    My power supply died and I needed a quick replacement. Found this one at my local store and couldn't be happier. Easy to swap out and nicely labeled connectors.

    Corsair Power Supply went in easily. Plenty of connections with nice wiring. The fan is ultra quiet too which I like.

    In the middle of a project, the power supply in my computer failed. Tried to find one of the required power rating locally only Best Buy carried it. Not only did they carry the power supply but it was available locally. Within an hour, I had the power supply in hand and installed in another half-hour. Power supply works great. It has all the connectors needed to connect to the motherboard and drives. Project saved and completed.

    This pcu is great! Whisper quiet. I can barely even tell it's on... It has a nice intake fan, keeping it cool for graphics intensive gaming. Might not recommend it for someone who doesn't really NEED 750 watts: most components usually won't require half that power output. But if you're like me, trying to upgrade a pc into a "gaming" pc, then yes--I'd recommend this pcu. I plan on adding more components later on and SURE, I'll be requiring more power. So yes. A great PCU. Price wasn't to bad either :)

    The power supply works fine if you keep the load reasonable, but gets very hot and loud if you load it up significantly. Worked fine with an RTX 2060, but I swapped in an RTX 3080 (using 2 x individual cables, not the pigtails), and while it worked ok, the PSU became the LOUDEST component in my system, even louder than the stock 3700X Wraith cooler. Great PSU if you don’t mind the noise! Personally, I couldn’t stand the noise, so I returned it in favor of the RM850x, which was a BIG upgrade!
