Silverstone Nightjar NJ450-SXL fan-less power-supply arrives

[HEXUS]

First seen at Computex 2017, this passive SFX-L 80 PLUS Platinum PSU has just been launched.

I'm not sure about that one, the way it has no ventilation means it's relying on external air flow to cool, but SFX tend to go into small cases which often don't have great air flow.

Agreed, I would be interested in seeing this put into a Mini-ITX NAS build within a small hot swap caddy chassis. Because the fact it's fanless and has a high efficiency is really interesting me.

I don't have any firsthand experience with SFX but if they rate it for 40°C wouldn't that sort of constant temperature inside a case be of a concern for other components also, in other words wouldn't you be try to avoid such a high temperature?

Most computer component tolerances allow and account for up 65 degrees persistent temp for long periods and server hardware is generally designed to run hotter for longer.

Still, if the PSU itself is working at 40C internally, then is it expelling air warmer than that? And wouldn't it be expelling it into the case and across the other components instead of out of the back? Meaning far less efficiency overall for the rest of the cooling? It all seems a bit dangerous to me having a passively cooled PSU.

It's only a ~55W heater at full chat, which isn't much compared to all the kit you can hang off it (i.e. 450W at max). If you've got enough airflow for all that then the PSU shouldn't be an issue

I'd love to have this , but with silverstone , Small = expensive, fully modular = expensive fanless = expensive , so adding all those together nets a price around 120GBP. Altho a lot of there other fPSU's are fanless up to 45-50c so this is just a more sealed, and aluminated version.
Platinum card only ... Lower your prices , or Kolink, gamemax will eat your lunch.
