The ASUS ROG Strix B850-E Gaming Motherboard delivers flagship-tier power delivery and feature density at a price point that undercuts X870E boards significantly. At £279.98, it represents excellent value for builders who want serious overclocking headroom, comprehensive connectivity, and ASUS’s refined BIOS without paying for features they won’t use. The AI-focused software additions feel gimmicky, but the hardware foundation is rock-solid.
What I Tested: Methodology and Setup
The ASUS ROG Strix B850-E arrived in early December and immediately became my primary testing platform. My evaluation process involved building a complete system around this board, running it through synthetic benchmarks, real-world gaming sessions, and stress testing to identify any thermal or stability issues. The test configuration included a Ryzen 9 9900X (12-core), 32GB Corsair Vengeance DDR5-6000 CL30, an RTX 4080 Founders Edition, and a 1TB Samsung 990 Pro in the primary M.2 slot.
Daily usage over four weeks covered everything from gaming marathons (Cyberpunk 2077, Baldur’s Gate 3, Counter-Strike 2) to productivity work in DaVinci Resolve and Blender. I tested ASUS’s AI Advisor feature, attempted memory overclocking beyond XMP profiles, and monitored VRM temperatures under sustained loads using both ASUS’s own software and HWiNFO64. The board also endured multiple BIOS updates to assess ASUS’s update process and any performance changes.
For comparison context, I’ve previously tested the GIGABYTE B850 EAGLE WIFI6E Motherboard and the ASUS ROG STRIX B550-F Gaming Motherboard, which provides useful perspective on both AMD platform evolution and ASUS’s product segmentation strategy.
Price Analysis: Premium B850 Positioning
Currently sitting at £279.98, the ROG Strix B850-E occupies interesting territory. It’s roughly £80 more expensive than budget B850 options like the GIGABYTE B850 EAGLE, but approximately £120 cheaper than entry-level X870E boards. The 90-day average of £289.39 suggests the current price represents a modest saving, though not a dramatic discount worth rushing for.
That price premium over basic B850 boards buys you tangible hardware upgrades: significantly beefier power delivery (16+2+2 phases versus 12+2+1 on budget boards), dual ProCool power connectors, premium audio codec, additional M.2 slots with heatsinks, and better VRM cooling. Whether those extras justify £80 depends entirely on your use case. If you’re running a Ryzen 5 7600X at stock speeds, probably not. If you’ve got a Ryzen 9 9950X and plan to overclock, absolutely.
The 2,893 customer reviews averaging 4.4 stars suggest most buyers feel the price is justified, though some criticism focuses on ASUS’s software bloat and the questionable value of AI features that feel more marketing than substance.
Performance and Features: Where the ROG Premium Shows
Power Delivery: Genuinely Overbuilt
The 16+2+2 phase power solution is the headline feature here, and it’s not just marketing numbers. Each phase is rated for 90A, giving you theoretical maximum delivery of 1,440A to the CPU. In practical terms, this means the board doesn’t break a sweat even with a power-hungry Ryzen 9 9950X running all-core workloads. During a 30-minute Cinebench R23 loop with my 9900X pulling 150W sustained, VRM temperatures peaked at 58°C – genuinely impressive for a passively cooled solution.
The dual 8-pin ProCool power connectors are overkill for most users but provide peace of mind for extreme overclocking. I tested with a single 8-pin initially and saw no issues, but the second connector does distribute current more evenly when pushing voltages beyond stock. The alloy chokes and high-quality capacitors feel like genuine premium components rather than cost-cutting alternatives.
Memory Overclocking: ASUS’s AEMP Delivers
AMD EXPO profiles loaded flawlessly with my DDR5-6000 kit, hitting rated speeds immediately. ASUS’s AEMP (ASUS Enhanced Memory Profile) technology attempts automatic overclocking beyond XMP/EXPO specifications, and it actually worked – pushing my 6000MHz kit to 6400MHz CL32 with complete stability. That’s not revolutionary, but it’s more than I achieved with the GIGABYTE B850 board’s auto-tuning.
Manual memory tuning through the BIOS is comprehensive if you know what you’re doing. The interface provides access to virtually every timing and voltage parameter, though beginners will find it overwhelming. I managed 6600MHz CL30 with manual tuning, shaving a few seconds off compilation times in my testing, though gaming performance differences were negligible.
Storage and Connectivity: Well Equipped
Four M.2 slots all include heatsinks, with the primary slot supporting PCIe 5.0. The 990 Pro in that slot showed no thermal throttling even during sustained file transfers. The remaining three slots run at PCIe 4.0 speeds, which remains plenty fast for current SSDs. Six SATA ports provide legacy storage options, though most builders will rely on M.2 these days.
