I would like to see higher PF readings in general.

The 5VSB rail’s efficiency is high.

  1. Hi Aris,
    I had a general question about PSUs and don’t know where to post it so I’ll just put it here.
    For most of the other PC components there is this “world of information” that you can use to make decisions on what to buy but also when to buy. Either news, announcements, rumors, roadmaps etc , but for PSUs it’s mostly silent, especially for non flashy brands.

    I’m looking for a new PSU 1000-1200W. I bought the Leadex II a long time ago, by sheer chance with no research and it turned out really good and was looking to keep consistent. I can’t find the 1200W XP version around, only the 1000W XP or Gold but they both seem just decent from the reviews and not top of the line like the 1200W version.
    Also can’t find anywhere near the FSP Hydro Ti Pro. All the shops I called said they have stocks when a new unit comes out and slowly go out, and it’s the same thing for most of the top line units. Mid range units are in stock everywhere.
    I feel like I’m chasing blind.

    So how often do manufacturers launch new lines? It is wise to just buy whatever you find available at a given time or is it worth waiting? How do you know what is expected to come? Could a new ATX spec significantly change the scene?

    Thank you!
