What is it that stops you from buying a proven and tested Corsair HX650W? It's known to be quieter than those S12s. Seasonic-made too! :lol:


Neither the S12D silver nor the HX650 bronze have been reviewed by SPCR so I can't say I have the confidence you display towards "proven and tested" when it comes to noise levels.

I pulled the trigger on a X-650 Gold the other night and it should be here middle of next week.

Then you simply chose the best. :wink:
The "proven and tested" refers to the fact that the HX650W has the same fan setup you can find in the previous HX series, and that's known to be good. And the improved efficiency and maximum output in the newer one means good news. :wink:

I just picked up a X650..
Just thought I'd share a few thoughts I haven't seen anyone mention.

Wire Thickness
All the wires from the modular cables are 18 awg! :shock:
It's usually much thinner on the power supplies I've owned thus far - usually more than 20 awg. (i.e. It's mostly 20 awg on my S12 Energy Plus) This makes the cables in the X650 much more robust but also slightly stiffer. Pessimists might question the necessity of 18awg, but if it's the same price, I'd want thicker wires :P

Power Cord
The power cord that comes with the PSU is 16 awg.
That is pretty rare as manufacturers usually skimp on this with a 18 awg cord. Actualy, I've never seen anyone include anything but a 18 awg power cord for PSUs, so good for Seasonic..

Sleeving
Sleeving isn't made all equal and the X650 has much nicer sleeving than the S12 Energy Plus. It's "denser" and hides more of the cable underneath and just plain looks better. Also, the heat shrink has been glued in place ensuring everything stays where it should (i.e. versus just zip-tied or let loose leading to slipping/sleeving moving around in some units I've seen)


Overall I'm very pleased with the X650. It's a shame I forgot to measure AC draw before and after the upgrade :(

The important thing you forgot to mention is how does it sound?

I got the X-750 yesterday and plugged it in with only GPU fan running. Harddrives and optical was disconnected except the SSD. It was dead silent in idle from 20 cm distance. If I put my ear onto the PSU, I could hear a faint sssh sound like a gas leak. No coil noise and such that I was afraid of.

I connected everything and booted the machine into windows. The fan doesn't run in any idle operation, so I opened MSI Kombustor (MSI's furmark) and it took 4 minutes into Kombustor with 1920X1200, 8X AA, stability mode and extreme burn before the fan started. At first, it made a very low noised TTJUGH sound, like it haven't decided if to start or not, then, when the fan stabilized, noise went away and it was inaudiable from 20cm in my setup. The noise didn't rise above my ambient sound and I was listening directly to it (I have a Thermaltake Mozart TX cabinet, where the fan is in its own compartment. I was running Kombustor for only 10 minutes and when I hit ESC, the fan went off immediately.

The X-750 I received had a plastic fan air deflector positioned near the outtake of the PSU. I recon its made to push air back into the PSU before it goes out. I listed and couldn't see that there were any distortions in the sound or turbulence noise coming from it when the fan was running.

All in all, I am very pleased with this PSU! :)

My system is:
Asus P5Q
Intel Q9550@stock
Powercolor 5870 PCS+ (with custom fan profile)
4GB memory
1 SSD harddrive for OS
1 1TB harddrive for games
1 DVD burner
2 case fans (Noctua NF-S12-1200 on fan controller at lowest speed)
1 Noctua CPU cooler with Noctua fan controlled by silent settings in bios
Thermaltake Mozart TX case modified after all the rules I could find on SPCR

Thank you! :) Much appreciated.

I did have an account earlier, but almost all posting was in 2008 in the newbrief section. The account was deleted and MikeC recommended me to re-registering it again.

I've been an active silencer for many years now and Silentpcreview is an invaluable resource for someone who take the words "blessed silence" seriously. I usually don't buy new hardware without checking here first about how noisy it is and the few cases I did, I check here how to correct the mistake. :P

Sea Sonic Unveils the New X-Series 80PLUS(R) Gold Power Supplies
Computex Taipei 2010

Last year, the launch of the Seasonic X series, the world’s first 80PLUS(R) Gold certified multi-output ATX power supply, was a total success. The full modular X-650 and X-750 won many accolades and industry awards for design and performance excellence and became the industry standard for 80PLUS(R) GOLD.

Once again, Sea Sonic takes center stage and leads the way in high efficiency and performance innovation with the Computex launch of a whole new family of X series.

 X-Series; Fanless 400 & 460 watts; for absolute silent performance
 X-Series; 560, 660 & 760 watts; for perfect balance of power, performance and efficiency
 X-Series; 850, 1000 & 1200 watts; for heavy duty work load and top end performance

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.


http://www.seasonic.com/new/twevent20100525.htm

The fanless psu seems pretty interesting if it doesn't have any problems with reliability.

What's the difference between these and the previous 650 and 750 W models (well... besides the additional 10 W :D )?

The new Corsair AX series PSUs are (apparently) based on tweaked X-series Seasonic PSUs, maybe these new 660 and 760W models are said tweaked versions?

O too think they simply chose to declare a slightly higher wattage only to differentiate their "new" units from the "old" ones. And I thought this was only a Thermaltake/Coolermaster's business... :roll:

Mike, wouldn't happen to have one of the new passive X Series PSUs in the lab yet, would you? :)

It's not a big deal, I'm sure they qualify as 660W and 760W max models by legitimate testing.

Actually yes, but it's not a production sample.

So there won't be any difference between the 750 and new 760 model except the 10W? Do you know when the 760W will be released?

Nope, there's no difference at all except for the label.

One thing i heavily dislike on Seasonic X series (yes, i own a X-750) is that Seasonic doesn't sell replacement cables at all, which somehow defies especially the reason for modular 24-pin. For example i want a shorter 24-pin cable (15-20cm), but i want to keep the original 24-pin for later reuse. Can i do that ? No :(.

Still looking like the ultimate PSU for someone who wants the best (I don't care about its quietness), but doesn't want crazy high wattage.
I can't wait to get mine! :lol:

Welcome to SPCR!

http://www.newegg.com/Product/Product.a ... 6817151097 does look interesting. I wonder how it compares to the X-650 in effeciency in the 65W to 200W range.

Of course newegg is selling the 400W and 650W versions at the exact same price.

OK http://www.seasonicusa.com/NEW_X-series_560.htm finally

and http://www.seasonicusa.com/NEW_X-series_Fanless.htm (for the 400 and 460 watt versions) Odd that the URL says fanless but the description describes them as being just like the rest of the X series with a fan that comes on as needed.

According to Mike & colleagues, it won't be any better in that regard.
See the 5 posts from this point....
