So...will my new PSU work with the new LGA775 motherboards?

    So, I just recently bought a new Antec 480watt True Blue power supply - which has a 20-pin motherboard connector. Now my question is: The new P4 LGA775 motherboards now have a 24-pin connector, what are those new 4 extra pins for, and will I be able to still use my PSU on the new motherboards? :rolling:

    That doesn't really answer my question since many of the people in the forums said "yes", while many others said "no". :bang:

    Also, do I plug the 4-pin P4 power connector in to the extra 4 pins, or do I leave the P4 and the extra pins un-connected?

    Also, I found out that the 24-pin motherboard power connector is going to be the standard for the new motherboard standard (BTX), that'll replace the ATX standard over the nex several years. BTX motherboards use the 24-pin connector to do away with the seprate 4-pin P4 power connector...which is why I asked the question above. :rolling:

    Ok, seems the links above were a bit misleading. Thing is: There is no cenceptual problem that would prevent your rig from running with your PSU and your chosen board. You can either use an adapter that's available for conversion between 20 and 24 pins, or you can simply plug the power cable into your MB. The plug is coded, so there won't be any room for confusion.

    If your MB comes with an extra 4pin connector, then yes, you'd connect that one to your PSU as well.

    There may, as I'm aware from above links and other sources on the net, be an issue with stability due to lack of power. However, all posts expressing these concerns came from users who didn't use and hence didn't have any experience such a set-up. All users who actually run such a system gave positive feedback.

    And with your 480 W I find it highly unlikely that you couldn't feed your PCIe. May depend a bit on what other gear you have in your rig, though.

    Conclusion: as your set with your PSU (as it was just bought recently, and a good choice it was), what other choice do you have if you're aiming for high performance and a LGA775? If I was you, I'd give it a try. I'd feel quite secure as well.

    Ah, BTW, you can check, whether your PSU is labelled "ATX12V" or not. If it is (yep, the Antec 480 True Blue is), you're set for a new P4 system.
