Phenom II x4 955 BE 3.2 GHz
4 GB DDR3 1600MHz HyperX Blu
1TB HDD Hitachi Deskstar 7k1000.c
160GB Western Digital WD1600AAJS Caviar SE (both of them SATA)
PowerColor ATI HD4850 512 GDDR3
Inter-Tech Energon EPS-650W PSU
Old timey ATX Tower computer case, like, at least 10 years old, which I keep open
The problem I am having is that the PSU fan always seems to be going at full speed, even when I'm just sitting around in Windows, not really doing anything. Actually, it gets really loud almost as soon as I turn on the PC.
I had the same PSU, and I could barely hear it, on my previous build as well, which was:
Abit LG-95C (socket 775)
Intel Pentium Dual Core E6500 2.93GHz
ATI HD4670 512 MB GDDR3
2 GB DDR2 800 MHz (I cannot remember the brand)
Now, I've read around on the internet and apparently the "input" demanded by this PSU is "230V", while all the outlets in my house are "220V". Could this be causing the PSU to work overtime *all the time*? Then again, I had the exact same PSU and it never was as loud as it is now...
Also, I'm a bit worried by this as well:
Please look at the +12V rail. The way somebody explained it to me, that means that there's too much load on the 12V rail, which is why it's a little low. I may be lacking the amps needed on that rail.
Is that something I can fix? Is it something tweakable?
Something I forgot to mention, which is kinda' dumb, considering it's the most worrisome thing:
Whenever I restart my computer from Windows, it hangs on the BIOS screen (the "Press Del to enter BIOS" or whatever). It works just fine when I turn it on, but if I have to restart for some reason... I have to turn the computer off and turn it on again.
I have not OC'd anything, everything is running at stock values.
I'm fairly sure this is also related to the PSU somehow, yet I'm not *completely* sure...
Software isnt the best way to check your voltages, its not very reliable, it looks like your system doesnt report right. Check your voltage in BIOS and see what that says, it should be much closer to 12V than what that says, and looking at those temps it would appear your system is at idle so its not that you are drawing too much current from the unit and causing the voltage to drop because of that.
As for your PSU wanting 230V and your outlets all being 220V, thats not a problem, US power is 110V, 115V, or 120V depending on what you consult, the nominal RMS voltage is 115V but some things refer to it as 110V or 120V, its all close enough and well within the range of noise, same goes for 220V-240V power, its close enough, and assuming your unit is the one in the PDF below, its active PFC makes it much more willing to deal with variance in input voltage as it just steps them all up to ~350V internally anyway so its much less picky. http://www.siewert-kau.de/en/sk/products/pdf/500386.pdf
It's 220 in all Europe, nowhere is 230, don't worry about this, 230 is something like "maximal nominal" But something seems to be quite wrong with this PSU. Problems with hot restart means it needs to be switchet completely off, before being able to provide the little extra current, necessary for rebooting, and high fan speed, probably caused by overheating /somewhere inside it/ looks again like working on the edge.
