AC110V/220V to DC12V 40A 480W Switching Power Supply With Fan Size 215*115*50mm
A part of the review has been auto-translated.
This unit works well. Note that the fan is NOT regulated (even it is written on the case !) . It runs full speed all over the time. There is NO fan speed control by temperature (no circuit built, in fact the fan is direct on the 12Vdc output). This makes fan noise a bit loud, full speed even with no charge. Add of a temp fan control might be a serious plus to improve this product. The 12V output can be fine adjusted if needed. Robust construction, and good rate price/quality (especially at -51% of the regular price) .
Très bien mais attention livré sans câbles. La tension peut être ajusté de 10.5 à 16v

On the power supply's house has a little bit damage. But works it normally.
I got this to get my led strip lights going again that came with a 5 amp power supply. When I got them connected up to this power supply, the lights would some times flicker. When I connected my other set of led strip lights that flickering problem went away. My guess is that this power supply doesn't like being lightly loaded and a protection circuit kicked in. The cooling fan goes in to warp speed when I turn it on after it has been off for a while, it does settle down shortly after. As you can see in the pictures there is damage, but nothing important was broken.
It comes with a very strong smell and so I left it outside.
Out ou order... fan is break inside and spin move!
The power supply is working fine, but the product came having been bent at the weak end which is a shipping or storage problem.
works well. fan always on though
I haven’t tried it yet.
