The Adda AD1212MS-A71GL is a 120mm Low Voltage Axial Fan which is an oil impregnanted sleeve bearing unit. It requires 4.08 Watt of power and operates at up to 2,050 rpm for a 80.5 CFM rated airflow capacity. The company rate the fan as producing a maximum output of 38dB, however under normal circumstances it should generate significantly less.
The internal design is very clean with massive ‘L-Shaped' heatsinks spreading across the full diameter of the PCB. These sinks are directly under the airflow of the fan and will ensure maximum cooling efficiency.
This is an Active PFC design which offers full protection for OVP/UVP/OCP/OPP/OTP and SCP. The single rail design in this particular unit delivers up to 48A on the 12V. The Hybrid Heatsink is a switching mofset design and the capacitors throughout are all Japanese made, high quality units. The VRM control transfers to 5V and 3.3V.
The design also places the IC close to the transformers which are required to create the high efficiency ratings. It complies with the latest Intel ATC 12V V2.3 standard and there is a double layer EMI filter to help reduce noise.
The cabling is fully sleeved inside the unit and is rubber protected to ensure no wires will get damaged caused by abrasion against the metal chassis.
That looks stunning, love the gold. its not like the enermax colour which was blinding,. its more a bronze/gold. duller. tech results are great too.
I think this one looks even nicer than the corsair AX products. same kind of font usage as was pointed out.
92% at mid way load is a fantastic result. shame it gets louder over 80% load, but its to be expected really. I think this would make for a marvellous high end media center PSU. inaudible. but I wonder if the 750W corsair would be just as good as the fan wont spin at all under normal circumstances.
Cable management looks great. internal L shaped heatsink design is an interesting concept and seems to make sense as it would direct the heat outwards.
Good review, thanks for the testing. never found a good review of this one.
Very nice hardware indeed. I think its a little overpriced though.
Its not overpriced at all. you need to look past the wattage rating to the 80 plus gold certification. Thats what costs them, to get the output to these standards. 99 quid isnt half bad.
Brought one of these along with a GTX 460, I’ve had nothing but problems with it unfortunately, the pc constantly locks up with it and isn’t that quiet even running simple 2d. I’d have thought the rated 48A rail would be more than enough to run a single GTX 460 .
Why are you certain it is the PSU ? have you tested the same system with another supply?
Its pretty obvious this psu was the problem in my case when an alternative 600w psu was tested and the system became stable and quiet .
It runs ok with the 8500GT but the GTX 460 gave it major problems
