Nach dem erfolgreichen Ausbau und die f?hrenden SFF (Small Form Factor) und SFX-Netzteil F?llen in der DIY (do it yourself)-Markt, haben Silverstone Ingenieure ihre Push f?r den Aufstieg in diesen Kategorien durch die Freigabe einer wahren Update-w?rdig kleinen Formfaktor Stromversorgung fort, die ST45SF-G. Obwohl er die H?lfte der Gr??e einer regul?ren ATX-Stromversorgung kann das ST45SF-G noch produzieren Dauerleistung von 450W. Sein 80 PLUS Gold-Effizienz ist ein gro?er Sprung von der vorherigen SFX besten 80 PLUS Bronze-und der Voll modulare Kabel ist auch das erste seiner Art f?r diesen Formfaktor. Damit die Benutzer auf einfache Weise nutzen diese hervorragende SFX-Netzteil, ist ein Adapter enthalten, um zu konvertieren ST45SF-G, in jedem ATX-Geh?use zus?tzlich zu denen, die nur SFX passen zu montieren. F?r SFF-Benutzer und f?r Silverstone ist der ST45SF-G mehr als nur ein Upgrade, es ist ein wichtiger Meilenstein f?r DIY Desktop-Computer.

I have this PSU in a Lian Li PC-TU100B, which previously housed the Silverstone ST45SF-G. My issue with that PSU is exactly what Silverstone describes in the "Product Description" of SX500-LG - the high-pitched noise. It was not loud, but was very noticeable and thus extremely annoying. The SX500-LG addresses that exact problem with a larger fan and a less aggressive fan curve.
Before purchase you need to make sure that it fits in your case because the SX500-LG is longer than a standard SFX PSU.
Other features that I like:
- Flexible cables, similar to the PP05-E set
- Native support for dual 6+2 pin PCIe power connectors
- The ATX bracket included has a better build quality
On the plus side, I purchased mine from Amazon. You can't ask for a better company top deal with when it comes to issues like this. The return was processed and a new one shipped out. No muss, no fuss. If the replacement unit is silent I'll be happy... if not I'll report back here to let everyone know.
UPDATE - DEC 11, 2015
Found a forum where Silverstone was discussing the noise issue. As a result of the statements made I may discover a replacement PSU isn't going to fix the problem for my specific installation. I'll report back once I get the replacement fan installed. Hopefully I'll get lucky.
Here's what the Silverstone rep had to say:
"The SX500-LG's uses temperature based fan control... We believe the ticking noise that some owners of SX500-LG heard is the result of the ramp up in voltage applied to the fan by the temp control. This is more noticeable around the voltage required to start the fan."
UPDATE - DEC 13, 2015
Received the replacement 500W SFX-L from Amazon. This one is dead quiet... no noise of any kind! Sweet!
UPDATE - DEC 16, 2015
Bad news... Three days of perfect function... then it failed. Just up and died in the middle of making some updates. Swapped the replacement with a known good supply and everything was fine, put the bad one back in and nothing... Dead. Believe it or not this failure isn't much of a concern as I'm aware any electronic item can fail... TV's, Receivers, Blu-Ray players etc. Plus, I was unable to find anyone else who reported the same type of problem. I contact Amazon for another replacement.
UPDATE - DEC 20, 2015
Received the replacement from Amazon. Thank God I ordered from Amazon and not some other online outfit. From years of buying computer parts online I know any other company would not have been as customer oriented as Amazon. From experience, other computer parts company's would have been blaming me... or making me file a warranty claim with the manufacturer.
The good news... I'm up and running again. The not so good news... this one is not silent as the one that failed but it is a lot quieter than the first one. Where the first PSU made loud clicking sounds... this one is more of a quiet squeak. Sounds like a baby mouse in the unit... or a noise like dry fan bearings... squeak, squeak, squeak. However, the squeaking sound occurs when the fan is not spinning. Once the fan kicks in and starts spinning the squeaking stops. That said, I'm going to cut my loses and just keep this one. Amazon has been more than fair and has gone above and beyond in helping me with this PSU. Besides it's not the end of the world, I can't hear it once I get a couple feet away. As mentioned in my Dec 11th update, the noise issue is a known complaint among some customers but per the manufacturer the PSU is working as designed and depending on the application, you may or may not experience some noise.
NOTE: If you must have a Silverstone SFX-L form factor PSU... and can wait a week or two, Silverstone is getting ready to release a 750W SFX-L, and it's Platinum rated! Plus, the fan control circuit has been redesigned which should address the noise issue that seems to plague this unit.
+800w platnium rated, plenty of power for your needs
+sfx-l, should fit in a variety of mini itx builds (or help in tighter towers)
-claims to stay within +/- 3% voltage, however, i experienced almost 4% vdrop under load (11.540v on 12v rail)
-this psu gets VERY hot under load
-no sfx to atx adapter included
my current build had a very limited space for a power supply, so i turned to silverstone to see if i could get away with a sfx-l psu instead of trying to cram a full size psu in the case. i currently have a r7 2700x and vega 64, so i figured 800w would be good to keep it within peek efficency while gaming and having extra power for overclocking.
i install the psu, fire up a few benchmarks (nothing crazy nor am i overclocking) and was shocked to see such drop on the 12v rail. even swapping in a 1080 didnt do much to reduce the vdrop.
since then i yielded, got a evga 1000w g3, managed to barely squeeze it in, and now my voltages stay at 12.093v both at idle and under load.
i dont believe that 200w makes a difference in this scenario nor do i believe 800w isnt enough for a 2700x and vega 64 (yes i know vega is power hungry). i will say though i did get a v1.0, so i may have gotten unlucky and got a bad one.
i dont believe this is a bad power supply, and will hang onto it maybe for a future build (unless silverstone will swap it or something), but i will say to keep in mind, for the smaller size you are making compromises
80 Plus Gold
Relatively quiet fan (even without the zero RPM fan mode of the v1 version)
Flat black cables
Slightly larger SFX form factor (130mm doesn't leave much room in my FTZ01 for dealing with the cables)
The V2 of this power supply doesn't really have much different than it's original counterpart. The main change with the V2 version is the removal of the Semi-Passive fan mode of the v1. There were several complaints about the fan making a "grinding noise" and some buzzing as well but this issue seems to have been severely reduced with the V2 PSU.
Overall this is a very nice small power supply. It is a bit larger than the standard SFX form factor so that is definitely something to keep in mind, however as a result they were able to slap on a larger 120mm fan which definitely helps keep this thing cool and quiet. This is a solid little power supply with 80plus gold efficiency that gets the job done.
