This is basically a Seasonic PSU branded as XFX. Seasonic are one of the biggest names in PSUs and this model has rave reviews all over the internet that speak for themselves. I just want to add my own personal observations: 1. I ordered mine from Novatech and it came with an AMERICAN POWER CORD which is useless in this country. No biggie - most folks will have a standard IEC cable("Kettle Lead") kicking about somewhere but if you don't, chuck one in the shopping basket to avoid inconvenience later. 2. There really are a lot of cables - if you're fastidious about cable tidiness you won't be happy - go for a modular one. Likewise you'll either need a lot of space behind the PSU to cable tie up all the unused cables...or have a good place to route/cram them. As the other reviewer says though, its a small price to pay for what you get. This thing is reassuringly heavy and comes with the Seasonic name under the hood - recommended!

5/5 for what it is. Pros: It's a decent brand, and it works very well for my needs. (Core 2 Quad Q6600 & GeForce 560 ti) Cons: Obviously I can list numerous cons, that it won't work with the top power hungry graphics cards, it won't work with the medium power hungry graphics card in crossfire or SLI. It isn't modular, so the number of cables you have to find space for in your case seems insane. But you get what you pay for and for under £50, this is a bargain. One tip though, Novatech offer free delivery for over £50, so if you just want the PSU (currently £49.98), find the cheapest item on here and get free postage.
