Corsair Introduces New 450W and 550W Power Supply Units

Extending Corsair’s legendary reputation in performance and quality, the new Corsair VX family of power supplies 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. Each Corsair VX power supply is backed with an industry-leading 5-year warranty and 24/7 on-demand customer service.

Corsair VX Series Features:
  • Supports the latest ATX12V v2.2 standard and is backwards compatible with ATX12V 2.01 systems.
  • Ultra-quiet 120mm double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying the RPM in response to temperature.
  • Double-forward switching circuitry design offers maximum efficiency, up to 85% under wide load range.
  • 99% Active Power Factor Correction provides clean and reliable power to your system.
  • Universal AC input 90~264V automatically scans and detects the correct voltage. No more hassle of flipping that tiny red switch!
  • Dedicated single +12V rail offers maximum compatibility with latest components.
  • Over Current/Voltage/Power Protection, Under Voltage Protection, and Short Circuit Protection provide maximum safety to your critical system components.
  • High quality Japanese capacitors provide uncompromised performance and reliability.
  • 6 Serial ATA connectors
  • Extra long cables support full tower size chassis.
  • Standard ATX PS/2 size: 5.9"(W) x 3.4"(H) X 5.5"(L); 150mm(W) x 86mm(H) x 140mm(L)

These PSUs will def. be priced lower than the HX520W already out (which is roughly $90-100)

Do these have modualer cable support?

Also not sure if they're still planning on it but one of there tech support guys said they're gonna make a higher watt psu soon.

Why make non modular psus anymore? The added resistance of the modular cables is next to nothing, especially with the higher end ones used by kingwin and hiper that lock into place.

Is there some other reason?

33A and 41A not bad for 12v rails though I was hoping for something more in the lines of PC P&C. I love these though the HX lines are more than 85%.

VX550W has one PCI-E 6+2 pin extra that VX450W doesn't have, other than that their identical (not counting the 100W+amps). I'd like to have a modular PSU next, tired of all extra wires going everywhere, but these seem nice. 550w would be more future proof being pci-e 8pin compatible (hd2900xt), but it costs the same as HX520W.

Don't have currently EPS12V 8pin or pci-e 6pin plug that I'd need and current PSU runs hot. I've read that corsairs run hot too, so don't know if they are any better :/ So they'd basicly lessen electric bill and maybe run cooler, but cost 3 times more :)

Where did you read that corsairs run hot?, not doubting you, but prior to buying one i read a good 5-6 reviews and they all said they run cool & quietly (which ive found to be true, even running 8800's in sli)

Then we have this:

Fan just doesn't spin up -> hot, but quiet. Same as my current PSU, fan barely rotates and it doesn't spin up ever. Of course mine is really cheap and generated more heat due to low efficiency and cheaper parts.

But you having hx520w know better and you say cool&quiet, so it sounds good. Does the fan spin up when gaming? Seem like it should much sooner than these new ones:

I wouldn't mind PSU making noise then as long as it's no hoover. Currently my PSU heats up other components in my system and my room, downside of the quitness :)

edit: oh and you have quite a similar system, so I'm tempted to go corsair as well if it's been good. New versions should even have that 6+2 pin pci-e plug for future proof.

the fan spins up a bit, but its still very quiet, i cant hear it over the other fans in the system, but i see it spin faster

What he said. And to add to it, I can tell the fan does speed up a little, because much more air comes out the back of the psu, during heavy load.

Maybe all those complainers are coming from a low powered system, to a higher power one?

Mine gets a little warm to the touch after heavy gaming, not anywhere near hot. I tested it extensively because I was having a shut down problem that I thought might have been the psu. Turned out to be software related, man those few days had me pulling my hair out. lol

You got me convinced, time to start looking for cheap place for corsair. Those "Over Current/Voltage/Power Protection" & other stuff can't hurt either, don't know if this one has any xD

yes, they do, theres a link to a couple of reviews of the 450w one on the (tpu) frontpage, and the overvolt protection kicked in at 460w
For a value unit, the performance of the VX450W is remarkably good. The lines are very stable overall and do not ever fall outside their specifications. The regulation of the lines is quite tight and they stay steady enough when large load changes take place. While the unit works perfectly fine at 450W capacity, it will shut down within a few seconds if the load surpasses 460W even if it is cool at the time. We’d like to think that this particular unit is capable of more, but at least we know that the overload protection circuit of the unit works fine

My comment got eaten when it was first taken down...

The amperage on both models is great - the 550W should even run my PC, and the 450W can handle anyting less, in my opinion.
