From 300w psu i change it to 450w will that be ok?

It really took me a long time to solve my problem bout my computer, and here it is i found a nice site to share my problem hope you guys can help me solve my problem. im always experiencing a problem regarding with my power supply everytime i purchase a new power supply it will work only less than 6 months. one of my friend suggested me that i will replace may atx 300w power supply to atx 450w and she explained me the reason why i should replace it,so i think she got a point and the other reason is atx 300w power supply is almost face out, so i follow her advice and buy a atx 450w power supply.when i tried to turn on my computer using a atx 450w power supply it does not work but the LED in the motherboard lights, but the fan from the process is not working, no beep sounds from the board, i try many times to check all the connections and i think i connect them in proper. i have a p4s133 asus motherboard. Is anyone familiars the connections of a p4s133 asus motherboard? because im a little bit confuse with the connection beside the motherboard supply the AUX ports i think, should i put a supply on that? what should i check first to solve my problem? and replacing a atx 300w power supply to 450w power supply will that be ok? should i separate the power outlet of my monitor? because my monitor is connecting to my cpu. your reply is really a big help for to solve my problem... thank you!!! ivy

Ivy My field is in home appliances. I do fix my own computers and have replaced a few power supplys. The only thing I could say to you is go back and recheck your connections. They should only fit on the bord one way. The other connections for the hard drive and cd drives and so on really dont matter. so good luck and I think if you recheck it all the computer will work.

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.

New build pc no boot... black screen

Try to remove the battery from the MB, and next time you try to install WIN XP, when you are asked how to format your drive, chose quick NTFS formatting; disable floppy drive in BIOS, because it might try to boot from it (and I suppose you don't have one), and in boot sequence (BOOT DEVICE PRIORITY) set cd-dvd as first, and HDD as second, and turn off any other device as bootable
