    replacing power supply

    My ancient Dell XPS 410 has a 375 watt PS which I need to replace. My very 1st time replacing PS. Are all PS's of a standard size or do I need to take measurements of my old PS?

    Thanks to CompUSA closing all their local stores, best buy is the only place that has power supplies. Any suggestions/recommendations for buying from them? Am looking at the Thermaltake 800W PS.

    The larger the wattage rating, the physically larger the PS. I would measure the area you have available and go from there. 375 watt is a very small rating by today's standards. Also look at the mounting of the PS. Take the old PS with you when you purchase a new PS. Any PC maker will have PS in stock as well. There should be repair shops around as well.

    Yeah, it should definately fit inside the case, so do take measurements.
    I couldn't find your current PSU's measurements, so measure it to ensure it's replacement will physically fit where
    it it supposed to.

    This should be of some help:
    Dell™ XPS™ 410 Service Manual Removing and Installing Parts

    You might also have a look into this thread from the Dell forum and see how closely it correlates to your own situation.

    Whatever you choose for a Power Supply, go for something that is as modular as you can get.

    Newegg and or Tiger Direct are good places to shop for computer components.
    If you have a Frys in your area, they usually have a decent selection.


    Major Points to consider:
    1. Must fit in the space where your old PSU was.
    2. Note the pin size on your motherboard: 20+4 vs full 24. (your current one should be full 24 pin)
    3. Cable management: get as modular as possible to better manage cables.
    If your system is small you'll need to consider airflow.
    4. ATX vs MicroATX (your current one should be ATX)

    If that XPS 410 is the big tower, with the access panel on the right side, I've already replaced the PSU in one of those. And yes, it was a standard size. I put in an Antec Earthwatts 650 that I bought at a local Computer store.

    Dell should be jailed for ever putting a 375 watt PSU in a big computer like that. OH Yes, , , that 375w, if you read the label carefully, is the Maximum surge wattage that the supply is capable of putting out.... for the brief time it takes to charge the capacitors on the motherboard and start the fans and drive motors.

    De-rate that wattage by as much as 30% for the all-day operating power.
    Dell was never known for putting any more of anything in their PC's than was needed to get them out the door. Sorry about that!

    CompUSA went bankrupt, but Tiger Direct bought them out, , , lock, stock and name.
    The CompUSA store in Altamonte Springs, FL, is still open for business, but run by Tiger Direct. I shop there often.

    Good Luck!

    When it comes to PC power supplies, I take a saying from the Monster Truck guys......."Go Big, or Go Home!"

    EDIT: I just Googled "Dell XPS 410" and found tons of information.

    600W may be slight overkill but it'll run cool and efficiently in your PC.

    The PSU you linked to doesn't have a good reputation - cross-referenced with verified owners comments on Newegg, it has 38% of responders giving it 1-3* = not good. For a few dollars more ... this looks a better buy, only 12% 1-3* rating.

    Check your local stores to see what's available locally then spend an hour or 2 researching before committing your cash.

    Cool

    I have experience with those XPS 400 series PC's. After all, I'm in the PC repair business.
    They are power hungry, so a 600w PSU (truly, maybe 400 to 500w) is not overkill.

    Good Luck,
