Antec power supply difference
- Thread starter Disarray
- Start date
To sum it up, it lives up to it's rating...it's true rating.
Lots of power supplies have the 3.3 and 5.0 volt on one circuit and the twelve on the other, where as the Antec True have a dedicated circuit for each of them.
Cheopo's say the they get x number of watts out of each of them, but they don't tell you that when one is getting strained the others ones get cut short, so in actual performance they don't give out the capacity of their rating.
Kind of like cheap amplifiers claim to put out 500 watts, but their RMS rating is only 80watts. Cheapo PSU manufactures are playing the same game.
I used to have an Enlight 350 running everything in my sig below. I kid you not, but I could hear the fan (Delta 7K) from my CPU HSF change pitch as it slowed down when the CPU came under full load. Put my Antec True 430 back in when it came back from RMA, and it stopped happening. Now if a fan can slow down cause of lack of current, what about all the other things like hard drives, etc.

Agreed. I wouldn't doubt the normal Antec line are fairly accurate and definitely reliable, but if you want to make sure, this is one of the ways to go.

w/ my 350 watt Antec (non-true) i can her a fan in my case slow down while a full load hits, kinda scarry

I found that even a 2% change in voltage can cause a very noticeable change in fan sound, and since birds and walruses sound the same to me, I wouldn't worry about it.
If all the rails can't be run at their maximum amps continuously and simultaneously, then the PSU has a combined power rating, only with TruePowers it's for all three main rails, while with other PSUs it's for the +3.3V and +5.0V alone. But oddly, the latter can be equal to both those rails running simultaneously at max amps, as it is with the 300W SmartPower (20A @ 3.3V + 30A @ 5.0V = 216W, virtually the same as the 220W combined power rating) and another 300W PSU I have.
