Power supply getting hot.

nffc10 · 08-06-2007, 08:47 PM

I have an Antec Earthwatts 430W, reccomended to me by cewee1 and Kornowski and it's worked like a dream. Since i got my new computer it's been getting quite hot (52C - 55C) when under load. Is this ok? Or is my psu under a bit of a strain? I wouldn't have noticed if my i wasn't cooking in my room whenever i have my computer on. The rest of my temps are ok, but i think that because of my psu, it's heating up the air on the insdie of my case (i have 4 case fans though) and making all of my other components warmer.

My specs are:
AMD Athlon 64 X2 6000+
2gb Corsair XMS2 PC5400
Asrock Motherboard
X1950XT
80gb Maxtor HD IDE

Temps are:
System 35C/42C
CPU 39C/53C
AUX (PSU) 39C/54C
Core 37C/49C

P.S. Everytime i plug in my Belikn wireless usb adapter all my temps raise like 5C, anyone know why?

I would say that your pushing the PSU to its limits with that setup to be honest. Its got to be drawing near 400W to run it all, i was dubious about having a 480W when i had a similar setup.....

I would suggest keeping a close eye on the psu though, if its starting to get warmer than usual then try and get some extra cooling in there. The temps are ok at the moment but just watch them, especially with the hotter weather on the way....

I would have to agree with jimmymac, that is a LOT of high end stuff to run off of a 430watt. Especially the 6000+ and the X1950, they take a lot of power.

nffc10 · 08-06-2007, 09:10 PM

Cheers for that.

If i notice any more of a rise in temps then i'll have too look for a new psu.....again!

**jimmymac** · 08-06-2007, 09:15 PM

put it this way, i had an X2 6000+ with an x1950xt powered by and Antec 480W and it gave me no end of issues. Theres a good chance i had a problematic mobo but the psu might have also been on the edge.

the Extreme psu calculator put the estimated wattage on my setup at something like 428W so its gotta be near the edge....

nffc10 · 08-06-2007, 09:32 PM

Seems im cutting it a bit close then.

**oscaryu1** · 08-06-2007, 09:34 PM

Does it shutoff when playing games? Otherwise, get some case fans.

nffc10 · 08-06-2007, 09:44 PM

No it doesn't shut off when playing games or anything. It just makes my room into a sauna on a warmish day!
I already have 4 case fans, do i need any more?
I chacked on that extreme psu calculator and it sayd that i need 472W at 100% load!!!!

The eXtreme PSU calculator builds in an overhead into it's calculations, and it's actually a very large one. Your system is unlikely to be drawing much more than ~250W under peak load.

What you're seeing is your CPU temperature, which is generally unrelated to your PSU. Your system has no way of measuring your PSU's temperature. You can take a look at your voltages to get an idea of whether your PSU is overworked, but don't rely on your CPU temperature to be any sort of indication.

Additionally, lowering your CPU temperature isn't necessarily going to lower your room temperature. If you can reduce your actual thermal output (e.g. by undervolting) that will, but if you simply add more fans all you're doing is moving more heat from the PC to the room.

Thanks, last week i put the voltage of my processor from 1.4V to 1.375V and it loads cool and nice.

But i don't no how to change the maximum voltage it can recieve, that's stuck at 1.45V.
