Anyone have any current thoughts on a good quality power supply for a home server please?
Budget is somewhere around £100, but flexible for the right unit.

I've currently got either a 420w or a 400w Seasonic of ~10 years vintage in there (It's upside down, and I'm not pulling it just to check which :P ), which has absolutely nothing wrong with it, other than a lack of available power connectors.

As I'm upgrading the board, and have needed more drive connectors for a while, this seems a good time to upgrade the PSU whilst I'm at it.

Needs:
8 SATA connectors
4 molex minimum (These are used to power 5.25 SATA docks)
8-pin CPU power connector
Preferably modular
Silence would be nice, but not essential

Anything else can be daisy-chained off splitters.

Is there a current preferred unit for servers?
Very drawn back to Seasonic (I've got 4 of these in various boxes, all survived about 10 odd years with no hastle whatsoever), but quality is required.
 
That old PSU has anyway such low by today's standards efficiency that already that would eventually make some difference assuming server is powered 24/7.
HDDs don't draw much power per drive so using some splitters isn't that critical.

Seasonic Focus plus is very high performing PSU with even competitive pricing.
(component layout was likely chosen also for easy manaufacturing)

You can actually get 80+ Platinum model under £100

400W fanless Platinum unit goes over and comes with "only" 7 year warranty.

Bigger number of SATA connectors is limited to higher powered models in pretty much all PSUs.

That nothing can need 5.25" bays case fad no doubt doesn't help in PSUs having good number of drive power connectors.
