Hi,
I just got mine a few days ago and put my new rig together ......... and this thing is getting really hot to touch ...... is this normal with this PSU or do I have a one thats defected !!

I checked the PSU fan and its working but not that fast !! the air coming out of the PSU isnt that much either, again I dont know if thats normal with the current PSU ..

All I have connected to this PSU is my Q6600 stock speed for now, 8800GTS , 2 HD's and my DVD-Rom .. this all should be a joke to this PSU !!

so what's going ?! Is there a way to check my PSU's output or load to see if everything is working fine or any of the rails overloading ?!?!

help help .. thanks

I have a very similar setup as you (check my sig), except with 2 more hdds, and the E6700 instead of the Q6600. I just installed the HX620 also. I don't think you should worry about the heat. A 600+ watt PSU is not going to be "cool" to the touch, or even warm to the touch. Unless, it's burning your hand when you touch it, i wouldn't worry about it. Mine runs pretty hot also. As for overloading the rails, everything you have should be well within the range of the PSU, like you said.

I have a HX520 mated to an E6600, 2 Gig ram, eVga 8800GTS 640, and it runs cool and rock steady even in intense gaming. I have another HX520 mated with an old P4 3.2 Ghz cpu, 2 Gigs of ram, and a VisionTek 1950 pro. Both run cool as a cucumber (all three temperature zones less than 93 F under light load, less than 110 F under heavy and extended load - stock speeds on both). A friend of mine has a 8800GTX mated with an HX620 (E6600 and 2 Gigs of Ram) and his runs "cool" as well. If you've got good flo-thru in your case, it should run no greater than "warm to the touch" unless your are running above, say, 70-80% of available amps and overclocking like crazy. The HX620 is a beefy PS and can certainly handle the load you have. What case do you have? Have you run SpeedFan or TAT to see what temps your processor is running? And, although rare, at least for the Corsair series of HX power supplies, you could have gotten a faulty one.

What is strange, and related to this conversation, is the range of opinions on NewEgg regarding how hot or cool these units run. I guess it comes down to how much total load you are putting on the PS.

hmm you guys ready for the stunner !!! I just noticed that the PSU fan isnt even spinnning , the first day i ran the system it was spinning but reaaaallly realllly slow ... so I thought maybe it will go faster once there is more load , but just right now I looked at it and its just dead silent !!! I guess RMA or Warranty replacement from Corsair .. thanks for help though !!!

leefuji have you tried PM'ing XMSyellowbeard of Corsair support?, he's always been quite helpful in these (rare) cases.

mousemonkey:
no i havent , I'll do that though to see what he has to say !!

thanks !!

haha, yea, a dead fan would definitely cause the heat problem. thank goodness for the 5yr warranty with that HX620.

hmmmmmmmm , ok I got another HX620 PSU , brand new ......... hooked it up ...... the fan was spinning after a few minutes it stopped just like the previous PSU ?!?!? what the heeck is going on ?!?! do you guys think that there might be something wrong with my mobo that's killing the fan or messing up the fan sensor and making it stop or something ?!

the same thing happend on both PSU ?!

The system is running fine ... no errors or freeze ?!?!?!?!?!?!

The PSU does not get info from the MOBO to regulate the fan speed. It has an internal sensor. If the fan is turning itself off and on or regulating its own speed, it is most likely working properly. How is your airflow in the case and what case do you have?

Airflow is really good , I have two fans , one sucking in air and another pushing it out from the back !! The thing i'm really worried about is that the fan is never coming back on not even the next day when the computer was turned off and the PSU is getting really hot ..

exmaple , the 1st day I powered on , fan spin for 5 minutes and stopped .. I had the system on for about 2 hours .. and the fan never came back on and psu was getting really hot !!

corsair psu are over priced and over rated and they do get hot - heat is from low effeciency - the heat is the waste from conversion

send it back and get a silverstone!

I hope they aren't having Quality control issues, my 620hx is in the mail as we speak.

i used a 520 and was really dispointed by the heat - the psu works great but its too hot

I just tried the paper clip thing on connecting the green wire and the black on the 24pin just like they had it explained on Corsair.com to test the PSU ... and guess what ... the FAN did not come on !!!

I'm reallly disappointed ..... what happend to Corsair ?! Two PSU's from 2 different places and the same problem ??!!

For high requirement solutions, buy Seasonic, Silverstone, or PC Power&Cooling. For low cost mainstream solutions, go with Antec or Fortron. For all, make sure PSU is 80+ certified at minimum. 70% does not cut it anymore.

Corsair does make the best memory though. Always performs as advertised.

silverstone are the best psu's

i have been using them only for over year and nothing come close
