Quite a few of the cheaper power supply units are regarded as incendiary bombs or combustive agents. Insufficent components (mostly: too cheap components) will overheat and then...

Also a otherwise safe component might become underdimensioned if components of a(n off the shelve) computer are exchanged to "more"powerful" ones. Most likely the PSUs of complete systems made by most manufacturers or assemblers have little reserve/cushion/spare (I don't know the right word).

If you want to be on the safe side: check the PSU in your computer and calculate the max. power needed and replace it -- if necessary -- to one that may deliver at least 20 per cent more performance than needed at the max. And buy the products of reliable manufactures only.
