Connection question This psu has an extra connection I've not seen before. There is a blue and black pair terminating in a three pin socket (one pin unused). Can anybody tell me it's function and where to connect it ?

Never seen 220 on an auto!

You can still use this power supply but you will need to purchase a 4 to 8 pin connector . you can find them on ebay etc. You can also use two power supplies, one for gfx card one for PC. I use two. To turn on a PSU without it connected to PC ( just to use it as extra power.) You just have to connect the green wire to any black wire with a wire or paper clip. (At your own risk. Set pins first tape off and turn on by plugging into wall) . Good luck.

buy a 12 volt lamp tester (like a screw driver)check the wires when car ignition switch is turned on ,connect the wire side of tester to metal ground of ur car which supposed to be negative and other side of tested pin to the wires jack of ur car which is for radio connection previously,find out 2 connection points which are positive terminals one lights when igni switch is turned on the other one is permanent power terminal.now there are three wires of ur new radio one is black which should be connected to ground or metal body of ur car negative terminla and yellow connected to permanet power terminal and red one should be connected to power turned on with the swith which is called switched power
.now try to find out other four groups of terminal two for front speaker two for rear speaker each speaker has two wires ,can find out the connections by connecting a dry battery cell to the wires to identify which wires of speakers sound when battery is connected ,front pair of wires is for front left grey pair is for right front green pair of wires of ur new stereo is for left rear speaker and purple or blue pair is for right rear speaker
.these colors are globally known .the wires of speakers must not mixed with each other
black is for ground negative red is witched power and yellow for permanent power.
donot use long screws to fit ur new radio .Best of luck

The Prestige 1250EXT PS2E has a white or red(depending on how old it is) 4 hole rectangular socket on the back bottom left of the UPS when it is lying flat on the bench. The left end terminal is positive and the right end terminal is negative. This female socket(connector) is where the male battery connector from a Prestige battery pack will fit. It can only be connected one way. The DC battery bus is 60 volts nominal.

3-pair version of (red/green, black/yellow, white/blue). But the first two pairs are not twisted
So it becomes green/red, yellow/black, & white-black/blue. G1/ R2 /3Y /4B /5*Blk/6Blue (this is what you physically see on the other RJ11 connections since this is a data connection and not a phone connection it should be a straight-through instead of cross-over connection.
These RJ 11 PINOUT assignments may be incorrect because they apply to a color camera instead of B/W

1 SPEAKER (+)
2 VIDEO_OUT
3 GND
4 SPEAKER (-)
5 AUDIO_OUT/ALARM_OUT
6 12V DC

RJ11-e starts off like a RJ45 Stranded Patch Cable.
The color code used in stranded patch cables is different from solid-conductor cables. For NorTel Digital Patch Cable (DPC), the coding is; Pair 1: Green & RedPair 2: Yellow & BlackPair 3: Blue & *Orange White\Black
*In Pair 3 the color coding is Blue & Black instead of Blue & Orange and the pair is twisted so that the Blue wire is the 6th pin instead of the 5th pin.

There should also be a brand - the nVidia just relates to the chipset that the board uses, but its OK, lets check the wiring first.  If we still have trouble I'll get you to double check for the brand name.
Lets just check that you have the following plugs in place:

1. The 24 pin plug from the PSU (blue) to your motherboard - this powers the board itself.
2. A 4 pin 12v P4 connector plugs into the motherboard (near the CPU).  This is the CPU power.  It runs from the 8pin blue socket on the PSU.  Make sure that the end plugging into the motherboard is only 4 pin.
3. No power cables required to run the 8600GT so the red sockets on the PSU are empty.
4. Power cables going to all your peripherals (hard drives and CDroms).  These run from the black sockets on the PSU.

Does your current setup match that?

The wire that is white or most white and blue goes to green and the blue/white goes to red

Okay
guys: book says:
PIN 1 (red) 10-40 volts DC
PIN 2 (black) Ground
PIN 3 (blue) NMEA out Shows this goes to Autopilot/NMEA devise and to RXD positive RXD negative goes to ground (black)
PIN 4 (brown) NMEA in Goes to GBR 21 Beacon Receiver to a blue wire, brown wire on thaat devise goes to PIN 3 and the negative goes to ground
PIN 5 (white) no connection
PIN 6 (Green) no connection
PIN 7 (yellow) goes to alarm low Shows going to negative terminal on alarm relay and positive terminal goes to PIN 1 (red)

All Greek to me, have fun
