No 6 pin connector

Looks like I screwed up again - my ignorance knows no bounds!

I bought a power supply which I assumed to be good; my limited knowledge extends as far as knowing that the 12v rail is important, and it has a triple 12v with 18A on each. My current power supply has a single at 25v.

Came in the post today, tried to plug it in and lo and behold - I realise that the graphics card I bought (and was running fine with my previous PSU) a few weeks ago requires a 6 pin connector.

Which my new PSU doesn't have. And my previous PSU does - being around a year and a half old and only 450w, I had assumed that this new one would far surpass it in every way.

So, have I majorly screwed up and bought a 650w piece of junk? A 650w power supply that can never power an independent graphics card?

Any news (even bad) appreciated!
 
Thought about that, but my PSU has only one 12v 4pin molex anyway, from what it says on the box, and I'm assuming that's used for something else?

(I honestly have no idea about how it all works - my knowledge is rudimentary at best)
 
so i assume this is what is on your card

and since your new PSU doesn't have 6 pin plugs, you'll need a couple of these guys, molex -> 6 pin adapters:

Aha, I see - just picked up my GFX card box and have found one of those adaptors.

Alright, on my power supply it only has two of those 4 pin thingys - so by plugging them both into the connector to power the graphics card, surely that's not feasible? Doesn't some other component in there need them?

by four pin do you mean molex?

and yes it should work just fine, if you mean using 2 molex to 6 pin adapters. or does the 250 have only one 6 pin plug?
 
Yeah, like the ones in the picture above - my new PSU only has two of those molex thingies, so they'd both be plugged into the adaptor.

I'm assuming they're not necessary to power any other components, then?

molex are used to power a number of things, case fans, LED's, etc. from pictures i see that the 250 GTS has only one 6 pin power connector. all you would need to do is run the one adapter from any molex and than run the adapter into the card. as you can see molex have both an plug and socket on them. so there really is no reason you would every run out of molex plugs.
 
Cheers for bearing with me.

Wow, plug and socket? So one of the molex plugs in that adaptor is an outward one which can then go on to power something else..? :S

well i shouldn't have said that, im not certain that your plugs are double sided. but the ones from my cases fans are. either way, there should be no shortage of molex.

look at the adapter, does it have a socket on one side and then a plug on the other. if so than yes, you can run another molex into it to power something else.
 
Looks exactly like the one in your pic - I assumed it took 2 molexs to power one 6 pin or something :p

yep generally it takes 2 molex plugs to power a 6 pin. although my psu has 6 pin cables on it, so i don't have to worry about that :P
 
Well, I'll figure it out tomorrow and report back if I'm still stuck.

Cheers for the help, incredibly quick and useful as always!

Much appreciated!
