A:AnswerYes I have the same board and a ryzen 3 3200g and it works fine, but if your are planning on using more than one case fan, you should get get a case fan splitter cable because there is only one system fan header on the board.
A:AnswerIt does. However if your motherboard does not have that configuration, they do sell a 24 to 6 pin converter that does work woth this power supply.
A:AnswerThis fits my 450 Watt tower and specializes in its quiet fan that is used only as needed. There was ample motherboard cabling and adequate add-on cables.
A:AnswerThis is a difficult question to answer without the actual specification list for your computer. I would lean towards replacing your PSU with one that is capable of the same wattage to what you are replacing.
When I searched 510a gaming the results were for home workstations. If you have a system without a dedicated GPU this PSU is more than enough. If you do have a dedicated GPU then I suggest you verify the entire system wattage requirements before purchasing this item.
A:AnswerIn checking the specs on your gigabyte b365m ds3h motherboard it appears to be compatible. It has old standard Molex power connectors as well as the new type. It has two different type of video connectors so be sure to use the right one.
I am using one on a ten year old Core 2 Quad DG33TL Intel motherboard and it is backward compatible for it.
GOOD LUCK!
