I've been looking in the internet for a graphics card that will work for my desktop and I think I found the one. The only question I have is if this graphics card low profile will be a problem. I also came here to confirm if this would work with my desktop and if there are any other suggestions. Thanks in advance

Yes it will fit just fine.
It comes with a standard size bracket installed. But it also has 2 low profile brackets included for use in a SFF case.
You did not state a use so I have to assume it is for better gaming. If that is the case then there are a lot better options available.

Both of these would way outperform your choice and work with your current 300watt power supply.
