The motherboard will only draw the wattage/current it needs.
Be carefull with Branded machines often their components are proprietary.
Remove the 20 or 24 pin connector to the motherbaord and compare the colour coding of the pin outs with the examples shown on this site.

Is a 500w power supply to much for my pc?


wattage is a measurement of power output. however wattage is not nececassrily a measure of continuous power output. wattage is a measurement of potential power output. this means on one hand if a pc is only idling the wattage of the power supply unit (psu) required to run the components might be very low. on the other hand if you have several power intensive applications running simultaneously with several different web browsers open featuring several active tabs open in each browser and you are also streaming video on the internet on one browser and downloading files while watching a movie all at the same time then the pc would probably be working near its maximum and would require near the maximum amount of available wattage from the psu. a certain amount of the psu's wattage is needed to power each of the key power consuming internal components - the cpu, the memory, the motherboard chipset and other motherboard devices, any expansion cards installed on the motherboard as well as the spinning of the hard drive, optical drive and cooling fans. the total wattage required to power all these and other internal components is an indications of the very bare total minimum power capacity that a pc will require. this means that generally the higher the wattage of the psu the more stable the overall performance of the computer islikely to be. the psu also consumes as well as delivers power due to the in-built cooling fans required to cool it by venting hot air from the back of the pc during operation. therefore as a general rule the higher the wattage of the psu, the greater the capacity of the psu to take the powering of all the internal components of the pc that require power (including the psu's own cooling fans) well within its stride.

so your friend was correct to draw your attention to the important issue of the optimisation of power consumption in a pc and ensuring that you have the correct wattage of psu to adequately and safely power the internal components of the pc. however your friend has slightly misunderstood how the psu works.

perhaps you could explain to this friend that a pc with an underpowered psu is far more likely to damage a pc's internal components than a pc with a psu of excessive wattage. In this way, both of you will have helped to enhance each other's knowledge and awareness of an important issue in the maintenance of a pc.

Presuming you mean the Earthwatts 500:
Should work, though the Earthwatts has the 24 pin ATX instead of the 20-pin.
http://www.atxpowersupplies.com/manuals/Antec-Earthwatts-EA-500D-user-manual.pdf
You just need to snap the 24-pin connector apart to make it work as a 20-pin. It can be snapped back together for future motherboards.
The Bestec is just a standard ATX power supply

Ptowreplaced power supply worked 2 days now well not power up aagain


It is possible that you might be overloading your power supply unit. Go to this website and calculate how many watts you need for your system. You just have to select the components in your system from the drop down menus and it will calculate your power requirement.
http://extreme.outervision.com/psucalculatorlite.jsp
After getting your power requirement (in Watts), replace your power supply with a unit rated at least the recommended PSU wattage. Also note that cheap power supplies usually do not reflect the true wattage output on their labels. Try to get a power supply unit from reputable PSU manufacturers like Antec, Coolermaster, Thermaltake or Corsair.

The fan turns on and off for the SL350


you might have a faulty PSU power supply unit or a faulty power point or lead
test the power point first by trying another electrical device then test the lead if these fail you will have to test the PSU using a multimeter making sure your psu is getting the correct amount of voltage and wattage
hope this helps

I agree with you about the power supply being faulty. Unfortunately FixYa is not affiliated with Antec nor sells or service any computer components.
You need to contact the supplier who sold you the power supply or contact Antec.

How do I wire up my Asus p4p800 se motheboard with an OCZ ModXtreme 500watt Po PSU. My old psu was an Antec 380Watt


no need to modify anything just plug in the 20 pin mb power connector the 4 pin cpu connector and your HDD's and disc drives power the same as your old setup and your good to go. mb's are designed to handle a broad range of wattages, if your not sure what plugs go where take a few photos before you begin unplugging or draw a simple diagram

N15232 motherboard wattage help


the power supply wattage rating is MAX wattage, not constant wattage. the power supply only outputs the amount of power that the rest of the computer calls for, and no more. if yor computer only needs 200 watts, that is all that will be sent from the power supply; even if it has a max rating of 600 watts, it will only send the amount of watts which your computer calls for.

Optical drives gone after replacing power supply unit


I suspect something was not plugged in correctly. Double check all the IDE cables and power cords, make sure that the slave drive and master drive are set correctly. This is determined by a set of jumpers on the end of the drives. The one set to master should be at the end of the IDE cable.

The other possibilities are that the power supply does not supply enough power for the system (which I doubt unless you have done some serious upgrading to the Video card and/or processor), or else there was some damage done to something on the motherboard via static shock during the PSU switch.

Upgrading power supply


The next time you get a PSU. Tell them what you have. Apparently you got one that is not compatible with your compaq.The power (500 wattage) will work with your MB.
Get an OEM PSU from Compaq(HP).
