ASUS Atlas A-45GA 450 W Power Supply Review
Conclusions
Contents
The ASUS Atlas A-45GA 450 W can’t deliver its labeled power. The maximum we could pull from it was 365 W.
On the other hand, voltage regulation was superb, with all voltages closer to their nominal values than required (3% regulation) and with low noise/ripple levels.
Even if this power supply was labeled with its real wattage we wouldn’t be able to recommend it, because its efficiency stayed below 80% all the time.
If you have this power supply you don’t need to worry, because it doesn’t offer any risk of use: as explained, voltages and noise/ripple levels were always within specs, and this unit will shut down if you try to pull more than it is capable of delivering.
I bought this power supply in 2009 and it never let me down. Will have to look for a more powerful one though, as I am contemplating buying a new graphics card
