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.

Hi

This seems like a power management problem on the motherboard.

Disconnect the power cable. Remove the small silver CMOS battery for 2 minutes to clear the BIOS Memory. Reinstall the battery and reconnect the power.

Look carefully at the power lines coming from the Power Supply Unit (PSU) and make sure that no one power channel is powering an unequal load of devices. Try and divide the load as evenly as possible amonst the power lines.

If none of this solves the problem, then consider upgrading the fitted 300W PSU to one with a higher Wattage, as 300W is on the low side for current standards. 450W-500W is more typical nowadays. The higher the Wattage you can afford (up to a 650W maximum for this particular specification of PC) the better

A higher wattage PSU will work well within its capacity and therefore under less strain than the current one. The symptoms you describe could be signs of the current PSU straining at the limits of its performance range to power all the devices inside as well as maintaining the computer's heavy workload of interaction with all the devices connected to it.

I hope this helps.

I just bought a used Antec EA 380 PC. \r\nHow do I re-set the user name and password ?


If you know the current user name and password, log on to windows, go to control panel, go to users, create new account, create new account and add password. Reboot using the new user name and password.Then go into control panel and delete the old user. That should fixya up.

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.

No it will not. The motherboard has voltage regulators which correctly distributes voltage through the integrated circuits to the chips/capacitors/etc. that need power. The only reason you would need a stronger PSU with more output wattage would be if you had lots of internal parts that drew a lot of power (such as 4-way SLi cards with power adapters plugged in, sound card, 4 hard drives, 4 optical drives, TV tuner, lots of fans, etc.). A setup like the one I just described would probably need at least a 750 watt PSU. But in any case, you could have a 2000000 watt PSU and it would not fry the board due to the reasons above.

I want to upgrade the PSU on my HP Pavilion a1140n


Go as "big" as you want -- the GPU will only draw the amperage that it requires -- it's not a mattter of pouring 2 liters of gasoline into a 1 liter container on the floor, while trying to keep the floor dry.

Computer wont turn on with 750 watt power supply


Make sure the PSU itself isn't dead, if not, then make sure all the plugs that were required before in the 300 watt, have plugs for the 700 as well. There is also a small chance the motherboard cant handle that much wattage, if its an older model.

Hp media centre m1180n wont power up after power cut


most likely it was the psu. You can actually test it yourself by buying a psu tester made by Antec that you should be able to buy in stores. It's a cheaper alternative to buying a PSU and just hoping that was the problem.

your manuals should tell you what the min req wattage for your motherboard and video card are the motherboard is more important of the two since it will provide power to the video so 600 would be quite enough I would think consider the electric bill on the 750 watt is pretty steep
