agreed. And btw, nobody neg the OP. He hasn't done anything wrong.
Oh and OP, most people don't know crap about psu ratings, so there will definitely be quite a few people who will tell you it will work even if it won't. The answer is simple math.
To find the actual 12v wattage:
4A x 12V = 48w
to find the wattage of your system:
27w (CPU) + 23w (your graphics card) + 7w (mobo +chipset) = 57w.
Throw capacitor aging in and it gets even worse, because it is no longer safe to run your psu above ~80% load.
That means your psu can safely supply:
12v x 4a x .8 = 38.4w
You are WAY in the red. If anyone tells you otherwise, they do not know what they or talking about, or have been mislead by your constant claims of 150w.
And whoever told you it wouldn't boot if the psu was overdrawn couldn't be more wrong. Power draw under full load is typically morethan the startup current needed.
