Hot PSU

post #1 of 17
Thread Starter 
Hello guys, long time no see.
I've a lil' question regarding my PSU's heat (a Corsair TX750)

During gaming it tends to get very hot, almost to the point of too hot to touch, and practically acts as a heater during these already-hot summer days, heating my room significantly, so it's not the most pleasant feeling either.

But that's not my primary concern, my primary concern is - should it be heating like this? -- Take a look at my rig, having an OCed CPU, a duo of GTX 275 and an additional 8800GTS probably does require the PSU to sweat, what do you think?

And for the record, yes, the PSU's fan is working. tongue.gif

Thanks~

Hmm seems very odd, My PSU never actually puts out any heat even during gaming or heavy Prime 95 load.

Maybe there is something wrong, or perhaps the fan is a bit useless. Has it always put out alot of heat?

Well yeah, I've never remembered it being cool

So it's always usually run quite hot? Still seems odd, cause all the power supplies I've ever used or seen always put out cooler air.

It's a 80+ Bronze, so it's effecient, and has a single 12V rail, but idk how many Amps are on it?

What TX version is that? (provide a link to it if possible)... also I see you're in Israel so I take it we're talking about 230V mains?

Yes. It is a Corsair TX750W.

My TX750 was always warm but never hot.
Maybe just because your putting a lot of strain on it, but I wouldn't think it would be hot.

I think I might have an explanation.
Since I have 3 hot cards literally sandwiched, and my 8800GTS is almost touching the PSU (You can only put paper or something between them, nothing more XD That's how close it is), the 8800GTS might be "stealing" the PSUs air, because the 8800GTS' fan is ahead of the PSUs, and the air it intakes might be actually the air that's supposed to be reaching the PSU, for it's fan to intake.

Basically, maybe not enough air is reaching the PSU because the 8800GTS "eats" most of it before it arrives and that's why the PSU is hotter than usual. (In addition to the stress I'm putting it through ofcourse.)

All power supplies put out hot air,it is part of the AC to DC conversion process.I have a TX750 mounted externaly on a Dell Optiplex (so I can run a 275 gpu) and it always puts out hot air,in fact all my power supplies put out hot air,its normal.
