  • A wonderful PSU, and Cheaper than comparable 1000w SFX-L PSU's on the Market!
Style: SFX-L Size: 1000 Watts
The Many Good things: -Price point is great - there is no other SFX-L 1000-watt psu on the market for under $300 (at least at the time of writing). - PSU is powerful and is easily able to handle an overclocked PSU and overclocked GPU - even the most recent, newest GPU's are compatible like the 7900 xtx and 40-series cards (at least, at the time of writing)! - Its seriously super quiet. The Fan doesn't even need to turn itself on most of the time. That might be a problem for some but come on.... youve got an ITX build. You know its gonna run hotter than most build anyways. - Its got a TON of PCI-e connectors, all fully modular! That means that you've got many options for linking it up to that power-hungry graphics card you've been dreaming about. You can use one dedicated cable per power connector on your GPU. Im using an AMD 7900 xtx with three power connectors - each using their own dedicated cable! -Wires are NOT braided, but I think that this is actually a GOOD thing! Hear me out - Braiding equals unnecessary bulk and additional inflexibility, making wires harder to hide within the smallest of ITX build. The wires as well as connectors going into the PSU are super small, more flexible than competitor's PSU's and easy to route! The only BAD thing I encountered: I originally purchased this PSU with the intention on pairing it with the Phanteks Shift XT ITX Form Factor PC Chassis... but for some reason this was a bad combination. The Shift XT Chassis wasn't able to properly ground itself with this PSU. And as a result, any random contact with the Shift XT Chassis metal plating would result in a static shock and ZAAAP! The computer would turn itself off. This was fixed by changing the PC case from Phanteks Shift XT to a Lian Li A4-H20 - and I never experienced the issue ever again. ... show more

  • Corsairs SF line of power supplies always deliver.
Style: SFX-L Size: 1000 Watts
After using many SF power supplies from Corsair for years, my expectations are very high. I expect silent performance, no coil whine, and delivery of the advertised power. And to no surprise, the SF1000L delivers. I am not sure what secret sauce Corsair uses to get these power supplies to be so efficient and quiet, but other brands I’ve tried over the years have never been able to match its performance while maintaining absolute silence. The smaller type 5 connectors are a nice, although a completely unnecessary change. If I had any real complaint, it’s the length of the cables. More specifically the length of the 12VHPWR cable. It seems extremely short, even for many ITX builds that use a gigantic 40 series card. If your going to use fancy new small type 5 connectors and only include an extremely short 12VHPWR cable in the box, you should at least offer a longer version of the 12VHPWR for sale on your site or even an extension for it. Instead to extend the length of the cable for my build, I ended up purchasing a dodgy no-name brand 12VHPWR cable extension, which has worked fine so far.. But given the history of the 12VHPWR since its launch, I’d much rather have purchased a genuine corsair cable. Cable length aside, the power supply is wonderful. I don’t see myself buying any other brand of power supply as long as corsair continues to make high quality power supplies like the SF1000L. ... show more
