Pros: I've owned this PSU for 6 years now. It's never beeped, buzzed, clicked, or failed. I put it in my case (Antec P182) SIX YEARS AGO and it has worked flawlessly since day one, and every day since. Corsair and Seasonic truly assembled a masterpiece with this thing, I can safely say it's the best piece of PC hardware I've owned in my 25+ years of PC gaming.

Cons: Wish more of the cables (or ALL of them) were modular. I've had to wrap some of them in twist-ties and shove them on-top of the unit to get them out of the way. Only 80% efficient; barely Bronze. But it came out in 2006-2007 so I can forgive it for that. At the time it was the best PSU ever made.

Overall Review: When I bought this unit, the warranty was 5 years. Corsair has sinced bumped their HX warranties to 7 years, so hopefully I'm still covered. My friend is sending me his spare 620HX so I can keep using this model without having to buy a new PSU (and risk losing quality).

Pros: Modular cabling, 10 standard molex plugs, full 620 watts. Predicted lifetime is based on actual usage temperatures of 50C, not 20 or 30C like other brands which the powersupply will rarely be at. Turned my computer from unstable to stable. 430 watts wasn't enough. Also, why do so many people buy really expensive high end components and then a cheap average power supply?? If you underpower your components you will get tons of random bluescreens, seemingly unexplainable hardware and software errors (happened with me and a video encoding program, I looked online for a solution and so many people misdiagnosed the problem, blaming everything from memory, to CPU, to software when it is actually the power supply!) Corsair is top of the line. Well worth it.

Cons: none, you get what you pay for. NOT A CON (but I've run out of space in other categories) I had this thing under full load for the past 24 hours and I'm not quite sure what people are talking about but there is no loud noise coming from the PSU. I can't even hear it over my other case fans. Stays very cool due to high efficiency. The only possible thing to mention but isn't really a con is that the molex plugs have a rounded plastic clip thing on them. This is helpful for plugging into most standard molex plugs on most of the components in a pc, but my video card (X800 pro) needed a molex plug too, and the plug itself was so close to the card that the plastic clip got in the way and I couldn't plug it in without the clip trying to rip the power jack off the video card. So I just ripped one of the clips off, problem solved! Rock solid device so far.

Overall Review: Note: If you look inside this PSU and see a whitish compound strung (best word I can think to describe it) between components, especially the gigantic industrial duty capacitor, this is just a grounding compound. I have an AMD64X2 3800+, 2 gigs of memory (4 dimms), 2 optical drives, floppy, 4 harddrives, 2 other front drive bay accessories, upwards of 4 USB devices, relatively modern video card, and an X-fi. I looked up the power consumption for my PC on a website given the components, and it was 574 watts at peak load! I previously had an Antec Trupower 430, which is an awesome power supply but 430 watts wasn't enough. I needed a new PSU to do video encoding, which had previously bluescreened my pc repeatedly. If you frequently get bluescreens when doing high load processes like video encoding and have lots of components in your pc, chances are it's an underpowered system that's causing all your bluescreens. Get this power supply.

Pros: Working in desktop support for the last 5 years has taught me a thing or two about troubleshooting a PC. I thing that consistantly causes trouble with home built systems is a weak power supply! Avoid bluescreens, spontanous reboots, lockups and many other problems with the rock solid PSU. Runs my Asus P5B-Plus / 8GB Performance RAM / 2X 500GB SATA 3/GBs / QX6700 Quad Core Processor / DVD burner / Nvidia Quadro FX4500 like a charm! This PSU is a MUST for high end systems.

Cons: The PSU is not the cheapest but I say protect your investment! Don't spend $2000 on a gaming system and then throw a cheapo power supply in it.

Overall Review: The modular power cables are great! Say goodbye to a cluttered case. Only use the cables that you need!

