The SilverStone Extreme 1000Rz is Platinum certified in the Cybenetics efficiency scale and it meets the Intel SFX12V V4.1 specification standard which is the equivalent to the ATX v3.1 standard but for SFX units.
The SilverStone Extreme 1000Rz is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
The SilverStone Extreme 1000Rz is an SFX unit, meaning that it has notably smaller dimensions than a standard ATX PSU and a higher power density. The same PSU has a 92mm fan, which is ideal for this form factor since it allows for a higher airflow at lower speeds, compared to an 80mm fan. Regardless of the PSU’s footprint, it is always nice to manage to keep the noise output as low as possible. The issue with such high-power-density units is that there is not enough space among parts on their small PCBs to allow for optimal airflow, so their small fans have to operate at higher speeds to provide the necessary airflow and static pressure required.
