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.
