My original PSU was failing and a good replacement was needed but as I am relatively inexperienced in major work on any PC I was a little wary as to what to buy. After a fair amount of investigation, which included asking for advice on a site I use, I chose to buy a Corsair unit. Examination of price showed the 600W unit to be little more expensive than its smaller, 400W companion; as a result I chose the larger unit as I considered the less load it saw the better/longer/cooler it should function.
Initially there was a long delivery time quoted which I accepted, but in true Amazon style a much improved delivery date was provided within a day or two and the unit despatched quickly after that.
On receipt it was well packed being in the original manufacturers sealed box which was packed inside a standard Amazon box padded out with paper.
I knew the unit was not identical in its cabling to the PSU to be replaced, but the stiffness of the cable looms surprised me a little. The relatively small distances between the Molex connectors also caused a little difficulty which was overcome by using extensions to them. The cabling is designed for a more modern PC than that to which it was was fitted so this is not considered unreasonable.
The unit is supplied with fixing screws and cable ties which is very handy given the number of unused looms I now have - again useful in a newer PC than mine.
When fired up the unit worked as advertised; the fact I could barely hear it after the original was a real pleasure. I am happy to say that I believe I made the right choice in selecting a premium unit over a cheaper (as previously fitted from new to my PC) or unbranded item.
