...super heated power supply?

So I just put together my computer made of a selection of newegg parts, everything seems to be running fine, except ...when I look in any sort of sensor reading software it says my power/aux is at 80 to 85°C. I'm not sure what the problem is here.
For starters it's this 600W PSU (the only remark I find relevant in anyone's cons is that the fan points downwards).
The fan inside is working, the PSU doesn't feel hot to the touch anywhere inside (nowhere near 80°C, in any case. Even if the sensor is at the top of the PSU the top of the case doesn't even feel warm. Out of the settings Low/Auto/High I have it set on high right now (was on Auto, high doesn't lower the temp, anyway).
It can't be bleed-off heat, since the processor's heat sensor is at 35 and the motherboard is at 30. The graphics card is at 45-55, and it's nowhere near the PSU.
So I was wondering if anyone would be able to help me with this. Either determining if the sensor is faulty (...maybe it only reports in Fahrenheit or something?), or if some component in the middle is legitimately at 80 degrees. It seems to run fine, but I don't want to damage it and I'd like to figure out what the problem is here.
Anyone have any suggestions or possibly any other sensor reading programs I could try? I've tried speedfan , pcwizard and CPU hardware monitor and they all seem to be consistent with their high temperature reading.

I used to just get whatever when it comes to PSUs, but I realize now that it might be the single most important component in terms of ensuring the continued reliability of your PC. You might want to consider returning that PSU and getting something from a more reputable manufacturer like Corsair (rebranded SeaSonic).
The graphics card probably eats up the power, but I'm not all that great with calculating potential power consumption of components.
To be honest, I wouldn't even try running your stuff on your old PSU unless it was a good brand and is in good condition. If it's of a certain age, it may not even have PCI-e connectors.
My electrical symbolism is a bit iffy, but I believe it's got 28 amps on the 3V, 40 amps on the 5V and 25 amps on the 12V. It's an NSpire from 2 or 3 years ago; It has power connectors for SATA, at least. It ran my machine fine before (including additional power for a Radeon X700 pro, which is probably at least a partial analogue to a PCI-e card in regards to power consumption). probably the same set up I have now except one of the HDDs and the optical drive are SATA.
what you are looking for is a 6 (2x3) or 8 (2x4) pin connector. most likely is the 2x3 which will be required by almost all ATI cards and most Nvidia cards.
wattage is another concern with old PSUs. you need to have a PSU with at least (i calculate while im drunk) 25 amps on the 5v rail for 2 SATA and 2 input drives. and 25 amps on the 12v rail.
your old 450W PSU should be ok for the new req unless it doesnt pass the connector test.
i honestly recomend the 550W corsair PSU without modular cabling. its a TX version if i dont remember. corsair is one of the best right now.
I wouldn't risk it even if it has the right connector for your video card. 25 amps is pretty low, you want at least 30 or so to feel safe with today's video cards.
