Review SilverStone SX1000 SFX-L Power Supply Review


Why would anyone need 1000 watts in small itx case ? it will only take one GPU anyways and no one needs 1000 watts for that.

If you want to stay around 50% load for max efficiency then this needed. Especially when people cram like a 3090 and a 5950x/ into an ITX with custom water cooling and stuff just because they can. Alternatively they might be a modder where they need the smaller PSU for some reason. Definitely a niche product though.


I have the 700w version of this in a Fractal Design ITX case. It does not ship with the bracket necessary to mount to an ATX PSU location. Just sharing for others to be aware of.

Nearly silent PSU, by the way.
