Silverstone SX500-LG 500W Gold SFX-L

Whats the hold up on these things in the US? Havnt they been at the silverstone US warehouse now for 2 weeks, yet still no retailers have them in stock?
 
Placed an order on Amazon on Jan 19, still no word yet on shipping.

Maybe the warehouse is in New England - buried under 6 ft of snow.
 
Maybe not that interesting unless you have some understanding of Swedish, but you should be able to understand the test results regardless. Sweclockers review

Yes, they seem quite satisfied with the SX500-LG, although they complain a little that the unit only stayed passive under very low loads. The fan is apparently not from Globe Fan, but manufactured by Zhen Power Year Electronics, having the model name PY-12015H12S. Very low start voltage.
 
Something I don't understand.

Globe Fan (Chieftec unit) max 32 dB, 600-1600rpm
Shen Zhen Fan (SilverStone unit) max 36 dB, 200-1500rpm
Prolimatech Ultra Sleek Vortex 12 max 17 dB, 400-1400rpm

The Prolimatech fan seems significantly more quiet, or have I misunderstood something? Can we assume that there will be trouble swapping in the Prolimatech fan anyway, since the voltage-rpm curve could be different?
 
Do you trust manufacturer measurements for fans?

No, I don't really know how they measure the fan noise. If there is no standardized way, it's all pointless and the fans have to be compared and measured by a third party reviewer under the same environment settings, in order to get the truth.

At max RPM, they are probably all in the ~32-36db range.

The important thing about the Shen Zhen one in the silverstone version, is the very low starting voltage, according to the review, from 10 to 50% load the fan runs from 207 to 690rpm.

Where as the globe fan in the chieftec model runs between 604 and 814rpm at the same 10 to 50% PSU load. Which is quite a bit higher.

Not true for the prolimatech ultra sleek vortex 12. I have tested it briefly as mentioned in the 'slim fan' thread. I'm not going to say if numbers are fudged because there is no standard for testing fans. You should think of the numbers as guides and use real user testing results (or test them yourself). Direct comparisons are the best because you can easily tell if fan A is better than fan B, plain and simple.

I decided to do another quick test with 3 fans i have around, quick specs added in brackets.

* Aerocool dead silence 120mm (1500rpm, 81cfm, 23.1db)
* Bitfenix spectre pro 120mm (1200rpm, 56cfm, 18.9db)
* Ultra sleek vortex 12 (1300rpm, 56cfm, 17db)

Let's assume bitfenix have the correct dB measurement (or use them as the baseline). The USV12 is loudest of these 3 and I would put the db at say, 20db. Slightly louder than the spectre pro but it also spins faster. However, at full speed, the USV12 moves more air than the spectre pro by about 15-20%. Another way to put it is I can reduce the power of the USV12 by about 20% to match the spectre pro.

Impressive considering this is a slim fan that should theoretically perform worse in air-to-noise. The spectre pros are good fans and very quiet, so I will test with some 'worse' fans another time. If I am correct, then the USV12 will easily beat the crappier fans.

The aerocool DS is the best one of the three and I would put it at around 15db relative to the others. It's that quiet at full speed and manages to move more air, maybe not as much as their spec sheet says though. However, aerocool DS fans are nearly double the price of spectre pros.

So who has the most correct fan testing of them all? no one. It's impossible to compare stats when the testing methodology is different, such is life. But I present to you my testing and findings. It's not lab testing but it's better than comparing spec sheets (virtually pointless).

Conclusion: Ultra sleek vortex is at least as good as a regular 25mm fan and I highly recommend it.

I have the USV14 as well that i can test against dead silence 140mm and other 140mm fans.
 
I am wondering if the Chieftec unit turns out to be the better candidate for a fan swap. Maybe that unit provides the fan with a more normal voltage, compared to the SilverStone unit.
 
Shows a ship date of the 19th now on Amazon. I'm going to hold off. My experience so far w/ v1.0 SilverStone PSUs has not been great.

Unless there is a different PCB revision between the Cheiftec and the Silverstone, they would output the same voltages for the same sensed temperature. Assuming a voltage controlled fan is used rather than a PWM fan (only 2pin).

Same here. I'll probably wait around but at the same time I really like to know what changes occur. Like with the 600 SFX 1.1 version. They didn't say anything but my biggest fears is cheaper components. I'm not sure if Silverstone does it but I heard XFX does those type of revisions on GPUs
 
You'd hope SilverStone wouldn't change to even cheaper components after all the complaining in the SX600G thread...

The SilverStone unit has a Globe Fan not a Shen Zhen.
 
A review of the unit stated the fan had a Globe Fan sticker on it, but closer examination showed it was a Shen Zhen.
 
Just got charged by Amazon and status changed to "shipping now" with expected delivery Feb. 19-21.

Fingers crossed for a good unit, because other than a later revision of this or the other Silverstone SFX models I've heard people complaining about, this seems to be the only option left for a quiet/efficient/small PSU.
 
On the way: On time
Expected delivery: Monday, February 16, 2015, by 8:00pm
Your package has left the Amazon facility and is on the way. (Updated 0 minute(s) ago)


:O

shipped via ontrac as i'm on the west coast; i guess this means the psus are also along the west coast

Strange, Newegg usually gets stock first.

