BTF motherboards and reverse connectors: what they are, how they work
and why the Hiditec H3 PRO is the case that makes the most of them

You've spent years building PCs with a tangle of cables obscuring the motherboard, blocking airflow, and ruining the aesthetics of an otherwise flawless setup. BTF reverse connector motherboards solve exactly that problem. This guide explains from scratch what they are, which models exist, how to install them, and what your case needs to make the most of them—with the Hiditec H3 PRO as the answer to that last question.

If you've been watching builds on YouTube or social media and wondering how the inside of some cases is so clean—without the classic cable mess blocking the motherboard, without the 24-pin ATX connector running across the entire panel—the answer is almost always the same: they're using a reverse connector motherboard.

The technology has been maturing for a couple of years and in 2025 it's reached the mid-range market. It's no longer a luxury for €500 motherboards: you can build a BTF PC for less than a high-end traditional board costs. What you need is to know what to look for, what's compatible with what, and which case to pick so everything fits. That's exactly what we're going to explain here.

1. What is a reverse connector motherboard? The problem it solves

To understand what a BTF motherboard does, you first need to understand what a standard one does. In a standard motherboard, all power and data connectors are on the front side—the one you see when you open the case. The 24-pin ATX connector (the big one, the main power) runs from the PSU, crosses the entire interior of the case, and plugs into the right side of the motherboard. The 8-pin EPS connector for the CPU runs up to the upper left corner. SATA, USB, and fan connectors dot the entire visible surface. The result is a maze of cables you have to tame, hide, and zip-tie if you want the interior to look presentable.

The solution with BTF motherboards is so obvious in hindsight that it's surprising it took so long to arrive: move all those connectors to the back side of the motherboard. The side that sits against the case tray. The side nobody sees. The cables still exist—the PSU still delivers power to the motherboard—but instead of crossing the visible interior, they exit behind the tray directly toward the case's rear chamber.

There's an important detail to clarify: rear connectors aren't just aesthetic. By removing cables from the front space, airflow between the front fans, the CPU cooler, and GPU improves measurably. There are no physical obstructions interrupting the flow of cool air to the components. It's a real thermal advantage, not just a design consideration.

And there's another benefit that gets mentioned less: building becomes more accessible for beginners. With a standard motherboard, running the 24-pin cable behind the tray, tensioning it without pressuring the board, and keeping it straight without poking through gaps is an art that takes practice. With BTF, that cable goes directly to the rear connector without crossing anything. The mistake of "I forgot to connect the power and now I have to disassemble half the PC" becomes much easier to avoid.

2. The three BTF families: ASUS, MSI, and GIGABYTE

There's no universal reverse connector standard. Each manufacturer developed its own system with slightly different connector positions. This matters because your case needs to have slots in the correct position for your motherboard. The good news is that the Hiditec H3 PRO is compatible with all three major ecosystems.

ASUS BTF is the most complete ecosystem with the most models available in 2025. The lineup ranges from mid-range boards like the TUF B850-BTF to high-end ROG models, all with AM5. ASUS has also introduced the Advanced BTF standard, which adds a high-power PCIe connector in the GPU slot capable of delivering up to 600 W directly from the motherboard, eliminating the GPU power cable from the equation. You'll need a compatible BTF graphics card for this to work, but the direction the standard is heading is clear.

MSI Project Zero was one of the pioneers of the format and has a good selection of boards for both AM5 and Intel LGA1700. The MAG X870E Tomahawk Max WIFI PZ is especially interesting for Ryzen 7000/9000 users looking for a solid mid-to-high-range board without giving up rear connectors.

GIGABYTE AORUS Stealth completes the trio with competitive offerings in price and performance. The ecosystem has two standout AM5 models in 2025: the B850 AORUS Stealth in ATX format (with 14+2+2 phases, 4x M.2, and PCIe 5.0) and the B850M AORUS Stealth in Micro-ATX for more compact builds. For high-end, the X870 AORUS Stealth ICE is the reference with USB4, 5GbE, and Wi-Fi 7.

3. How to build with a BTF motherboard: step by step

Building with a BTF motherboard follows the exact same steps as any other PC, with one fundamental difference in how you connect the power. Here's the complete process for someone doing this for the first time with a case like the H3 PRO.

4. The Hiditec H3 PRO: the case that doesn't limit your BTF motherboard

Having a BTF motherboard is only half the equation. Your case needs to be designed for that ecosystem: if the tray doesn't have slots in the exact position of your motherboard's rear connectors, the system doesn't work. And if the case has the slots but a tiny rear chamber, cables have nowhere to go.

The Hiditec H3 PRO was designed specifically with this in mind. The tray has openings in the correct positions for all three major standards—ASUS BTF, MSI Project Zero, and GIGABYTE Stealth—and the space behind the tray is designed so rear cable management is comfortable, not an origami puzzle.

One detail that makes a real difference day-to-day is the tool-free side panel. On traditional cases, every time you need interior access you have to find a screwdriver and store the screws somewhere safe so you don't lose them. On the H3 PRO, the 4mm glass opens and closes with a tool-free latch mechanism—something that seems minor until you've built your second or third PC and realize you're not hunting for a Phillips head across your room.

The included ARGB controller with remote also deserves mention. You can connect all your ARGB fans to the case's internal hub and sync them without needing an RGB header on the motherboard or extra software—the remote controls lighting directly. For builds with many fans, this massively simplifies RGB cabling.
