Low 12V on FSP 450

Hello,

I recently built a new system, with:

Pentium D 930
2gb corsair ddr2 ram
Radeon x1900xt
1 7200 hdd
1 dvd optical drive

I put in a Fortron 450W power supply (18A/18A on ATX 12V 2.2) to feed the beast. Now all the motherboard sensors that I have are telling me the 12V is too low--Sandra reports ~11.3V on the 12V rail, ATI Tray Tools reports 11.1. I pulled out a multimeter and checked the rail manually and it seemed higher than the software reporting. I'm just worried this could be adversely affecting my performance and want to know--is this something I could be doing wrong? Did I get a bad PSU and should return it? Or is a low voltage there just normal (don't think that's true).

Games and things seem to be running ok but I'm worried when the voltage is pretty far outside the normal 5% tolerance.

Thanks for any insight.

FSP makes good PSU's u are fine.



also the poster above me is absolutely correct.
