Seasonic M12II 520 or Seasonic X-650? - Page 2

post #11 of 21
Thread Starter 
Thanks for all the replies!

Due to wattage overkill of the PSUs above and the huge $$$ savings of the following option, I think I'm going to pull a complete 180 on modularity and go for the SeaSonic S12II 380B 380W. It's about $65US shipped. Fully non-mod, but still a good SeaSonic design (it's on the Reco'd PSUs sticky). I'd love the super-handiness and aesthetic of full modularity, but I currently agree it's not worth it right now to pay the premium it demands given my usage needs.

One question I now have is would you recommend I pay $12 more and get the S12II 430B for its extra connections (2 more SATA; 1 EPS12V (8P) and 1 PCI-E (8P/6P) where the 380 has neither of those)? SeaSonic's series specsheet PDF here (connector comparison chart is at the bottom).

Also, the 380 would still power my proposed 400-600MHz CPU OC and an HD5670 comfortably, right? (And I could use the savings to buy a decent AM CPU cooler!)

Thanks!

Yes. The X-650 is a newer, more-efficient design and rated 80 Plus Gold, while the M12II is an older design and is rated 80 Plus Bronze.

Actually I think the M12II Bronze platform came out a month or two after X. But it is targeted to a lower-end market.

Ah. I must have misremembered, misread, or misunderstood something somewhere during all my research. Thanks for clarifying, and it is an honor to have you reply to my post.

Thanks.

I just installed my X-650 a few hours ago and I'm loving it. I now have some upgrade/overclocking breathing room... and if you've read any reviews on the X series, it's one of the best out there.

If you want a cheap PSU with low wattage, just keep in mind you won't have much headroom for any upgrades or overclock fun. I think throwing a 5670 and that overclock would be kind of pushing it with the 380w (I'm not the expert on this, by any means).

The extra SATA cables would be nice on the 430w, but I don't think having extra PCI cables would be too useful to you and your computer building future, as you seem to be interested in spending your money elsewhere, and you said you likely wouldn't be buying a graphics card that would utilize them (5670 doesn't use connectors, AFAIK).

I'm probably (re)stating the obvious, but really, you can't go wrong with any of the PSU choices you listed, unless you start wanting to upgrade your machine.

330w IS a bit cramped, but there is still room for upgrades. If he wanted to run it near the limit in furmark he could probably squeeze in an OC 5870 or something of the like. Anyways, by the time he wants to upgrade again anyways I'm sure there will be more powerful and efficient cards for his system.

Enjoy your shiny new PSU by the way.

Wasn't even aware there was a new X series released... but I believe it's a bit out of the OP's price range at ~$167 shipped. It's likely just a renamed/rerated X-650.

Thank you, lolreject.

With 330W, I think you would be right, but I was talking about the 380W version, which I'm pretty sure is good enough. I put my sig rig info into the Outervision PSU calculator, added a 700MHz OC with a .15V overvolt, two extra SATA HDDs for a total of four, a Radeon HD 5670 and an extra 120mm fan, and a generic PCI card to fill in for if I reinstall my PCI WiFi adapter. Recommended PSU wattage was 302W. (Screenshot below.)

I'm pretty sure this calc is the best online and still generally overestimates real-world needs, so I think 380W should give me plenty of room for my current needs. I even plugged in 4 DIMMS of DDR3, the 3.3GHz i5-2500 SB with a 500MHz OC and .15V overvolt, and the recommendation was 338W. I think my goals are modest enough to be powered by this 380W SeaSonic S12II though the extra SATA connectors for $12 tempt me toward the 430W.

If I'm wrong, I'd definitely like to know ASAP, though I expect to order this PSU in the next one to two weeks, so it's not a total rush.

Thanks to all who've replied so far!

Yep, definitely out of the price range. $130 was stretching it, and I think I only got there because of the hype of reading too many articles and reviews in too little time. SeaSonic's X-Series is the cream of the current crop, but my power needs are little and the extra cash will be nice.

If I were building something even a bit hardcore-ish now, the X-Series would be my go-to PSU and I'd plunk down the $130 for the reputation, aesthetics, ease of use, and performance. But I think the S12II series is fine for my current needs. And both series have the same warranty length in the U.S., I think, so no loss there either.
