Endorfy Vero L6 PSUs: ATX 3.1 also in cheaper, lower end

News, PSUs | | Ľubomír Samák

Although even the Supremo series PSUs were not expensive, it is the new Vero (L6) series that truly fulfills the Endorfy philosophy of affordability. These PSUs also feature the 16-pin 12V-2×6 connector and support the latest power standard (ATX 3.1), while being relatively inexpensive. This is partly due to a relatively lower efficiency, fixed cabling, and a simpler fan—but that’s the point. Overall, these PSUs look promising.

Seasonic is also taking its fan development seriously, boosting efficiency in part by increasing thickness – to a non-standard 30 mm.

Graphics, News, PSUs | | Jan Olšan

Last weekend, we focused on the issue of 12VHPWR and 12V-2×6 connectors on Nvidia graphics cards, particularly what Der8auer’s findings revealed about their reliability and safety. Beyond the problems with cards like the GeForce RTX 4090 and 5090, this issue has another manifestation: while Nvidia claims the problem no longer exists, other hardware manufacturers have started coming up with their own ideas to address or prevent it.

This is what we will focus on in the measurements with “80 Plus” PSUs, one of which is also already quite old. Read more “Minitest: Cheap PSUs vs. graphics cards coils whine” »
