    Powering this MoBo, will the OPUS do it?

    I was wondering if my OPUS 320 will power this thing.

    http://www.newegg.com/Product/Produc...82E16813130255


    I notice that the connector on the mobo for the power has 24 slots. The Opus 320 only has 20 slots/pins. Will it still work? What exactly is the extra connector for?

    i found a good link about the subject for you, http://www.smps.us/20-to-24pin-atx.html the only thing i can think of that might also be a problem is the 4 pin molex connector near cpu for the extra power the cpu needs hope this helps SNO

    My new asus mobo requires the 24-pin atx as well. The opus 360W I have includes two four-pin connectors, one that slides into position along side the 20-pin one to form the 24-pins (there are two little notches on the side of it to help line it up), and the other that connects to the other 4-pin molex.

    I'd be a little suprised (although not too suprised) if your 320 didn't come with both of these connectors.

    Edit:
    The 250W,320W and 360W user guides all point to the same 250W user document here (Image J9). This seems to indicate that it does have a 24-pin connector. You should have the 20-pin, so just line it up with the 4-pin one I mentioned above.

    As far as the connectors, that is an easy remedy if the Opus doesn't have them. There are adapters to physically connect everything if the PSU doesn't include them.

    And as far as supplying power, the CPU is the biggest determiner of power draw, not the motherboard.
    You know that, HiJack.
    Have you looked in the FAQ yet?
    How about the Wiki?



    Under normal circumstances, a signature would go here.

    I think I recall the OPUS 320 having the CPU Molex connector, but I dont remember it having the extra connector that slides in next to the 20 pin connector. I dont know because I modded my OPUS. I think I am going to have to order a new cable from them.

    The OPUS 320 didnt come with them. The picture in the instructions shows a 24 pin, but thats the part that connects to the OPUS itself, not the part that connects to the MoBo.

    You know that, HiJack.
    Yea I know...... A Core2Duo uses about 65W..... Thing is the manual says that it require 350 watts power. I also want to add 2 PCI graphic cards, 3 USB hubs (which are powered externaly by another device) and the USB to VGA (which has a tiny power draw). I cant seem to find the wattages that the 2 graphic cards use, but I do not think much, since they are old school.

    If anything, I could always update the card to the OPUS 360, but Im scared that even that is not enough. Do you think the 350watt rating is just a random number they throw out?

    there is always a point to why they want certain hardware, but there is other factors, or equipment that they might have assumed the end-user would have that you will not..

    also, keep in mind that 350watt ac-dc power supplies are some of the most common, cheaper power supplies out there, so this could have also been part of the concept of the recommendation..

    it looks like those graphics cards are bus powered-- i don't see any sort of power connections on them.. so you could try to determine the max allowable draw from a pci port, and then use that as a rough estimate..

    Thats a great idea..... I guess what I can do is build the system and try to power it with the OPUS. If I cant then I know we will need more power.
