Product 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.

Great PSU, could be better for the price

Great PSU, could be better for the price
I had to buy this PSU for my build because the Lian Li 011D Mini has to use a SFX PSU and since I was running a pretty power hungry GPU and CPU, I really only had one option.To get the bad out of the way, my only gripe with this PSU is it seems like you can't use another companies cables with this PSU. I tried to use some EVGA VGA cables and they would not connect to the PSU. Weird for a supposed modular PSU...If this is wrong, I would love for someone to correct me.But that is honestly the only "bad".It provides all the power my PC can ask for and it's pretty much silent even under load. Can't ask for much more.

1.0 out of 5 stars Didn't get very far in my build.
Reviewed in the United States on January 15, 2023
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.
