Generally, how warm are PSUs supposed to be?

post #1 of 6
Thread Starter 
So I noticed that my 1200w started to get warm on some days, especially when draining power off the 6pins for the GPU, 260 SLi.

But on a single card, I was starting to get worried that it might get too hot and eventually die on me. (I've RMA'd this PSU 2 times, not letting this sucker fail AGAIN for the 3rd, I had to wait a good month for the store guy to give me a BRAND NEW one because it completely died)

How normal is it to feel around 40-60c? (My guestimate compared to a GPU)

okay I put up a thermometer in the fans of the PSU and had my friend record the temps every minute because I thought i had the exact problem.

on average(for my sig rig) is about 30 idle and about 50 under load(crysis 2), I didn't think that there should be any differences but this is what I found.

I'd say it's normal for you to have 40-60c in your PSU.

Mine gets pretty warm. But that might be because it's essentially fanless.

That depends a lot on the power supply. Are you talking about the air expelled or the casing itself? Some units use the casing itself as a heatsink.

Some reviews show the exhaust temperature given a certain intake temperature and load. Some examples:
