Features [ Edit | History ]


Extending Corsair's legendary reputation in performance and quality, the new Corsair VX family of power supply features the industry's most efficient power management and ultra-quiet design for mainstream users. Unlike most power supplies in the market, the Corsair VX incorporates a single +12V power rail that delivers continuous power under heavy loads. This conservative design ensures reliable operation in today's most demanding system configurations and adds compatibility for future platforms. The unique combination of rock solid performance and incredible value puts the Corsair VX family of power supplies in a class of its own. Ideal for home theater PCs and Energy Star PCs, the VX line maximizes energy savings and minimum noise generation thanks to double-forward switching circuitry design.

Low noise, high efficiency, warranty
This is a great value power supply on sale or price matched. Extremely quiet up to 250-300W loads and very efficient even at low loads. My HTPC with Core 2 Duo, GT240 and a couple of 7200rpm drives idles around 70W measured using a kill-a-watt.

Absolutely no complaints, and I'm going to buy another one for a storage server.

Highly recommended for HTPCs, very quiet fan, solid design, great warranty
Not modular, fan does not turn off under low load like other (pricey) PSUs
Using this for my HTPC build. Would have liked a modular PSU to help with cable management and airflow, but this is a solid, reliable, well-backed PSU that I got for a good price. I seriously considered getting a fanless PSU, or one that shuts off the fan, but they are much more expensive and when you are watching bluray action movies you don't really mind the fan.

Experience: 1 Years


very quiet, high quality reliable unit
mail in rebates
Its been powering an Intel Core 2 Quad Q9550, iGP motherboard, and 2X1TB hdd office server 24-7 for the last year. Most people have to put their hand over the big 200mm top fan on the mini P180 case to believe the system actually running.

Efficient (80+)
5 Year Warranty
Little higher cost
Not Modular
Bought this power supply for a low-end file server. Runs great and is energy efficient.
It is a bit more expensive than say an OCZ or Thermaltake - but it's actually 80+, even though they don't specifically say it's rating.

- Good cable length
- Good quality
- None
A very good power supply, another great from corsair. It is a solid product and very realizable. Will buy again.

Well-packaged, Good-quality construction, Extra-long/Sleeved cables, Japanese capacitors
Not modular
Bought this for a budget Home General Purpose PC. Good product for the price. Cables are extra-long, and sleeved (which is nice). The unit is quiet, and hasn't produced a hiccup since!
Good PSU for a budget build.
Would buy again.

- Silent!
- Beatiful
- Enough power for a low-end system
- None
Corsair really makes some impressive pieces of equipment. This power supply is no exception. It is virtually silent, high quality and deliver enough power for a low end system. Highly recommended for small builds.

Great power savings! Reduced my system from 200w to 150w
update d my 6 year old HTPC system to try to improve power usage. I was amazed to see a 50w reduction, which will translate into almost $50/year - the update  will pay for itself in a little over a year!

- Very quiet
- 5 years warranty
- cable long enough for tower with bottom PSU (Antec 300)
- rebate is a Mail-in-rebate (but it always worked for me so far)
This is my second Corsair PSU I buy and I'm still very satisfied ! I was looking primarily for a quiet PSU and this PSU is the most quiet active component in my build. The cables are long enough for an Antec 300 with the PSU on the bottom.

Experience: 2 Months

- super quiet - perfect for quiet builts
- excellent built quality
- 5 year warranty
- temperature controlled fan
- not modular
- could be a little tight for bottom psu cases
The review articles for this model on the computer hardware review sites are excellent. Quality components and output among the most stable. This unit is manufactured by Seasonic, which makes this my third Seasonic unit. The other two have given me several years of quiet, stable systems.

Comment: If we could summarize this power supply in just one word it would be “wow!”. Together with Antec EarthWatts 500 W this is the best power supply up to 500 W we have ever seen...

Comment: "Legit Bottom Line: The Corsair VX450W is a highly efficient 450W power supply that can easily handle today's dual-core processors and is ideal for HTPC where silence and efficiency are key."
Posted by: Pier-Luc_G @01/22/08
Comment: It is not only quiet but also very efficient, claiming our number one efficiency spot with over 83%. So aside from having a quiet, stable, cost efficient system you are also helping to save the environment. Should the unit break some day, Corsair's 5 year warranty will ensure you get a replacement f
Posted by: Zenphic @09/09/07
Comment: The VX450W delivers clean, stable power that's much more than adequate for the vast majority of PC systems today. Like the HX series, it's among the quietest fan-cooled PSUs we've tested.

Comment: The Corsair CMPSU-450VX is reviewed and receives a good recommendation
Posted by: stoanee @08/15/07
Comment: Now, when people in the forums ask for a good power supply that doesn't have to be modular and they have a sub-$100 budget, I know I can steer them towards the Corsair VX450W.
Posted by: Shiu-Ming_T @08/14/07
Comment: With good DC output quality under almost all circumstance, good efficiency, low noise, and plenty of power for most midrange systems the Corsair VX450W is a value product ( $79.99+Shipping & $79.90+Free Shipping ) with premier product performance.
Posted by: Shiu-Ming_T @08/14/07
Comment: It's with this in mind that Corsair has introduced its new VX range of power supplies. Coming in 450W and 550W variants and claiming over 80% efficiency across the complete range of load levels - not the 80% at full load many makers will quote - it sounds like it could be just the ticket.
