1. Introduction

Today's needs for efficient and reliable power supplies are greater than ever. We all want to have a stable PSU that will also meet the demands of our current and future PC configuration. With already so many products on the market, Corsair's proposal at 620W, comes with many interesting features and good performance.

- Corsair HX620W Power Supply

The Corsair HX620W/HX520W power supply is the most versatile and robust power supply available in the market today. Utilizing superior triple +12V power rails and a whisper quiet double ball-bearing 120mm fan, the HX620W/HX520W is ready for tomorrow’s most power hungry components. The HX620W/HX520W conforms to the latest ATX12V 2.2/EPS12V 2.91 and RoHS standards, and delivers unparalleled continuous power to all of your critical system components reliably and safely. Corsair’s easily detachable and flexible modular cables allow you to use only the cables you need and enhance the air flow inside your system.

2. Retail package

For our tests, Corsair sent us the retail package of the Corsair HX620W Power Supply with part number CMPSU-620HX. Its retail price can range from US$140~160. The package is quite large.

Let's open the box:

The PSU is well protected in plastic foam.

The PSU itself is typical in size (150 x 140 x 86mm) and is certified for ATX v2.2 standard. There is a 120mm cooling fan in the base. The external black matt finish looks nice and the case feels solid. There are no sharp edges, so you can handle it without any worries of scratching anything.

The only cables that are initially attached are the:

The power supply specs indicate that it can be used for "heavy" use, in other words for SLI/Crossfire setups:

The rear of the PSU is honeycombed to help air ventilation. This design with the fan in the base of the PSU case, helps draw air out of the computer case and out the rear of the PSU.

There is a pouch that contains all the cables:

Removing the bag contents we have:

  1. 2 x 800mm 4-pin peripheral power connector cables with three connector heads.
  2. 2 x 450mm 4-pin peripheral power connector cables with two connector heads.
    Note: The 4-pin peripheral power connector is widely used on devices such as IDE hard drives, CD-ROM drives, optical drives, and on certain AGP video cards.
  3. 2 x 550mm PCI Express connector cables.
  4. 2 x 800mm SATA connector cable with three SATA connector heads.
  5. 1 x 650mm SATA connector cable with two SATA connector heads.
    Note: The SATA power connector is used on SATA hard drives or SATA CDROM drives.
  6. 1 x Y-adapter with a 4-pin female peripherals power connector at one end and two female small 4-pin Floppy power connectors at the other.
    Note: The small 4-pin power connector is widely used on floppy drives, and certain fan control panels.
  7. 1 x Y-adapter with a 4-pin female peripherals power connector at one end and two female 4-pin peripherals FAN ONLY power connectors at the other.
    Note: The Fan only power connector is strictly used on fans.

In addition, an AC Power cord, several cable ties and mounting screws are included


3. Tests

To test the PSU,we put our PC system through various benchmarks that put a load on the CPU and VGA card. Specifically, we used 3D Mark 06 v1.0.2 and burn-in tests with Sisoft Sandra 2007. Our test PC setup was as follows:

All PSU ratings were monitored with Everest Ultimate Edition v3.0. The following table lists the industry wide specifications for DC Output Voltage Regulation.

 

After running 3D Mark 06, the monitored outputs showed us how much the Corsair HX620W power rails had deviated. A summary of the results can be found below:

The results are very good. All ratings are within standards, while even at full load, the voltage only changed by 0.01~0.06V. The system is capable of supporting a high performance PC with even two VGA cards installed.


4. Conclusion

To be honest, we didn't expect the Corsair HX620W to perform as well as it did in our tests. While Corsair is famous for their memory products, they are not known for manufacturing power supplies, but their PSU line has achieved the same level of competence and performance as their memory, which has made the Corsair brand so respected.

The HX620W can support two PCI-E VGA cards in a high performance system, based either on SLI or Crossfire technologies. The modular, sleeved cables are perfect in both design and flexibility. The clever design will save room from un-wanted cables dangling uselessly in your PC case. Ah, I almost forgot, the 5 years warranty that Corsair backups this product with! And for SFF users, this PSU makes very, very little noise.

Overall, we have no reservations in suggesting this product to all users who want a good and at the same time highly configurable PSU for their system. Corsair HX620W can be bought at the retail price of US$140~160, which is on the high end, but it offers many excellent features.
