Power Supply Problems

By AXXEL
Aug 17, 2006
  1. I just build a new computer and the power supply that i put in was smelling like it was burning and after some time the computer Turned Off so i figured that the power supply was dead (it was NEW!). i plugged in a different power supply to the MoBo and it worked the first time but when i plugged in the CD, HDD and Fans it never turned on again. So i moved the power supply back to the original computer and it didn't work, it seems like the new MoBo is burning up all the power supplies WHAT SHOULD I DO... THIS IS MY LAST CHANCE I HAVE OF MAKING THIS WORK PLEASE PLEASE HELP WHY IS IT DOING THIS!!!!!

    What is the brand /rateing (amps and watts) of these PSUs.It sounds like they are being overloaded.

    Also post the system specs.So we can better determine what type of PSU you should get.

    MoBo: ASUS P5WD2-E Premium
    RAM: Corsair XMS2 Pro Xtreme Performance TwinX Matched 2GB (2 x 1GB)

    GPU: X1900 XTX 512MB

    and the case has 5 fans to cool the the thing
    the Power Supply is a Logisys 550W

    those "500W","550" PSUs are both from cheap brands and are probably are over rated. Most cheep 500W PSUs actually only produce 200-300W under normal conditions.

    I recomend one of the following

    http://www.pcpowercooling.com/products/viewproduct.php?show=S61EPS

    The PC Power & Cooling ones are the best but also the most expensive. They are all verry Good PSUs. They all also have protection circuicts so If there is any kind of short they will not burn up or fry any other components.

    they look good but what is the difference between a power supply that is not SLI ready i dont have an SLI video card I have a Radeon X1900 XTX. Will the SLI power plugs work with my video card or will i have problems?

    Sli uses standard 6pin PCI express Power connectors so yes they will work. Sli ready PSUs have atleast 2 PCI express Power connectors and enough power to run two video cards.This usually means about double the amps of a standard PSU. You don't realy need an Sli/crossfire ready unit but that offers more room for future upgrades.

    The first one is on the list of bad PSUs the second one is ok but not recomended
    Here are some links to the lists

    refer to the brands in blue (not the blue underlined ones those are just adwords) on the last list for the PSUs that you should look for.

    It is made by Raidmax a bad brand that is known for poor reliabiltiy as well as overateing their PSUs (ie:630W PSu probably only produces 250-350W at room temp but can produce 630W at an extremly cold temp like -50C so they can give it a high rateing)Most flashey PSUs (ones with clear caseing,lighst)look good but preform poorly. Raidmax is on every list you can find of bad power supplies includeing the three I listed.

    well that sucks i just bought it a few days ago but i'll use it to see if the MoBo is actually killing the power supplies and if it dose i can always return it.
    unless you think that it could cause damage to other components.

    It does have overload and overvoltage protection so it won't fry anything.It is one of raidmax's high end models so it is probably made better than their cheeper models.It probably puts out about 450-500W at room temp which should be enough for your system but don't expect 630W unless you cool it with liquid nitrogen.After doing some reasearch it doesn't seem like as bad of a PSU as I initially thought but It is still probably overated by at least 100W and I don't trust the brand.

    That is a verry good PSU from one of the top 3 brands (Antec,Enermax,PC Power & Cooling) It is more power than you need but that leaves room for future upgrades. the most important item on any PSU is no the total wattage but the total combined amperage on the 12v rail(s) (at least 26A for modern video cards).
    Here are the full specs
    http://www.newegg.com/Product/Product.asp?Item=N82E16817103933
    It has a combined 38A across two 19A 12v rails which is more than enough. it is also sli certified. You will need an open drive bay if you wish to use the control pannel.
