Experience: 2 Years
I keeps my box neat and streamline. No loose cables.
I bought the 620, I should have gone to the 700 for the multiple cards. Didn't plan ahead. Live and learn.
Recently PSW died after a mem swap. Went thru the corsair website for RMA, did the troubleshooting with the online system. ended up with an RMA# and instructions. BOOM. 3 weeks later I have a brand new PSU. No questions.
I have to give huge props to this unit and corsair. they stand behind what they sell. rare especially for PSU companies.

Experience: 1 Years
-Modular and came with a pouch for storing unused cables
-Reliable and Quiet
-Matt black finish and came with matching screws
Got it when it was on sale but forgot how much I paid. I have always stick with Antec in the past and discovered their quality isn't so great and bad customer service. Purchased this to replace the power supply that came with Antec Sonata 2 Case. Same problem with another memeber that the the Antec power supply started to give sign that it was leaking power (a high pitch noise even when not turned on) This Corsair power supply is quiet, reliable and love the matt black finish. No problem so far. Corsair is known for making good quality ram and PSU.

- Reliable.
- Modular cables.
- Plenty of included cables.
- Inaudible.
- Had leftover "non-modular" cables.
I purchased this power supply for use in an Antec Nine Hundred and it's been great. There's plenty of modular power cables included in a neat pouch. One of the best features is that it's almost inaudible. Overall, an amazing product.

Experience: 4 Months

Great power supply
Found none so far
I've had this for four months and this was my first modular power supply and I loved it. I got it on sale so it was $130, seems a little pricey now. I intend on using it with 2 4850s, but so far it's done its job very well.

Experience: 2 Weeks
 Verified Owner
High quality
I'm not really sure where this PSU stands in the market when the HX750w can be found for cheaper. Perhaps this PSU is of higher quality than the newer, higher wattage HX series? I can't be sure. I got this because it was on sale, and all the reviews seem to be very positive.

Experience: 4 Months
Very silent
Attractive look
5 year warranty
Could use more pci-e connectors
Have had this PSU for 4 months now and don't regret purchasing it. Using it to power a core i7 build w/ 2x 4850's.

Experience: 1 Years
Extremely reliable power.
Easy installation and good build quality.
Was able to OC my hardware powered by this PSU.
None to Report.
I've had this Power Supply for around a year now and it's been rock solid. Haven't had any problems, so it stands as a great product.

Experience: 8 Months
Modular design, dual PCIe, lots of SATA connectors
first unit came with a bare wire - RMA'd
Got bundled with an EVGA 9800GT. The first unit had a bare wire - NCIX has excellent customer support! The power supply does a very good job, and their rebates worked.

Experience: 5 Months
 Verified Owner
- Stable rails/voltage
- Modular
- Sturdy/quality construction
- Silent
- Corsair is good with MIR
- Not certified 80+
This PSU is powering my Q9950 - 4gb of DDR2 - GTX260 (all overclocked) and doesn't show any signs of weakness.

Great purchase, espcecialy on sale with MIR !

Experience: 1 Weeks
 Verified Owner
Quiet operation, very stable power
none so far
Bought this to power a cpu q9550 oc g 3.2 with a graphic card HD4870 + 1 Wd velociraptor 300G and 1 Wd 640G.
Must said it's truly quiet seems to work on idle all the time never seems to be on a rush, wiring is more then enough for case like Antec P182

Comment: Amazing supply - 720watt max output, quiet, very clean DC current. One of the best supplies you can buy! BTW Hardware Secrets is one of the best sites for true PSU testing.
Posted by: IC9 @02/22/08
Comment: With the HX620, Corsair has had a winning product for more than a year and it has once again shown that it has every right to be at the very top of your list if you are in the market for a 600W to 700W power supply. Over the past year, the HX620 has only become more appealing with a reduced price an

Comment: TechReport's review, compared to 10 other PSUs. Corsair is Editor's Choice. It doesn't have 80+ certification but gets over 80% easily anyways.

Posted by: Nicolas_R @08/31/07
Comment: Wait a sec... Doesn't CORSAIR make memory? Well, they do, but now they do Power Supplies too! CORSAIR's latest entry into the power supply world known as the HX is all business. Without any flashy LED's or chrome, just what could make this power supply special? Let's find out!
Posted by: FirewireX @08/23/07
Comment: A great power supply, incredibly stable, and modular too. Corsair has a winner with the HX620W power supply.
Posted by: JMicahG @06/06/07
Comment: What happens when you put Corsair’s 620w power supply in an oven as hot as your computer case and then see how it works? If you are looking for a new PSU, put Corsair's on your short list.

Posted by: Ryan_V @03/15/07
Comment: Having mastered every aspect of the memory market and ventured successfully into the water cooling sector, Corsair has turned their attention towards power supplies. That's good news for buyers, because rest assured that anytime you see the Corsair logo, you can bet it's a high quality product backe
Posted by: Jonathan_N @01/27/07
Comment: What's most impressive is that the HX series came out of nowhere, and then proved to be a huge winner. Besides the obvious performance highs, there are a few other things that help this add up to become a highly recommended product. I am not a fan of bling. I don't care if a power supply has fanc
