I have an Antec 430W psu for sale, it's a TRUE power. I used this for about 3 months. - 30
I also have an Allied PSU, it's 500 W, it was used for maybe a week. 40
I was just gonna say, is there something new that i'm missing. There is a 6 pin connector, it's the old square one, as ZL1 said. I believe that's what your talking about.
Also, because I need room, you can have both of the PSU's for 35 bucks. If you pay for shipping of course.
