Corsair's TX750M 750W is advertised as being able to maintain full 80 Plus Gold power at temperatures as high as 50C, handy if you live close to the equator or don't like cases with decent airflow.  [H]ard|OCP tested it at 45C and found those claims to be accurate, with even better performance at reasonable temperatures.  The 7 year warranty, decent accoustics and a price of around ~$100 make this a competitive product and one worth considering for your next build.

"The semi-modular Corsair TX750M claims to be the perfect PSU for high heat case environments as it is rated for continuous output at 50C. We will test it in the hotbox up to 45C, as that is torture enough. Does it deliver Gold rated efficiency and great power inside the incubator?"
