I have a 500w psu and It dosen't have a 6-pin or even and 8-pin, so I'd like someone too recommend me the best gpu without needing a 6-pin or 8-pin. I don't want too upgrade my psu and I don't really know why it dosen't have a 6-pin if it's 500w, I bought a gtx 750ti for christmas and I used it for about an hour then I got no signal on my monitor so I took it too a computer shop and the man said it was 'dead' because I think it used up too much power or something i'm not really sure. Because I have no 6-pin I had to get a molex to 6-pin and I think that's using alot of my psu power (im not good with hardware so i don't know). I've looked everywhere in my local stores for gpus without a 6 or 8-pin but there is none (stores like currys, argos and maplin) I just can't find any somebody please help me...
