     This is Corsair's first endeavor into computer power supplies, and for a first go, they're no doubt looking to make an impact.

     The box is simple, yet informative. Boasting the most important features, including the five year warranty.

     Inside the box, we are greeted by a manual sitting a top a large foam block. It seems that this power supply is very well protected from damage.

     Underneath the manual and inside the foam block, we find our power supply. The Corsair HX620W Modular power supply.

     Mounting screws and zip-ties are fairly typical accessories for a power supply, but this one also comes with a "Powered By Corsair" case sticker.

     Free from the plastic wrap, we can see that the Corsair HX620W unit is a standard 5.5" depth, has a 120MM cooling fan and a honeycomb exhaust grill.

     There is no 115/230V switch because this product is full-range active PFC.

 

     In the above photos, to the left, we see the main ATX cable, the 4-pin P4 cable and the 8-pin EPS+12V cable are all sleeved. The modular connectors are all five pin except for the two PCI-e connectors.

     To the right, we see the power cord manual and a black nylon pouch also removed from the box. Similar to the Enermax Liberty, the cables are all kept inside this nylon pouch.

     Above is a close up of the modular interface. The main ATX, 4-pin and 8-pin cables are fixed to the housing. The peripheral Molexes, SATA, etc. plug into any of the five five-pin modular connectors shown on the top row. The PCI-e cables plug into the six-pin connectors on the bottom row.

     It's unfortunate that the 4-pin and 8-pin are not modular, or are at least the type of connector that allows the user to break apart an 8-pin connector into two four-pins. One of the key selling points of a modular power supply is the ability to only use the cables you need. A user is not going to need both a 4-pin and an 8-pin power connector for CPU power, so the user will be left with the task of hiding either one or the other of these.

     A representative at Corsair informs me that a board that supports four way or eight way CPU's would have both a four pin and eight pin power connector, so having a separate 4 and 8-pin power connectors would be advantageous. This is true, but those SSI compliant power supplies also have more than one 12V rail supplying power to those connectors. So I'm going to keep this "feature" in the "I wish they hadn't done that" category.

     Inside the nylon bag we can see all of our cables. Much to my surprise, they are nearly identical to Ultra's FlexForce cables.

Type of connector: Corsair HX620W
ATX connector 20+4
2 x 2 12V connectors 1
2 x 3 PCIe 2
8-pin Xeon/EPS connector 1
6-pin Xeon/AUX connector 0
5.25" Drive connectors

10**

3.5" Drive connectors 2*
SATA Drive power connectors 7
Fan only connectors (12V only) 2***
* The floppy power connectors are accomplished by using a Y-splitter off of one of the peripheral Molexes.
** Four of the 5.25" peripheral/drive Molexes are on two very short cables: 12" X 6" Ideal for optical drives.
The other six cables are longer 21" X 6" cables.
*** Fan only connectors are on a Y-splitter.

     No sleeving necessary with these cables. They're all molded together and all wires are the same color. Because the wires stay together and stay flat, they're easy to hide underneath the motherboard, behind your drive bays and even if you can't hide all of them, they still look good.

     Some might find it somewhat strange that the main ATX and CPU power cables are sleeved (nicely, I might add) while all of the modular cables are... umm... "FlexForce-ish." The aesthetics of this might work fine for some people, but not everyone. Personally, I'm happy that there are no "un-sleeved" cables here. Those that visit jonnyguru.com often know that's a pet peeve of mine and is often a reason for a lower aesthetic score. Certainly, the mix and match of cables doesn't hurt functionality any.

     It certainly doesn't hurt the eyes to look at the HX620W. The housing is flat black, but features a striking red Corsair label. This unit would look great in a red theme. It maybe even worth the risk of voiding a warranty and swapping the fan out for a red LED fan.

     One thing on the HX620W that I don't think I've seen on other power supplies is a label on the outside that tells others what kind of power supply is inside!

     Now for a look at the ever important label...

Corsair HX620W
+3.3V +5V +12V1 +12V2 +12V3
-12V +5VSB
24A 30A 18A 18A 18A 0.8A 3A
Max Combined Watts 170W 600W 9.6W 15W
620W

     The Corsair HX620W claims to have three 12V rails, each capable of an 18A load.

     The combined maximum wattage for the 12V rails is 600W, or 50A. That's very impressive considering that's 97% of the power supply's total output capability of 620W!

     Now that we know what Corsair's claims of capability are, let's put the power supply to the test...
