PSU Temps

Go to solution Solved by Stefan1024,

All components in a PSU can normally handly up to 80°C at least.

 

But as you have a "no-name" PSU they cheaped out on the capasitors and put only 70°C rated ones in. If you heat them to much they loose the capacity quite fast over time.

Hi, I know this site is mostly for guys with some cash for latest rigs. I'm an enthusiast with no money, so I worked with all I had. 

I wanted a quiet pc and the smallest form factor. But no money. I found at home an ASUS PL5K-PL AM SE motherboard, an intel q6600 cpu, with stock coller, and a no name power suply.  I made myself a pc case from a box that i found in a store. Size of a shoe bok but a lot harder material. And I startet building. I have some versions of that case so far, but now i run into a problem. 

 

My new power suply, MS-TECH 400w,with small design. (12,5x10x6,5 cm). the fan was verry loud so i mannualy conected it to a 5v usb cable to lower the speed.

My question actually is, how hot can i run the psu, but be safe. 

 

some details, beside some c++ learning and youtube at 1080p witch really uses my cpu I don't use it so intense.  And i dont have a gpu. im using on board video

thanks for any help

I think it should be fine, haven't heard of the brand before, which isn't too good, but if it's below recommended temps than there shouldn't be anything to worry about. 

 

Also, nice thought with the shoe box lol.

thanks for such a quick answer. assuming my hand is a termometer. if i can hold my hand on the psu its ok right? if it was over 60°C it woult burn like hell, no?

 

and another question, my cpu, the q6600 its known for oveheating. i have it in 60°C at idle. thats something i should worry about? at 1080p youtube full screen it runs at 75-78 °C with 1600rpm

Err, that psu is udder crap. If you load it anywhere near 400w its gonna give you a nice firework show.

Letting that thing get even hotter than its supposed to wont do you any good....

my estimated consumtion with the mastercooler site is arround 200-250 watts! so i think its ok that.

Well measuring the temperature of the PSU is tricky, since the temperature of the PSU case is way lower than the temperature of the components itself. Also do NOT open the PSU to measure the temperature with your hands when it is powered on!

A thermal image camera would be the perfect solution. Even thermoelectric temperature sensors can be dangerous due to the high voltage inside the PSU and the (usually) thin isolation on the probes. Do you have any chance to lend one for free? I lent one trom my university once.

 

As you limitted the fan speed and pull 250 watts from a low quallity 400 watt PSU it probably overheats. Do you have a spare fan that is better than the one on the PSU to replace the stock fan?

i kind of figured it out so i found a silet fan that is wey beter, it is still worm the psu but much better! and its at full speed, like 1700 rpm i think
