Hi all,
You may or may not have seen another post I submitted regarding boot
problems with my Abit BE6-II motherboard. This has led me to test the
power supply in my computer. Could someone tell me what the numbers below
mean for my power supply. Can I conclude that the supply has not gone
bad? What should the ranges be?
Please note the I/O Voltage under the BIOS section below. Under Softmenu
III Setup it is set to 3.50 V but it seems out of spec.
Thanks for any help you can provide.

When I use a Radioshack multimeter set to DC Voltage I get the following
results.
Same through a wire attached to a hard drive and two case fans as it is
through a wire connected through both CD-ROMS and the floppy drive :
Red Wire: Steady 5.10 V
Yellow Wire: Steady 11.97 - 11.98 V
Via MBM5 I get the following results:
+3.3 reads at 3.26 V
+5.00 reads at 5.08 V
+12.00 reads at 11.92 V
-12.00 reads -11.94 V
-5.00 reads -4.99 V
Core 0 reads at 1.65 V
From the BIOS:
CPU Core = 1.66 V
VTT = 1.50 V
I/O = 3.24 - 3.26 V (I wonder if this is my problem)
+5V = 5.05 - 5.08
+12V = 11.91
-12V = 12.03
-5V = -5.04
Standby Voltage = 5.02
System as follows:
AOpen Switching Power Supply FSP300-605 (300W):
Pentium III 700 MHz
Crucial PC-100 SDRAM
Creative GeForce 2 Video Card
Creative SB Live Value Sound
Linksys NIC
2 Hard Drives
1 CD-ROM
1 HP CD-Writer
Sony CPD-420GS Monitor
3 Case Fans (2 Hooked to Power Supply - 1 Hooked to MB)
