The Corsair SF850L currently is the best SFX-L unit that you can find in today’s market. It isn’t the quietest though, but you can read more about this in the full review! Lastly, it offers ATX v3.0 and PCIe 5.o compatibility which make it future-proof.
I have already reviewed the SF1000L, which left an excellent impression on me, so it is time to look at the SF850L. The same OEM, Great Wall, makes both units, so they share the same platform. They are compatible with ATX v3.0 and PCIe 5.0 and feature 12VHPWR connectors set at 600W. Typically the 12VHPWR connectors should be set at 450W and 300W for the SF1000L and SF850L, respectively, but most brands ignore this Intel guideline and proceed with a full-power 12VHPWR cable/connector. This is because some users complain that their cards cannot get full power, although the performance difference between a 450W RTX4090 and a 600W one doesn’t justify the increased power consumption.
With a price of $200, the SF1000L is way more affordable than competing offerings from Asus, Thermaltake, and Silverstone, and the same goes for the SF850L, which has a street price of $180. The only SFX unit with 850W max power and alleged ATX v3.0 and PCIe 5.0 compatibility with a notably lower price is the ARESGAME 850W SFX model, which costs $130! Given that I evaluated a PSU of this brand in the past for another media and the horrible results, I can safely assume that performance will be bottom low and the unit ARESGAME PSU won’t be able to meet the strict transient response tests. I will try to find a pair of these units for testing to ensure I can finish all tests once the first breaks on the test bench.
