Building an AMD-based PC

It’s time to retire my 10.5-year-old desktop PC, which isn’t able to run Windows 11.

Much as I hate to abandon a company that has been passionate about DEI, I think it is time to switch to the AMD side (way better for gaming, which I’m not allowed to do; somewhat better for productivity).

Workload:

  • Adobe Premiere (not very frequently)
  • photo editing
  • training some AI models (if nothing else, I want to train and run a local AI model for photo library search)
  • general Web browsing
  • Zoom and Teams for work
  • Microsoft Office

Dreams:

  • 16 TB M.2 SSD (nobody seems to make this and thus the build below is what I think is the best 8 TB)
  • as many USC-C ports as possible (3 on the back and 1 on the front seems to be the limit; ASR LiveMixer motherboard below was picked to get beyond the standard 2 on the back)
  • reasonably compact case (currently have a Fractal Design Define 7 that is quiet, but absurdly huge)
  • quiet
  • built-in UPS that can handle outages of up to 30 seconds (typical Florida power outage is just a few seconds; I guess a 1-minute supply would be necessary to allow the machine to shut down gracefully if power is still out after 30 seconds; nobody makes this because consumers see that they can get 30 minutes out of an inexpensive desk-cluttering standard external UPS?)
  • built-in CD/DVD reader (will give up for compactness and plug in via USB-C)
  • built-in reader for SD and CFExpress cards (these don’t seem to exist either for 5.25″ or 3.5″ slots; there are some cheap/old readers that fit into 5.25″ slots that read old CF cards, but not CFExpress?)

Here’s my proposed build, with no case:

  • CPU: AMD Ryzen 9 9950X3D 4.3 GHz 16-Core Processor ($671.99 @ Amazon)
  • CPU Cooler: Cooler Master Hyper 212 Black Edition 42 CFM CPU Cooler ($29.99 @ Amazon)
  • Motherboard: ASRock X870 LiveMixer WiFi ATX AM5 Motherboard ($229.99 @ Amazon)
  • Memory: Corsair Vengeance 128 GB (2 x 64 GB) DDR5-6400 CL42 Memory ($359.99 @ Amazon)
  • Storage: Samsung 9100 PRO 8 TB M.2-2280 PCIe 5.0 X4 NVME Solid State Drive
  • Storage: Seagate BarraCuda 24 TB 3.5″ 7200 RPM Internal Hard Drive ($249.99 @ Newegg)
  • Storage: Seagate BarraCuda 24 TB 3.5″ 7200 RPM Internal Hard Drive ($249.99 @ Newegg)
  • Video Card: Asus PRIME GeForce RTX 5080 16 GB Video Card ($999.99 @ Amazon)
  • Power Supply: Corsair HX1000i (2023) 1000 W 80+ Platinum Certified Fully Modular ATX Power Supply ($239.99 @ Newegg)
  • Monitor: Samsung Odyssey Neo G95NC 57.0″ 7680 x 2160 240 Hz Curved Monitor ($1499.99 @ Abt)
  • Total: $4531.91

Questions:

  • what is the best case? It would be nice if it can hold one or two addition 3.5″ drives (maybe just move a couple from my old PC), but this isn’t essential
  • do I want the heat sink on the Samsung 8 TB M.2 SSD? It’s almost free and yet they sell the device with and without the heat sink (for mechanical fit?)
  • what is the right video card to get? I think RTX 5080 is what I want and I think that it will drive the crazy huge double-4K monitor, but I have no idea which brand video card makes sense (the ASUS was picked due to being reasonably cheap and available)
  • is the motherboard pick the right one? I might want to add a second M.2 drive some day. I can live with a max of 256 GB of RAM, I think
  • any other improvements?

  1. Re: built-in UPS

    Comes standard with every laptop and smart phone. I never bought one because they used lead-acid batteries. Maybe they are li-ion now? We were thinking about a natural gas backup generator, our power goes off for days (water too after an inland tropical storm wiped out our supply). I bought a new laptop with Windows 11about 3 months ago for $350 on sale.

    Re: DEI and intel

    Intel mentioned rolling back some of it’s DEI “progress” in its last annual report, joining the DEI-reversing bandwagon. Also, the U.S. just invested $9B for a 10% stake in Intel with some small change it found in the couch (unused Biden-era “CHIPS and Science” funds).

  2. Still a lot of money for a blog commenter. For that kind of money, who is actually going to use it? Greenspun doesn’t live permanently in FL but is a digital nomad.

  3. HDDs redundantly configured in RAID for reliability? Suggestion: don’t buy 2 HDDs from same manufacturer, buy from 2 different manufacturers. When a HDD fails, it’s likely from a defect that will occur in other HDDs from the same manufacturing lot. If you’ve got 2 HDDs from the same lot, your RAID could experience 2 concurrent failures = data loss.

  4. 3 x 28” monitors for me. 1 central focus (active work tools) + 2 periphery (1 email/web, 1 source documents) neatly matches and delineates my workflow.

  5. That is a lot of DRAM and disc space. If you want to do AI, it is the DRAM on the video card that matters. I would rather have an external disc server like Synology, or store data in a cloud service, with a fast internet connection.
    The UPS can be external. You can get a $10 usb reader for sd cards.

    • I need the RAM for Chrome! If present trends continue it will be 2 GB per open tab soon. I have an external UPS right now to deal with the occasional thunderstorm power glitch. I’d like to clear up my desktop.

    • The politically incorrect Brave browser reports 79.1MB for the philip.greenspun.com/blog page.

      The commenting system here doesn’t seem to use JS, because you can post with a text-only browser like links. That saves a lot of RAM. 🙂

  6. My PC is an old I5-3570 and runs windows 11-pro without any problem. The only advice is tu bien the iso in. USB stick with Rufus and the proper settings

    • Mark: Thanks. I’ve heard that it can be possible to install Windows 11 on hardware that doesn’t meet the official requirements. However, I use this machine for 1500+ hours per year (a depressing thought! So many hours sitting at a desk). It will be valuable to me if everything becomes more responsive (right now File Explorer can be quite slow, e.g., for renaming a file).

    • I’ve got an email to my brother, who knows a lot about custom PC builds. He’s hard to get a hold of, especially by me. If he gets back to me before you’ve made a decision, I’ll post his ideas.

      Have you tried NewEgg’s customer service to recommend a case? I mean you are spending a lot there, probably all AI, but you never know. https://kb.newegg.com/contact-us Might also be a retail PC builder near you, always good to support the locals.

      I can’t remember who offhand, but there are some modder fanatics on YouTube who review high-end cases. Probably a lot of goo to sort through with that route. 🙂
