Well, It is going to be a new build, with MSI 915 motherboard , with 3.2 ghz .. It will have 2 gig of ram... I have custom case that will have 3 lighted fans.. I will also need a PCI express video card.. So I am not sure on how big of power supply I might need..
In my opinion...No...it is not a quality unit. Things to think about...in relation to the negative effects of heat on the computer...That can be caused by the power supply. Manufacturers test their PSU's at a set temperature...from this their rating is determined... for most this No. is 25 degrees Celsius...which falls short of the temperature that most computers are capable of achieving. Given that a PSU will actually lose 2-5 watts per one degree of heat above the 25 Degree Celsius testing temperature...coupled with the fact that computers tend to run at 10 degrees higher than room temperature... In the summer time when the room temperature can easily reach 80 degrees F... your computer will be running at 33 Degrees C. or 90 Degrees F. So the...math can make...your 500 watt power supply into a 460 watt unit. In addition to this...what needs to be taken into account is that each degree that your computer components are operating at...under powered...adds more heat to the equation. Consider also...the possibility...that ratings given by the manufacturer of single components...such as graphics cards...need to be treated with skepticism...Manufacturers may minimize support issues and under rate the power required...in order to make a larger profit. The above has not taken into account...the issue of high quality vs poor quality units...Power supplies convert voltages from wall outlets to lower levels used by the PC. During this conversion, some power is lost as heat. The efficiency level of the PSU determines how much extra power must be put into the power supply to run the PC. A high quality PSU can help reduce the noise and heat generated within a computer system. The higher the efficiency rating the less heat the PSU has to deal with. Therefore heat is the computers enemy...The hotter the temperature your PSU is forced to run at...the poorer the supply of power the rest of the components will receive...which has been known to lead to such things as crashes, freezing, rebooting, BSOD’s, and video distortion, as well as partial and complete failure of other components. The fact is very few PSU’s are capable of producing the wattage that the companies advertise. I suggest...a quality 550w PSU...as the minimum one should purchase...to provide power to a PCIE card. But for a very good comprehension of recommended brand names, wattage, and models in listed categories...Plus much more...check out this link.

Well, I bought this Video card: Evga 512-p-2-n430-LR (gforce 7200GS pci express x16) And i got this Power supply: Sigma Power engine SP-535 535watt v2.01
It's probably a fine PSU, but with one sole 18A +12V rail and it being based off an older v 1.3 ATX spec (the current is 2.2, IIRC), consider that there are better units available to you from about everywhere. If this was for a Socket A or 478 CPU-based build, you'd probably be alright, but given the progress since then, it's really not a suitable pairing for a current build. Even if it does power the system up, you'll be running it at the edge of what it can put out, and that's not recommended. While you don't need to spend $500 on a PSU, don't try to go the cheap route...you'll usually pay for it later.
