The Dagger Pro SFX has exceptional specifications for a small PSU. A strong single +12V rail is the best choice for new computers and high-end graphics cards. The +12V rail is rated at 850W itself. Since the PSU is a high-efficiency unit, we expect it will handle a top-of-the-line gaming PC, the same as large ATX units.

The efficiency is about as high as presented by FSP. Even if we are not going to use 800W+, these higher wattage units seem like a good idea to keep optimal voltages, low temperature, and low noise.
Compared to the previously reviewed Dagger Pro 850W review, the refreshed version has an improved fan curve. The fan still starts spinning at about 20% load, but it makes less noise at a higher load. Until about 350W, it’s hard to hear it, and it’s about a typical gaming PC load.
