My 300W PSU on my 4-year old PC has died. It was underpowered anyway
(after adding extra HDs and a DVD drive) so I'm about to order a 400W
replacement. My problem is that I'm not really clear about the
specifications for the cable connectors. I see all sorts of
descriptions on various web pages:
5.25" Device Power Connectors
3.5" Device Power Connectors
Molex connectors
SATA connectors



"20-pin adapter for ATX version 1."
5.25" Device Power Connectors : 4 + 2 SATA
3.5" Device Power Connectors : 2

Antec SmartPower 2.0 SP-450P 450W Active PFC PSU
------------------------------------------------
"24-pin power connector with detachable 4-pin section for backwards
compatibility with ATX 20-pin motherboards."
5.25" Device Power Connectors : 4 SATA
3.5" Device Power Connectors :

My dead unit has 5 connectors each containing 4 round sockets about
2.5mm in diameter. They were powering my 3 hard drives, my CD drive,
and my DVD drive. (A pair of wires also went from one of these to the
rear fan.) Are these 3.5" connectors? Or are they what I see described
elsewhere as 'Molex connectors'?

My unit also has several other connectors, of which the only one being
used was a small 4-hole one, a bit like a phone socket connector, used
for the floppy. Is that what is described above as a 5.25" connector?

My unit also has a few connectors that were not being used: a little
4-hole one (2 rows of 2) which I *think* is described on some sites as
needed for certain motherboards? And one with 6 rectangular holes. And
a spare one like the one used for the floppy.

I don't suppose anyone knows of a page showing labeled pictures of all
these please?
