Antec Power supplies question.

[Jgtdragon]

What is the difference between Antec True430 ATX 430 watts p.s and Antec SL450 ATX 450 watts p.s ? I noticed True430 is more expensive. Both has Dual fans and Thermal Controlled Variable Speed Fan & Case Fans .

This is a good question. I've been wondering this too. I need a new power supply and I want to make sure I buy a quiet one.

i believe that the true power has stronger 5 and 12 volt rails due to load balancing

the regular antecs don't have the load balance

according to the literature on antec's site, the truepowers have:

dedicated output circuits for 3.3V, 5V and 12V lines.
voltage feedback detection, and tighter performance tolerances.
antec low noise technology
two double ball bearing fans
gold plated power connectors
nylon sleeving on the main power cables.

The main reason for the higher price is the dual circuits providing power the +3.3v and +5.0v/+12.0v rails. Conventional PSUs use a shared circuit for both outputs. This is why when shopping for a PSU, it's good to look at the "combined" output that PSU is capable of. Usually, the higher, the better. Not because of sheer output volume, but rather that there's enough of an overhead ceiling that if one rails "steals" too much from another, it won't cause instability with the system.

The TruPower series does away with this old method and regulate each output independently. In theory, this should provide much greater stability, power efficiency, and consistency of output. As far as I know, the TruPowers are the only consumer level PSUs uses this system.
