Strengths: Ultra quiet,
Modular flexible cables,
Five year warranty
Weaknesses: NA
Summary: With aim of this PSU you can build silent PC, which will be able to run some seriously power-demanding applications - e.g. 3D-games :) This PSU can feed Quad-core CPU and 2 videocards, and still stay quiet. The only noise you will hear (assuming you have good heatsinks on CPU and GPU) is seek noise of your HDD(s)!
The modular sleeved cables ease the challenges of keeping the system tidy and aerodynamic for optimal airflow, which is especially important if you wish to maximize cooling with the slowest of fans for the lowest noise. To top it all off, Corsair offers a five year warranty, which is the longest for any PSU!
It's price seems high at first, but in fact it worth every penny!
Highly recommended if you would like to build power, but quiet system.

Strengths: Build quality. Modular cables. 5 year warranty!! Rock solid lines.
Weaknesses: None.
Summary: For any serious builder, the power supply is THE most important component- the heart of the PC is you will. Do not skimp on the power supply when you are spending 100's on the rest of your computer. The 5 year warranty makes this power supply a no brainer. I am running a evga 8600GT, Intel E4300, MSI Platinum motherboard, Maxtor SATA HD and various other bits and pieces and not once had a problem. There is a reason why this is rated 5 stars :)

Strengths: Modular cables, stable rails, quiet, SLI certified, appearance
Weaknesses: 2 sata cables, price
Summary: Great psu for mid range systems. It has quiet, stable power on all rails. The cables are long and maneuverable enough for larger cases like p180. It has 5 year warranty and price is getting reasonable. I has two 2 modular dual SATA power cables which may affect systems with large number of SATA drives.

Strengths: High efficiency (~80%), active PFC, auto 110/220V switching, modular connectors, dual 6-pin PCI-E, 120mm fan
Weaknesses: Price (but you do get what you pay for!)
Summary: Purchased this power supply after reading JonnyGuru's glowing reviews of the HX 520W and 620W. Since he really puts his review units through the ringer and rates these units 9/10, you really can't go wrong with them.
Installed into a CoolerMaster Praetorian powering an overclocked 8800GTS and Core 2 Duo E6420 (3.5GHz). The modular connectors are a blessing - much less tangle in an already dense copper jungle. The fan runs quiet and the higher efficiency is great (it's noticeably cooler running than the less efficient Vantec ION 460W it replaced).
Some folks have reported a slight buzzing with some units but I have not noticed this on mine and Corsair does back this unit up with great support (they offer to exchange buzzing units at no charge, if I'm not mistaken).

Strengths: Excellent expert reviews, modular, 520 watts, quiet and thermal controlled fan, attractive appearance if that matters. 5 year warranty.
Weaknesses: None to date.
Summary: 2007-05-03 14:00:41 I would add my firm agreement to the earlier reviews here, as well as the majority of feedback posted on major retailer sites. I researched this item throughly prior to purchase, being most impressed by an online review at a site focused on silent custom pc building with an extensive writeup about the two corsair power supplies, including thorough metering at various stress loads. This was very valuable as I do not have the technical background to perform such a series of tests.
Given the approval from such a thorough exam, numerous user experiences, and the listed specs, as well as the five year warranty, I feel this is a power supply that will juice all but the most demanding rigs with peace of mind. At 520 watts, and SLI certified, it seems future proof unless an uber-rig is designed that would need more power, but that will be the case with any power supply.
I highly recommend this product, it has set the bar high and met my expectations. I have experienced no problems with this quiet unit in the short time I have had it. It has ample power for my current needs and reserves to outlast my planned upgrades. The actual manufacturer of the power supply is highly regarded. The modular cables are great as they allow one to withhold extaneous cables that would interfere with airflow and cooling.
It is also attractively packaged and well organized with a carrier bag for unused cables.

Strengths: Solid construction, great finish, quiet 120mm fan, modularized cables
Weaknesses: None
Summary: I bought this power supply to power a Core 2 E6400 2x 8800GTS SLi setup and am extremely impressed thus far. Little to no voltage ripple, rails are WELL within +/- 10% specs and it doesn't draw all that much from the wall (measured with a Kill-a-Watt). As a bonus, it runs extremely quiet too unlike the cheaper, less efficient power supplies, which just throw raw CFMs at cheap components. Definitely consider this unit and don't cheap out on the power supply after spending hundres of dollars on other components.

Strengths: Modular cables, quiet, enough power for most people
Weaknesses: Somewhat expensive, no lifetime warranty
Summary: I bought this to build a new system using an E4300, probably upgrading to an E6XXX later. I wanted to have a decent PSU that would handle overclocking abilities and remain quiet and cool. This PSU does just that. It doesn't throw a lot of heat and it is very quiet inside my Antec Solo case. The modular cables are sturdy and allow you to have only the cables you need inside the case, avoiding the bundle of extra cords often stuffed to the side. Overall a great PSU.

Strengths: Very quiet, Modular power connectors, 5 Year Warranty
Weaknesses: Quite expensive
Summary: I got this power supply for about two and a half months now and have not had any problem with it. It is super quiet and this makes me super happy. I like its modular design and easy installation. Cables came with storage bag which is very useful.

