8 x 243.9 mm) — fits most mid-tower cases. PCIe lanes: 1x PCIe 5.0 x16 (primary), 1x PCIe 4.0 x4, 1x PCIe 3.0 x1, plus 1x PCIe 3.0 x1. Storage: 4x M.2 PCIe 4.0 x4, 6x SATA 3.0. Rear I/O: 1x USB 3.2 Gen2x2 Type-C (20 Gbps), 1x USB 3.2 Gen2 Type-A, 2x USB 3.2 Gen1 Type-A, 4x USB 2.0. Networking: Intel 2.5GbE LAN, Intel Wi-Fi 6E + Bluetooth 5.3. Audio: Realtek ALC897 7.1ch HD Audio.

Product Info

Released in late 2023, the MSI Z790 GAMING PLUS WIFI originally carried a suggested price around $200–$230, placing it in the entry-to-mid tier of Z790 motherboards. It provides a well-rounded feature set for the price: PCIe 5.0 support, decent VRM for most CPUs, and ample connectivity. Warranty: 2 years for Japanese authorized units.

Best Use Cases

Mainstream Gaming Builds: With PCIe 5.0 for the GPU and enough M.2 slots for fast storage, this board pairs well with an Intel Core i5-14600K or i7-14700K and a mid-range graphics card. It won't bottleneck typical gaming workloads. Not ideal for extreme overclocking or multi-GPU setups. Content Creation on a Budget: The four M.2 slots allow for a RAID array or fast scratch disk, and the USB 3.2 Gen2x2 Type-C port provides quick external transfers. Suited for video editors and photographers who need decent throughput without paying for a premium board. * Cost-Conscious Upgraders: If you're moving from an older platform to DDR5 and want a Z-series chipset without the premium price, this board delivers. It's a great option for building a new PC from scratch with a limited budget.

Things to Consider

Be aware that this board supports DDR5 only — no DDR4 compatibility. That means memory costs will be higher than with a DDR4 board. Also, the M.2 slots are all PCIe 4.0; there is no PCIe 5.0 SSD support, so if you plan to use a future Gen5 SSD, you'll need a different model. The VRM (14+1+1 phases, 55A DrMOS) is adequate for a Core i7-14700K under normal loads, but prolonged heavy multi-core workloads with a Core i9-14900K may push it to its limits. The onboard audio uses the Realtek ALC897 codec, which is functional but not audiophile-grade — consider a USB DAC if audio quality is a priority. ## FAQ
Q: Will this motherboard work with a Core i5-14600K out of the box? A: Yes, it supports all 12th, 13th, and 14th Gen LGA1700 CPUs without requiring a BIOS update. The i5-14600K is fully compatible. Q: Can I use a PCIe 5.0 graphics card? A: Absolutely. The primary PCIe x16 slot runs at PCIe 5.0, so you can install a GeForce RTX 40 series or Radeon RX 7000 series card and take advantage of the full bandwidth. Q: Does this board support DDR5-6000 memory? A: Yes, many DDR5-6000 kits are listed in the official QVL. Enable XMP 3.0 in the BIOS to run them at rated speeds. Always check the memory vendor's compatibility list for confirmation.
