Hardware Help needed

[3.5G]

My PC
--
Intel Pentium 4 3Ghz LGA processor
Intel 945GCCR mother baord
1GB RAM


my power supply was having some problem and today I changed it
but the old power supplies output is 450W and new one is 350W

after I installed the new one when I browse or do anything in my PC it shuts down automatically


Does the output power 350W enough ?

It can't be a prob with the PSU, try reconnecting all the wires this should definitely help!

How Much Power Do You Need?

Each power supply has a certain wattage based on their maximum output power. Common wattages range from 300W to 500W, although for a high-end gaming power supply wattages of 500W to 800W are common. Some units even go up to 1 kW of wattage, but this amount of power isn't neccessary for normal users.
For a typical gaming computer I would recommend at least 500W of power, although you may need more or less depending on your system. It would be wise to research into exactly how much power your various components will require, and then get a power supply with at least that amount of power.

After reading few web articles I feel like going 4 a higher voltage power supply
any one who often play games please tell what is ur power supply Output ?

your problem may be in the processor fan, PSU cannot cause this problem. The thermal paste may not be sufficent or fan is not properly fixed. Any help contact us.

I doubled checked the fan it is fixed properly.

this is what happens

"When using da PC suddenly all fans get stopped but still the power LED is active, and I am using a 3G modem , that modem is also working I mean the modems power LED is active"

so its not because of the thermal paste or Heat sink. also if it is bcuz of processor heat is getting high the PC should restart but it is not restarting

CPU overheating causing restarts

Aren't there any issue called power supply overload ?

It could be the Power Supply, those unbranded Chinese ones can’t maintain the rated power output. If the rated wattage is 350W, then that is like 200W in reality. Replace it.
If you are buying a cheap Chinese one then get atleast a 450W (that should give you at least 300Watts). Else buy a branded one with a rating of 350W or 400W.
