Features

  • SFX-L form factor power supply, not compatible with ATX form factor unless adapter is purchased separately (sold as "PP08")
  • 1000W continuous power output rated for 24/7 operation at 50C operating temperature
  • High quality construction with all Japanese capacitors and single +12V rail with 83.3A

  • Please use only cables included with the power supply for best performance / reliability

Description

Since its launch in 2015, the SFX-L form factor has garnered popular recognition and support among enthusiasts with its larger 120mm fan able to achieve better balance of power and quietness in small form factor PCs than what was possible with standard SFX. And as a leader in power supply miniaturization, SilverStone has continued its efforts in advancing the SFX-L forward to reach ever higher limit. The SX1000-LPT not only has unprecedented 1000 watts of power output but also has the second highest level of 80 PLUS efficiency with a Platinum rating. It includes all features available from top of the line SilverStone PSUs such as flexible flat cables, all Japanese capacitors and advanced semi-fanless capability. For those looking to build the most efficient small form factor systems possible with great quality and power, the SX1000-LPT is definitely the top choice.

    • No issues so far
Size: 1000W SFX12V
Powerful PSU, runs my new PC fine with an i7 13700K and an Intel a770 Bifrost. Haven't heard any noises from it so far while playing games or media creation. Just be careful of the size, it's longer than other small PSUs so you may have trouble fitting a GPU with it depending on the case (ITX). I'm using it in an NR200. ... show more

    • Solid PSU!
Size: 1000W SFX12V
So far this power supply has been super solid. No issues after a couple of power outages, and seems to put out consistent power. Easily powers high end hardware with no unexpected shut downs. Only negative I have with this thing is the whining. You can here it depending on the power draw, a high pitch whine coming from it. It doesn't bother me, because I usually have headphones on most of the time, but just something to be aware of. Overall, happy with my purchase. I have always trusted Silverstone power supplies and actually have one 10 years old that's still going strong. ... show more

    • Noise is great so far I don’t hear it!
Size: 1000W SFX12V
My update of SilverStone 1000w. Absolute beast! Can’t ask anything more than running my Red Devil 6900XT Ultimate! This is the pinnacle of the SFX-L PSU! So far my replacement is running smooth! Have this in my Lian Li O11 mini. Cables are a bit too much for this type of case but I’m very satisfied with this product! If anyone is planning on running their 3090 or 6900XT in a case that requires SFX-L this is the one I would recommend 10/10 ... show more

    • A review reply to Shaun Renew
Size: 1000W SFX12V
I personally own this PSU. Picked it up off Amazon as well but it was just one of those things I didn't feel inclined to write a review about at the time. In any case, it's a good PSU given the form factor, no disputing that. Price for this is what gives it a 4-star rating because there are very few case uses for this type of power supply, that can output that much power, that actually require it. If you're an SFF builder, then usually a 750/850W is all you need on the high-end, even with a custom loop, and I say that with building in cases like a Meshlicious, A4H20, Q58, Ghost S1 MK III, NR200P and even an O11D Mini X (what this PSU purchase was originally intended for but ended up not needing it since an 850W was plenty for a 12900K and 3090 FE in a custom loop). All using hardware in the ranges of a 5600X, 5800X3D, 5900X, 12600K, 12700K, 12900K, 13700K and 7900X paired with the likes of a 3080Ti FE, 3080Ti XC3/FTW, and 3090 FE. Now that that's out of the way. For Shaun Renews remark in regards to cable swap outs, given this PSU is modular like many good mid-range to high end PSU's, simply put you cannot just swap modular cables from one PSU to another...typically and technically speaking. There are pinout types/differences across different brands/series of PSU's. In some cases, on the technical side, yes some series PSU's from "Brand A" may be the same type/pinout as "Brand B". This is not always the case though, so for anyone expecting that, take that into consideration. This is also why PSU extensions are still relevant even though you can outright buy sleeved cable packs to completely replace ones that come with a PSU, because pin arrays are just different sometimes for different PSU's. Just thought I'd throw that out there! Thanks ... show more

    • Small but A lot of power
Size: 1000W SFX12V
This product is amazing if you doing a mini pc build and you’re running a 30 series card. It’s very quiet compared to my other PSU. I would recommend it

I was just starting to plug everything in when I noticed one of the PCIe cables with loose wires out of the box. As I need all three included cables for my GPU I will be returning the whole unit. Never seen such horrible cables included with a PSU before, honestly says a lot about Silverstone's QC. As this is my first Silverstone PSU (or product) I'm just going to look elsewhere. ... show more

    • Small but very powerful
Size: 1000W SFX12V
Wow, this thing is small but packs a punch. Hard to believe there's a 1000w crammed inside this little box. Very power efficient and can't even hear the fan. Fully modular too. We'll see how long it lasts.

    • Awesome power in a small package
Size: 1000W SFX12V
1000W in a SFF case?!?! No problem with this psu. Easy to install and works great. Kind of expensive, but there's nothing else out there. Probably overkill for almost any rig that needs a SFX psu, but you can't go wrong with this one.
