  • 24pin atx on m/b with only 20pin psu

    hi all

    i just bought a asus a8n5x for my second pc. On the motherboard it has a 24pin atx connector and my powersupply (450W) only has 20 pins on it. It fits in leaving a 5v-12v and 2 grounds empty. I wasnt game to start it up like this, so i was just wondering if someone could tell me whether i need to buy an adapter or get another PSU for it to suit 24pins... Its not SLI and only has a amd 64 3200+ in it with a 512mb 6800gs video.

    Any help on this would be great. It may sound like a bit of a nub question but i have been out of the pc scene for around 14months and im out of date.

    Having a 20-pin PSU greatly contributes to instability, and unless it's a good brand it won't be enough anyway. I'd suggest you be a 450-500W from a really good brand that has a native 24-pin (which can be 20-pin with a detachable 4-pin, and most are) connector. An adapter can help a little, though in some cases it can actually be bad for the
    PSU and/or the motherboard.
