If you’re operating in a 220–240V region and own a Japanese NEC PC-FX, you already know the limitation: the console was designed exclusively for Japan’s 100V AC mains. Using an external step-down transformer is mandatory—and often inconvenient, bulky, and not ideal for long-term reliability.

Tetsu no Onna is a purpose-built internal power conversion kit that eliminates the need for a step-down transformer entirely.

Overview

This kit replaces the original Japanese PSU with a modern DC-input power board. It accepts a standard 12V DC supply via a 5.5mm OD / 2.5mm ID barrel connector, providing clean and regulated power directly to the console.

• Fully compatible with Type-A and Type-B PC-FX
• True drop-in replacement
• No case modification required
• Designed for clean integration and long-term reliability

Installation

• Requires basic DIY skills
• Phillips screwdriver
• Torx T10 screwdriver

A guided installation tutorial is included.

What’s Included

• Custom power regulation board
• Barrel jack pre-installed in a precision 3D-printed snap-fit rear shell
• Genuine JST connectors

The rear barrel connector assembly is engineered to snap neatly into the original back panel opening—no drilling, no cutting.

Key Features

• Reverse polarity protection
• Overvoltage protection (cutoff at ~13.8V)
• LED indicators:
  • Power good
  • 9V rail status
  • 5V rail status
• High-quality genuine JST sockets
• Drop-in compatibility with both PC-FX revisions

Power Requirements

You will need a suitable external DC adapter:

• Output: 12V DC
• Current: ≥ 2.5A recommended
• Connector size(option 1):
  • Inner Diameter: 2.5mm
  • Outer Diameter: 5.5mm
• Connector size (option 2):
  • Inner Diameter: 2.1mm
  • Outer Diameter: 5.5mm

Use a regulated, high-quality adapter for optimal stability.

This kit provides a clean, transformer-free solution for safely operating your PC-FX outside Japan—without altering the console’s chassis or originality.

==============================================================

🇪🇺 European Union customers

EU VAT is collected at checkout by Lectronz on our behalf using their IOSS registration. You should not need to pay anything extra on arrival.

⚠️ EU orders are limited to €140 (excluding shipping and tax) to keep your order under the €150 IOSS threshold. Orders above this amount lose IOSS protection and would be subject to border VAT collection plus a customs handling fee charged by your local courier — almost always slower and more expensive than placing two smaller orders. If you need a larger quantity, please split your order or message us first.

Note: Starting July 1, 2026, the EU is introducing a flat €3 customs duty per item on parcels under €150. This policy will be updated closer to that date.

==============================================================

🇺🇸 United States customers

US import tariffs are collected during checkout via Lectronz's Prepaid Duty (PDDP) system. You should not need to pay anything extra on arrival — the price you pay at checkout is the final price.

This covers the 10% Section 122 import surcharge currently in effect on goods entering the US (introduced February 24, 2026). US import rules have been changing rapidly since the de minimis exemption ended in August 2025, and prepaying duties through Lectronz is the cleanest way to ensure your parcel clears customs without surprise fees at your door.

==============================================================

🇬🇧 United Kingdom customers

No VAT is collected at checkout for UK orders, and Retrology Repair is not UK VAT-registered.

⚠️ UK orders are limited to approximately £135 (excluding shipping) to stay under the UK low-value consignment threshold. Orders kept under this value should not attract UK VAT or import duties on arrival. Orders above £135 would be assessed for VAT (20%) and potential customs duties by HMRC on import, plus a courier handling fee, so please keep your order under this limit. If you need a larger quantity, please split your order or message us first.

==============================================================

🇦🇺 Australia customers

Orders under AUD $1,000 enter Australia free of GST and duty. No additional fees on arrival. Australian orders typically arrive within 5–10 business days.

==============================================================

🇳🇿 New Zealand customers

Prices for New Zealand customers include 15% GST. Retrology Repair is GST-registered and a tax invoice will be provided with your order. No additional fees on delivery — domestic orders typically arrive within 2–4 business days.

==============================================================

🇨🇦 Canada customers

Standard tracked post via NZ Post / international courier. Canadian buyers may be charged 5% GST plus a courier brokerage/handling fee on delivery. These charges are set by the Canada Border Services Agency and the courier, and are outside our control. Estimated delivery is 7–15 business days.

==============================================================

🌏 Rest of the world

We ship to most countries worldwide. Estimated delivery is 10–25 business days depending on destination and customs processing.
