When I first received the Fractal unit, I figured it would be a stout little unit for running a single card setup, which gets a little toasty. I am happy to report that the SFX unit stood up to the literal abuse and walked away with a win in this case. It never faltered during any of our testing or caused a single workload error. I want to take this moment to remind readers that if you plan to run a heavily loaded workstation rig, which will be pounded by a constant loading with multiple cards. Please get a more suitable PSU as I subject these units to this level of testing to see how stout they can be when pushed beyond what people should use them for.
What did we like about the ION SFX 650G from Fractal Design? Well, let's start with the fact that the unit performed with beastly stability during a workload that, in my mind, I would have been ok with if it eventually thermally tripped. The ION SFX 650G ramped up and stood its ground, and in my mind, that's admirable. The flexible cables with the Fractal unit are a welcomed addition as SFF PC's need as much malleability as possible. The larger fan did an excellent job of keeping the unit running when I put it under the hammer of our test rig.
Now for things, I do not like, and I'm not sure there's going to be a lot here. The unit is 650W, so we have to temper our expectations accordingly. If I was to be very knit picky, I could mention that the cable set is short. And I did not see a longer cable kit available. The inclusion of the ATX adapter means some users may buy it to fit in, even an mATX tower. Where it may not have enough length to reach, but that's a minor thing as I have not confirmed this. This is all I could come up with at this time. The ION SFX 650G works as expected and goes beyond the level of loading all, but the most insane will put on it.
The price, at $109.99 it is a clear win for Fractal as this price range is where most 500W units reside.
Fractal took a robust design and priced it in such a way that SFF users would be hard-pressed not to pick it if they need the grunt this unit can supply.
