Hi all,

I bought an Ahanix MCE301 case with Ahanix 350W ATX Power Supply. I found that my system could not boot-up.

I bought some no-brand DDR2 from ebay. I thought my DDR2 failed. So I borrowed my friend's DDR2 Memory (Kingston). My system started to boot once every 10 times I turn it on.

When I looked at the BIOS (Motherboard Intel DG965OT), it shows
12V PS is at ~12.2
3.3V PS is at ~3.33
5V PS is at ~5.1
1.5V PS is at ~ 1.26 !!!!!!
CPU PS is at ~ 1.28 !?!??!?!?

Is my 1.5V PS too low and causing the boot-up problem??? My no-brand DDR2 does not seem to work well. My friend's Kingston seems to work from once a while..... Does it make sense??

I think I may need another power supply, am I right?

Please comment!
Thanks!

Thanks for the reply mpilchfamily.

Currently, I only have
Motherboard,
Onboard graphics,
One DDR2 1G DIMM,
CPU Fan

My goal is to get into BIOS at this moment. No HDD or DVD is connected.

Do you think the 4 items above would require 350W ATX PS? Do I need 400W PS? (350W seems to be reasonable to me since my old PentiumIII has 300W PS and seems to work fine with 3 HDD.... may be CPU is burning much more power now..... I don't have experience with Core2Duo system)
