Great board, for what it is 8/21/2020 2:41:34 PM

Pros: works
stable

Cons: the poor I/O and front panel connectors

Overall Review: Frankly. This is great. I love this board, and I think that it is very efficient at what it is for. I have been running it for almost a month now and I have never had an issue with it. All of the temps stay well within their bounds. Everything seems to be functional and effective. The few downsides to the board are that it has some slightly terrible I/O. The rear I/O is great, but the low number of other options is slightly different.

Good 550 motherboard 8/18/2020 1:27:46 AM

Pros: Motherboard is of good quality. Has 4 memory slots, sufficient pci-e, two m.2

Cons: The two PCIex16 and the PCIex4 are VERY close together. If you have a large Graphic card, you will lose a PCIex16, a PCIex4 and a m.2 by attaching your graphic card.

Overall Review: Good quality and did work

Great. 8/8/2020 12:48:00 PM

Overall Review: I bought an AMD RYZEN 5 3600 CPU and this MOBO at the same time, and both worked right out of the box. I will say it is very hard to use one of the SATA ports if you have a large video card, but it can be done if you use 90 degree-bend SATA cables.
