Power supplies might not be as exciting as CPUs or GPUs but when you can get a top-rated 1000 W unit for just $130, you really can't ignore it

If there's one part of your gaming PC that you should never go cheap on, it's the power supply unit, or PSU. A high-quality unit will not only last for many years, but it will also keep your precious (and very expensive) components safe from unwanted electrical noise and power spikes.

Super Flower is primarily an OEM, in that it manufactures PSUs for other brands. Its own models are very understated, free of bling and RGB lighting. What they do have, though, is lots of high-quality components and a really solid design. Given that most PC cases hide the power supply anyway, the bland looks don't really matter.

If you want to know the specific details about its innards and operating parameters, you can read all about them in its Cybenetics certification. But for me, here's what matters the most, other than the fact that it's a Super Flower unit.

First up is the combination of the peak power rating and overall efficiency. As with almost all PSUs, this one is at its most efficient when loaded to around 50% of its peak power output—500 W in this instance. That makes it ideal for most mid-range or high-end gaming PCs, because unless you're using something like an RTX 5090, your rig is unlikely to average more than this.

Next up is the dedicated 12V-2x6 connector and cable. If you have a GeForce RTX graphics card that uses this socket (or its predecessor, the 12VHPWR), then you can dump any multi-cable adapter system you might be using and simplify everything to a single cable. This not only removes points of failure, but it also helps to reduce the likelihood of experiencing Meltygate with a high-end graphics card.

Lastly, the Super Flower Leadex III comes with a ten-year warranty. That's way longer than almost any other component in most gaming PCs, so you'll be fine to use it through multiple upgrades. Assuming you do keep it for that long, that works out to be equivalent to spending just one dollar per month.

Sure, it's nowhere near as cool or as exciting as a new processor or graphics card, but I know that I'd never have buyer's remorse picking up a Super Flower PSU.

Nick, gaming, and computers all first met in the early 1980s. After leaving university, he became a physics and IT teacher and started writing about tech in the late 1990s. That resulted in him working with MadOnion to write the help files for 3DMark and PCMark. After a short stint working at Beyond3D.com, Nick joined Futuremark (MadOnion rebranded) full-time, as editor-in-chief for its PC gaming section, YouGamers. After the site shutdown, he became an engineering and computing lecturer for many years, but missed the writing bug. Cue four years at TechSpot.com covering everything and anything to do with tech and PCs. He freely admits to being far too obsessed with GPUs and open-world grindy RPGs, but who isn't these days?
