The X-750. Better built, more efficient, quieter, etc.

You probably can't go wrong with any of those so I would just pick the cheapest one.

Yes but y does he need a hundred watts more?!

So why not go with the by fare quietest and most efficient Unit on the Market?

Efficiency and noise usually go hand in hand.
Only a really efficient PSU can be really quiet cause it needs to be dispatched.

And what's wrong with the voltage regulation and ripple supression of the Seasonic unit?
I don't see any point against the Seasonic X750 except for the price.

But also: Why 100W more??

PS: here in Germany the 850W Revolution starts at 212,30 (including VAT, excluding shipping), the 750W Seasonic X750 is about 200 and the 650W at about 180.

Because it's not very cheap but aside from that it's by far the best unit on the market in every way!

But you should consider the x-650 as well or do you really need so much power? (Crossfire/SLI with 3 cards, dual CPU?)

I don't know why he would need 100W more...he didn't answer my question when I asked what he was running.

Why would you be comparing a 750W unit to 3 850W units to begin with? Other than price.

If all he needed was 750W, he could get the HX750 or M12D 750W for $50 less.

Those are both plenty efficient...and deferring to your "ears" the M12D is plenty quiet enough.

If price doesn't matter then the X-750 is the right choice. If you are trying to be frugal, I don't see why the M12D or HX 750W units don't perform well enough for 99.999% of users.

i was just wondering
the thread compare m12d-850 and hx850
so i add more PSU to see if there any change to the majority choices

because there no 850watt from x series, i add 750watt (seasonic x750)
i'm not planning to buy new PSU
just curious, from that list, which PSU you guys gonna choose

in my place md12d-850 has same price as x750,
maybe some people will sacrifice 100watts for feature in x series

Most "750W" PSUs are rated for 60A on the 12V. The X750 is rated for 62A. Heck, the Antec TP-850 is rated at 64A. If I didn't need the extra 8A the X750 would be my choice for sure.

Choosing between the HX850, TX950, and M12D-850. They're all very good, so you can't really go wrong. I'd choose the HX850.

Why? Well, in reviews the HX850 has the longest warranty and performed slightly better than the other two, though there's reason to believe the M12D has improved since it was reviewed. The TX950 lacks modular cabling and it's performance isn't quite up to the level of the other two, so unless you need the extra power capacity either of the 850W units would be a better choice.

If I recall correctly the list of "best" PSU's at the moment consists of:

Antec Signature 650/850
Antec CP850
Corsair HX 750/850
PCP&C Silencer 910
XFX 850
Seasonic X 650/750

Plus maybe the Seasonic M12D. The M12D is known to have been tweaked since it was reviewed, and the PCP&C and XFX units on my list both use the M12D platform. The Enermax Revolution 85+ series isn't quite as good as the above units, but deserves an honourable mention. Arguably the Impervio built Silverstones, various 1KW+ Enhance built units, and the rest of the Corsair HX line also deserve honourable mentions.

The Corsair TX series and Antec True Power New perform almost as well as the above but are generally somewhat less expensive at a given power level.

I'll buy a X650 and add those missing secondary caps myself, then it'll become a X750.