Strengths: 80% efficiency, 5 year warranty, Quiet, Nice Modular Cables, Overall great power supply
Weaknesses: Lack of 8 pin connector for graphic cards like amd 2900xt
Summary: This is one of the better power supplies out there. Based on Seasonic power supplies, which is a good thing. Rails remain stable under load. Warranty is just wow, besides corsair I don't know who offeres 5 year warranty on a power supply. Packing is good, you get small bag to put away in it cables that you don't use.
New graphic cards from amd/ati have 8 pin which this psu does not offer. Though the 6 pin connector still works with these cards. Hopely in the future power consumption of graphic cards drops so 6 pin or even less can be used.

Strengths: Solid construction.
Easy to install.
Long cables.
Weaknesses: none.
Summary: The CMPSU-520HX is driving my new system, which runs about 6-8 hours/day for the last 3 months. It has been running very quiet with no issues since installation.
This PSU provides steady and reliable voltages. Installation is easy and clean because of the modular cables. Strongly recommended.

Strengths: Quality, modular cables, rock stable power delivery and ultra quiet.
Weaknesses: Maybe the price? But you get what you pay for.
Summary: I went to this Corsair psu, from an ageing Antec True Blue 485W. This, after reading tons of power supply reviews. Among them, a very positive one from "SPCR" (Silent Pc Review)wich are very troughout when testing stuff.
This psu have very long cables. No problems using this in my Antec P180B case, where the psu resides in a separate compartment / tunnel at the bottom of the case.
I love the modular cables! No more cable clutter. A thing you really appreciate when owning a Antec P180 case, where the cable routing is a bit of a pain.
The HX 520W also comes with a nice nylon bag for the spare cables. And you even get some black zip ties and a nice Corsair case sticker for your bragging rights.
As for noise, you must have ears like a bat to hear any noise from this psu!
I live in the quiet country side. So the ambient noise is very low. And I only have 2 X Noctua super silent, 120mm, 1200rpm fans in the case runnning at 850rpm ( 20 dba ). And a Geforce 7950 GT with a Zalman VF 900 CU cooler on low setting.
I have to remove the side panel, and put my ear close to the power supply to be able to discern it from the other fans in the case.
Looking at the rails, they are rock steady, even when the psu is under pressure, like running Prime 95, torture test for ex.
I have never heard the psu fan spin up, during the 2 months I have owned this beauty. So it does'nt seem to have any problems what so ever, feeding my overclocked AMD Athlon64 4000+, 2 Raptor hard drives, a Geforce 7950GT, 2 fans and dvd combo + a Creative X-FI sound card. Or maybe the fan is dead silent even at full throttle? Have'nt got a clue lol.
A combined ampereage of 40A on the +12V rails. Will allow you to pick even the most power hungry top Radeon or Geforce video card. So the psu should be pretty future proof.
The only competition the Corsair HX 520W may have, is the
PC Power and Cooling 510W. But I seriously doubt it's worth the extra cost.
I would give this psu more stars than 5 if it whas possible.

Strengths: Ultra quiet (my first impression), Auto detect 110/220V, Modular power connectors, Corsair 5 Year Warranty!, Plenty of cabling choices, also came with a nice cable bag to store your extra cables.
Weaknesses: Pricy, but you’ll get what you paid for.
Summary: After having read many reviews, I picked this PSU because of very low failure rate and high-efficient (high %-wattage) although it’s quite expensive. But I really satisfy because of ultra-quiet fan and modular design. With 520W and over 80% energy efficiency, you can add many components as you want (if you not going to build a high-end workstation/server).

Strengths: 520W, low noise, high-grade components & construction, 5 year warranty, good looks, Active PFC, modular cabling, SLI certified
Weaknesses: Price a bit on the higher side.
Summary: Matched my Cooler Master Centurion case perfectly. Is driving a C2D E6600 on a Gigabyte GA-965P-DQ6 mobo with EVGA 7600GT video card, four hard drives, two dvd-rw drives, two PCI cards and three case fans without breaking a sweat. The HX520 is very quiet compared to my previous Antec 400W PSU. Provides more than ample power for a mid-to-high end system. Highly recommended.

Strengths: Quiet
Weaknesses: None
Summary: Using for a Antec 900 case and e6600 cpu. This PSU being built by Seasonic has a reputation for durability. Extraneously, as a retired demolition man, I feel at home with the industrial look. I can't even hear the fan. Nice, clean installation easy with modular cables.

Strengths: Silent, efficient and modular. Perfect.
Weaknesses: None. For SLI get the 620W version.
Summary: The power supply is silent and efficient. It is built by Seasonic which gets great reviews at silentpc.com. The modular cables are thin and flexible. Minor gripe. Only the motherboard power connections are not modular. For the 24 pin connector it doesn't matter. This is needed no matter what. There is also two other non modular connectors, a 4 pin and a 8 pin one for dual socket motherboards. One of these will not be used and must be tied down out of the way. 5 year warranty! Who else has this? My case fans and hard drives are louder than the PSU. All this at a great price. Cheaper than an actual Seasonic.
