A solid PSU for most systems.

If you're in need of a fully modular PSU as an upgrade to an existing system, or as a foundation for a new one, I may well have found a solid option for you. This 650W MSI MAG A650GL option is available for £65 from Amazon, which is a great price on a reputable unit with solid wattage for most systems, and is at its best price in months. We've seen it drop to £65 before, at Black Friday 2025, and to have been able to get it for a lower price, you have to go back to Black Friday 2024!

650W of power may not seem like all too much, but it's enough for powering a potent 1080p or 1440p machine, providing ample power for an RX 9060 XT and an RTX 5060 Ti with solid headroom. According to MSI, you can also even get an RTX 5070 or even an RTX 5070 Ti in a system with a 650W PSU, if you don't pair it with a power-hungry CPU, that is. With this in mind, it's important to note the minimum requirements of the GPU in your system, and other components' power draw. It means you can build a surprisingly beefy system with this more modest wattage unit, although you always want to give yourself some headroom with a PSU for efficiency and potential room for upgrades without having to swap the unit out entirely.

This MSI unit is 80+ Gold rated, which is testament to its solid efficiency, while being fully modular means you only need to plug in necessary cables, preventing any horrible cable spaghetti. It's more of a benefit than you might initially think, and just keeps your build looking as clean as possible with only the cables you need.

If you want to grab a solid, reliable PSU with decent power for a rather low price, look no further than this Amazon deal on the MSI MAG A650GL.
