Odd Burning Smell

Specs: Windows XP Home, Intel Core 2 Quad Q6
Hello there,

Around a year ago I bought a computer, stupidly I failed to fit an adequate PSU and left the EZcool 500W sitting where it was, thinking this would be enough away I went!
Around a week later I noticed a burning smell, it slowly got stronger until the PSU eventually went pop. It was still under warranty so naturally I took it back, they fitted a new PSU, this time an EZcool 600w.
Around a week ago I noticed the smell again, it was quite faint but certainly noticeable - I wasn't taking any chances so I took it out and grabbed a test PSU from work, an EZcool 700w. All seemed to be okay until I noticed the smell again, extremely faint however.

Is my computer trying to tell me to get a decent PSU? I realise EZcool isn't the greatest of makes, but I didn't think they would perform this badly. On a side note, my computer is 100% dust free, temps on idle are around 42-45, everything else SEEMS to be working normally.

This issue usually occurs after around an hour or two of gaming, not even on the most demanding on games.

Any ideas? I have around £70.00 (GPU) to spend on a new PSU, I just want to be sure it is that that is causing the issue.

Intel Core 2 Quad Q6600

Thank you for your time.

Get yourself a good PS.
See response 3 in this:

New PSs often produce a faint smell for awhile, but it eventually goes away.

It's possible the faint smell is coming from something on the motherboard, not the PS.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

This was the original bad capacitor problem - has some example pictures.
History of why the exploding capacitors and which mboard makers were affected:

- he says there are STILL bad capacitors on more recent mboards.

Thank you for your reply!

Some very interesting capacitor images throughout that archive, I'll certainly look into that tonight.

I'm currently also looking at some new PSU's, any recommendations on my listed specs?

If your mboard has a PCI-E X16 slot and you are using a video card in that slot, the minimum PS capacity you need is determined by the video card you are using, or might use in the future.
You can go to the web site of the manufacturer of the video card model you are using, or might use in the future, and look at it's specifications, and usually you will find the minimum PS wattage capacity a system must have when that card is installed, and more important, the minimum amperage the PS must be able to supply at +12V (el-cheapo PSs often have inferior amperage at +12v ratings, and/or the max ratings are a lie, and/or they can't achieve the rating(s) continuously ) . That's often listed under system requirements.
If you don't see that, any video card with the same video chipset, including any added letters, e.g. X1950 Pro, or XT, or XTX, will have very similar minimum PS requirements.
Sometimes if you merely search the web with the chipset name and something else, you will find that info at the "hits".
e.g. X1950 XT minimum power, or X1950 XT minimum watts.

That said, nobody actually needs a 1000 watt power supply, even if they can install 3 high end PCI-E X16 video cards, and according to what I saw when I was looking at high end PCI-E cards a couple months ago, a decent 600 watt or 650 watt PS, minimum, will handle any current PCI-E X16 card chipset, even if the card is a X2 card (two chipsets on one card), or even if you have two PCI-E X16 cards in two slots.
