M12II 620 or X650?

post #1 of 19
Thread Starter 
My build will be the same in my sig, with the addition of a 2nd 5770 in xfire.
Do I really NEED the X650, or can get away with the cheaper, but still quality M12II?
The "quiet factor" isn't really a big deal, as my rig is fairly loud anyway.

Either unit is good, X650 is just a little more icing on your cake.

5770 is a 110w GPU. Either one has plenty of power. If you don't need a full modular, go for M12II 620.

Although I did just see the egg has the Corsair 750TX on sale right now for roughly the same as the M12II...
Although I have heard that Corsair has been slipping on the newer PSU's?

TX750 is outdated. The M12II is the better PSU.

Well, lets pretend for a moment that cutting edge PSU tech is somewhat beyond me. Is "outdated" the same as "worse"? Or does it just mean that the SeaSonic is made in a newer way? And is the TX750 one of the rebranded SeaSonic models made for Corsair?
I'm not trying to argue here, just looking at different deals. With the TX750 I would probably be getting more PSU than I currently need, but I would also be getting a pretty fair deal from what I can see. I'm seeing pretty good reviews for both all over the place.

Edit; I found out it's not a rebranded SeaSonic.

Actually, after some searching I found the Kingwin LAZER 850 for $119.
It's more PSU than I need, but it's got good reviews and it's modular, and I actually LIKE bright LEDs.
Edit: There is really no way that this has a combined HUNDRED AND FORTY SIX AMPS on the 12v rails...is there?
OOps, saw it has 68.

Outdated in this case means that efficiency and electrical performance (specifically ripple) are way behind the curve in comparison to newer units that occupy similar market positions, and this is not reflected in the unit's typical pricing.

The Corsair TX750 is a CWT PSH that has very good voltage regulation, but mediocre ripple (90-110mV on the +12V, 120mV is the max allowed) and just squeaks by 80PLUS. There are new versions based on PSHII which improve ripple suppression, but we have no idea what companies are selling which version.

The SeaSonic M12II Bronze 620W is SeaSonic's second iteration of the S12II platform, with +12V ripple in the 40mV range, good voltage regulation (if you don't crossload it, ie don't use it to power a Pentium III), and clears 80PLUS Bronze with room to spare. Plus it's modular, which makes cable management easier.

It's just a better power supply.

Thanks for the link, but I really don't like MIR, and especially not ones for that amount of money.
I ordered the Kingwin, and by all accounts, it's a very decent PSU. Probably not SeaSonic good, but better than I need for now.
Thanks for all the information and suggestions everybody!
