Yeah, okay, you’d rather splurge on a shiny CPU, GPU or SSD. We get it, but when it comes to building new, it pays to have a high-quality power supply in situ. While not the most exciting component, a well-engineered, forward-looking ATX 3.0 PSU will stand you in good stead.

Browsing the shelves this morning reveals the MSI MPG A850G PCIE5 as a deal worth knowing about. The name doesn’t exactly roll off the tongue, but the price does. Here in the UK, the supply has returned to a best-ever price of £109.99, while across the pond it’s $109.99 from Amazon. That’s the lowest we’ve ever seen for this particular model.

Better yet, MSI ticks all the relevant boxes. For a high-end build we typically recommend around an 800W capacity, preferably with 80 Plus Gold certification, guaranteeing over 90% efficiency at 50% load. A850G hits all those straps and is ATX 3.0-ready, allowing for single-12VHPWR connection to your meaty graphics card.

A single-rail design, 100% Japanese capacitors and flat, fully-modular cables round out a solid feature set. It’s also a reasonably petite unit, measuring only 150mm deep, making it suitable for a wide range of chassis, and the quiet 135mm fan will switch off entirely at low load. You’d do well to find a better-rounded supply at this price point.
