what brand is best?

[Dymblos]

Enhance, Forton or CWT

and between this psu
Thermaltake Toughpower 850w W131RU (Modular)
Zalman ZM850-HP
PC P&C 850w (the only bad in this, is the acustic!! 45-50dba in load = games)
i now this three PSU are excellent coz i read a lot of review and all they give the same veredict

but a review is for a few hours.. but what about all days?

Pretty much everything I said at Xtreme goes here too. My SG-850 has been running 24/7 for months now.

You can't speak as a whole, only for specific models. Latest CWT performs very well if they're not pushed beyond platform capability (some Xigmatek or Toughpower 850 push it a little), Enhance is very good too and FSP not so good.

From those three I'd choose...Antec Signature 850. :D
Otherwise Zalman would be my choice (I like silence).

LE: Hehe I've had a feeling of déjà vu. :D

This feels like a trolling thread to me. I'm locking it down.
