Power supply connectors:
The power supply in my Son's PC was squeeling (I'm sure it was "electronic", not the fan) so I decided to replace it. Went from 400W to 650W at the same time.
Got it in, and everything works - he's even stopped getting weird interference noises in his headphones, so very happy.
But one thing I noted:
His video card has a 3x2 socket (similar in style to the 4x2 CPU socket) that had an adaptor going to two old style Molex connectors, which connected to two Molex plugs on his old supply.
The new supply seems more modern, and had a couple of "PCI-e" connectors, that the old supply didn't have, in a 3-or-4x2 arrangement. That is, a 3x2 with another 1x2 next to it, so it can be used in a 3x2 or 4x2 socket.
It seemed possible these were for cards like his (it is in a PCI-e slot ...) so I tried to connect, but it seemed to not want to connect (I had it the right way around), so instead I just used the 2-way Molex adaptor again. The new supply still had 3 Molex so that was fine.
When I looked again at the adaptor, it turned out one of the pins was missing (as in, possibly a "key"), and this wasn't "missing" on the connectors on the new supply, so maybe that's a sign they weren't meant to be used there. (I couldn't look at the socket on the video card without pulling it out).
Anyway, anyone got wise words on what that's all about? Should I have just pushed harder on the plug? Or is this length-of-string stuff that's too vague to have any comment on?
Cheers,
(Edit: picture of what I'm talking about here. Except the plug on far right in pic has socket missing in middle of one row http://www.playtool.com/pages/psucon...tml#pciexpress ) .
