250W Seasonic SSP-250SUB FLEX SUB PSU, 80PLUS Bronze, Fully Modular, Dual Rail, 12A, +12V, 1U is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Not modular at all I was doubtful amount the modular nature of the PSU from the photos so checked the Seasonic website, which also claimed that it was "fully modular". There is nothing modular about the cabling. There is a single block, which all of the cables are attached to, which attaches to the PSU. You cannot remove unwanted cables, you either connect all of them or none of them - which makes the "modular" aspect completely redundant and overly complicated. As for the PSU itself - it's replacing an old HP microserver PSU which died after 8 years of 24/7 service. I'm sure it will work just as well, Seasonic make great power supplies. If you're also replacing an old microserver PSU check the connectors that you need. I had to modify mine with extra molex connectors which instantly voided the warranty.

Which cables are supplied with this PSU

Which connectors are on the cables supplied for this PSU? What is the length of the PSU? Thanks
Asked by: Dedge
The cables are all connected to a single block, which makes it very "unmodular" - just for clarity. From memory (installed a few hours ago) The connectors are: 1x Molex 12v 4+4 pin 24 pin 3x SATA 1x Floppy (4 pin)
