My PSU is a 750 watt Corsair. I would have to open my computer case to check for a model number. My current graphics card is a 7800 series Radeon and my computer is about 5 years old. The graphics card I want only has 1 8 pin connector and requires 400 watts. Thanks for warning me off about the adapter cables because that would have been my next question. Would the computer motherboard be a problem where connections are concerned? Thanks for all the help.

The adapters may be "just wires" but the power supplies are not, and they do wear out over time. Here's an article about what can go wrong with power supplies https://www.electronicproducts.com/Power...e_about_it.aspxAlso think about the power requirements that would be expected of a molex as opposed to a graphics card adapter. A molex was usually used for a hard drive or optical drive, and its power requirements wouldn't go above a certain amount. The power requirements of a graphics card might spike a lot higher during a demanding game. So with the adapter, you'd have the graphics card attempting to pull more power than the power supply was designed to produce over those two molex connectors. Whatever components the molex connectors are connected to inside the power supply would be designed for a couple of hard drives, not a high end graphics card. These components might heat up enough to melt, blow, cause the power supply to shut down, etc., at the very least wear out a lot faster. Problems might not show up immediately, but chances are they would show up soon after playing demanding games. At the very least you'd wear out the power supply a lot faster and have to buy a new one anyway.

You shouldn't have any problem with the motherboard. The Radeon HD 7800 series has a PCI-e x16 3.0 interface, https://www.amd.com/en-us/products-site/Pages/desktop-graphics-7800.aspxThe Radeon 580 RX also has a PCI-e x16 3.0 interface. So if the HD 7800 works in your computer, so should the 580 RX. The first motherboard with PCI-e x16 3.0 slots came out in 2011 https://newatlas.com/msi-z68a-gd80-g3-motherboard/19158/So it's possible your 5-year-old motherboard might have a PCE-e x16 3.0 slot, especially if the computer was built as a gaming computer. Even if it only has a PCI-e x16 2.0 slot, the 580 RX card should work as long as the power supply supports it. If you know your motherboard model number, you can look up whether it has 2.0 or 3.0.
