Super Flower Leadex Platinum 550W Power Supply Review

Final Thoughts


The Super Flower Leadex Platinum 550W Fully Modular 80 Plus Platinum Power Supply can be picked up from most major retailers, and is currently available from Overclockers UK for a very reasonable £74.99. While that may seem a lot for a PSU of this power output, it’s an absolute bargain for a Platinum unit, with many manufacturers making 80 Plus Gold rated units for the same price!


Super Flower makes some of the best power supplies in the world and their Leadex Platinum 550W is a prime example of just how great they can be. To have the high-end performance of a much more expensive unit at a wattage and price range that would suit virtually any single GPU system configuration, with headroom for dual graphics cards on more modern and efficient GPUs is simply fantastic.

The performance figures of this unit just keep on getting better and better. Reliable voltage regulation, exceptionally low ripple (some of the lowest we’ve ever seen!), fantastic cool with virtually no noise and a hybrid/passive cooling mode that’s even quieter, great efficiency that will save you money in the long run, and finally, let’s not forget that it was able to exceed 800W power draw!

Picking the right PSU for your system can be tricky, knowing which wattage or efficiency to get for your budget, but with this unit, it’s a no-brainer. The price is good, the performance is fantastic, the overall design, build quality and aesthetics are all premium grade. With the added bonus of those gorgeous cables, as well as their LED block fittings, Super Flowers widely trusted hardware testing and competitive 5-year warranty the Leadex Platinum 550W ticks every box for what we look for in a great PSU.
