Seasonic X-Series 650W KM3 Power Supply Review

Review Score:
55 Flares 55 Flares ×

Seasonic really need no introduction, they have been releasing multiple series of class leading power supplies in 2012. They recently launched the latest X-Series KM3 range, superseding the award winning KM2 units which we reviewed last year. Today we are looking at the X-Series KM3 650W power supply, a very popular wattage capacity with the enthusiast audience.

The X-Series 650W KM3 is not just a simple refresh however as the internal design has been changed and we will take a look at this later in the review. The KM2 was already a very impressive unit, so we are interested to see just how far further the company can push the new design.

They have three models already in the KM3 range, a 650W, 750W and 850W model all with a single +12V rail, fan controller and new modular cabling.

    My only problem with Seasonic is the pricing, they may be great, but I can’t afford the products of theirs I want to buy, I have to get cheaper.

    I have their last 650W PSU and I am happy with it. I always thought ribbon cabling was worse than the fat sleeved cabling, but I was clearly wrong.

    Just ordered one as I needed a new 650w, my thermaltake 750w died and it was noisy too.

    THanks for review

    Bah! Newegg dont list these as KM2 or KM3, what a mess. they needed to change the name to R2 or something so retailers would list them properly. they are all falling under the X series name, which is a mess.
