Corsair has been making PSU since the second half of 2006...
They unveiled two appetizers to market, 520W and 620W PSU.
The performance and product specification is really great.
I knew some users take them to compare with Seasonic's M12 series.
No matter the spec and appearance, both of them have something in common.
Hence, I analyze them by a comparison.

Price is always significant to consume, so:
Seasonic M12 about US$148
Corsair HX520W about US$121
If you are the users who care about quality,
guarantee period and reasonable price, Corsair HX520W might be a better choice.

The Corsair HX520W Modular Power Supply
We take a look at the package first, it's a bit bigger than some "same-level" product.


The accessories from inside
Multi-language users menu and power cords (not in the picture)
Cables for power supplying


Corsair HX520W itself


The major heat dissipating system is the 12cm temperature-control fan.
The RPM is low when light loading. If in a heavy loading situation, the noise is still acceptable.


There is a cellular heat dissipating "holes" for a better heat-dissipation.
It is a "auto-switch", no need to put a 110/220v switch there.


12V x 3, up to 54A, 480W
That can support most of mid-range to entry-level high-end VGA,
which under SLI/ Crossfire mode without problems


A modularized sockets: 24/ 8/ 4pins

CPU:INTEL Core 2 Extreme QX6800
MB: DFI LANParty P35-T2R
DRAM:CORSAIR Dominator TWIN2X2048-8888C4DF
VGA:ELSA FALCOX HD260XT 256B3 HDT RH
HD:Seagate 7200.10 320G
POWER:Corsair HX520W Modular Power Supply
Cooler:Thermaltake V1


The settings under OS:
CPU: 333X10=>3333Mhz
DRAM: DDRII 1000 CL4 4-4-9
VGA: 2X ELSA HD260XT
The voltage of DFI P35 is a little low, that's because the power consumption is keep on.


OCCT is an useful testing software
In the test, it can make all the cores in a full-loading status

The variation of the CPU's voltage is more related to motherboard's design.
The performance is good if the voltage can reach 1.3 to 1.34V while all cores is full loaded.


3.3V: about 3.22 to 3.25V, the voltage "drop" about 1% only


5V: about 4.76 to 4.81V, also, the voltage "drop" about 1% only


12V: it sticks in 11.9V


OCCT is mainly for testing the voltage (3.3/5/12V) variations of CPU and RAM while under OS full-loaded.
For some minimal error of mobos or high-end VGA cards, it is not for it.

The PSU works fine with quad-core CPU and 2600XT CrossFire in a OC situation.
In the test,
The RPM of the fan is not high and the working temperature is acceptable too(around 40C) includes all the merits I introduced,
this PSU shows a high C/P ratio.

The coming up review of mine is the most popular Elsa 8800GT 512MB VGA card.
Then, I'll use Corsair HX520W PSU again!!

wait for ur elsa 8800GT review ,

its nice if corsair comes with bigger watt... then i will definitely buy corsair PSU...

They do have a new series now..

I think should be TX series..

520watt now day become entry lvl edi..
crosair should have send something bigger to windwithme to review

Yes, they do have new series now. TX series comes in 2 flavor - 650W and 750W. For me the older 520W is more than enough but if the price is ok, i'll get 650W for my new rig.

LOL...single rail for TX series if not wrong:)

lol..and vx is for entry level lo

quite interest to TX750w.... can get in malaysia ad??
wat price in LYP??

No new from my side yet...

But i think will be soon....

plzz... any update plzz post at here...

LOL..i will PM you then...
As no business talk here

LOL..why don't you write a review for us?
I know you have one

me organization skill very bad, so no point writing a review to confuse ppl

but the HX620 has been solid for me..and it's a very very quiet PSU even under load....

Yea..

My next target

See 1 month later, my current psu will be ready for sell again..

me too. a happy user and owner of a hx620

thx a lot... business talk u pm me,
but then u can post ur review here marr

I don't have one yet...~!~
Still hunting money for the 620W psu

Seem not bad wor...make me need to reconsider what PSU should I change...btw, if compare to Silverstone Strider 560w and 500W, which will be better ler? the Silverstone of course is cheaper lor...but in term of money value which will be better?

