Should I be concerned about my power supplies continuous output rated temperature? This is my power supply from Corsair by the way if that helps http://www.corsair.com/en-us/cx-series-cx650m-650-watt-80-plus-bronze-certified-modular-atx-psu-na. I noticed on the tech specs section on the website for this power supply the continuous output rated temperature is rated at 40°c. So what I want to know is what will happen if the power supply temperature goes above 40°c and should I even be concerned about it? I have quite a high end gaming pc build by the way. Here are my specs if that helps.

gpu: GTX 1080 founders edition
cpu: i7 6700
ram: 2x4 2133 mhz ddr4 ram
motherboard: MSI h110m pro-d
hard drive: Western Digital black 1tb 7200 rpm
ssd: Samsung evo 850 500gb

What if I'm playing a game that is intensive on the gpu and cpu and they get hot and therefore the ambient temperature inside the case raises above 40°c and therefore the power supply temperature raises above 40°c? My main question is that should I honestly be that concerned about the continuous output temperature of my power supply going above 40°c? I mean Corsairs top of the top line AXi series power supplies continuous output rated temperature is at 50°c which is only 10°c above my power supply. I'm just afraid that if my power supply goes above 40°c it will reduce the lifespan of the power supply and eventually fail sooner than expected. I'm very concerned about this because I like to play games on my pc but I don't want my power supply to over heat and die and possibly take other components with it to. Please help. Thanks.

It's more the incoming air temp, as that's what will dictate how much heat it can dump. Poor PSU's might inflate their ratings by saying that they will only do 600W at 30C, better would be 600W at 50C. So providing you manage your case temp (and maintaining 30C is really tricky, but 40C is easy.), then you'll be fine.

Question from Thomas-18 : "Power supply continuous wattage and peak wattage?"



The 650watt is the continuous totall wattage of this psu. Peak power is 715watts. Can be found in this PDF,
