Power Supply For P4 Computer

  Sagar-231333 19:29 15 Jul 2003

Hi! I am upgrading a three year old computer to a Pentium 4 Machine. I gather from the information people have given me, I need to upgrade my power supply, which is a 300W power supply. the power supply needs to be 450W and above.

I have not bought a power supply before and would like to know, what I should look for when searching for a power supply.

Any help will be greatfully appreciated.

You need to specify a supply that suitable for a P4 - it has a small additional plug direct to the mainboard which the AMDs don't have. Whereas bigger is better, I run my P4 2.4 with everything fitted on a 350w unit without problems. You shouldn't have any problem sourcing a P4 suitable PSU - expect to pay around £15-£20 or so.

The information you have been given is partially correct. You will need a new power supply for a p4 machine, as motherboards supporting Pentium 4's have a different connector to the one that your will have. However you will not need one above 300w; you can get 250w p4 approved psu's although I would not recommend them, especially if you wish to install multiple drives be it hdd, cd-rw or dvd etc. I got mine from a company called CPC whose website is click here. You can also order over the phone. Their tel no is 08701 202530.

I had to have my Advent P4 psu replaced (under service agreement) a year ago. The original 300w Fsp group inc. model was replaced with a 300w Atx model. List price according to the service report £89.98. Who is robbing who????

Hi, You will need to change your motherboard as P4 CPUs need a special cradle for the heatsink. Cheers, Bill

Well, whatever advice you take regarding a new PSU can I offer a piece that comes from long experience: do not buy a cheap model. Anything under 50 GBP can prove problematic and a nice quiet one may set you back a bit more but they are worth it.

I will repeat one of my on-going messages: the PSU is the heart of any PC - if it is not up to the job then the whole machine is useless.

I'm off again!

See click here. 550psu for £21. I use one on my P4 and its steady as a rock. It does not however have a switch at the back. You need to switch off at adapter before pulling out the plug. Good luck.
