My system configuration is:- 1) CPU- Pentium D 915, 2) Motherboard- ATI Socket RC410, 3) Memory- 1GB DDR2 667MHz, 4) Modem- PCI Internal modem 56K, 5) Sound Card- Creative SoundBlaster Audigy 7.1, 6) Optical Drive- Two DVD writer, 7) HDD- Seagate 160GB SATA@7200RPM. I wanted to know that how much wattage I need for my Power supply unit; at present I have only 350W PSU. Please answer if anybody know.

By today's standard a 350W PSU isn't very powerful, but if you are going to use the onboard graphics then you should be ok. If you are going to eventually add a dedicated graphic card then you should consider a PSU with 450W to 500W.

A 350 watt PSU is fine for that system. I doubt the system pulls more than 175 watts at it's peak, likely less as the 915 has a 95 watt TDP.

As a rule of thumb, I like to draw no more than 2/3 of a PSU's max rating with a system, assuming I have a quality power supply to start with.

The advertised wattage of power supplies is a little like stereos or believing a used car salesman

I go for a brand name first then wattage

The first 2 PSU's dynapower and raidmax, I wouldn't waste my money on the shipping

You will have to go down the list and hit 35$ or more to get a true rating

It would be nice to be able to see these PSUs so that you pick them up to see which are heavier than the others, the heavier ones generally have larger caps and better transformers. One thing you can look for when shopping online is to look for a efficiency rating, you want one at about 80%.

Thanks to dc3,dpunisher,DaChew for your valuable information. I am using my onboard graphics I don't need to install a graphics card as I am not a gamer. So, I want to know - Is my current PSU enough for a stable system?
