The PS5 Chips Are $200 on eBay… I Built a PC With One

Summary of technological concepts, product features, and findings

What the device is

• The video centers on the AMD BC-250, a small “console-like” gaming PC built around chips sourced from PS5/PS5-derived hardware.
• The chips were originally sold off from units failing QC (repurposed for crypto mining).
• AMD used “binning” to disable parts that don’t fully work, selling them as lower-power/variant models.

Where to get it / cost baseline

• Boards are commonly found on eBay for about $160–$250, sometimes including an SSD.
• The creator picked one for about $100, then priced a baseline as BC-250 + SSD.
• Typical build cost for a working system lands around $300–$500, depending on:
  • case
  • cooling
  • SSD
• Their build cost was about $386 (or roughly $350-ish with SSD-inclusive deals).

Assembly requirements / “guide” discovered

• There’s no owner’s manual, so the creator relies on:
  • Reddit
  • an online “quick start guide”
• The guide suggests essentials like:
  • M.2 SSD
  • Power supply
  • Cooling fans (often standard 120mm PC fans)
  • a method to mount fans/shrouds, since the board lacks straightforward mounting points

Cooling solution

• A core practical issue: no native place to attach fans.
• Workaround: 3D-printed fan shrouds to force airflow through the large heatsink.
• Alternatives mentioned:
  • pre-made cooling solutions
  • using a proper PC-style case (with purchasable cases online)

Power-on failure and fix (major troubleshooting section)

• Initial issue: the system would not power on after installing the PSU and attempting to start it.
• Root cause explanation:
  • ATX PSUs usually turn on when the motherboard shorts specific pins (the creator references pins 4 and 5) to signal power-on.
  • Because the BC-250 isn’t a normal motherboard, the power signaling needed an alternative.
• Fix options described:
  • a specialized toggle/switch PCB solution
  • a “janky” workaround using a cable tie to connect the PSU “on” pins
• After applying the pin-connection workaround, the board powered on successfully.

Operating system constraints

• Zero Windows drivers, so Linux is required.
• Anti-cheat games (examples: Fortnite, Valorant) won’t work as expected.
• SteamOS is used (Valve’s gaming distro).
  • Caveat mentioned: SteamOS gaming distro support is noted as AMD GPU–only, which is acceptable here.
• Video output limitation:
  • the device has only one video port type: DisplayPort
  • TV use requires DisplayPort → HDMI conversion

SteamOS networking issue

• SteamOS failed to detect Ethernet, halting setup.
• Framed as a known SteamOS issue: devices without Wi‑Fi may have networking problems.
• Workaround:
  • use emergency/terminal modes (including multiple “emergency terminals” and shortcuts like Ctrl+Alt+F4)

Gaming performance testing (practical results)

• Tested across triple-A and indie games on the BC-250 + SteamOS setup.
• Common quirks:
  • no built-in wireless, so controller/Wi‑Fi need external Bluetooth/Wi‑Fi receivers
  • refresh rate issues: the creator repeatedly had to manually set refresh rate; games often default incorrectly (a recurring issue across displays)

Example results

• Forza Horizon 5: smooth play; about 75–90 FPS on a 1440p monitor at high settings, with minimal stuttering.
• No Man’s Sky: roughly ~75 FPS.
• Satisfactory (UE5-powered): about ~70 FPS.
• Satisfactory (another run/setting): around ~50 FPS (not treated as disastrous given beta status).

“PC usage” limitations / home-theater warning

• SteamOS desktop experience is described as somewhat annoying but workable (even for tasks like paying taxes).
• For other workloads (video calls, editing, servers like Jellyfin):
  • video encoding/decoding hardware is disabled
  • enabling firmware is Sony proprietary, and not expected to be opened publicly
• Conclusion: it’s not a good home theater PC because video decode/encode support isn’t accessible.

Free performance unlocks via software hacking (major “tuning” section)

• The video claims BC-250 performance can be improved for free via software unlocking/patches because the hardware was originally “binned.”

GPU governor unlock

• Default GPU frequency cap cited: ~1500 MHz
• Unlock supposedly improves scaling:
  • idle down to ~1000 MHz
  • boost up to ~2300 MHz depending on the chip
• Expected benefit: more headroom and better power behavior
• Outcome:
  • the creator couldn’t exceed ~2150 MHz without crashes
  • still saw improvements (e.g., Forza reaching 60 FPS in 4K after clock tweaking)

Unlocking disabled GPU compute units

• PS5 chip description: guaranteed set of working compute units (e.g., 36 of 40).
• The BC-250 reportedly uses 24 compute units (~60% of capacity).
• Patches may unlock additional compute units up to 40 (if the board supports it).
• Outcome: they only got four extra cores, judged not worth it (though better boards may yield more).

Patch drop during filming

• A new patch appeared unlocking two dormant CPU cores mid-video.
• Reported impact:
  • CPU core unlock produced a bigger performance difference than GPU governor changes
  • GPU governor was described as more stabilizing than boosting
• Caveats:
  • works through soft reboot
  • if the board powers fully off, the user must re-apply the patch
  • exploit is wrapped into a simple script, but it’s still annoying

Overall verdict/theme

• The BC-250 can roughly match PS5-like performance for a much lower price.
• But it’s presented as a tinkering system, not a plug-and-play console replacement:
  • “Lovable, complicated, not perfect”
  • requires time, setup work, and troubleshooting
