Recently my power supply fan keeps revving up randomly even when Im barely doing anything on the computer, it has never done this before (had it for at least 3 years now) it is also emitting a smell every time it revs up not sure what the smell is but I can only assume it is a burning smell. I have also checked for dust and or any faulty wires and nothing appeared to be wrong in those areas.

It is definitely coming from the power supply and my PSU is definitely powerful enough for my PC so I can only assume it is coming to an end.

I am going to replace it, can someone tell me which of these two PSU's are better as the more powerful one is cheaper and im not sure why?

Also is semi modular cables or fixed better, currently I have fixed.

Any help or advice is appreciated. Also my PC is yet to crash and has only been doing this for the past two days, should I maybe leave it for a bit?

Solution
The CS PSU would be better. Heres a page that tells the difference between the different versions
