Seasonic was brave enough not only to design a PSU that easily stands out from the crowd but to mass-produce it, as well. This product is the first of its kind, and we hope that Seasonic will release more Connect models, covering a broad capacity range. 

With a chassis that has more than 20mm clearance behind the mainboard tray, the installation of the Connect PSU is straightforward, and the fact that you don't have to deal with long cables makes the cable routing and management processes trouble-free. Besides that, shorter cables can also lead to increased airflow, since they occupy less space into the chassis, so the block less the airflow.

Usually, new designs don't go along with high performance, but this is not the case with this product, which achieved a pretty high overall performance score. Moreover, it carries a fair price tag, given its features and the increased production cost, because of the Connect module. We also highly appreciated the fact that Seasonic took an extra step and made sure that there is an additional over-temperature protection circuit on the Connect module. 

This shows that the design is mature, and its engineers took everything into account, and they didn't rush in releasing this product into the market. Finally, the lack of active cooling in the Connect module doesn't pose a problem, since we highly pushed with the full load that the minor rails can handle, for a prolonged period, and it didn't sweat. Finally, the build quality is impeccable in both the power supply and the backplane.

The Seasonic Connect 750W currently costs about 20 dollars more than the Prime 750 Gold (SSR-750GD2), a price difference that looks low given that the package includes the Connect module. This is the first power supply of its kind, so there is no direct competition. Hopefully, we will see more PSUs of this type in the future, and it would be helpful as well, to work on making the connection between the power supply and the backplane modular without any significant efficiency losses.

    I was curious about this one. Not bad, but there's room for improvement.
  • Math Geek
    i missed this one some how before it was released. but i like the idea and do hope we get more and more of these. is a solution to something i never even thought of as a problem, but now can't imagine doing without!!
  • Myrmidonas
    An idea better than RGB in my opinion. Implementation can be improved though.

    Thanks for the thorough and comprehensive review, Aris!

    I don't have a problem with their existing modular setup. I have 3 Seasonic modular PSUs (and one semi-modular) and have swapped two of them between machines, on a couple occasions. It was very nice to be able to swap PSUs without having to unplug, reroute, and reconnect the cables from everything - just disconnect them at the PSU end. I also like being able to borrow cables that came with one PSU to use with another.

    With that said, I would use this style of setup under two conditions:
    Actual PSU performance should equal or exceed their conventional models.
    Cable compatibility should be retained with their existing modular PSUs.
    Otherwise, I'll just stick with what's been working just fine for me, as long as they continue to be available.
