Beware faulty units!
on 12 December 2014
I bought this power supply to replace one that had completly died on me. I saw the hundreds of reviews with 4 to 5 stars and as usual I ignored the 1 and 2 star ones - saying "these are probably one offs". Little did I know that I was about to become one of those "one offs".
My intial thoughts when I first took this out is damn, I made a mistake. I thought I was buying the semi-modular model without realising I had to select it from a drop down. A clumsy mistake. I will blame the fact that I did this on my phone (as I said, the power supply on my computer was dead!).
But what a mistake it was. Compared with my previous one, there were so many wires! Too many in fact. I appreciated some of the extra ones as I had a couple of converters with the existing psu that I was able to remove, but there were then far too many!
The other problem was that the way that my computer is set up, the orientation of the SATA power cables were the wrong way, and so I have had to twist it awkwardly for all 3 of my SATA devices. I am prepared to say that this is just my computer and not everyone will have this problem. But part of me thinks that it isn't. It is standard setup to have SATA devices at the front and the PSU at the back, and it is standard to have them all the right way up!
Anyway, I pressed on. I managed to plug everything in, and did my best to tidy the plenty of other cables that there were left over. 1 positive is that they provided some cable ties albeit small ones, but still, I found them useful so well done for that.
Once everything was plugged in, I found my first problem. The switch on the back of the PSU was faulty. When I tried to click it OFF, it wouldn't fully press into the off position and then would - bounce(?) - back into the ON position. I thought this was odd, but I was able to look past it. To be honest, I don't really use this switch apart from when opening up the computer and since it was stuck in the ON position which is where I want it to be 99% of the time, this was fine. But still, this is a fault.
Moving on, everything worked. But after a couple of weeks, the power was cutting out again. The behaviour was strange. It would cut out and then the computer would try and switch it self on again but was cutting out before it could, on a loop. I would compare it to trying to start a car on a flat battery.
I initially didn't suspect the power supply at this point. I thought, there is no way it could be this brand new top seller on Amazon. Given that this all started with power problems, I suspected that this was something else. Nevetheless, I thought this behavious was unusual.
Sometimes, after a day or so, it would work fine for a week, before repeating the symptons.
When it was working, I noticed in the BIOS that the 3.3V cable was showing that it fluctuating between 2.7V to 3.0V and was coloured red.
After 3 and months of this behaviour coming and going, I decided that the 3.3V being too low was not good.
I came back onto the product page and decided to read the 2 star reviews to see if they had similar problems. And they did! They too had problems with the supply out of the box!
Amazon has a 30 day return policy and this was way past that, but I spoke to them and they arranged a replacement unit.
I installed this unit last night. The first thing I noticed was that the ON/OFF switch on the back worked fine! I was now able to press it OFF and it would stay there! I have also looked at the voltages and they all seem stable - for now.
I will now monitor over the coming months. I hope that I had just had 1 faulty unit and this one will work fine. I just felt everyone should see this!
I have rated 3 stars because when it works, it is a good PSU. But there are too many cables and it seems their quality control process needs to be looked at. Kudos to Amazon for the replacement!
