An obsolete design is an obsolete design. That said it still works, but isnt optimal...and that's the point when I brought it up. A psu was suggested that least two reputable reviewers didnt rate high and doesnt fall into what many would define as a "good" psu. Am I splitting hairs? It's possible... I know it will work. It isnt powmax, apevia, diablotek, etc... I get that. There are just higher quality units passing more difficult testing out there for the same money or less. We've got a decent budget to work with and can get the OP something better is the point.
Now... for my money...Corsair 650W VS will do the job. It isn't pretty, but is more efficient and also isn't lipstick on a pig like the N1.
Anyway, OP, you've seen an eyeful in this thread, lol... hopefully you learned something about PSUs. There are great choices here listed by dirrtyf and SSS that will fit your budget and a better choice over that N1.
