3.3V rail extremely low

Specs: Windows 7, Intel Core2 Quad Q8200/6GB
My old cool-max 650 Watt PSU had a low reading on the 3.3V rail and based on the reviews I assumed it was the power supply.
I had it replaced with an Antec 750 Watt and the readings seemed to be about the same.

Video card:Gigabyte Radeon hd 6770
Processor:Core2 Quad Q8200
Ram:6GB
Inputs:Razer mouse/keyboard,webcam,speakers.
Hard drives:2 7200 1TB/500GB

+3.3V -- 1.5V
+5V -- 5.03V
+12V -- 12.03V

Were you having some sort of a problem that you suspected was due to low voltage on the +3.3v rail? Or did you just see the low reading, panic, then run out & buy a replacement? Where are you getting the voltage readings from - the BIOS, software, or a multi-meter?

I would worry if those readings came from BIOS.

I was getting the readings from a software, I'm pretty sure it shouldn't be that low and if there actually is a problem I'll most likely get a new one. The one I have currently installed my friend's psu he plans to use in his new computer which he said I could test if my readings change.

Don't trust third party monitoring applications, always compare BIOS readinds and third party apps to see if it is showing the truth.
