So I am looking for a new PSU as I will be upgrading my graphics card. I bought my PC pre-built and at the time I though a 185w PSU would be fine. However looking around at some graphics cards they all recommend at least a 400-500w PSU. I am just wondering if anyone knows any decent ones. I'm looking to spend £20 - £40, and don't want to go too cheap or too expensive. If I go for a cheap one, there's high chances that it might blow out within a few months, and I certainly don't want that happening. I am looking to get a GTX 960, not sure which model though. I believe they need about a 400w-500w PSU. I have heard that the R9 280 are better (they are cheaper too), is that true? I also believe that the R9 300 series is going to be released/announced soon, should I wait for that as that might put a dent in the prices of graphics cards? For the graphics card I am looking at spending £100 - £150, does anyone recommend one other than the ones listed here for the price? Many Thanks, Dan.
