At this point, I couldn’t even count how many SFX power supplies that have come into the office. I love the form factor, even when building in smaller cases that can fit a full ATX power supply. Early on the SFX form factor was limited in power and because of the overall density struggled with heat and with that noise. That has improved a lot over the years, especially with Silverstone being a champion for SFX all the way from the start. They used to be the only option available if you wanted an SFX power supply with modular cables. Recently they introduced a few new SFX power supplies and one really stood out. This time it wasn’t about the jump in wattage, this model, in fact, has the same 450-watt rating of the early Silverstone SFX PSUs. The NJ450-SXL stands out for two reasons, it is 80 Plus Platinum rated which is great and also because it has no fan at all. The noise issues of the past can’t be an issue if there isn’t a fan to make noise right? Well, today I’m going to check it out and while we don’t do full PSU testing I am going to take a look at the thermals of the NJ450-SXL while under load to see how it does for cooling with no fan.
