DOA

Pros: Physically looks like a great unit. But...

Cons: Looks can be very deceiving...

Won't power on and now I get the choice of waiting for the RMA or spend more and buy a more reliable brand (with a hope it works Corsair °¿°) backup in storage for the future.

What happened to quality control Corsair?!?!??

Other Thoughts: This 'was' being used in a fresh build. Corsair had good reviews from my research, maybe I wasn't indept enough but this was the first and will be the last Corsair I'll ever purchase.

Good so far

Pros: - Fully Modular - ample cables of good length - connectors, wires and braided sleeves are all black and of quality construction – They blend right into my case. There is a bag of little black zip ties. I use them. I have plenty anyway, but
- Nearly silent – When the fan is running – My case fans are louder anyway
- Corsair is a trustworthy brand with a good (10-year) warranty and return/repair handling
- The Gold rating is nice, but not really a big factor for me
- The price is right for a fully modular PS, especially if it has the quality to last 10 years or longer
- It looks good, smells good (like all new electronics) and is packaged intelligently

Cons: - The included manual has sections in 10 languages and is for 5 different tiers of this product. How about save a tree and provide a postcard with a URL and a QR code?

Other Thoughts: Out of all the failures I have had, the PS is the most frequent, followed by hard drives, Logitech wireless mice and un-maintained water cooling systems. You never know when they are going to fail. I personally have never had a PS fail on day 1, but I have seen anywhere from 1 month to 2 years. The ones I have seen go, go up in flames!... well at least sparks and burny smells. I always worry it might burn the house down if I am not there, and usually I am not. Some have just degraded to the point of causing strange behavior – which is really hard to troubleshoot. The few I have diagnosed turned out to be due to capacitors, usually bulging, but sometimes exploded. If this model’s “Japanese capacitors” are truly better, then I will be happy. If any PS makes it beyond two years in your exact same rig, you are probably good to go for a very long time.

Since I don’t like down time, my approach to sizing the PS is to ensure my most likely point of failure can handle the peak load without breaking a sweat. That means not driving the whole or any components anywhere close to their limits. That is why I add +50% to +100% capacity to my calculated power draw to size the PS. Yes, that is right – double the capacity! Everything runs cool, quiet, more efficiently and in the mid-range of each components electrical and temperature specifications. This might cost you an extra $30 - $100 (maybe more on the super high end), but you will make some of that up in efficiency, come out way ahead when you don’t have to suffer down time and heaven forbid the rare case of burning the house down.

750W should be plenty for your average gaming rig with one decent video card. There are two PCIe cables, each with two connectors. Probably more cable than needed. Based on what I just laid out, driving multiple high-end video cards will likely lead to early failure of any 750W supply. Who knows, maybe this one is different.

I gave it 4 eggs only because it has only been installed for 3 weeks. I will upgrade to 5 if it makes it to a year.

Update (3/25/19) - Still working great. No complaints.

Newegg sells old models , incompatible with modern motherboards

Pros: None

Cons: Not usable with a z390 motherboard

Other Thoughts: Newegg sold this product in December 2018, but the product they actually sold was a 2017 model - of the same name. Newegg did not disclose that they were selling an obsolete model. This model is NOT compatible with 8th and 9th generation Intel processors.

Corsair further complicates the issue by selling a newer product with the same name and model number. There is no way to know you have an incompatible product until you spend hours trying to figure out why the cables don't match the motherboard pinout. There is tiny lettering on the box, that says 2017.

If you check a site like PCPartsPicker, you can see that the 2017 model is not compatible with the motherboards that are currently being sold. It's dishonest for Newegg to sell this without clearly stating that it is an old (and obsolete model).

Don't buy it - and beware of Newegg.

Hi Craig,

If the item was out of stock, I can see how it would have taken long to receive. Otherwise RMA's are pretty straight forward, you send yours, we send a new one. We are sorry you are unsatisfied. If you still require any assistance, please go to support.corsair.com and fill out a ticket and a Technical Support Specialist will contact you.

Thank you,

Excellent Power supply

Pros: I purchased one of these (750W version)about a year ago and its worked perfect. My system is on 24x7 and its been running for 18 months. It runs cool, fan rarely turns on. Also Electrically this power supply doesn't generate any sort of RFI that can interfere with amateur radio stations. I'm a Ham, and my previous power supply was so noisy I couldn't use the 40 or 80m band as it was interfering with my radio. This thing is as quiet as a mouse. Also since it runs so cool and the fan doesn't kick on, you get less dust inside your computer case gumming up the fans and motherboard. Well worth the money in my opinion

Cons: none

Other Thoughts: I'd buy this all over again if I needed too.
