Customer Ratings & Reviews

Purchased this to replace an old BFG power supply. A little overkill in wattage for my system, but I like to keep my power ceiling higher than necessary, in the event I ever add a second gpu. Love the modular design, as I only used about 4 of the ports and the cables were easy to route in my Thermaltake Core V31. My system: i7 2600 Be Quiet Dark Rock Pro 3 8 gb 2x4 Corsair 1333 mhz RAM Sapphire R9 290

I used this power supply to replace the supply in my gaming PC. It has no problems powering my sandybridge CPU and GTX 770 graphics card. I'm always hesitant to replace parts from local shops (Best Buy is one of the only stores that has PC parts in my area) due to little selection but I needed a supply that day and Corsair has treated me well in the past. After I got the supply, I did a search for others online and it turned out, this one was a great deal for the money (It was on sale when I bought it).

I bought a mid-level gaming system powered with the minimum it needed for all components. Within a week I burned out the original 426W power supply. I learned that the more power you draw the hotter and louder it is going to run, with peak efficiency around 50% of the power supplies maximum wattage. This one runs nice and quiet since my power draw is around 60%. The modular design also freed up space in the box for airflow so the system runs cooler overall as a bonus. I've had it for a couple months and I like it.

This is my second Corsair power supply. The first one only lasted 5 months so I purchased another one to replace it so that I would not be without my computer for10-14 days while the old one was being warrantied out. I usually buy EVGA or Thermaltake, but this was all that was in stock at the time and I didn't want a no name brand. I give it 4 stars because it failed so quickly, but it was easy to install and customer service was great. The only other complaint I have was having to pay $20 to ship it back to be replaced, but they all do that now. Seems like if it were still in warranty, they all would pay shipping both ways.

My latest gaming system and I was tired of clutters of wires spoiling my shiney new hardware. After selecting an appropriate power needed for my system - plus a generous allowance for expandability - i went with this 750W unit. Plenty cables came with it and given the bargain price they were of adequate length, a full size tower might need longer ones; my mid tower was no problem,even after some ambitious re-routing. Runs nice and quiet even under demand from my R9 card on max.

I needed a new power suppIy for my new system build and I consider Corsair to be a trusted brand. Best Buy had this on sale for a good price. This is my first modular p/s so I can't really compare it to others. However, I can say that installation was a breeze and the interior of my tower is a lot less cluttered without all the uneeded cables being crammed in there. Less clutter equals better airflow. It is also very quiet, can't even telling its running.

Cant beat the price for this PSU. Performance is similar to most Bronze rated PSU's. I went with the CX series due to the constant cooling. The next step up utilizes a fan that only draws power when the PSU reaches a certain temp, which can negatively affect case temps, and is obnoxiously loud when kicking on/off. Powers my i5 4690k, 2 hdd's, GTX 970 4gb FTW SC, 16gb RAM, 1 240mm and 3 LED 120mm, fans + 2 cpu cooler fans without a hitch. Would buy again.

My power supply crashed and I needed a quick fix. Well, this fit the bill! Good price and it was easy to install. Plus, it is a lot quieter than my old one!

If you are building a pc and don't want your computer case cluttered up by a lot of extra cables, this is the way to do it. The power supply comes with specific cables for SATA and ide, as well as motherboard ATX power cables. You only need to install the cables you need. I have a mid-tower case with a window and so the installation was looking neat and efficient when I finished. A really easy job.

I was doing a custom computer build I wanted to use some of my older parts. After putting the motherboard and processor and RAM together I realized the power supply didn't work. I went to Best Buy to get a new power supply. And saw what they had on the shelves. After looking up reviews, I decided on this corsair 750. I like the two cables are modular so I don't have to have additional wires in my case. However I wish the cables were wrapped differently instead of the flat cables they have that aren't as flexible as I would like.

