Core i5-14400F best motherboard with 2.5GbE should be shortlisted around the job it must do. South African buyers should compare fit, performance, compatibility, and upgrade room, warranty path, and upgrade room before treating any pick as best.
The best 2.5GbE motherboard for the Core i5-14400F is the MSI PRO B760M-A WiFi DDR4 (R2,100 at Evetech) for mATX builds, or the MSI PRO B760-P DDR4 (R2,400) for ATX layouts. Both use Intel I226-V 2.5GbE NICs, provide dual M.2 PCIe 4.0 slots, and deliver enough VRM for the i5-14400F's 65 W base TDP. The 2.5GbE port saturates Vumatel and Openserve's 200–500 Mbps FTTH connections while providing 295 MB/s local NAS transfer speeds.
2.5GbE (2,500 Mbps) over standard Gigabit (1,000 Mbps) provides a 2.5× local LAN transfer speed increase. For an i5-14400F gaming PC in SA:
For daily gaming and internet use only, standard 1GbE is sufficient. 2.5GbE adds value in networked home environments.
| Board | Form factor | NIC chip | M.2 slots | Extra | Price |
|---|---|---|---|---|---|
| Gigabyte B760M DS3H DDR4 | mATX | Realtek RTL8125 | 2× PCIe 4.0 | None | ~R1,800 |
| MSI PRO B760M-A WiFi DDR4 | mATX | Intel I226-V | 2× PCIe 4.0 | Wi-Fi 6 | ~R2,100 |
| ASUS PRIME B760M-A D4 | mATX | Intel I219-V/2.5G | 2× PCIe 4.0 | AI XMP | ~R2,300 |
| MSI PRO B760-P DDR4 | ATX | Intel I226-V | 2× PCIe 4.0 | None | ~R2,400 |
All boards in the table handle the i5-14400F at 65 W without thermal stress. The Gigabyte DS3H has the lightest VRM (4-phase) but the i5-14400F's power draw is well within its capability at stock. For a stock-only build with no plans to upgrade to an i7 or i9 later, any board in the table is thermally adequate.
No — gaming latency (ping to game servers) is controlled by the ISP connection quality and routing, not by whether the home LAN is 1GbE or 2.5GbE. Both speeds comfortably handle the 1–10 Mbps bandwidth that online games require. 2.5GbE only affects local transfer speeds between devices on the same home network.
The i5-14400F has no integrated graphics — the "F" suffix indicates no iGPU. The HDMI and DisplayPort outputs on B760 boards are non-functional with the i5-14400F and only work with Intel CPUs that have Iris Xe graphics (such as the i5-14400 without the F suffix). Always connect your monitor to the discrete GPU's outputs.
Download the Intel Network Adapter Driver Package from Intel's support website rather than relying on Windows Update — the Windows Update version may install an older revision with latency issues. The Intel driver package (version 28.x or newer) resolves the early I226-V latency spikes reported in 2022–2023. After driver install, confirm the connection shows 2.5 Gbps in Device Manager.
B760 board with the i5-14400F, when you enable XMP in BIOS, also check whether the board automatically applies Intel's recommended Gear 1 or Gear 2 memory mode — Gear 1 at DDR4-3200 provides the lowest latency for gaming and is the correct setting for most DDR4 builds on LGA 1700.

NVIDIA lists 550W required system power for the RTX 5060 reference specification, based on a high-end test system. A quality 550W unit can be enough, but CPU draw, transient load, connectors and ageing decide real headroom.
80+ Gold vs 80+ Platinum for couch co-op gaming is about PSU efficiency, heat, fan behaviour, quality, and wattage headroom, not direct FPS. SA buyers should compare the whole build.

OpenRGB's master branch now carries changes labelled for 1.0 final, including translation and platform work, but the official tags page still lists 1.0rc3.1 as the newest packaged release. Stable users should wait for the signed release channel.
A motherboard can remain useful for many years when power, cooling and connectors stay healthy. Replace it for confirmed faults, damaged power delivery or a blocked platform need, not simply because the calendar reaches a fixed age.
The VAIO T combines a 13.3-inch display with a multi-flip mechanism for laptop, tablet and outward-facing viewing modes. Orders begin in Japan on 18 September; South African availability is unconfirmed.
The smallest ATX case 2026 buyers should choose is the smallest chassis that still fits their exact graphics card, cooler, power supply and airflow plan. ATX support alone does not prove a case has the smallest footprint or volume.
In a 6 bit + FRC vs 8 bit comparison, native 8-bit panels can produce 256 levels per colour channel directly, while 6-bit plus FRC rapidly alternates nearby values to approximate the wider palette. Panel quality still depends on more than bit depth.
The UGREEN LinkStation Pro eGPU dock combines Thunderbolt 5 and OCuLink connections with an integrated 850W ATX 3.1 power supply and up to 140W laptop charging. South African availability is unconfirmed.
Windows 11 KB5124008 can leave some USB Audio Class 1.0 devices with no sound, Code 10 or failed multichannel output. Microsoft confirms the issue and says switching to two-channel stereo can restore audio for some users.
