I've just finished my first PC build (picked and assembled everything myself). The pc works better than fine (at least it seems so) but I haven't noticed any +3.3V power being used by anything. I don't know if this is normal or not. I didn't find any info on the matter through google, so now I ask in the best hardware forum. Details to follow:
Gigabyte gtx660oc 2gb
Intel core i5 3570
1x8GB kingston ram
1tb WD caviar green
120gb Kingston hyperx 3k ssd
LG dvd optical drive, 2 case fans
Fortron (FSP) Epsilon 600W
The video card is factory-overclocked, the CPU is NOT overclocked.
My BIOS (Health section) lists CPU and System temperature and fan speeds and the following voltages:
CPU Vcore: +1.032V
+12V SYS: +12,022V
+5V SYS: +5,103V
Nothing mentions +3.3V.
My PSU is the only component that I kept from my old PC, since it's a decent brand, almost new, and supplies more than enough power even for my new build. On my old PC it was working fine and in Everest I saw that the voltages on all rails were normal (including the 3.3V rail). On my new PC Everest can't detect my mobo, hence I can't use the program to check voltages. I used the Fox One utility, which comes with Foxconn mobos to check the voltages. It reads 5.02V on the 5v rail and 12.0 on the 12v rail, but it reads "----" on the +3.3V.
I am not very worried because the pc runs so well and I expect this will turn out to be perfectly normal. But better safe than sorry, I want to ask if I should be concerned. Thanks in advance!
+3.3 V - Chipsets, some DIMMs, PCI/AGP/PCIe cards, miscellaneous chips
+5 V - Disk drive logic, low-voltage motors, SIMMs, PCI/AGP/ISA cards, voltage
+12 V - Motors, high-output voltage regulators, AGP/PCIe cardsI always use OCCT for that stuff ..... it loads, monitors and graphs the results