Great over all modular power supply. Plenty of cables to sli and have multiple storage drives if that is your thing. Neat and clean look. Small and compact for the wattage. Fits in pretty much every ATX mid sized case. Had plenty of power output for high end components. No need to go higher than 750 watt on normal computers ( most home pcs have 400 to 500 watts power supplies ) .. Great product.

I build PCs as a hobby for use as HTPCs, gaming rigs, and most recently as crytocurrency mining rigs. This PSU was purchased for a mining rig. Corsair is a top quality brand, and their warranties are fantastic (I've personally had to RMA a PSU that failed after 1.5 years in an HTPC, and they replaced it with a more current PSU that had a higher max wattage and higher efficiency rating with minimal hassle). When running a $1000 rig 24/7 at 100% draw for the GPUs, you don't want to cheap-out on your power supplies (though I sort of did by going for Bronze rather than Silver or higher). Plus, modular PSUs just make cable management (even in open-air rigs) much easier. This PSU is semi-modular in that it has hard-wired connections for the mobo and cpu power, and modular connections for everything else. This is fine because with very few exceptions, you'll always be using the cpu/mobo connections in any PC setting. Only some of the cables are sleeved. The PCI-e, mobo, and CPU cables are sleeved, but the SATA and molex cables are not. While this isn't a deal-breaker, it is bit of a let-down because it affects the aesthetics in a traditional rig, and the way the non-sleeved cables are laid out (almost like old ribbon cables) they can be difficult to bend and manipulate. At $99 for a 750w semi-modular, 80 Plus Bronze PSU, this is the absolute upper end of what I'd be willing to pay (I had a gift card, so it was easier to justify, and it was available in-store when I needed it). It has worked without any issues providing power to 3x R9 270s, a 65w cpu w/ stock cooler, 4x 1gb sticks of DDR2 ram, and nothing else. I would not recommend running 3x GPUs of this PSU for a traditional PC with additional fans/peripherals unless you are using one of the newer Maxwell-chip cards. But again, I've had no hiccups with it so far, and I trust Corsair's warranty fulfillment unconditionally.

Power efficient, almost silent, detachable cables and very reliable!

Replacement for factory power supply in high-end Dell desktop. Easy to install and more than enough connections. Only connect the cables you need, so it saves space. Completely resolved the reboot and hangup problems I was seeing with the old PS. The PC runs better than new now!

I used this power supply to replace one that went out in my Daughter's PC. She gets all of my hand me downs so the PC is still VERY high quality and performing. The P/S is quiet and works like a champ. Corsair makes quality products and their P/S lines are no different.

powering Sabretooth Z77 with i7-3790K, 32GB, 5 ea 1TB HDDs and GT 780 video. Quiet, Runs 48 or 72 hours between shutdowns, never a problem. Cables are plenty long for a full sized tower. 3 chassis fans and liquid cooler for CPU. Love the modular feature to only plug in those power cables that are needed, no extra cables to tie back.

I bought this in a pinch when my original power supply when it wouldn't support my upgraded video card. It worked so well that I decided to keep it in the computer. I like the modular design of the cables. Most come that way now, but I've seen a few without (m old one). It was easy to install.

I upgraded to this power supply after a name brand 600w power supply from Best Buy died on me after 3 months. Not running anything crazy- an amd 8 core, and one graphics card. This is my first fully modular power supply, so I appreciated being able to remove unused cords from my case. I am most impressed with the noise, or should I say, lack of noise, this power supply puts out. It runs very smooth and quiet and I haven't had any issues with it so far. I'm happy with the wattage in case I want to upgrade to two graphics cards in the future. I had a smooth time with in store best buy staff when swapping my in warranty 600w for this one, and I just needed to show my best buy rewards history (since I made the mistake of tossing the receipt). Warranty is 3 years, which seems fair enough considering how often I build a new computer. Highly recommend this baby.

Easy to install. Lots of power! Quiet too. Removable cables so if you don't need some connections you can reduce clutter

Needed a power supply that supported a graphics card and this one did the trick. First time installing one but if you look up info on the internet its pretty simple. No issues and actually seems like my computer is quieter after installing it