For your rig....ST50F would be more than enough.

Corsair really shows their quality. So, this is the link for the 650W and 750W, TX series. Tekan sini
and the HX series, click the emotion.

ic...but ST56F seem just few RM higher only...maybe should get ST56F though...but the modular of this HX520W attracting me too...hmmm...now need to think think liao...

ST50F should be RM50 cheaper than ST56F.

HX520W certainly a great PSU.We also have Mushkin 550W Modular PSU at RM3XX in LYN.

You will not regret after you c the packing of the HX series.....

Let me show how does the packaging different from any other manufacturer ..

I've opened many but may not used too many PSU .. but this is far one of the best PSU packaging I've ever opened. solid inside out ..



The psu was wrapped with a plastic bag and placed within this thick foam. Very secured as the foam is about 2cm thick and could absorb lots of vibrations or impact.







PSU specification, should be the same as the website as well.





All the cables needed, and plus side that I've got from this unit is it support 2 X PCIE- 6+2 pins which was absent in older batch. So I can run this PSU on my 2900XT with CCC over clocking enabled..

I didn't aspect this as most of the review out there were for older batch and it wasn't supporting PCIE- 6+2 ..

Great job by Corsair knowing what people wants..

Anyway the PSU is definitely silent and doesn't produce random buzz sound like some other PSU does ..

By far the most satisfied PSU ever used and definitely beat CoolerMaster and Enermax for sure..

Overall quality of the PSU and leads still can't beat Tagan coz it operates based on more flexible modular cables rather than thick rounded leads offered by Tagan.

Just for ur information both Tagan and Mushkin is made by the same manufacturer according to one of the staff at ATE shop... which is why both PSU features the same thickness and types of cables.

So both are solid but the Mushkin would be better deal as lower price.. it's another one that I would recommend after this Corsair HX620..

I chosen it due to it's modularity and flexibility of cables..

Thanks Doom for the review wo~

Oh ya, where is the corsair sticker:) As i know, there is a corsair sticker right?

After seeing all these...I am so tempting to buy the HX520 liao...got any bulk for it? or I can only get from LYP? hmmm...maybe I should go check it out at bulk area there...

hm..i think go for ST56F is better....Corsair and Silver Stone quality are same...i think
and silver stone is cheaper...

This post has been edited by 168257061: Nov 13 2007, 01:40 AM

I know...but HX520 is modular...ST56F is not modular...I am now using modular PSU...if can...wanna use modular one for the next upgrade...

Doom, u sure the Mushkin HP-550 a good choice?
even though it price around Rm330-350 (which is very affordable), the review is not convincing at jonnyguru.com

Do they bundle the 6+2 PCI-E power connector with HX520 or is it only reserved for HX620?

For me, i will go for Corsair...Modular

The benefits of modular is better cable management. However, I read that the disadvantage of modular is that the modular interface could be a weak link (if not well made) compared to direct cable from the PSU inside.

Yea:)

But i think those well-branded psu should be no such problem.

Corsair HX series is high recommended. So i think will not be a problem lo.

(Still Noob here )

anyone see this psu in lowyat?? have search it..but dont have luck in bulk section also dont have stock yet..

That's a very nice PSU, not to mention the price

but its still affortable fit well with small case

the PSU is available is several stores in LYP...refer my spoilers. you can shop around for better price...btw, my HX520 doesn't do PCI-E 6+2...so watch out if you are aiming for one...

Between OP650 and HX620, what does each of them have in advantage of each other and which would you guys choose over?

And when the Corsair PSU was released, many people had been complaining about them breaking down. Is this true or it does not exist anymore?

Breaking down? dunno got such complains. I've been using the HX520 for few months already
and so far so good. very stable + silent I decided to buy it after I read THIS REVIEW. And according to
the review also, Corsair is using Seasonic psu.

single rail VS multi rails. but i hope there'll be VX550 in malaysia.
