Der oops, I just realised I'm out of powersupplies.... I seem to have found 2 more harrdrives though.

Need cheap powersupplies........................... Cheap, but not cheap like its gonna blow up in a month or runs at 12.6v instead of 12v

How about instead of a cheap 300w PS, you get a cheap case with a 300w PS in it. Take a look at this case I just bought:

The case was only $49.00Can. That's about $30.00US. Got it at one of the local computer stores. :) If I wanted to go nuts, I can get it with USB and sound ports inside a drop down door on the front-bottom and it's only $49.00Can. :D

Do you mean cheap as in maybe running 6 months before poping a capacitor and frying your mobo and hard drive?

I don't worry too much about power supplies. 80% of the worlds PCs run on cheap power supplies. Of course, that doesn't explain why I put a 430w Enermax in my main system :)

Whats with this popping caps? i've never seen it. I don't even see how a PSU could be approved for usage that would have a cap blow caps blow when

1. gets too hot (140F+, won't happen)
2. Too much voltage (stupid design) 12v cap on a 12v line will not work OK
3. Voltage spike causes number 2 to happen

Der, I had a $5 PSu that "jumped" it made a pop noise and moved a bit, no cap damaged. The fuse was smeared on the lid of the unit and it looked like a group of 1 resistor, a diode, and a transistor were rather dark looking :)

Some one enlighten me how a PSU with crap capacitors will pass all those approval things (CE, TUV, etc). I always though you had to send in a parts list etc to the peeps that run those orginizations

Some capasitors just "dry out" over time.

Sony used to use surface mount caps back in the early '90s in their camcorders. They had a very low temp rating around 100 degrees. If you ever put your camcorder in the trunk on a hot day.... you cooked your camcorder! They were filled with a corosive electrolyte and when they started to leak... they would corroide through the multi layer boards. Very expensive to replace. Sony does not use those anymore. They should have use better components.

If your PSU manufacturer has used cheap parts then you may reasonably expect to have a failure at some point because of the weak link...

That would be bad.......

I can see how a power supply cap would blow (cheap psu) but i heard once or twice bout an ABIT mobo blowing one, or peeps blabbing about open cases are unsafe because the caps are gonna shoot off and damage yer eye.
