Antec NeoHE Modular 550w PSU
Published: 1st May 2006 | Source: Antec UK | Price: |Testing
The Antec Neo HE is the first unit to pass through the new and improved OC3D PSU Stress Tester. The tester is capable of placing loads on the following rails:
+3.3v - 20a Load
+5.0v - 20a Load
+12v1 - 10a Load
+12v2 - 10a Load
+12v3 - 10a Load
+12v4 - 10a Load
(or 40a on a single +12v rail)
The results are collected from a Mastech MAS-345 Multimeter which logs its readings via RS232 to a PC.
The load voltages will be taken after 15 minutes on the PSU Tester - any longer than this becomes a slight problem as the Stress Tester's Resistors hit around 150°c each (and there's 8 of them!).
Either i'm going deaf or this unit is totally silent! During testing i was forced to place my hand at the back of the unit to see if the fan was pushing air through several times. Only when all of the rails were tested together (total 70a load) did the unit emit a silent whisper.
This is where the 'High Efficiency' of the unit comes in to play. The unit managed to remain cool, and keep the fan speeds low under high load, which means that very little energy was turned into heat during the conversion from AC to DC voltage.
