New SeaSonic X-Series Gold PSUs

X-Series; Fanless 400 & 460 watts
Fanless power supply has been around for many years but never one has lived up to the performance and quality requirements until now. The new Seasonic X-400 & X-460 fanless power supplies take advantage of the 80PLUS(R) Gold super high efficiency and low component count design to bring quality and performance to a whole new level.

X-Series; 560, 660, 760 & 850 watts
Versatility and balance best describes the mid range X series power supplies. These power supplies provide enough juice to run most systems on the market today. Manufactured with top-grade components and a Sanyo Denki fan coupled to Seasonic’s Hybrid Silent Fan control, these units will be the workhorse of your system, day in and day out.

X-Series; 1000 & 1200 watts
Power, is what the 850, 1000 & 1200 watts units are all about. For the serious PC enthusiasts with super power hungry systems, these units will run any system configuration you build. These top end X series power supplies provide more +12V DC output than any comparable competitors on the market today.

The New X Series broadens the original X series lineup to a full range of power outputs from 400 to 1200 watts and at the same time, maintains the Full Modular DC cables capability and all the superb features found on the original X series plus upgrades such as fanless functionality and upgraded DC-DC circuit design.

Nice, think I might go for one of those fanless 460Watts

Yep, passive 460W seems very interesting.

Damn! I bought this x-650 a little while back...400W would be much more appropriate...oh well, I can't imagine the efficiency curve will be hugely improved.

Finally! 1000 and 1200W - great! :up:

Cant wait for the 1000w to come out. Bit miffed that i just purchased an enermax rev 1250w
Fingers crossed for a release soon

Why is this thread getting no buzz but people are going crazy in the corsair PS thread. The very very best of Corsair PS, were made by seasonic.

A 1200W X series sounds crazy good. The x750 is universally the best 750w ps there is and a 1200W if they can carry the tradition, is going to be a great power supply too.

I'm not too sure what I should think of those fanless psus, I mean whats the point of getting rid of the fan in the psu if you then need a louder fan to get rid of the extra heat in the case?

Maybe because the corsair psus have good availability and low prices compared to Seasonic branded ones, anyway, I'm happy with my Seasonic psu, silent, built like a tank and doesn't have any problems with being used in a crunching rig.

:( I hate cable management. (*)
Will they release models with fixed cables?

(*) For me cable management is not useful at all.
1. more expensive
2. cables lying around and next time I change PC setups I don't know which cable belongs to whitch psu
3. an additional connector is a possible source for problems such as contact resistance

I guess you have to make sure you have positive pressure in the case.

In canada, thats not the case. Seasonics can be found just as easily as the corsair, and their 850W models is significantly cheaper than hx850W.

In small cases, especially where the psu mounts over the cpu, it's nice to be able to remove the psu without disturbing your cable routing.

Sooooo it has no fans and is covered with holes. These things are going to suck in so much dust. Please report in the first one that catches on fire please.

What will do all this sucking with no fan ?

A fan sucks in dust, yet no fan equals more dust. :nuts:

do you really think a user with 150$ for a 400/460w psu won't know about dust?

normally most intake fans are in the front....the psu would be a vent not an intake...

You have to use positive pressure of course, otherwise it will bring the heat and dust into the case.

Because the vents are shaped in such a way to act as a magnet for dust particles.

You have to remember with increased efficiency, there's less heat being made in the psu. Also, according to some of jonny guru's tests, efficiency actually goes up in his hotbox.

Seasonic X-560 560W Review
Seasonic comes to us again today with another model in the X Series lineup - the X-560. Like the other members of the family, this unit boasts 80 Plus Gold certification, full modularity, and a single 12V rail almost as powerful as the total rated capacity of the unit. It is also currently the lowest powered unit in the line that has a fan, with its 460W and 400W little brothers operating completely without a fan. Let's see how it does....

Negative air pressure has better cooling potential but sucks in a lot of dust and fibers. Swapping to positive air pressure helps keep dust out. Anyways, I do like the fanless designs. I'm far more enthused by the Seasonic lineup (especially X-650 and X-750's currently available). If I wanted a nice cheap quality Seasonic I'd look at the SS-750HT & SS-850HT (80 PLUS Silver and like $110-120 on Egg).

That fanless 460 watts will be my next PSU. I can't stand noise or fans any more. Xtreme silent will be my next project, 1DB is my goal :)

careful with some things, my old PSU sounded like a fax modem cause the GPU was drawing too much power

Single mainstream GPU around $150 - $200 will be fine.

So I already got a x-750 and it does a wonderful job for my current setup but I'm thinking that if I ever want to upgrade to dual 6970 (currently single 5970) I might be short on power, with the overclock and all. Finally there's a 1000w that's worth my time :D

The 450W Silverstone NightJar has been out for years and got very nice reviews....why all the interest in the passive models....what new do they bring to the table?

460-watts, fanless, 80-plus GOLD rated, fully modular....

That's what the interest is about. Nothing new... just lots of REALLY GOOD!!! :D

And what is wrong with let say 560w? :) Fanless most of the time and if you have a good case it will stay like that. This could apply to 400W/460W fanless model as if you don't have good air ventilation, you psu will heat more etc etc...
10-06-2010, 04:50 AM

Nothing wrong with these....they look great. It just seemed like maybe ppl thought this was the first time there was a decent fanless model (based on the 1st few posts).

Nothing wrong, indeed. That passive 460W model seems quite interesting. Should prove useful in HTPC etc..

i still dont understand the passive cooled power supply. maybe its because ive never really had a silent system, but i sure cant hear my psu's fan over any of the other fans in my system. i rather have the x 650 which gives me more power should i need it and is cheaper. thats just me though

Yeah your right electronics aren't prone to dust, PC cases among other things surely never collect dust :rolleyes: Walk into your local pc repair shop and ask how much duster they go through.

The case fans will fill the fanless PSU with dust if not configured properly.

A PSU with fan draws air from the case to the outside (= less dust in the PSU),
while a fanless PSU will act as a vent for all other case fans (= possibly more dust in the PSU, see below).

Now if you have more air coming out than going in, like more exhaust than intake, you'll get negative pressure in the case and the fanless PSU will act as an intake = fills with dust.

If you have more air going into the case than out you'll get positive pressure in the case, which pushes air in the case through the fanless PSU and to the outside.

Seasonic X-Series SS-460FL: 460 Watts of Fanless Power

Quote:

With a price of $160 online the Seasonic X-Series SS-460FL is as expensive as some previously tested 1000W power supplies. However, it offers the best performance we've seen and a fully modular connector panel. We've never seen a PSU that has no real weaknesses in our testing, and the worst thing we can say about the SS-460FL performance is that it only posted 80% efficiency at 10% load (which is still good).

If you want to have an absolutely silent PSU that can run at high loads and you don't care about cost, the SS-460FL delivers. What we can't readily quantify is the long-term stability and performance after months or years of use. The SS-460GL is a prestige object that most will find unnecessary, but it's still an awesome product. For all other costumers the SS-560KM is nearly silent through ~50% load and passive at low loads, and it represents a more reasonable selection for midrange PCs. After all, why bother with a silent PSU if you're still running fans on the CPU and GPU?
