It's a Codegen 450W, I don't even see that brand on that site's list.
+12V is 16A
------
With my current PSU, would switching up the molex plugs work?
Thats 1 amp more then the 250watt i have in the closet.... In its defense it runs a E6600 and low end video just fine...
I have seen too many Ultra PSU's mess up. just replace it...I suggest a good 500-600 watt only to get max efficiency out of it. Your system should draw 250-300 max.....
Corsair has a nice picture of the efficiency of PSU's, not quite accurate but gives you the right idea of why a half loaded psu saves you power
A test done on SPCR
the 250-300watt zone is perfect on this psu.....well near perfect for a machine with your configuration....you may even be under 250....if your not over clocking and depending on other hardware like HDD's....but from 200-300 this thing is perfect for your system...
With you budget....hmmm lets see
Seasonic S12II 430W - 30 Amps
Antec Earthwatts 430W - 30 Amps on the 12 volt rail(s) - on sale often
Corsair CMPSU-450VX - 33 Amps on the 12 volt rail
OCZ StealthXStream OCZ500SXS - They are unclear.... 30+ they have all the voltages rail combine.....so i assume the less 5 and 3.3 you use the more 12 you get....up to a point....
Zippy HG2-6400P - 12V @ 30 Amps on the 12 volt rail
the top 3 are all Seasonics.... Either way there are lots of PSU's around just make sure you get enough on the 12 volts rail,
I am more brave with my own stuff....
E6600 + X1900XT(similar power to your system) on a 380 watt antec with 18 amps
