Seasonic M12-600 vs Corsair 620HX?

[DerwenArtos12]

Hey guys,

Replacing my current Seasonic S12-600 for something a little more efficient and modular. Which of these two would you go for. Prices are similar. I know I don't need the full wattage ATM but, will be upgrading to C2D right after nehalem comes out and you're all trying to dump your 8400's and 8500's for cheap so you can get an integrated memory controller. Which of these two would you reccomend. I have personal experience with SeaSonic and like they're stuff but, the Corsair is so popular I thought i'd ask.

Thanks,
DA12

Didn't you 'moduralize' that PSU yourself ? The 520hx can be had for 90$ here btw: http://www.buy.com/prod/corsai...loc/101/203270716.html

No personal experience with, it got pretty good reviews, but is it worth the 30$ extra over the 520hx, from which we simply know it's quiet and pretty efficient ? Anyways, just making your choice a little harder with that link for a 'cheaper' 520hx, good luck with it

sure did, I should have the pics and stuff up here in a few. I just re-vamped my HTPC and found that a lot of the troubles I had been having were with my 6 year old antec 350w power supply trying to power up an A64X2, 8500GT, dual tuner cards, EMU 1212m, dual DVD-RW drives and 7 hard drives(6x500GB and 1x 320GB) so I'm going to throw my S12-600 into it since it should only run the PSU at 60% or so, therefore keep the efficiency up on a less than efficient PSU and get something new for my system that should be better compatible with my C2D set-up coming later on this year. Plus the modularizaion added about 1.5" to the case of the PSU and and almost an inch for the connectors; it just looked crowded up top and we can't have that on our demo system can we? Plus, I'm going to an externally powered chilled water set-up on my main rig so I'll be able to turn all the fans way down so quiet is sem-important, even though there's going to be an AC compressor running right under the computer anyways.

In case you weren't aware, the Corsair HX series are built by Seasonic and based on the M12 platform. The HX is quieter since it excludes the 60mm fan. They also come with a 5yr. warranty.

Besides the longer warranty on the Corsair, which I prefer over the Seasonic, these two statements may possibly sway you a bit:


From Corsair about the HX620:

Guaranteed to deliver rated specifications at 50ºC.

From Seasonic about the M12-600:

The rated power will reduce from 100% to 80% from 40°C to 50°C

http://www.seasonicusa.com/m12.htm




That about says it all for the two......I'd prefer the one that doesn't derate its output despite possibly being in an overly hot environment.

jonnyguru said that the seasonic-built corsairs are actually a little bit better built than seasonic's own units.

From a component selection standpoint.

The PCB and layout is the same.

Well, got two surprises there. Does corsair just not want to pay for the 80+ cert then?

Guess I'll get the corsair, thanks.

Not sure what the deal is there. They're listed as a company, so the big investment has been made. Submitting units after the fact is relatively cheap UNLESS they vary so greatly from the OEM that they can't get the "we relabeled another company's product" discount. The modular interface may have made those units so different that that may be the case, and then the charge to test a unit from scratch is as much as it is to just get your company listed.

In the grand scheme of things, I don't think it's that much money. The tooling to stamp your name into a housing costs more for goodness sake, and the product is efficient. But perhaps there is another reason....

Differernt power supplies test differently and provide different efficiency numbers depending on how the load is applied. Like a +12V load might be more efficient than a +5V load, etc. It could be that the WAY 80 Plus loaded the HX units, it didn't pass. Perhaps?

How do you figure? Think the 80 Plus should be free? They have to get funding somehow.

oh no, I don't disagree with them charging at all. I was blaming corsair which isn't entirely fair either, there are just very few third parties that give as good of performance data as 80 plus, anandtech or jonnyGURU so I have to find someone to blame right? It's the american way.

Remembering some reviews, the HX series was right on the border for 80plus anyways. I'm guessing it probably would pass, but is it worth doing so far after original release? I doubt they have any sales problems with the insanely good reputation the supplies have now. I think it'll make more sense for corsair to just obtain the cert for future products as they seem to be doing.

that is probably exactly right. I'm sure Corsair did a cost/benefit analasys and given the already strong sales and great reputation of the HX series it wouldn't have made fiscal sence to pay for a whole new test and certification on the power supply but, that doesn't mean I have to like it.

Hate to resurect dead threds but, thought i would make mention that I've a plate of crow for lunch later. Was on the egg this evening for something completely un-related and saw that all the Corsair PSU's now carry the 80 plus cert. I for one and quite glad they went ahead and got them if for no reason than to help boost sales on already strong selling and good power supplies.
