QTechnology QT-03400G power supply
We have looked at a Qtechnology PSU and my reviewer gave it a very good rating so I got kind of curious and wanted to check one out also.
I have 400W PSU with a 120 mm blue led fan on the bottom so it will be interesting to see how this can perform against some competitors.
The power supply runs on two separate 12V rails and the specifications seem very good so this will be interesting.

The product was very well packed and included an adapter for 20 pin motherboards if needed.
On the side of the box you can see the features and specifications and on the front you can see a part of the power supply itself.

Included with the power supply we have a power cable, sticker, manual and some screw. The power supply itself is a very nice silver color but it's also available in black
if you prefer that. When you feel it you get a nice feeling of quality. On the bottom as said before the have mounted the cooling fan which in this case is a 120 mm fan to
remove the loud fans but still be able to push out some air to cool the power supply of. In this case its a led fan but the leds do not heat up enough to heat the power supply up.

The back of the power supply is equipped with a grill so the hot air can be pushed out through the back also. Here you also have the power connector mounted along with the on/off button for the psu.
Two separate 12V rails with 14 and 15A each is very good and it will be interesting to see what kind of readings we can get with our multimeter.

Four molex and four SATA connectors are included to power up most of your computer. Then we also have the ATX, PCI-E and floppy connectors of course.
Overall sound and noise wise this is a very quiet PSU I cannot hear of if I dont put my ear close to the power supply.
