Corsair HX CMPSU-520HX ATX12V v2.2 and EPS12V 2.91 AC Power Supply

Excellent Power Supply

Strengths: Very quiet, Modular power connectors, 5 Year Warranty

Weakness: Quite expensive

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.

Top Quality Power Supply

Strengths: Build quality. Modular cables. 5 year warranty!! Rock solid lines.

Weakness: None.

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...

CORSAIR 520W MODULAR POWER SUPPLY

Strengths: Modular cables, stable rails, quiet, SLI certified, appearance

Weakness: 2 sata cables, price

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.

Super Power Supply

Strengths: 80% efficiency, 5 year warranty, Quiet, Nice Modular Cables, Overall great power supply

Weakness: Lack of 8 pin connector for graphic cards like amd 2900xt

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...

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.

Silence and performance galore!

Strengths: Quality, modular cables, rock stable power delivery and ultra quiet.

Weakness: Maybe the price? But you get what you pay for.

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...

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.
