FSP Raider 550w

Power supply units



A lot of companies are in the PSU game, which is why it’s important to make sure the one you’re buying is a good one. Or at least, one that won’t damage your system. Because that can happen with a cheap unit and while here at XSR we might not have all the fancy testing facilities of the bigger boys, we can make sure that yours won’t overload your components at the first opportunity.

So today I’m looking at the FSP Raider, the 550w baby version. Let’s throw it into our test setup and see how it gets on.

The packaging is pretty standard. This is far from a premium unit, but not everyone wants £10 worth of packaging around their expensive product, they want the product and that’s it.

Nice to see a UK plug for once. So often these things come with an EU kettle lead and you have to go and buy a converter.
