I'm looking for a Haswell-ready power supply that does not have a strong smell. I have a lot of allergies, and the smell of the new power supply I bought gives me a headache. It isn't a burning smell like the power supply is overheating. It is a smell from the materials the power supply is made of.
AFAIK, impossible to get.
What you are mostly smelling are component manufacturing fluids and flame-retardants (very poisonous). Yes there are allowed to be use even within the EU (even with the REACH standard).
The best bet is to buy a Used supply that fits your specs. If it's been run 24hour/day for a few weeks with good ventilation, most of the smell should be gone.
The other option is somehow to burn it in for a few weeks in a hotbox - outside or in a ventilated space.
I'm also thinking of how to solve this issue, and the above is the best I've come up with so far.
