Interesting to see that Corsair hasn't updated their website with a news release. With the HX520 @ $70 AR I would like to think the 450W would hover in the $60 range to compete with the Antec Earthwatts.

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.

I wonder if they are still using Seasonic as the oem.

Seasonic OEM? Prolly. Corsair has done very well with the HX units.

It won't be long before we see pictars of them with their hoods up.
Seasonic produces their own PCBs with the logo big 'n proud.

Nice snag!! PurdueRY!!

It`s rare in these days that a company would expand there PSU line downwards as far as total watts are concerned...

yet notice the Amps are very strong!!

Who knows what the trend could become!!

Nice post!!:thumbsup:

If you notice the color scheme makes sense:

green, yellow, orange, red

Yes, they are Seasonic provided.
Well built too, I might add.

 

[Wicked Akuba]

That's really nice. I believe it will be shipped to Lithuania. So far Corsair had just 2 PSU's.

Are they still modular?!

No but they will not cost as much as the HX units.

That's because they're not released and that information wasn't supposed to be leaked.

metro's thread at XtremeSystems was deleted when he leaked this.

The HX520W's are cheap AR to help motivate revenue while expenses go into positioning these new products. Don't expect the HX520W to stick around with a rebate on it after these are on the shelves next week and don't expect these to be cheaper than the HX520W is now with it's current rebate.

GY, any input? Proof reading? I go live at 11 EST.

Looks like, if you're in the market, buy now or forever hold your peace. Thanks for the head's up!

Here is one review of the 450W http://www.jonnyguru.com/review_details.php?id=125

That's 1 sweet power supply if you ask me. You get all the pro's of corsair/seasonic made psu's, dont pay for watts you don't need, for a pretty good price. I also like the power supply, simply because it doesn't try to force ridiculous high wattage units on people.

I wonder what the 550W version is gonna cost and how it's going to compare to the 520hx.

 

[Modelworks]

Now if they could just make supplies that can output the full load for each rating instead of the fine print (combined) crap.

I hate how the psu industry has gotten stuck on this.
When I was designing psu's we never were allowed to get by with things like that.

Look at the 450Watt.
They show it as 33A @ 12v or 396W.
That means if you use the full 12v that you only have 54 watts left for the rest of the voltages.

Come on companies, just design the supplies properly and quit cutting corners.
That would be a great supply if they cut out the combined crap and made it as a supply that could ouput 550 watts continuous.

Its like a car maker selling a car that will go 120mph, but only if you don't use the ac at the same time.

The VX450 is $79.99 + ship @ Newegg

Very nice.

I pretty much expected superbness, & yup.

i had the impression that the lower power allocation to +3.3v and +5v rails was part of the ATX 2.02 spec or something.

No offense, but take some time to learn how an ATX12V power supply works. It's not a "scam" and being able to put out 100% on all of the rails at all times is simply not necessary for a PC. You're lucky (or not, depending on how you look at it) if you even have a 5A load on the 3.3V and 10A load on the 5V at any given time.

 

[Modelworks]

No offense taken.
I know how the supplies work.
Like I said I used to design them and not for home pc systems, but corporate mainframes. Ever hear of a company called cray research ?

I didn't say it was a scam.
I said that it would not hurt the industry if they would just build in the rest of the supply and do away with the combined labeling.

The argument that you won't need even 10A on the 5v proves the point.
If noone needs even 10A on the 5v then why do supplies bother with supporting upwards of 20A ? Increasing the 12V amperage doesn't magically increase the amperage on the 5v, so why bother increasing the current ?

Its pure marketing.


Also, read on your site about recapping power supplies and not knowing why he had more ripple afterwards ?
sigh.
Someone needs to go back and study smps 101.
Pay special attention to high frequency and capacitor choices.

Nope.
The atx spec only states voltages .
You can supply whatever you want in current.


I just think the whole thing would be simpler for the end user if they would just build for the maximum output for all voltages at the same time.

So if I need 5v @15A or 12V @30A, I don't have to consider am I going to have problems with "combining" them.

They already have huge markups on power supplies so adding a few bucks to manufacture a supply that can do as stated above isn't going to make the price skyrocket.

There are a lot of marketing hype in the PC business. Maximum power output is also a function of temperature. It would help the average buyer if all PSUs sold in the US must be able to deliver 90% of rated output at the 12V rail with 50C intake air temperature.

Yeah that would be nice as well.
The thing is that changes like this aren't prohibitively expensive.
And most of the stuff they are doing with supplies isn't really new technology.
Its all been around for years.

Guess its all about the most profit and what they can get by with,

 

[SerpentRoyal]

You got it. Big profit margin in the PSU business. The noobs continue to fork over big bucks so don't expect any change in the near future.

The FTC puts an end to this garbage power game with home audio amplifiers many years ago.

IMO, that's saying the same thing.

The components don't cost much less (if anything) to make them lower wattage on the +3.3V and +5V and there's nothing wrong with having overhead.

I think you're giving Joe Enduser too much credit. I seriously doubt that anyone that's smart enough to know to look at the way the DC output is distributed is going to make the assumption that one PSU is somehow "better" than the other just because there happens to be a lot more power on the +3.3V and +5V. 99% of the people still just look at the total wattage output and that's it.

Maybe Cray has huge mark ups on their power supplies, but not so much in the DIY PSU market is there "huge mark ups" being made. Sure, a PSU yields more profit than CPU's or RAM, but the only person really making big money on PSU's are folks like Best Buy and Newegg that use them as a way to make up lost profits on other PC items.

You know, I'm trying to be nice and respectful. Is it too much to ask for the same back? You're welcome to "school" me. I'm no EE, never admitting to being one, and I'm always willing to listen to those who are wiser. But don't talk to me like I'm 5.

 

[GalvanizedYankee]

OKW recapping an Epsilon with high end caps in an effort to reduce ripple was good work even if there was a slight increase. I would rather have quality Nipponese caps inplace rather than the not so great OST caps Fortron uses on the secondary side. I believe that in 2000 hours time the Nipponese lytecs will offer less ripple than the OST after 2000 hours.

NOTE: For those that don't know...Epsilons and the units based on them go out of ATX ripple spec at full output.

Modelworks,
Buy an Epsilon, recap it, ship it to jonny with return postage and we will all be able to see the fine design work you can do. OKW is just a very serious home hobbiest that cut his young teeth on audio electronics. I trust his judgement.
