SX1000R uses the same rigid ribbon stule cables as SX1000. These are fairly common place with power supplies.

The individual cables can be split/separated from each other, then cable tied, which makes them little easier to manage.


SX1000R is semi-passive upto 250W and remains around 20~25(dbA), with 970RPM fan speed under 700W load. The fan becomes progressively louder between 700~1000W. The fan noise is noticable, but not overly loud. There is also noticable fan motor noise coming from the dual ball bearing fan.

The SX1000R features the same protruding connector ports as the original SX1000, first released in 2020. The protruding connector ports increases the overall length of SX1000R by roughly 5mm.

SilverStone opted to include 2x dual 6+2-PIN PCIe cables and 2x 8-PIN EPS. Ideally 3x single 6+2-PIN PCIe cables + 1x 8-PIN EPS should be be included for those with non-12VHPWR graphics cards.

There have only been minor changes from SX1000 v1.1, making the SX1000R more or less, just a 12VHPWR refresh. We feel SilverStone tried to cover too many base’s with its choise of included cables vs. catering to the target audience. This may be need and not have approach.
