power supply effect on cpu temps when overclocking

[rieds]

i was doing some research on overclocking my fx6100 on a asus 990fx sabertooth and found some settings that other people have used to push it to 4826 stable. but the temps are to high for my liking. i saw where someone mentioned that the wattage of your powersupply when overclocking can effect your temps a pretty fair amount. that being said my current power supply is a ocz 500w extreme. would getting a say 750 power supply bring my temps down?

Never heard of the wattage/quality of a powersupply effecting temps.. stability and max oc maybe but not temps..

 

The only way it would have that kind of effect would be air flow, if it helped vent more air out of your case. If that's the case, better case fan's would be a better solution.

ive never heard of it either... could they be talking about the psu temps?...like a drawing 400w from a 700w will be cooler then drawing 400w out of a 450w??

Your PSU has very very little to do with CPU temps.

I think he means its affecting temps in a more indirect way, his PSU is reaching maximum load causing it to heat up his case, which in turn causes higher temps on his CPU. So yes in that way it could affect temps.

thanks for the replys. i din't think it would have that much effect. i have the antec 920 liquid cooler. i'm told it's the best of the sealed systems. can i build a water cooler that would cool better?

Of course, Custom water cooling systems if done right can out perform the sealed system units, though not for the same price..

As far as I know, the PSU itself won't affect your CPU temps. BUT what voltages you set will. My CPU runs semi-stable at my overclock with my CPU voltage set to 1.425v, but runs perfectly stable at 1.45v. The difference in this is about 3C idle and 5C under load.

 

But unless one PSU blocks airflow in your case and another promotes it: Shouldn't be any difference.

 

--Edit: Although the previous mention of an overheating PSU itself is correct. If you're pushing the PSU too hard, it disperses more of the wattage as heat. And that heat, just like any other component, may be flowing into your case, raising the overall temperature. But honestly, the chances of getting more than 1-2C difference are very off. Especially since most PSUs use direct exhaust, pushing their hot air directly out of the case.

It will cost more then the self contained unit but it will perform alot better then what you have.
