Priority AI Monster Upgrades (Color-Coded by Urgency)
📋 Recommendations reviewed 7 Aug 2026 — priorities changed
Every recommendation below was re-checked against live UK pricing and this machine's actual hardware. Three verdicts changed. Storage is now the only urgent buy; the PSU and motherboard upgrades were dropped after the numbers didn't support them.
🔴 Bulk storage: LOW → #1 (C: ~3% free)
🟢 2TB NVMe: pick changed to WD SN850X (~£100 cheaper)
🟡 PSU 850W: MEDIUM → not needed
⛔ X670E board: LOW → recommend against
⚠️ RAM to 96GB: must replace, not add sticks
📈 Market: SSDs +147%, DDR5 +110% YoY
✅ COMPLETED
RAM UPGRADE - COMPLETED! 🎉
UPGRADE EXECUTED: You upgraded to a matched Corsair Vengeance 2x 24GB DDR5 5200MHz kit (CMH48GX5M2B5200C38) for 48GB total! A matched dual-channel kit with 2 slots still free for future expansion.
Performance Achieved (48GB Total):
✅ Can load larger AI models (40B+ parameters)
✅ Matched dual-channel kit - full speed, no mixing
✅ Total: 48GB (2x 24GB DDR5 5200MHz CL38)
✅ 2 slots free - expandable to 96GB!

RAM Upgrade Completed! ★ INSTALLED
Corsair Vengeance 2x 24GB DDR5 5200MHz = 48GB Total
COMPLETED ✅
2 of 4 slots free
🚀
Future: 96GB via 2x 48GB Kit ⚠ REPLACE, DON'T ADD
Do NOT fill the 2 free slots — AM5 daisy-chain topology drops 4-DIMM DDR5 to ~3600-4800 MT/s. The correct path is swapping to a matched 2x 48GB kit, keeping 2-DIMM speed.
~£300+ • ⛔ BAD TIME TO BUY (DDR5 +110% YoY)
48GB is ample for now
✅ COMPLETED
💾 NVMe Storage Upgrade - INSTALLED! 🎉
ADDITIVE APPROACH EXECUTED: You added the Samsung 990 PRO 1TB NVMe M.2 to your existing 512GB SATA SSD for 1.5TB total storage! Fast NVMe for OS and AI models, plus the SATA drive for additional storage.
Performance Achieved:
✅ 7450 MB/s read / 6900 MB/s write speeds (NVMe)
✅ Lightning-fast AI model loading
✅ RGB heatsink for thermal management
✅ 1.5TB total (512GB SATA + 1TB NVMe)
⚠️ C: is down to ~31GB free of 930GB — this is now the system's real bottleneck
🔥 2026 Buying Reality Check
NAND/DRAM are in an AI-driven supercycle — retail SSDs rose ~147% and DDR5 ~110% over the past year
TrendForce expects prices to keep climbing through Q3/Q4 2026 — "wait for a dip" is not a reliable plan this cycle
Because C: is nearly full, this is the one upgrade worth buying despite the bad pricing
The free M.2 slot is Gen4 x4 — do not pay a premium for a PCIe 5.0 drive, this board can't use it
💾
WD_BLACK SN850X 2TB ★ BEST VALUE 2026
PCIe 4.0 x4 • 7300MB/s read / 6600MB/s write • M.2 2280 • fits the free Gen4 slot. Within 2% of the 990 PRO for ~£100 less — the value pick flipped from Samsung to WD this year.
PREMIUM COOLING INSTALLED: You've upgraded to the Corsair iCUE LINK TITAN 280 RX RGB! This is a beast of a cooler with a 280mm radiator, dual RX140 RGB fans, and the revolutionary iCUE LINK system for easy cable management and RGB control.
Performance Achieved:
✅ 280mm radiator for superior cooling capacity
✅ 2x RX140 RGB fans with customizable lighting
✅ iCUE LINK system hub included for easy management
✅ Compatible with Intel LGA 1851/1700, AMD AM5/AM4
✅ Sleek black design with premium RGB
✅ No thermal throttling - sustained AI workload performance!
❄️
Corsair iCUE LINK TITAN 280 RX RGB ★ INSTALLED
280mm AIO • 2x RX140 RGB Fans • iCUE LINK Hub Included • Intel LGA 1851/1700 • AMD AM5/AM4 • Black
Consider 360mm+ AIO or custom water cooling loop if you push extreme overclocks in the future

🟢 LOW #4 — NOT NEEDED YET
⚡ PSU Upgrade to 850W+
REVIEWED — DOWNGRADED: The earlier "750W may limit performance" claim doesn't survive the numbers. The RTX 5070 Ti is a 300W TGP card and NVIDIA's own spec calls for a 750W PSU; with the 65W-TDP (~90W PPT) Ryzen 7 7700 this build peaks around 450-480W including transients. You're at roughly 60% load on a Gold unit — its efficiency sweet spot. Don't spend £140 to fix a non-problem.
When this DOES become worth doing:
Only if you move to a 5080/5090-class card (360-575W TGP)
Only if you add a second GPU for parallel inference
If your current unit is out of warranty and ageing (caps degrade ~7-10 yrs)
Adding NVMe/HDD costs ~5-10W each — irrelevant to your headroom
⚡
If/when you do upgrade: Corsair RM850x 850W 80+ Gold
Fully modular • 80+ Gold • 10 yr warranty • native 12V-2x6 on current revisions. Still the sane default — one of the few components NOT hit by the 2026 price surge.
£139.99 RRP • often ~£110-130 street (was £129.99 — roughly flat)
REVIEWED — PROMOTED: This was rated "LOW", but a live check of the machine shows C: at ~31GB free of 930GB (~3%). Windows wants 10-15% free to page and defrag comfortably, and a single 40B-class model in Q4/Q5 GGUF is 25-30GB — you currently can't pull one down. Cheap spinning rust for cold storage (datasets, outputs, archives) frees the fast NVMe for the models you actually load.
Performance Impact:
Restores headroom on C: — biggest single quality-of-life win available
Store multiple large AI models locally
Keep datasets for training/fine-tuning
Archive generated content and outputs off the NVMe
5 free SATA ports — no compatibility work needed
💿
Seagate IronWolf 4TB NAS HDD ★ CHEAPEST FIX
CMR • 256MB cache • rated for 24/7 • drops into any of your 5 free SATA ports. Note: the 4TB IronWolf is 5400RPM class, not 7200 — irrelevant for archive/cold storage.
You have 78GB free on D: (476GB) and an F: backup drive. Move model caches off C: before spending anything — HuggingFace (HF_HOME), Ollama (OLLAMA_MODELS), ComfyUI checkpoints, and pip/npm caches are the usual multi-hundred-GB culprits.

⛔ #6 — DON'T BUY
🏠 Motherboard Upgrade
REVIEWED — RECOMMEND AGAINST: At ~£420-476 this is the worst £/performance item on the list for your actual workload. A single-GPU inference box gains essentially nothing from X670E: your RTX 5070 Ti at PCIe 4.0 x16 loses ~1-2% versus 5.0, and the B650M-P already gives you 2x M.2 Gen4 slots (one still free) plus 4 DIMM slots supporting up to 192GB. VRM load from a 65W 7700 is trivial. It's also a swap-everything job — full reinstall risk for no measurable gain.
