On an older computer of mine, I had a power supply. ATX. At about the 7 year mark, the power supply blew and it took a cd-drive and a hard drive along with it. my hard drive was not backed up. My current computer, the supply is 3 years old. I had been noticing a grinding sound, and sometimes the fan wouldnt spin up, but I thought I could get away with it. Last night the final straw. The smell of burning rubber. Obviously this supply has been damaged now. It still works, the computer and everything, but im not taking any chances. This computer is down until I get a new one.
My question is, Can you reccomend a power supply thats not going to be too expensive, and wont blow in 5 years and take some friends with it?

A mainstream PSU like below will suffice.

Did you put this system together or was it from a VAR like Getaway or Dull?

A faulty fan is the most likely cause of a power supply failure. If a fan starts making noise, replace it immediately. It's not that difficult to replace a power supply fan. Always use fans with ball bearings.

Do yourself a favor BACKUP!

Ya, i guess I could assume theres no such insurance, sorry. Let me rephrase. What are things to look for in a power supply. I already know the wattage I need. At least 300. Are there really any other factors in this?

psu cost is proportional to high watts, steady output, and low noise. So if you get something loud that is rated high in watts (say a bargain 500W psu), that should be close to what you want. The newegg link above is a good choice imo.

Im not 100% sure what johnoh is saying, but a bargian 500W PSU will probably be junk.

When getting a PSU look for brands like Antec, Thermaltake, Enermax etc. Try to stick with well known brands, others seem to be cheap and very unreliable. Look for one with dual 12V lines with a combined total of at least 30A. Its not always the watts that matter, if you have only 10A on the 12V line and have a fifty billion gazillin watt power supply your still stuffed.... I think you probably get the point, heh.

other than the super-reliable and expensive PC Power and Cooling brand, failure rates among psu vendors are comparable. That's why if you want to spend $x and can get a 350W antec or 450W fortron, the fortron is the better choice.
