The unique combination of rock solid performance and incredible value puts the Corsair VX family of power supplies in a class of its own.

great value for video gamer
a bit expensive
Got this 3 , 4 years ago for pc gaming, used it with GT9800, GTX260, GTX460, and now GTX570 and is still running strong. Highly recommend for entry level pc gaming setup. It is slightly expensive at regular price, but when on sale it is worth every penny!

Experience: 6 Months


powers everything needed in a budget gaming system
no modular
good psu, havent had any problems surface

Experience: 2 Weeks


good price
used to power an old system with amd x4 old cpu, ddr2 and low end video card for a workstation does the job very well, i mean it's not like a $500 powersupply

-Price (59.99$ on sale, with free ground shipping for entire order).
-Quality power supply, won't explode after a month.
-Looks pretty neat in my case.
I was looking for a cost-efficient power supply for a mainstream gaming computer I was building. The VX550W was an excellent choice at this price (59.99$), as it's a reliable power supply and it supports pretty much anything (other than 400+$ GPUs, I suppose).

Quality PSU
Pretty Quiet
Bought this to upgrade a friends old computer, was enough power to handle an older 3870x2 that i threw in his pc to give it some life. No problems, Got it on special even better deal.. he is happy that was the goal. For PSU always buy quality.

Good price at $70, low sound from fan, no problems with system.
Wattage too low if I wanted a second video card in this system.
This power supply was reviewed as a solid unit with considerable upside to it when it had come out new. It has been on the market long enough that this wattage is beginning to be insufficient for the power user systems, but it works for me with an Intel i7 2600K (slightly overclocked), 16 GB RAM at 1600 Mhz, ASUS GeForce GTX560 Ti 448CORE, SSD drive, SATA3 drive, 2 optical drives, and 4 fans from the case operating. I am very pleased with my system and this power supply has not caused any troubles to date.

Great quality, great packaging, silent.
none so far
This is probably the best bang for the buck. I bought this for 60$ and it runs perfectly. The packaging is on par with their professional HX series. Both have the white bag to cover the PSU and both came with ties and the Corsair sticker. Runs silently.

Experience: 3 Years


Solid power, quiet, runs cool, great warranty
I'm just about to replace this PS with a new one because I need one with at least 650 Watts for my new GPU. I thought I had better write a review first. I've had this thing for 3.5 years, running 3 different builds, overclocked two different CPU's and it's been an absolute trooper. Always trust Corsair products. It's always been quiet, cool and steady. Sad to see it go. Buy this PS for any situation unless you're running more than one GPU.

Very good Sleeved cables
Good length for mid tower
Runs very Quite
Price when on sale
None at all
Picked this up for $60 with pm to replace my toast coolermaster psu that was making a high pitch noise, First off I love this power supply the price to performance is very good. I was able to do a lot of cable management with the long cables, the sleeved cables are gone very well. Runs cool and quite. Recommended to any who needs a mid range psu for budget build.
