Exactly as requested - the query asks about compatibility between an ATX power supply and a Micro-ATX motherboard, along with recommendations and a link to a product page.

The motherboard and PSU standards have changed independently. ATX requirements are explained differently for both components, and they aren't designed for seamless compatibility. The issue with your PSU relates to the case you're using with it. It's acceptable for an RTX 2060, but only as a basic budget option. Whether it makes sense depends on your plans for future GPUs that require higher power. It wouldn't be suitable for powerful models like the RTX 4080 or upcoming Nvidia/AMD versions.

i’ll admit i’m not sure about that PSU placement, it’s above the motherboard and looks bigger than usual. it doesn’t seem like a compact model, but it’s quite old. it probably isn’t a company anymore—looks like an office case. i won’t upgrade to an rtx 4080 or anything like that soon. instead, i’m thinking about getting an rtx 2060. i was looking at this link: https://www.amazon.com/MSI-GeForce-RTX-3...B0BL7Y69YP. but i’m leaning toward a 750W corsair PSU from amazon instead of the 650W from newegg.

I am confident in this setup. An ATX motherboard comes with 7 expansion slots, while a MATX model has 4. Both support an ATX power supply unit. The mix-up could happen if you're working with a compact case requiring a smaller ATX PSU. It’s unclear whether the I5-10400 and 3060 are compatible. Some games have CPU or graphics limits. Do you have any components ready? Do you have a budget in mind?
