i currently have the rig in my sig. im trying to mkae it quieter so im going to invest in some stuff. the ocz is great i just dont like the cables in my case so.....im going to get a new PSU and put the ocz in a ftp server (should get the job done :) ) now i need a psu so i can upgrade to a min of 2 gigs tuner card and a bunch of HDDs and opticals. i am thinking about getting the s12-600w i dont really want to spend anymore then that so waht would you sugest? thanks for all the help

God why is everyone so stuck up SeaSonic's A$$ these days? Sure they're good, but there are other awesome PSUs which can be had for much less money.

I'd look at Enermax and OCZ before I went straight to SeaSonic, mainly because of better bang for the buck. I'm also still leery of dual rails due to the low amperage.


Also, it's not like that rig in his signature needs 600W. A quality 480-500W should give him PLENTY of cushion.

OCZ before Seasonic because of better bang for the buck? OCZ is overpriced.

I would take Seasonic over Enermax because i've seen some concerns over reliability.

as it stands, Fortron and Seasonic are the two top psu makers. Fortron for one of the most reliable, efficient and decently priced power supplies. very dependable

Seasonic for saving a few bucks on your energy bill and really quiet.

pc power and cooling is up there but out of reach for most of us

The price difference between the 500w and 600w S12 models isn't much at all, so for the "bang for your buck" mentality, why not just get the 600? As for how much juice the S12-600 can deliver, it can operate my workstation just fine.

PS. Bringing up OCZ while stating an arguement about price point is akin to shooting yourself in the foot.

ocz/seasonic are both overpriced... if you want true performance without all the hype but at the cost of looks...

http://store.xxera.net/emhp50eps12v.html

Zippy/Emac are server class PSUs so make sure you order the 20 + 4 pin one. Even if you have a 24 pin mobo, you can still plug in the 20 pins and it will work. Read reviews on the psus if you want but its better specs than Antec, voltage is extremely stable. But thats just me...it really doesnt look good...

Actually the Zippy HG2-6400P would cover most systems including the OP/s with plenty of headroom. At the same site linked above for $75. Even the 350 Watt unit for $69. would be more than adequate. XXera Link -- Zippy Link . If it were me, I'd get the one with EPS12V - and 8-pin (4x4) CPU power connector as long as there is clearance off the ends of the connectors on my mobo. The Zippys have all the good stuff too - active Power Factor Correction and full range line voltage (+/- 1% regulation!) - 90-240VAC, ~50-60Hz. (the 300W has 22A@12V, the 350W has 26A and the 400W has 30A!!!)
. IOW, 24-pin PSU connector will fit in 20-pin mobo connector but 4 pins do hang off one end (the end opposite the 3.3v. wires). The 4x4 (4 ground wires x 4 12V wires) would also hang off the right side (looking at tha latch side) of the 2x2 connector. The connectors will only go in one way so you don't have to worry about that. That way you will be ready for any future upgrade. But you can get it with the 20/4 pin connectors if you want. Zippys are great and very quiet even though they use just the one 80mm fan. I had a couple of HP2-6460s here and they were nice and quiet at normal temps. Look at how open the fan grille is!
. I've not seen Zippys at this low a price before except for the rare clearance of old stock. Thanks for the XXera link FS!

You can't get totally quiet w/o going fanless - do you have $200.-300.? And a lot of them that are too quiet run their internal temps too high - I don't like that. I've done some PSU mods because the fans ran too low (too hot for me) - I either bypassed the thermal sensor in the PSU and ran the ran on straight 12 or brought the fan lead out to a manual fan controller. I had to put my ear down to the Zippy 6460s I had here to hear them. But my ears aren't the greatest any more.
. Besides, Zippys have nice nickel plated cases (good for RFI/EMI rejection). You don't see that much any more.

you're talking about different quality levels of power supply. Seasonic is a whole notch above your Noisetaker/Modstream. It competes with PC Power Cooling and Zippy, etc.

Seasonic is QUIET and STABLE.

