Higher watte = less heat right?

[TheMidnightNarwhal]

So if I get a 850w RM for a GTX 770, and a 4670k there will be like alot less heat than using a 650w right?

[WoodenMarker]

If you're talking about the psu getting warm, it depends on the specific psu.

[Imabigmac]

no, a 650w and 850w psu will generate about the same heat. For that system unless your doinf dual gpu's a 850w power supply is not needed.

Heat from the 850w?

There won't be a lot more heat, as you probably won't be using all of the 850w power supplies.

I was thinking since it uses less of the total output it's less hot...

The RM series from corsair.

Not sure. Why does it matter?

That correct, though lets say you're using around 600watts. The heat on both the power supplies will be around the same. 

[TheMidnightNarwhal]

Not sure. Why does it matter?

 

Because I really like the looks and the cables of the RM series and the no fan thingy, but am worried about it getting too hot, so was thinking of ways of making it run cooler.

Alright.

It's designed to run fanless at low loads so you're fine regardless of whatever you get.

PSUs don't tend to run too hot (branded PSUs that is. Don't get me started on generic ones...) so no need to worry about that

[Dani360c]

i have an RM 650 and i does not get hot and the fan barely even spins, so no worries

[SeanAngelo]

the heat output on both PSUs will be the same, even if its a different wattage.

[meneervent]

RM is bad.

Get a S12G 450w.

[TheMissxu]

Maybe a better 80+ certified power supply could run cooler as it's more efficient. But it's probably negligible.

Yeah but I heard multiple problems about heat and stuff.

not on a good quality PSU like the RM unless it is faulty

[TheMidnightNarwhal]

 Like on hardocp, it failed 2 times, even with the replacement one.

[Arndroid]

The less wattage usage, the less efficiency you will achieve. Therefore that will cause loss of energy, which will cause heat. (and/or noise when bad quality components are used).

 

Using more wattage, the higher the efficiency will be. Therefore lesser loss of energy, which will cause lesser heat.

 

When using an amount of wattage close to the maximum wattage output, the efficiency apparently drops a little, but still will be more efficient then using only a small amount of wattage you can use with that particular PSU.

 

Edit:

Indeed, the RM750 and RM850 have problems with the fan kicking in to late.

Corsair said there will be a new revision of the PSU's having this problem. (But it might take a while before the stores run out of the current ones...)

 

Other RM[Wattage] PSU's don't have this problem.

Exactly, I think I would choose the HX, but I see problems with high fan noise.
