" ... The packaging was organized and even came with bags to store unused cords. ... "
" ... Has a solid feel and the modular cables make it really convenient. ... The packaging is nice and comes with all the cables and accessories you need. ... "
" ... it came with plenty of cables--more than what I actually needed for this specific build--but being fully modular, I only had to connect the ones I needed and wasn't left with a rat's nest of unused cables cluttering the inside of the tower! ... Meanwhile, I still have those unused cables tucked away in the box . ... "
" ... If I need to add more SATA cables later I may look at some cable mods. ... "
" ... This has everything you could want from a power supply: high wattage for expandability, high efficiency for a low power bill, and modular cables for a nice tidy computer. ... "
" ... The included cables are high quality and thoughtfully chosen. ... "
" ... Fully modular easy to work with and it has all of the cabling. ... "
" ... Even though it is only semi-modular, cables are reasonable to manipulate and easy to install, even in a smaller build. ... While not all of the cables have sheathing, the CPU and main motherboard cables do which is fine enough. ... "

" ... Prefect for a clean setup and SLI or Crossfire! ... "
" ... PSU arrived quickly (2 days), was incredibly easy to install, little to no mess due to modularity, runs quietly, and powers everything with no issues. ... "
" ... It's shorter length and the fact that is fully modular make installation much simpler. ... "
" ... Installation took all of 30 minutes and cable management is GOD tier with this unit. ... Even for a beginner, this psu is easy to install. ... "
" ... Installation was easy and the cables fit easy as expected. ... "
" ... Presentation of the PSU on unboxing is very good and the quality feels solid and am very happy after installation. ... "
" ... The first thing that was really important to me and which this PSU does well is having a fully modular setup. ... "
" ... The installation was a happy one because of the design, and the performance so far (just a little over a week) has been what I expected from a top name, top of the line PSU. ... "

" ... A sturdy PSU that is easy to work with. ... "
" ... Affordable, modular, well built, comes with some nice add-ons. ... "
" ... The cords are sturdy and the fan is relatively quiet. ... "
" ... Being that these were my requirements, $200 is really not that bad a price for a top-notch PSU. ... "

" ... I9-9900k 5.1ghz 1080 ti strix OC 1900mhz no problems at all ... "
" ... The 750W point was plenty enough power for a modern CPU and high-end power-hungry graphics card. ... "
" ... Amazing efficiency at all load levels, coupled with SeaSonic's well-deserved reputation for build quality and reliability and backed up by a twelve-year product warranty. ... "
" ... Top performance, average efficiency, then fairly quiet. ... Here, I just don't think it matters much with a 65W TDP CPU and separate chambers for the already cool-ish GPU. ... "

" ... I've been very impressed with Seasonic power supplies lately. ... "
" ... Overall a very sturdy and great quality Power Supply. ... "
" ... Though in fact power supplies are arguably the most important part to any build. ... Think about it this way, they convert high AC power from your typical home to DC power that every electronic in your systems can use. ... Seasonic power supplies are one of the most reliable in the power supply business. ... Using all the standards from 80 Plus (80%) up to Titanium (90%) we can get the cost in electricity over time. ... So, the more efficient the power supply is running the less power is lost in terms of heat. ... Also, that is expecting the power supply will last that long to achieve the savings. ... Even after 3 years the trend is clear the more efficient power supplies will save money. ... Additionally, buying a cheaper power supply with lower efficient rating will most likely fail sooner and you’ll have to buy another one anyways. ... Invest a bit and buy a higher efficient power supply. ... It will be a high cost initially, but after about 2-3 years your guaranteed to be saving money overall in electricity. ... Also, you’ll be helping the environment with less electricity used! ... Hope this review helps someone understand power efficiency a little better! ... "

" ... Just note the cable length, get a better SFX to ATX adapter if you need one, and go for it. ... "
" ... Comes with all the cables you would need. ... "
