I need to monitor the PSU voltage & wattage levels.
Anyone know of a free piece of software which will allow me to monitor what the PSU and is up to to asertain if the demand on it is reaching its limit. I have used a wattage calculator and the report was that my PSU is man enough for the job. However I fear that this is not the case.

just to make a note.  Some software will not work correctly with your hardware.  If you can get a monitor from your motherboard manufacturer that would be the best to monitor your power.  Most of the monitors above will monitor your temps just fine, but when it comes to voltages they are not always accurate.  


Because I can I will make a rant about power supplies.  Your power supply is the #1 most important componet in your system.  If your power supply is cheap and sucks, your computer will also be cheap and suck, no matter how much you put into your other hardware.  Cheap power supplies can cause your system to have errors, hang, freeze, damage hardware, etc. The key here is to purchase HIGH QUALITY power supplies from brands like Enermax, Antec, Zalman, PC power and cooling,  Thermaltake, Sparkle.  I personally like Enermax because they give you more amps on your 12v rail then any other manufacturer except for PC power and cooling.  However, their price is a hundred bucks less the PC  power and cooling's price.  If you have the money, the PC power and Cooling power supplies are the best on the market hands down.  I think that Antec, Sparkle, and Zalman have resonably priced power supplies for what you get.  I also think that Thermaltake's power supplies are expensive for what you get.  

So the moral of the story.  If you have a generic or no name power supply and you are worried about it, Then purchase a High quality brand.  If you already have a high quality brand then I would not worry about it.  If you have a 300W high quality brand, and you have more then one HD, two CD-ROM drive, and a new video card that uses 12V then I would consider purchasing a new one

I've found Motherboard Monitor 5 to be the most accurate (when it is configured correctly), usually within 5-7% of the actual voltages when measured with a meter.

Definitely don't skimp on a power supply. I've always used enermax, and never had a problem.
I recommend EG465P-VE (The 460W model not the 430), its  very reasonably priced.

When testing your system  let the monitor run for a few hours, and run a stress test (sandra or prime95) in order to get an accurate reading.

When analyzing the results, most hardware is designed to accept a 5% deviation, so if your +12V line drops to anywhere near 11.5, or if your +3.3 line drops to anywhere near 3.1 its time to get a better power supply.