Pros: People often overlook the importance of the power supply. The electronics in your computer are very sensitive and slight fluctuations in voltages can wreak all kinds of havoc. This power supply is rock solid. It has extremely stable rails, plenty of power for anything, and is silent. Plus its corsair, what more could you ask for?

Cons: Price, but you pay for quality.

Overall Review: I am running an Athlon 64 X2 6000+ overclocked, two hard drives, dual 8800 GTX's in SLI, a full water cooling system with TEC's, and this power supply runs it all with ease.

Pros: The Corsair unit is rated at 620W at 50 deg C continuous duty. All the other power supplies at Newegg.com are rated at 40 deg C. According to Seasonic's web site (the Corsair power supply is made by Seasonic), you need to reduce the rated capacity by 20% for rating it from 40 deg C to 50 deg C. Which means that at 40 deg C, the Corsair 620W unit would be rated at 775 Watts! According to Corsair's forums, this unit has been tested successfully in a quad-SLI configuration! Plus it carries a 5 year warranty.

Cons: None

Overall Review: The Corsair 620W power supply unit fits the LIAN LI PC-V1000BPlus II Black Aluminum ATX Mid Tower Computer Case like a glove. It seems that the Lian Li case was designed for this Corsair power supply.

Pros: It's blacker than black. Black enclosure, black fan, black cables, black screws, black connectors, black heatshrink wrap, and a stylish black bag to hold all of the black cables you're not using. It's very quiet and gets the job done. If you want a powerful, silent PSU for your gaming rig, without the chrome and LED circus light show, get this PSU. They also included a case tag, and stickers are always fun to stick to things.

Cons: I only had two gripes with this thing. If you want a PSU that's good for cable management (and you probably do if you're looking into a modular PSU) note the two issues below. 1. The 4pin for the CPU is not modular and cannot be detached. If you're using a motherboard that employs an 8pin 12v line, the 4pin will be sitting there with nothing to do. 2. There is no included cable that is just a single SATA power connector. There are only two SATA power cables that power 2 and 3 devices respectively. If you have OCD, it might slightly annoy if you have an even number of drives.

Overall Review: It's a PSU and it gets the job done. If you're looking for a modular, high-quality, slient PSU, you're not going to go wrong with this one. You might want to look at other reviews to get an idea of the longevity of this PSU, as I've only had it a short time.

Pros: Comes with everything you'd ever want/need. Cable bag is awesome. This thing has a lot more and is much more high-end than comparatively priced PSU's. It is advertised as having 2, 6-pin PCI-E connectors, but both have connectors for supporting 2 8-pin connectors as well. Corsair really did well.

Cons: Only reason I'm giving it 4 out of 5 eggs is that it can't really support the number of connectors advertised on newegg. It says it has 10xPeripheral (Molex) and 8xSata, but it can't do all those at once. It comes with these cables: 2 - molex x 3 2 - molex x 2 2 - sata x 3 1 - sata x 2 So thats 7 cables total, and it only has 5 jacks to plug in any of those cables. You get to choose which ones you want more/less of.

Overall Review: Even though I probably won't be needing more than it can handle, I am disappointed because one of the reasons I bought this PSU was because I thought it had many more connectors than similar models. I also don't like the fact that it was not clearly advertised.

Pros: Accurate power ratings. Cabling is extremely easy to work with. Connections are well made and easy to….we….connect. Running 8 hard drives, 1 DVD Burner, 7950GT video card AMD Athlon X2 and many fans. This PSU handles them all easily.

Cons: Floppy power connector could be longer. Doesn't work well with a DFI Lanparty NF4 Sli board.

Overall Review: Excellent power supply. In the last 2 months I have been through 3 PSU's and this one is by far the best. The OCZ GameXstream 700 was very disappointing to me. I was picking up noises through the PSU from my video card. I have NO idea how that can happen. I've also owned an AC Ryan moduler PSU and that was a piece of junk compared to this Corsair PSU. Take my word, you'll be happy with this PSU.
