Epilogue
The SilverStone Extreme 1000Rz is a high-performance SFX unit, which, with a tighter load regulation at 12V and better transient response on the same rail, under normal loads, could be closer in overall performance to the top-notch Corsair SF1000. That said, Silverstone’s new offering scores second in my overall performance graphs, and if I had an MSRP, I could also comment on its performance per price ratio. Meanwhile, the SF1000 costs $240, which is a hefty price, but in PSUs, the higher the power density, the higher the price.
The PSU’s build quality is good, with Japanese caps on both the primary and secondary sides and Infineon and Toshiba FETs, and the FDB fan doesn’t have to spin at high temperatures, since a large enough heatsink also cools the 12V FETs. The Extreme 1000Rz achieves silent operation at light and moderate loads, being notably quieter than the SF1000 in average noise output.
All in all, be quiet! The SilverStone Extreme 1000Rz is designed for users seeking a powerful SFX unit that remains quiet under both light and moderate loads. At the time of the review, there was no price information available; however, it’s worth noting that high-end SFX units are not affordable. SilverStone should keep its price close to 200 dollars to avoid a direct conflict with the top-performing Corsair SF1000.
Before investing in a new power supply, read my Best ATX v3.x PSUs article to check all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the price of the product. I receive a commission from Amazon every time you do it, which can make a significant difference for me, especially now that I am working independently, exclusively for my media, rather than for someone else.
