Do you have you a question about the ASRock DeskMini A300 Mini PC Barebone for Socket AM4?

Q: This doesn't seem to use standard SATA connectors so wondering if this comes with the appropriate cables in the box? Thanks.
Answer by Website User on 2nd July 2019
This uses m.2 drives for storage, these do not use cables, these go straight onto the motherboard.

A motherboard is included, using a chipset specifically designed for small form factor systems called the A300 - this is neither B350 nor B450. More information an the A300 chipset used in this product can be found here ->

Great bit of kit, using a 2200g apu and stealth cooler and it is whisper quiet. Can't believe you can have a gaming rig in such a small enclosure.

Great little mini PC that's really easy and quick to build for office work and light gaming. Best paired with a Ryzen 2400G and it'll support 3400G (with BIOS 3.50 installed) when that releases. Ideally, you should have 3000MHz RAM installed but I currently have Corsair Vengeance 2x8GB 2400MHz CL16 and it works plenty well for my needs. Although if you know your stuff when it comes to overclocking then you should definitely do that!

I am delighted with this computer for a number of reasons. I wanted a small computer to run Arch Linux as an upgrade to my Intel NUC Celeron system. The A300 is for AMD CPUs and they are cheaper than Intel. Fitting the Ryzen 2200G (with Vega integrated graphics) and the stock cooler (the one that comes with the A300, not the Wraith Stealth which won't fit) was straightforward. Adding some DDR2400 RAM was simple and I fitted a 240GB SSD on the underside of the mainboard. The barebones comes without wifi which I fitted as an option. The only problem with that is connecting the tiny aerial studs onto the card - nightmare! I also fitted the optional twin USB 2.0 option on the side - easy. With these items fitted, it's a tight squeeze getting the board back into the case. It needs a little bit of easing and helping the USB 2.0 cables to sit correctly. All-in-all, I am very pleased with my choice. I have two minor points of dissatisfaction. First the A300 cooler fan is a little noisy. Secondly, the audio mic/headphones output is on the front. There is an option to fit one to the rear but this appears to be unavailable in the UK. The service from CCLComputers was also very good.
