CORSAIR CMPSU-400CX 400W Compatible with Core i7 Power Supply

Comment:
Built by Seasonic, quiet, efficient, sleeved, black, cheap. It doesn't get any better than this. The ideal PSU for any basic build.

Comment:
A power efficient, high quality power supply from Corsair. I got it for $27 from the sale and PM'ing.

Comment:
This power supply is great for a budget build. 400 W is enough for must of the build. You can feel the built quality of this product out of the box. Will buy again.

Comment:
This power supply is ideal for a non-gaming rig and for someone who want the best quality. Ideal too as a replacement in older rigs, as this power supply can easily power older video cards.

Comment:
great power supply for the right price comes with a array a different style cables to suit your needs.quiet and has a nice big fan on it.

This is my first Corsair PSU, although not my first Seasonic, who apparently makes them. I got it as a backup PSU and was looking for a reasonably-priced one that could fill in in a pinch for a couple of 500 watt units if needed. This one seemed to fit the bill and I grabbed one on sale for about $50. There was also a $15 rebate offered, and if it goes through I'll only have paid $35 for it. After having received it, I'd say that was a bargain.Although I didn't see it specified anywhere here, I was pleasantly surprised to find an 80+ certified logo on the box when I received it. I don't like reviews that rave on about the packaging, but I would like to commend Corsair for one thing I've never seen before: the box has pictures along one side of all the connectors, and how many there are of each. Wish everyone did that.Inside here's what you get (or at least I did), in addition to the PSU itself: A user manual, a power cord, a wide adjustable cable tie, 10 small cable ties, 4 black mounting screws and a case badge. Pretty complete for a lower-end unit.The unit itself is largely plain matte black, and all cables are meshed. I particularly like the molex connectors with the easy-pull design. They're practically a treat compared to the old molex plugs. I've actually had to use pliers to get the latter ones off on occasion.In operation it was very quiet, in fact I had to stop and listen to notice it at all. The cables were all sufficiently long, for use in an Antec 300, anyway. There's not much more I can say, After taking it for a test run, I put it away again and it will only be called out if needed, so I can't comment on any longer-term use. But, if you want a good, seemingly well-built PSU for somewhat modest system power requirements, I think you will be hard-pressed to find better value (taking into account sales and rebates).

These units are great. They are basically Seasonic 400w (80 plus models) on the inside, but have a great matte powder coating on the outside, in comparison to the boring gray Seasonics.Like all Corsair PSUs, they're quiet; you won't be able to hear this over your other fans for sure.

sleeved cords! quiet fan! dependable power! affordable price! works wonderfully alongside a radeon 5770 1gb and i5 750

Ive bought quite a few of these in the past, and have 2 of them running in my systems. One in my data server one in my backup server. Great low wattage PSUs. They do everything I want and more. Would definitely recommend.

Quality is great. This fan isn't very loud. Cables are long, perfect for a large case, not the best for smaller case This review was modfied by poster @ 02-11-10 07:22 PM

I purchased one in Novemver as part of an HTPC build for a colleague, that unit was DOA. It was most likely an issue with the ATX 12V connector not providing any power at all. "No big deal", I thought. I have used numerous Corsair products before and understand sometimes DOAs happen.I bought a second 400CX locally to complete the build while the original unit was sent for RMA. This time everything worked fine, or so I thought. I completed the build and verified that the system would post. I began the install process for Windows 7 and was content to leave it going overnight. I returned 5 mins later to the smell of burning rubber and billows of smoke from the computer.One of the UNUSED molex connectors had burned right through it's shielding and sleeving. Needless to say, if I had actually left and not returned 5 mins later, there would have probably been a fire.Build specs, this is very light system:Gigabyte GA-MA785GMT-UD2HAMD PHII 955 no OCGSKILL 4GB DDR3Seagate 7200.12 500GBAntec Mini P180Artic Cooling Freezer 7 Pro Rev.2I still believe that Corsair makes great PSUs, but after these issues, I cannot trust the 400CX.

Another excellent psu by corsair. I have an HX520 which has been running flawlessly for 2 years. I bought this on sale for my secondary backup PC and it's perfect. I don't need high output so 400W is more than enough. It runs cool, silent, and has plenty of plugs. It comes with zip ties to organize your cables and a case badge.

Comment:
Great, high-quality power supply for the price. The build quality and the components used inside the PSU aren't as nice as the VX 450W, but it is not at the same price point as the VX. The CX is excellent for those who want to spend as little as possible for a reliable, high-quality PSU.

i use this psu in a budget computer and it got more than adequate connection. i really like how most new psu cable are sleeve in black.

Comment:
Got this one one on sale for $30 after mir with free shipping. Awesome deal. This is the nicest PSU i got so far, with Seasonic 380W coming close but gotten at twice the price.I'm impressed with Corsair build quality, all cables are long and sleeved, plenty of connectors. First-time experience with Corsair and a great one. Recommended.

Very satisifed with this product, high quality construction & flawless operation up to date. This is a great unit for smaller machines

Comment:
Excellent supply for the money - bought this for a office PC. I also have the amazing Corsair HX620W for my gaming PC.High quality design/build (Japanese capacitors/over speced components).Cables are nice and long and fully sleeved. Quiet 120mm fan that is speed controlled via temp.

Comment:
Even though you will end up with a nest of spare wires tucked into the CD expansion bays, I believe it is better to have expandability on hand than having a shortage of connections. great power supply for $35 After MIR. runs very quiet .

Comment:
As always, Corsair makes absolutely perfect PSU for any computer Enthusiasts. This is the third time I'm buying their PSU. For more info about this PSU just search reviews on internet. Overall great product, will buy again.

Comment:
Corsair makes great PSUs. This one is no exception. It's quiet and reliable. Wires are sheathed to reduce the clutter. The only weird thing was that it came with a European cable.

Comment:
Compared to the more expensive ones that carry 5 years, this entry level only carries 3 years...and only half the PSU uses Japanese caps while the other half uses Taiwan caps...but that's what you will get for an entry level.I'm running on this and there is at least 200+ W of headroom:CPU: AMD Athlon II X2 250 3.0ghzRAM: 2x2gb G.Skill F3-10666CL9D-4GBNQ DDR3-1066Mobo: Gigabyte MA770T-UD3PVideo Card: Sapphire ATI Radeon HD3650 512mb DDR2HDD: 250gb + 500gb Western Digital / 1TB Hitachi 7K1000.B

It's running a GTX250, 2 fans, 1 HD and 1 Rom. This machine plays alot of Call Of Duty, Brothers In Arms so I'm going to say it's been a great budget purchase. Obviously there's sales that could get you something more efficient but in a pinch I'd buy this one again!

Comment:
I was very surprised how quiet this PSU is. I was expecting that it would be a lot louder since it is so affordable. I would recommend for any econo-build.

This power supply fit very well in a Compucase 6K28BS. Hiding the cables was difficult, seeing as there were many, but it was manageable if a free 5 1/4 inch drive bay was available. It was paired with a budget build, a Gigabyte GA-MA74GM-S2 and an AMD 5200+. It powered fine and was fairly quiet, though not silent. Its noise output is slightly lower than the Antec EarthWatts 380W. Black meshed cables and finish look awesome. A very good buy for a low-end to mid-end build, given the low price and good quality control of Corsair.
