A modder has reworked the original Sony PlayStation to output via HDMI, draw power over USB, and pair with wireless controllers. The project strips away the 30-year-old cabling bottleneck—composite video, proprietary AV multi-out, and wall-wart power—without replacing the internal motherboard or emulation. It is a hardware preservation play, not a software emulation box.
Why This Mod Exists Now
Original PlayStation hardware has a finite lifespan. Disc drives fail. Capacitors leak. The stock video output is tied to analog standards that modern displays handle poorly, introducing input lag through internal deinterlacing or rejecting the signal outright. The common workaround—using an upscaler like a RetroTINK or OSSC—adds a secondary box, more cables, and configuration friction.
This mod targets that specific pain chain. By routing clean digital video directly to an HDMI port on the console shell, the display handshake becomes identical to any modern device. USB-C power removes the external brick. Wireless controller support eliminates the need to source increasingly brittle original pads. The core logic: make the original hardware frictionless to use on a 2026 desk or TV stand, rather than building a shrine to it in a closet.
The trade-off is immediately apparent. You are soldering to a working board. The mod is irreversible in its physical changes—holes drilled for ports, traces cut or rerouted. If the execution fails, you have damaged a console that is appreciating in value. This is not a software toggle you can revert.
How the HDMI Output Actually Works
The PlayStation's GPU generates a digital video signal internally before the console's encoding chip converts it to analog composite or S-video for output. The mod taps the signal before that conversion—pulling the clean digital data and feeding it into an HDMI encoder board mounted inside the chassis.
This is the critical distinction from analog-to-digital converter boxes. An external upscaler is re-digitizing an already degraded analog signal, then applying processing to clean it up. The internal HDMI mod never loses the signal quality in the first place. The result is a pixel-accurate image with zero added processing latency. The board handles HDCP handshake and audio embedding as well, so the single HDMI cable carries both video and sound to the display.
Resolution behavior depends on the encoder board used. Most implementations lock to the PS1's native 240p for standard titles, outputting it at a scaled resolution the display accepts—typically 720p or 1080p with integer scaling. High-resolution modes in a small number of titles (like *Ridge Racer Type 4* or *Tekken 3*) are handled differently depending on the board's firmware. [Inference: The specific board used in this project likely follows the established standard of 240p-to-720p integer scaling, as that is the prevailing approach in the modding community, but the source does not specify the exact scaler chipset.]
USB-C Power: Removing the Wall Brick
The original PlayStation power supply is an external transformer delivering 7.5V DC. The mod replaces the barrel jack input with a USB-C port and an internal voltage regulation circuit. You power the console using a standard USB-C PD (Power Delivery) cable and a sufficiently rated brick—the same one charging your phone, laptop, or Switch.
The practical benefit is cable consolidation. The convenience downside is power delivery negotiation. Not every USB-C brick outputs the correct voltage profile, and cheaper cables that lack proper PD negotiation can cause intermittent power drops under load. Disc spinning spikes current draw; a cable that works in a low-power test can fail when a game actually loads. The mod requires a quality PD brick rated for at least 15W-18W output, which is standard but not universal across every cable-and-charger combo in a drawer.
Wireless Controller Support
The original controller port is a proprietary serial connection. The mod adds a small Bluetooth receiver board internally, wired to intercept the controller communication lines. Original controllers can still be used by plugging into the stock port, but a paired wireless pad (commonly a DualShock or DualSense mapped via firmware) becomes the primary input method.
Input latency is the obvious concern. Bluetooth adds a small amount of inherent latency compared to a wired connection—typically 2-4ms under good conditions. For the vast majority of PS1 game libraries, this is imperceptible. For frame-tight rhythm games or *Tekken 3* at high-level play, it is a measurable disadvantage against a wired original pad. The mod does not force wireless; the original port remains functional, which is the correct design choice. You select your input method based on what you are playing.
