    model:dps-400lbb is for the Sony Vaio Desktop computer and it has 20 pins. Several issues with the particluar power supply. internally there's nothing special about it except it's odd dimensions, it's 140 mm (5.5 inches) by 160 mm (6 inches). A regular ATX power supply is the reverse, 160 mm by 140 mm or more. If you get a standard ATX power supply. It's too
    wide. You're going to hit the graphics card.

    Another problem lays with the bolts stick out of its housing. There's a latch to lock the bolts in to place.

    If you don't know what you're doing, don't do this. You'll probably get shocked or ruin a brand new power supply. I'm just thinking out loud for possible solutions. I guess you could gut out a new power supply and just exchange the housing, but there's only one problem. Delta Electronics do not make these power supply any more. So, finding a perfect fit is rather difficult. If, you can find these rare power supplies it ranges any where between $130 to over $300 for the same or comparable part. You're going to spend that kind of money for a weak 264.7 watts. Are they crazy?

    Well, if you know what you're doing? Remove the fan inside the power supply and savage the fan. You can open the power supply by removing the standard 4 screws and wedging a flathead screw driver at these small opening and turn. work slowly and evenly around the case. Once you get it loose, side it out gently. Be careful not to crimp or tear out any wires.
    Oh back to the fan? If you remove the top of the case there's an identical fan cooling the chambers for the CPU.

    I don't know? I think you're better off purchasing a full tower that takes a standard ATX power supply, add a heat sink and fan. You might give up some neat feature such as the cooling system for the CPU and some plugs-ins in the front of the case, but in the long run, repairs would be much simplier, parts would be readily available and probably much cheaper.