USB connectivity is generous: dual USB 3.2 Gen 2×2 Type-C ports (one rear, one header), multiple USB 3.2 Gen 2 Type-A ports, and a USB4 header for case connectivity. The 2.5Gb Intel Ethernet proved stable and fast in testing, while WiFi 6E delivered strong wireless performance – though I stick with wired connections for my desktop.
Audio: Noticeable Quality
The SupremeFX 7.1 audio implementation uses a Realtek ALC4080 codec with Savitech amplification. Compared to basic motherboard audio, there’s a genuine quality difference – less background noise, cleaner output, better separation. It won’t replace a dedicated DAC for audiophiles, but for gaming headsets and mid-range speakers, it’s excellent. DTS Sound Unbound support adds spatial audio options for compatible games.
AI Features: Marketing Over Substance
ASUS heavily promotes AI Advisor, AI Networking II, and related software features. In practice, these feel half-baked. AI Advisor is essentially a chatbot that answers basic questions about your system – nothing you couldn’t Google in 30 seconds. AI Networking II supposedly prioritises gaming traffic, but I noticed zero difference in latency or stability compared to standard QoS settings.
The “AI PC Ready” marketing centres on USB4 connectivity and power delivery for AI accelerators, which is genuinely useful if you’re running local AI models. For 99% of gamers, it’s irrelevant. Don’t buy this board for AI features – buy it for the power delivery and connectivity.
BIOS and Software: ASUS’s Refined Experience
The UEFI BIOS remains one of ASUS’s strongest advantages. The interface is logically organised, responsive, and provides both simplified EZ Mode for beginners and comprehensive Advanced Mode for enthusiasts. Fan curves are easy to customise, with multiple temperature sources and curve types available. The Q-Fan tuning process accurately profiled my case fans and CPU cooler, creating quiet yet effective cooling profiles.
Armoury Crate software on Windows provides unified control over RGB lighting, fan speeds, and performance profiles. It’s bloated compared to competitors’ offerings, but it works reliably once configured. I disabled most of the background services after initial setup to reduce system resource usage. The MyASUS app adds remote monitoring via smartphone, which I found genuinely useful for checking temperatures during stress tests from another room.
Comparison: How It Stacks Against Alternatives
| Motherboard | Price | Power Phases | Key Advantage |
|---|---|---|---|
| ASUS ROG Strix B850-E | £279.98 | 16+2+2 (90A) | Best power delivery in B850 class |
| GIGABYTE B850 EAGLE WIFI6E | ~£190 | 12+2+1 (60A) | Budget-friendly with solid basics |
| MSI MEG X670E ACE | ~£390 | 18+2+1 (105A) | Flagship features, higher cost |
The GIGABYTE B850 EAGLE WIFI6E represents the budget alternative for builders who don’t need extreme power delivery. It handles Ryzen 7 and lower CPUs perfectly fine, but VRM temperatures climb noticeably with higher-end chips. Budget-conscious buyers running mainstream CPUs will find it perfectly adequate at £80 less.
Moving up to X870E territory like the MSI MEG X670E ACE Motherboard adds more PCIe lanes, additional USB4 ports, and marginally better power delivery, but you’re paying £120 extra for features most users won’t utilise. The ROG Strix B850-E hits a sweet spot for enthusiast gaming builds where you want premium quality without flagship pricing.
What Buyers Say: Real-World Feedback Analysis
Analysing the 2,893 customer reviews reveals consistent themes. Positive feedback centres on build quality, easy installation, and stable operation with high-end Ryzen CPUs. Multiple buyers specifically mention successful overclocking with Ryzen 9 9950X processors, validating the power delivery capabilities. The BIOS receives frequent praise for its intuitive layout and comprehensive options.
Common complaints focus on software bloat – Armoury Crate in particular divides opinion, with some users finding it useful while others immediately uninstall it. A handful of reviews mention initial boot issues that resolved after BIOS updates, suggesting early firmware had teething problems. RGB lighting control occasionally glitches, requiring software restarts to regain sync.
Price sensitivity appears in reviews from buyers who feel the premium over basic B850 boards isn’t justified for their use case. These typically involve Ryzen 5 or 7 CPUs running at stock speeds, where the enhanced power delivery provides no practical benefit. Conversely, enthusiast builders consistently rate the board highly, appreciating the headroom for future upgrades.
