Open-Source/Open-Hardware: Schematics, PCB Gerbers and firmware source code are available on Git.

It uses the standard Arduino bootloader and can be used with the Arduino IDE.

Firmware Upgradeable: the ATX2AT Smart Converter uses a standard MicroUSB connector and its firmware can be easily updated without special equipment.

You can easily build your own cable to power other retro-hardware.

Versatile: Outputs are located on a common 14-pins Molex MINI-FIT connector (same family than the 24-pin ATX connector).

Current filtering: All four power rails are filtered with long life & low ripple tantalum capacitors.

They’re mounted on fuse holders and are easy to replace if needed.

Failure-proof: sh*t happens! If, for some very unlikely reasons, the embedded micro-controller or the current sensor fails, the ATX2AT Smart Converter also includes two very fast acting fuses (10A on +5V and 5A on +12V) as a last-resort protection.

The PCB includes a 0.5% voltage reference. It also shows the actual current limits and warn you if an overcurrent is detected (also telling on which rail it occurred).

Current monitoring: real-time current monitoring is displayed on a small 0.96″ OLED display.

The ATX2AT Smart Converter integrates massive power MOSFETs able to cut the power by itself, without relying on the PSU. Moreover, even after they stop supplying power, their massive output capacitors can still discharge and make the damage worse.

Onboard MOSFET: PSU are sometimes slow to react to a shut down order.

Two PTC (resettable fuses) prevent damage in case of shorts on negative rails (100 mA on -5V and 500 mA on -12V).

-12V/-5V Protection: Negative voltages are sometimes used by some old extension cards and may also fail.

It can be used with your nice AWE32 Upgrade Card or any other card that requires -5V. Integrated -5V Converter: the ATX2AT Smart Converter uses a 79M05 regulator to generate the missing -5V rail on modern ATX power supplies.At 150 ms (still much faster than you), the “slow” option is usually enough to prevent any damage without false-positive triggering, but sometimes, the ultra-fast option may be useful. Configurable reaction time: both integrated “virtual fuses” can act as slow-blow or extremely fast-acting fuses.But you can also choose 1.50A/0.20A or up to 8A/4.75A. For example, 486 boards usually work fine with the default settings: 4.00A max for +5V and 500 mA (0.5A) for +12V. 8 different limits can be set with the dip switches. The ATX2AT Smart Converter monitors the current drawn on both rail in real time. But there is also some dramatic failures on the +12V rail, finding its way to the +5V and burning everything. +5V/+12V Programmable Over-Current Protection: Almost all pre-Socket 5 motherboard (from 8088 to early Pentium) drawn 90% of their power on +5V.Here is a description of the integrated features: It offers much more advanced and useful capacities than a standard passive adapter cable. The ATX2AT Smart Converter is dedicated to anyone who repairs or just want to protect their precious old hardware from disasters. It was originally designed for vintage PCs (with AT-Style power supply), but it can also work with old Macintosh as well as many other 70s/80s/90s computers, consoles, etc. You can set the current limits and define how quickly it will react to an overpower condition. It can be seen as a couple of programmable fuses with monitoring capabilities.

The ATX2AT Smart Converter plugs on a standard 24-pin ATX PC Power Supply and acts as an intelligent protection device for old retro-hardware. What is it? – A useful tool for everyone serious about retrocomputing!
