How do you position your hybrid PSU?

[RainingTacco]

The question is simple. Do you position it with fan facing bottom, or with fan facing upward[so it will get intake air from inside the case]. I heard that hybrid PSU should be placed with fan facing upward, since they can accumulate quite a lot of heat, that is otherwise trapped when facing downward.

I have Corsair RMx 850.

if my case has a filtered intake at the bottom for my PSU, I always have it pull its own fresh air and not have to potentially take in some heated up air from inside the chassis myself.

What computer case? Normally if the bottom of the case have an opening for PSUs then the fan will face down.

Case is Meshify C. I have it positioned downward, but i wonder if i should position it upward. The PSU ceiling is pretty hot when i touch it, fans will not start up until 340W of draw power IIRC, that's quite a lot of heat to dissipate.

yeah, keep the fan downwards for the bottom intake. Better to breath fresh floor air than GPU heat.

The PSU case will heat up no matter what, as it's designed like that... a lot of modern designs connect hot chips to the case using thermal pads and the case behaves like a heatsink. It's a good idea, as the case of the psu is in turn connected to the whole case, so the whole case of your computer will act as a heatsink.

So, it's actually quite good that the case of your power supply is warm.

 

Other than this.... warm air rises, so it won't be much of a difference if you install it fan up or fan down.

Fan down, cold air comes from under case, goes out through the back

Fan up, cold air comes from the back, goes up into the case.

 

The power supply's components are designed to work at up to 90-100 degrees just fine, and the fan inside will proabably start spinning once you go over 80 degrees Celsius.

So, I wouldn't worry too much about it.

I mount the PSU fan pointing up, unless there's a shroud, because there is absolutely no reason to mount the PSU with the fan pointing down if you have a quality PSU.

This is fucking hillarious  Man you've made these memes yourself? I mean good for you, that even at 40-50 years old, you can make quality memes

And btw seasonic recommends to point upward their hybrid PSU but i can't find this info for corsair products. Jonny, maybe pass the info to corsair team and make them update the FAQ?

They won't.  The "Case Designer" in the memes are the ones that work at Corsair that put shrouds over the PSUs and make the structural integrity of the case completely fail if you try to drill them out.

 

The Spec Omega is the only current Corsair case that doesn't shroud the PSU... and it's only a "meh" case.

As long as it's not on carpet, and it has a dust filter. Otherwise I'd opt for facing up into the case (if the case supports it), that way you're not filling your PSU with dust or choking off its air supply.