Sure you can argue that 480W is enough, but we're talking about RAILS here. I can't believe everyone just figures they only need 300W tops and get a piece of crap PSU. No! You want to look at rails. I didnt' buy the 600W version because I needed 600W. I bought it cuz itw as on sale for less than the 500W normally retails (500W was not on sale).

Seasonic's rails aren't exactly the strongest, and it takes about 600W to make the 12V rails really powerful (18A per rail I believe).

Patriot should work with a DFI board. Just none of the cheap corsair crap.

18A per rail ain't cuttin' it in my book. You won't see me on a dual rail PSU until they're pushing 20A per 12v, minimum. I still recommend people just look for a good single 12v @ 28A or more these days. With modern high end graphics cards chewing power from the 12v, I'd not be willing to go low on the amps there.

In reality, he'll probably be fine, but I'm just psychotic about that.


Consequently, this Tagan is the model I'm considering upgrading around come this christmas. Supposedly a 480W supply, but works out at around 600W with 30A on the 12v when the 12v rails are combined, and over 800W (!) when the 12v rails are left seperate.

Being that Tagan is well known to be a respectable PSU manufacturer and this thing is stickered so much lower than what the math says, I'm betting it's a beast in disguise.

I found a review of the zippy 6400 at HG2-6400P and a review of the HP2-6460 and PSL-6701 at Madshrimps. There are others out there and could be under Zippy or Emacs or both (Zippy is the company, Emacs is their PSU brand name).
. I can't imagine that there isn't a review or two of Zippy at Tom's too (I found only the 600W unit in their Feb. 2005 PSU comparo. Their PSU reviews are about as technically proficient as you can find even though I don't care for Tom's in general...

.bh.

p.s. Zippys are still made in Taiwan and use mainly Sanyo Denki dual ball fans.

the spec sheet on the Tagan PSU states that even though the both 12V lines are 20A, then the combined load must not exceed 30A. And the combined load of 3.3V+5V+12V must not exceed 460W.

The seasonic S-12 600W can handle a max of 18A on each 12V rail, but can handle 36A combined.

nice link but it even says it right on the side of the unit in neweggs pic.

if i were to spend the money i'd get one of the s12. short of that i'd get another tpII as all four i have are unbelievably tight, plenty powerful and quiet as well.

Yeah, but amps are not additive, so frankly leaving the Tagan as a combined 30A 12v rail is going to be better for current input in most situations that leaving it as two seperate 20A 12v rails, but frankly I just like the flexibility of being able to do either. I'm not going through cable hell trying split up my 12v rails evenly.

Hell, most modern video cards shouldn't even be attached to a 12v rail that's less than 17A, so putting them on one that's 18A is pushing the line in my opinion.


I haven't seen where the combined load of the 12v rails is not supposed to exceed 30A? I do see wherein when you *combine* the 12v rails into a single 30A rail, that that would be the limit, but I don't see anything in that PDF or at newegg specifically stating that seperate rails are limited to 15A each?

That's the problem with dual rail PSUs these days - they're slim pickins for current for high end graphics, and even worse if you end up going SLI. Just not enough amps, period. Like you said....wattage doesn't matter as much as amperage these days.


The wattage rating is conservative, but that's the case for most quality PSU manufacturers. Math out the Seasonic S12-500 and you'll see that it should be pushing 645W, but is only rated for 500. Reason? PSU efficiency drops as they get warmer (although Seasonic is better about this than most :D ), and honest manufacturers reflect that in their numbers. A well cooled case shouldn't have to worry much about it though. Again, the Tagan works out to around 600-some watts as well (with the combined 30A 12v rail) and is rated at 480. Less efficient than Seasonic? Probably, and thus the lower rating.


Long story short, I'm not worried about that Tagan's ability to push on either the seperate or combined 12v rail. I have a feeling when combined it's limited to 30A as that's probably the maxmimum that the connector switch linking the two rails can safely take. Leaving them seperate, I have no doubts about their ability to go to 20A each.
