OverviewCustomer ReviewSpecificationsProduct Tour
All the fancy components you install in your system won't matter if you don't have a PSU that delivers clean, consistent power. That's where Corsair comes in with their 450VX. This single rail design can pump out 33A/396W of +12v power for all your power hungry components. Certified 80 Plus, this unit runs at up to 85% efficiency and 99% Active Power Factor Correction to provide clean reliable power to your system.

The PSU comes with extra long cables for use in full tower cases, making it easier to route cables neatly so they don’t interfere with air flow. All the cables are mesh wrapped for a clean appearance and reduced air resistance so your cooling fans work better.

Tech Level Tech Level: somewhat high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: Watt ratings are over used and abused and mean next to nothing in the world of PC's. Main consideration is +12V amps and this one with +12V~33A is up there with the more expensive PSU's. Has the quietest fan of 6 in my PC. "Thumbs up" for this product.
Cons: Can't think of any, time will tell but I don't expect any trouble with it.
Other Thoughts: This is replacing a 350W +12V~20A PSU to start a complete upgrade of current PC to a dual core CPU rig.

Low wattage with high amperage

Tech Level Tech Level: high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: Good value for a reliable power supply. This is probably the most clean and silent power supply straight out of the box I've owned. So many people mistake high wattage for what they need exactly. Look at your components, and see how many AMPs you need per rail not what the total wattage displays. 33amps on a 12v rail is just ridiculous; not to mention the 3.3v & 5v are at 20amps. I'm running pretty high end stuff with a 450watt PSU with absolutely no hickups. I'll list it below since I'm running out of space here. Also, this is an 80 PLUS PSU, which will keep your bill down for the cheapo Asians that we are. ;)
Cons: None
Other Thoughts: My parts:

- Intel Q6600 Quad-Core CPU
- Abit P35 Pro
- 4gb (4 DIMMs) Corsair XMS Dominator RAM
- 2x 500gb Samsung Spinpoint 7200rpm 16mb cache HDs
- PNY 8800GTS 320bit 320mb
- Samsung DVD/CD burner

All running off 450watts with no problems whatsoever. Don't be tricked by the gimmicks of high wattage PSUs.

Great PSU

white Reviewed By: RGCGFMT on 2/2/2010
Rating + 5
Tech Level Tech Level: high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: Heard a lot of good things about these PSUs and since I use Corsair RAM almost exclusively and have been impressed with the consistent quality of it, when I came into the market for a new PSU, I bought the 450VX. Great PSU. Runs very quiet and provides solid power and more than enough connectors for the mid tower case I have it in. Easily the best-quality PSU I've owned. Also, it's 80 Plus.
Cons: None yet.
Other Thoughts: Just ordered a second one for a friend's PC build.

Tech Level Tech Level: average - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: Easy installation, good clean power, no issues. Good efficiency and Corsair name were the selling points for me. Power bill has barely moved since switching from 4 year old laptop to new desktop.
Cons: None so far. Another stupid-buyer syndrome issue here, as I found the 450W stated was the minimum for my video card, when I thought it would actually have a high overhead. But the card and whole system run fine, even when pushed fairly hard.
Other Thoughts: Install was easy, chord management isn't too bad. Exudes quality throughout. Awesome purchase, I must say.