Well, I ordered mine. Thanks for the heads up flod.
 
Waiting to push the big buy button...as soon as you guys send the super silent, all clear signal.

Fingers and cables crossed that this time Silverstone can release a version 1.0 SFX PS that quietly lives up to its hype.

At least my unit which ive had now for a week, is whisper quiet and semi passive mode is working as it should. I think Silverstone really nailed it this time :)

Great News!

Only have to wait a bit longer for your 6 month update and I'll be ready to commit.
 
Alright, been running this thing for the past 6 hours and my initial impressions are that the psu is pretty much silent all around with one nit pick exception. I'm only running a stock 3770k and a single gtx 970 ssc, so not a real heavy work load.

I have the psu outside the case and listening within a foot from it. It starts with the fan off and of course no noise. After running prime in the background and playing Ethan Carter & Evil Within for a few hours, it is completely inaudible among my other components. With my ear right next to it I can't hear any buzzing/whine, however this leads me to my one nit pick exception.

The fan itself (in my situation) makes two faint noises; a rhythmic tapping pattern (it kinda sounds like a horse gallop for lack of a better explanation) and a brushing noise. At load the brushing goes away completely and the tapping noise gets faster but more silent. As the fan ramps down and you can hear the psu better among the other components, these two noises are more audible from about a foot or slightly more away (I also checked to see if the fan was hitting something, but nothing I could find).

The psu from what I can tell is solid, and I understand that what I hear is completely subjective but just thought I throw that out there in case anyone else can hear the same.

I'm not sure if the sounds will bother me or not though once it's in a case and a few feet away from me, but I'll find out soon enough. I'll be watching how this thing holds up for the next few weeks.

Edit: Anyone know if this psu can go back to fanless mode after it starts spinning up? If this is possible, it's been several hours with normal operation (internal temps definitely below 41C) and the fan continues to spin.

arrived!

i managed to fit my reference gtx 970 with backplate and this psu into my ncase m1 v3. i dont think my cables are pressing down on the gpu with much force. if i lift up the 24 pin cable (not really pulling on it) i can see a 0.5mm gap between the wires and the backplate. no warping is visible as this card's backpkate is very rigid...

one thing i did for this is try to rotate the mobo as far clockwise as possible by manipulating the slight tolerances for each standoff screw. i think this gives me an additional 1mm clearance for the psu wires

now... how the hell do i manage the cables without creating spaghetti
 
Nice! It's looking like M1 v3 owners don't have much to worry about.

I should be getting mine Thursday.

nvm it is pressing slightly but not forcefully enough that anyone should be concerned.

Sure, haven't really been checking this exact thing but I've seen it in fanless mode several times after I know the fans has been on. Fan wasn't spinning last night when i turned it of to go to bed and I was playing BF4 4 hours before bedtime.

My unit spins for few seconds and goes back to fansless mode for several minutes so yes it can do it. In my case, internal idle temps are about 41c for gpu and cpu so thats why my psu does it because temps are pretty much on the border fan/fanless mode. But it doesnt really matter since I cant hear a thing when the fan is starting to ramp up, is spinning or when its still.
 
Hi all,
I just received this power supply, and so far I'm thrilled–– I've run a benchmark using Geek Bench and Unigine Valley and I can't even get the fan to spin up! Compared to the SX600-G, this thing actually does have a 0dB fan at low loads. I'll have to stress it further to see if I can get the fans to actually turn on...

Also, here's a pic in an Ncase M1 V3 with a reference GTX 970

These are good initial reports....(other than El-Dubya's ticky ticky fan unit)

Will get one up in a couple weeks for Node 304 and U2/W1-S silent builds. Will probably get a CM V550 and a SS400 and have my own silent PS shootout. Or shush-out.

Sure hope that the SX500-LG becomes the no-brainer recommendation in our new small world builds. It's one thing to tear out a PS in a big case, totally another to replace a PS in a micro-case and redo the micro-managed, snake-pit-wrangling cable-routing gymnastics.

Thanks for the reports, you intrepid early adopters!
 
blah i overtightened and destroyed the threads of one of the mounting screw holes
 
I got mine today and I'm noticing the clacking as well. I think if the fan stayed on at a higher rpm then it would be quieter. Mine turns on and off repeatedly and you can definitely notice it because of that.
 
I just finished my NCASE M1 build (most of it) with the sx500 lg. I can also confirm the very light "galloping" sound. I hear that sound until about 1.5 feet away where it's not as noticeable. I also have another sx500 lg PSU to install to another M1 case, but it might be a little while. It's still overall quiet, and my Noctua 120mm CPU fan is louder most of the time.

edit: Stress testing the CPU atm and the PSU galloping sound sounds a little different, less like a pronounced galloping and more like a HDD arm moving but quieter. Most likely because the fan is running faster. Still just about as audible at 1.5 feet. I'll report back in a couple of hours once the test is over.

edit2: The sound is still there after the stress test but not as constant, it has become seemingly random. It's a bit of a shame. It would be very quiet if this fan sound wasn't present. Mine doesn't have any coil whine whatsoever.

edit3: It may not actually be a fan problem. When I blew air with a can, the fan was pretty quiet. Mind you I'm probably not hitting those high RPMs. Maybe it's rather the motor creating that sound.
