High Operating Temperature PSU

[mjelkman]

Hi guys,

 

I'm looking for a reasonably priced PSU between 450W and 550W for a relatively low end system (i5 4670K rx 6500 xt). Most of the PSUs that I've looked at have an operating temperature of 40 degrees Celcius, but I live in South Africa, and summer temps are regularly from 30 - 40 degrees here. I don't want to run my aircon for hours on end just to game (trying to stay environmentally concious and it seems counter intuitive) and I don't want to just not game for a week or two. I'm assuming the opperating temperature advertised doesn't refer to ambient temps that the PSU can function at, but I would love it if someone corrected me on that. This is my first gaming system, if you couldn't tell. If you're wondering about the weird combo of parts, I'm a broke student and I inherited the CPU. The GPU is new, so that I'll be able  to upgrade in the future and not leave too much performance on the table now.

 

Let me know if I'm being too paranoid about the temps or even if it's ill advised to run my PC when it's that hot for the sake of GPU and CPU cooling.

Operating range means outside (room) temperature can be 40 degrees and it's still fine to use the PSU. Internal components run hotter anyways.

 

The only difference between you and somebody from Norway will be that your PSU fan will most likely run more of the time, nothing else. 

 

If the PSU is 85% efficient and uses 300W under load, it means that roughly 30W will be dissipated as heat, which is easy peasy to cool.

 

Don't worry too much, just pick a PSU from a known brand that has decent efficiency and you'll be fine

Thanks so much. Puts my mind at ease
