Corsair 520HX vs. OCZ GameXtreme 600W

post #1 of 14
Thread Starter 
I see a lot of people starting to recommend the Corsair over the OCZ. Looking at the specs and price of both,
I am wondering why that is. Can anyone tell me? I put the differences in bold.

Corsair 520HX
520 Watts
3x 12v rails rated @ 18A
1x120mm Fan
>80% efficiency
Active PFC
Modular Cables
~$100

OCZ GameXtreme 600W
600 Watts
4x 12v rails rated @ 18A
1x120mm Blue LED fan
>80% efficiency
Active PFC
Standard Cables
~$100

So other than the modular cables, why wouldn't someone want the OCZ PSU over the Corsair one? Is there something I'm missing?

I rather have 1 12V line.. or 2 at most.

I prefer this nice Rosewill Performance series. Got good reviews at JohnnyGuru.

It's also very shiny and 500w @ 50$

I vote for the Corsair(surprise!). In essence it is a single rail, since all 12V rails can draw it's full 40A. The ribbon style modular cables are easy to route under you mobo and whatnot, and to be honest I'm sick to death of blue LED fans.

Can anyone verify this and/or provide a link? Both their website and the sticker on the PSU itself list it as having 3 seperate 12v rails rated @ 18A. Thats still good obviously, but that is a bit different than essentially one rail rated @ 40A.

I can see what you mean about the blue fan. I wouldn't really care if it had it or not, but I do have somewhat of a blue theme. I was mostly just listing it as a difference to be thorough.

Take a look at jonnyGURU's review:

Looking at the main PCB, we only see two points where 12V leads are soldered down. One labeled 12V1 and another labeled 12V2. For fun, I put a 30A load on the 8-pin EPS+12V connector. This should have tripped the PSU. It did not, which tells me that there is no OCP limiter set for this rail. I did the same with the ATX main connector and again the PSU did not trip. This demonstrates that if the two rails are in fact separate, there is no OCP (over current protection) on each rail. Outside of a few traces zig zagging across PCB, I couldn't find how even 12V1 and 12V2 are separate, but I'm going to give Seasonic (the OEM for the Corsair units) the benefit of the doubt and say that we seem to have two 12V rails here, neither with any kind of "limit" on them.

Isn't that BAD there is no OCP?

The corsair is a much better psu

Very VERY stable even at 100% load

The OCZ has turbulence once it reaches high load

I was actually debating the same thing today. I found both for 69.99 AR, and can't decide which way to go. Although most people do recommend the Corsair, not sure if it is just a bandwagon thing, or the OCZ isn't particularly good.
