Corsair HX CMPSU-620HX ATX12V v2.2 and EPS12V 2.91 AC Power Supply

Great power supply! Just one flaw...

Strengths: The claimed wattage is what it can sustain at 50c, not its peak at 25c like most advertise. The 12v rails are very beefy. This puts it in the same legue as PSs that advertise much higher wattages.

Weakness: When I first got mine, it made a loud clicking noise. Fan was hitting up against some metal on the inside of the unit. After being on for 10 min, noise would stop. This is apparantly a common flaw.

Used it for about a week before RMAing it, and even with the clicking, it was quieter than my old Thermaltake. Corair customer service is great, I got an RMA right away when I filled out a tech support form on their website.

Excellent 620W Power Supply!

Strengths: Corsair 5 Year Warranty! Super Quiet, Modular Design, Plenty Of Power - Industrial duty capacitors, Plenty of cabling choices included. Also Includes a bag to store your extra cables.

Weakness: A Little Expensive! Minor Cons Cables are fairly stiff & plain black in color. The EPS12V cable is not modular neither are the ATX cables. SATA power connectors are kinda of long between connections.

I am amazed with this power supply it has won me over when it comes to power supplies Solid Design, Very Powerful, running 2 7950 in SLI no problem with a overclocked FX-55. Solid 12V rails! User friendly modular cabling. Corsair 5 Year Warranty! Only other thing I could ask for in a 620W power supply is the price to be a little less and to have had the cables sleeved like the ATX and EPS12V...

I Would Highly Recommend This Corsair 620W Power Supply! 2 Thumbs Up!

Great Power Supply :-)

Strengths: 5-Year Warranty, Quiet, Modular Cables, Stable

Weakness: No blue lights? ;) 4-pin and 8-pin cable are not modular.

Completely overkill for my Core 2 Duo, 7900GT, single hard drive, dvd burner + floppy system. Will easily be able to power my next upgrades/build. Nice assortment of modular cables. Voltages are very good with little fluctuation(tested with a digital multimeter) though I wish the +5v was 5.05 instead of 4.95. I first installed this in an old Celeron 1200, 4mb pci gfx, single hdd, cd burner +...

I first installed this in an old Celeron 1200, 4mb pci gfx, single hdd, cd burner + floppy system just to make sure it wasn't doa and to see how well it would peform with a VERY light load. I was surprised that it was almost 10% more efficient than an older Forton 300w ps I had been using. Granted, it was using only 6-7 watts less power (measured using a KILL A WATT). If you have an older/low power system that needs a new ps and know you will be building a new rig in the future don't be afraid to buy this ps.

Strengths: nothing just modularized

Weakness: even doesn't turn on the motherboard i test that with ultra power tester it show even you turn off the back switch your +5 has on and cause damage to your motherboard

that's vest your time and money you can buy good one at this price.
in case your motherboard in danger, a big one
even doesn't turn on the motherboard
i test that with ultra power tester it show even you turn off the back switch your +5 has on and cause damage to your

One Year Update Still Performing Strong

Strengths: Robust design, quiet operation, modular cables, 5 year guarantee, smooth waveform output at load, etc.

Weakness: No problems whatsoever.

Great and reliable power supply for most mid range, and even high range systems. One notable reviewer drew 720 Watts on this unit with stable output, at 50'C. I like the modular cables keeping the computer case uncluttered. Despite newer designs out each month, I am going to purchase another one of these 620HX units for a new build. Do not confuse this unit with the newer Corsair 650W and 750W...
