Ryzen 3700X compatible board featuring ample rear connections
Based on your needs, I’m seeking a solid board compatible with your Ryzen 3700X that offers ample rear I/O, especially USB-A ports. You mentioned the B450 Tomahawk Max is a strong suggestion, though it falls short in rear USB availability compared to the B350M you’ve used before. You’re aiming for at least seven USB-A connectors (with two capable of 2.0) and prefer built-in rear I/O over a PCIe card. Your backup idea is to use the Tomahawk Max with a USB PCIe expansion card, but having dedicated rear ports would be ideal.
7+ at the back? Consider using a bracket with 2x or 4x USB 3 ports. It’s the most affordable option and allows for reuse.
This was my fallback option if I couldn't locate a suitable alternative board for the Tomahawk Max. I'm not currently using it, but I'm planning an upgrade from my B350, which I've already used with a CPU upgrade. It's just to test first—functioning well until heavy usage. Regarding the x570, it seems you're curious about its compatibility. From the B450 Tomahawk Max manual (attached), it should support at least a 2.0 x1 USB card with the 3700X chipset, which has 16+4+4 pins. I have the Rosewill RC-508, a 2.0 1x slot, and I'm checking if that works as well.
B450M Bazooka plus, Gaming plus and x470 Gaming max together provide more than 4+4 USB3 ports. The setup likely hinges on a single additional connector.
