  1. I have HP Pavilion a6200 (GN556AAR#ABA), The power supply seems to be dead.
    Power supply model # ATX-250-12Z rev D6r. I was trying to buy the same unite, however I can not find it. All what I found is ATX-250-12Z rev D7r.

    I would be very thankful if someone can confirm, that I could get rev D7r to replace D6r. Thank you and Happy Holiday!

    Whatever you do don't buy another Bestec they are absolute garbage. Here's a review of a model similar to the one you have:

    Your PSU is standard ATX so any standard size PSU should fit.
    I would recommend one of these:

    SeaSonic SS-350ET Bronze 350W = $43

    Antec NEO ECO 400C = $45

    PC Power and Cooling Silencer MK III PPCMK3S400 400W = $70 ($50 after rebate)

    These are all much better than your current PSU and give you some head room wattage wise for future upgrades such as a video card.

    Here's a review on the 600w version of the PCP&C

    I only recommended the PCP&C Silencer MK III PPCMK3S400 because there is a rebate on it. Don't get me wrong it is a great PSU but the Antec NEO ECO 400C is built on the same SeaSonic platform and is generally much cheaper, however the PCP&C has better capacitors so if they are around the same price I'd go with the PCP&C.

    Measure the current but failed power supply for height, length, and width, then make sure what connector plugs and sockets you need... then buy what you can best afford that fits.

    You don't need a high end unit... But it must fit the case.

    Sites such as have hundreds of different power supplies that will provide you with an affordable choice for that unit. It doesn't need anything fancy. I recommend FSP group units for those kind of jobs. They last forever and do the job.
