    Good PSU if you need more power

    I purchased this PSU to replace my old one when the cooling fan died. I wanted something more powerful that I could reuse in a future build. This unit was easy to install and the modular cables helped prevent unnecessary clutter in my case. The logo on the side looks cool so if you have a case with a window it will fit right in (logo is on both sides and reversed so it will look good on almost any case config). My only beef with it is that the 24-pin mobo cable is a bit long. I ended up stuffing it behind my case's back panel.

    Looks and Works as Advertised

    The supply is larger then my standard tower can fit. Therefore I upgraded to Mid Sized Tower for $70 (Recommended). Just not enough room for cable organization and can cause less air flow to your Graphics card. The cables aren't colored so it can be confusing since there's no instructions for amateur installers...but its only a power supply so it will be simple once you organize. And the main power cord has a black braided cover so it looks really neat. Corsair usually has good quality and so this is hasn't proven wrong.

    Coil Whine is INSANE

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    I purchased this because it is semi modular, 750W, and decently priced. After finishing my build, I noticed bad coil whine during gaming, especially during loading screens. I thought it was my EVGA 980ti ACX 2.0 but after closer inspection it was the PSU! Honestly, after this build I used an EVGA 1000W G2 in a new server build and the quality is AMAZING. Not knocking Corsair, but this one definitely turned me away.

    This replaced my 4 year old 500 wats power supply. This power supply is COMPLETELY silent, PC turns on very fast now too. Dual tasking, and I still dont hear it.

    Great Product!

    Nothing wrong with the product itself, but be wary about picking up this item from the Northridge store on Nordhoff St. They somehow received a batch of units packaged for the EU. The power cord inside the box will NOT fit our outlets here in the states. Before leaving the store, look at the complete model number on the UPC label to make sure it says "-NA", as opposed to "-EU". I BELIEVE the actual psu is the same, regardless of which type of power cord is in the box, but all the same, I'd rather get the -NA version than wonder, if.... ;)

    Great power supply

    I bought this as a replacement for a failed power supply. It was extremely easy to install and connect. The modular power connections made it very easy to run the cables easily within the system. I especially liked how the SATA connections allowed me to connect all four of my SSD off of a single cable.

    A solid power supply that handles the even the heaviest loads well. Works for any RTX 30 series card, as long as you make sure to follow the specs on the GPU for compatibility.

    I had to buy this power supply because my old one died. I did a lot of research on which one to buy and this one was one of the best for the price. It is working very well and actually is a lot quieter that my old one.

    A bit pricey but works.

    Replaced a broken PSU with this one. Was in a rush so I couldn't get a better deal than eighty dollars. I love that it's modular giving more room for air flow and it worked great. Runs quiet, no complaints after 1 week.

    Sufficient Power with reasonable price

    For this price range, this power supply provided sufficient power to your system. Detachable power cable from the power supply to your PC components help reducing the hassle for organizing your cable inside of your case.

    What a cool beast!

    I bought and installed this about 2 weeks ago. It installed just as promised (IMHO, if you're into building PCs, you WANT a modular psu). It works perfectly. If I could ask one favor, it would be great if this came with an LED light-- and killer if you could program it like the Razer Chroma peripherals

    Excellent power supply for a mid tower build.

    Excellent power supply for a mid tower build. Runs very quietly and stays very cool. The cables are just long enough to snake through false wall without too being either too short or having a large amount of excess. Would recommend it.

    replaced a beat up power supply with this easy to use product. I like that you can chose how many connections you need to attach as it makes the internals of the case cleaner.

    a great power supply for the price!! lots of connections. I bought this power supply on dec 10 2014. it fit perfectly in my case. comes with detachable connecters for when you dont need to use them. The power supply went out 28 days after i bought it. Bestbuy return policy is 15 days. i have to send it back to corsair. I will never buy another item from bestbuy ever. at least frys has a 30 day return policy on most of their items.
