Summary: Installation was not difficult but the average person may have a problem. As of now it is better and quieter than the one I had. I had to replace the old one because there was not enough power.I am satisfied with the noise level. I am well pleased.
Summary: great power supply, it was easy to install just a plug play type of install. It had a lot of extra plugs for other computors , I just tied them out of the way. My computor has been working great ever sense.
Summary: I had to make one adjustment with plier to my HP a1419h case and it fit. The power cord plug in location was a little off from the original (a little bending of the case allowed it to fit). Easy to connect. It has been working well for a few weeks now. Replaced a Bestec 300w unit with this 400w.
Summary: I ordered the power supply and was excited to receive it. And then, right a way I was disappointed - it was damaged. There was a dent on one side, a plastic ring around the electric wires so it won't be damaged from metal edges of the power supply - broken, power connector 20+4 had a pin missing - there wasn't even wire going to that place and it should be. As result, it didn't work when I installed it in my computer. So, I received it yesterday and returning today.
Summary: Rite, you don't have to spent much to get this power supply. .................................................................. The wires that are in side of this thing are very light gauge, thinner than the ones in my 250 w power supply. That would explain the fact that there are very few plugs for extras. CoolMax really dose not wont you to use all 400 w. Only 1 Peripheral power x 4 4-pin. Your computer will need more than that if you plan on any kind of upgrade.
