Green Green Business

I previously asked about what could be wrong with my computer and gave symptoms…3 out of 5 said power supply. Before I go buy a new one…when I plug it in the green light blinks…does that mean it’s not the power supply but something else like mother board or??

when i change my power supply from the 115v option to the 230v option my computer wont boot up everything comes on but the green power light turns orange and nothing pops up on the screen. I need or at least think i need the extra power to run a new graphics card i just bought which requires a 450w power supply. any suggestions?

I Google’d it but all I found was a website with the following information:

Power supply colour codes

Blue -12
Red +5
Orange +3.3
Grey Power good signal
Green Power switch
Purple Sand by power
White -5
Black Ground
Yellow +12

I don’t know what the numbers mean, though, if it is even correct.
Thanks in advance.

alright so my 360 just got the red lights of death, the whole thing is flashing red, with the power supply having a green light, what does this mean, and what can i do, if i DIDN’T set a warrenty for it, nor do i know where any of that information is for it?

its conected rigth, tried woth different power cables in case it was the cable. but the green loight wotn turn on. does this mean something is wrong with the power supply, how can i fix this? thanks beforehand.
no noise, or fan activity at all

i read that the power supply light should illuminate green when RROD is there.. mine does not…. could my Power cord be my problem?
