Asrock B450M Pro4
If you’re looking to buy a motherboard that offers great bang for buck, ASRock is usually right at the top of the list. We often wonder how ASRock manages to churn out motherboards that undercut the competition by such large amounts. Perhaps it’s because it doesn’t spend mega millions on marketing? Whatever the reason, offering value is what ASRock does best, especially in the lower end of the market where a board like the B450M Pro4 is primed to compete well.
If you looked at the B450M Pro4, you’re unlikely to believe it costs around 145 bucks. It doesn’t have the bling of high end boards but at the same time, it compromises very little on features when compared to boards costing much more. Of course it’s a mATX board, but that doesn’t mean anything if you’re using it to host a typical single GPU system. It’s not totally devoid of bling either, as there is an RGB header onboard.
ASRock has included a single 8-pin CPU power connector that drives a nine phase VRM that is easily capable of powering the likes of the eight core 2700X. We frown upon push-pin heatsinks but at least they are made of metal and have enough surface area to cope with the demands of a little bit of overclocking. There’s four SATA ports and dual M.2 ports. The top most one supports NVMe drives with a PCIe 3.0 x4 connection, while the other supports a SATA based M.2 drive.
The rear I/O is the rst thing that caught our attention when taking the Pro4 out of its box. It’s got a set of ports that put some

more expensive boards to shame. There’s a total of eight USB ports consisting of a pair of 3.1 Gen 2 ports, one of which is a Type-C, plus four Gen 1 ports and nally a pair of 2.0 ports. There are headers for an additional four USB 2.0 and two 3.1 Gen 1 ports. Not bad at all! LAN duties are taken care of by a Realtek 8111H controller. The audio controller is also Realtek, speci cally the ALC892 codec. There’s a HDMI 1.4 port present; though we’d love to see a HDMI 2.0 port to get the best out of a Ryzen APU, but we can’t have everything at this price. Finally there’s a DVI-D port, PS/2 port, the three analogue audio ports and a VGA port, which hardly seems relevant in 2018.
Performance wise, the little ASRock did well. It fared particularly well in our multithreaded benchmarks, where it frequently came out on top, though the differences are small, as we expect all boards to be quite close to each other on a now mature platform.
Once again ASRock continues to enhance its already strong reputation for offering terri c value whilst not trimming down on essential features. If you’re on a tight budget, the ASRock B450M Pro 4 is a great choice. It allows you to divert extra dollars towards a higher end CPU or GPU, which is where the real performance differentiation is noticeable.