The Irreversibility Question
Every hardware mod lives on a spectrum from plug-and-play to permanent alteration. This project sits firmly on the permanent end. The console shell requires cutting for the HDMI and USB-C ports. The internal board requires soldering to surface-mount components on the motherboard. Even if you desoldered everything later, the board traces would be damaged and the shell would have non-factory holes.
A working, clean original PlayStation in 2026 has real collector value. A badly modified one is worth significantly less. The decision arithmetic is blunt: do not perform this mod on a console you are not willing to destroy. The correct donor is a unit with a failed disc drive, a yellowed and cosmetically poor shell, or a board with other pre-existing issues that make it a poor candidate for stock preservation anyway. Buying a pristine working unit to modify is the wrong move financially and preservationally.
How This Compares to Other Approaches
Software emulation (PC, MiSTer, RetroArch): Near-zero cost, massive convenience, supports upscaling and save states. Loses the original hardware entirely. Not the same product—this is for people who specifically want the original silicon running the original discs.
External upscaler (RetroTINK-5X, OSSC): No modification to the console. Plug the stock composite or S-video into the box, HDMI out to the display. Adds a separate device and cables. Image quality is excellent but still subject to the limitations of the analog source signal being re-digitized. Best option if you want zero console modification.
Plug-and-play HDMI mods (pre-made boards like PS1Digital): Similar digital-signal-tap approach, but sold as a finished kit with instructions. Less custom work, but still requires soldering and shell modification. The YouTuber project appears to be a custom implementation rather than an off-the-shelf kit installation, suggesting bespoke board design or unusual integration. [Inference: The novelty in this specific project likely lies in the integration of all three mods—HDMI, USB power, and wireless—into a single cohesive build, rather than inventing a fundamentally new HDMI method.]
This mod: Maximum integration, single-cable-to-display convenience, original hardware retained. Highest execution risk, irreversible, requires actual soldering skill.
Practical Guidance for Anyone Considering This
- Source a junk donor console. Bad disc drive, cracked shell, missing controller port cover—ideal. Do not use a clean, working unit.
- Verify your soldering competency beforehand. This is not a beginner kit. You are working on a 30-year-old multi-layer PCB with surface-mount components. Lifted pads and damaged traces are the failure mode.
- Use a known-good USB-C PD power brick. Test it with a power meter before connecting the console. Do not assume any random charger will work.
- Keep the original controller port functional. The mod should wire in parallel, not replace. You want the option to go wired for latency-sensitive titles.
- Test the HDMI output before closing the shell. Boot a known disc, verify stable image across multiple resolution changes if possible. Reassemble only after confirming a solid signal.
Frequently Asked Questions
Does this mod improve the PS1's resolution or framerate?
No. The internal GPU and CPU run at their original speeds. The HDMI output scales the native 240p image to a modern display resolution, but it does not render additional pixels or add frames. Games run exactly as they did in 1994, just displayed more cleanly.
Can I still use original discs?
Yes. The mod does not touch the disc drive or the CD controller. The console reads original game discs normally. The HDMI, power, and controller mods operate independently of the disc subsystem.
Will this work with a PSone (the smaller redesigned model)?
Not without significant adaptation. The motherboard layout, power input location, and internal space are completely different between the original "gray brick" PS1 (SCPH-100x through 900x series) and the PSone (SCPH-10x). The mod as described is designed for the original chassis. [Inference: Adapting it to the PSone would require a separate board layout and different shell modification points.]
Is the audio output through HDMI good enough, or do I need separate audio cables?
The HDMI encoder board embeds the console's analog audio into the digital HDMI stream. Quality is functionally transparent for PS1-era audio, which was sampled and mixed at relatively low fidelity by modern standards. You do not need separate analog audio cables for typical gameplay use.
Can I buy a pre-modded console like this?
The specific YouTuber build shown is a custom project, not a commercial product. However, similar HDMI mods using established kits (like the PS1Digital) are available as paid installation services from various modding communities. You are paying for labor and the kit cost, and the seller's execution quality varies. Research the specific modder's reputation and warranty terms before buying.
