Confusion about 12v rails

[Delta]

I looked into getting the Corsair HX520W, it is $135 here in Canada. The store is NCIX and is 10 min drive. So I can pick them up with out shipping. I also see the Zippy GSM-6600P (G1) 600W, was reviewed a few days ago, its only $150. Is the Zippy the one to go for another $15. The Corsair HX620W is $189 !

Not sure what I should get now! any help? .. I see the Zippy has better regulation, but a smaller fan. 600watts for another $15 !.

NCIX only has two 600W Zippys in stock, however that would be the one I'd go for. However, if you like the idea of silence or modularity, the Zippy isn't so much better in build quality I'd try to talk you out of the Corsair.

The Zippy has better reg, but the Corsair is more efficient and quiter and modular. There's no side by side comparison.

I would go with the Corsair, however either will be fine.

Woah, you live near ncix? That's either vancouver or burnaby! Or i think Langley.

I live about 15 minutes away from ncix richmond.

Thanks for the input! I never knew finding the right PSU would be so hard . I'm going to try and get the Zippy, if they still have stock. If not ill grab the the Corsair. ITs time to finish this build.

Oh yeah, The Langley store is the one I live 10 mins away.

Thanks again!
