Here is a snippet:
"HX620W (also known as CMPSU-620HX) is today the most high-end power supply from Corsair, delivering up to 620 W. This model features a modular cabling system, a big 120-mm fan and is EPS12V-compatible..."

Hey,

really nice "review".

Ok, it's more like an article about that PSU instead of an proper review, because of no tests been done..

Too bad you couldn't tests this PSU, because you haven't the right equipment..

PS: But one question remains, you wrote in the article, that if the manufacturer don't say at what degree the power or amps are tested, it is probably at 25°C.

But what is about the MTBF?! The MTBF for the Corsair PSU is rated at 100.000 hours, but there is no info about at what degree?
So is that only rated/measured for/at 25°C or at 40, 45 or even 50°C?!

Hi there,

No, they didn't post this info.

FYI: MTBF isn't a trusted metrics and cannot be used to compare products or even to measure reliability. Learn why here:

With regard to the "are there really three +12 rails or just two?" issue, there's only one. The review mentioned that the two +12V switches were operating in parallel, which means that there's only one +12 winding on the secondary, which means there's one +12 rail, not two or three.

In fact, EVERY ATX supply that uses a single transformer for it's +12 outputs (and I'd venture to say this is all supplies) has a single +12 rail. There are no "multiple rail" supplies in the PC business. ALL the "rail" definition is done as a wiring exercise to meet the UL requirement that no externally cabled circuit has an energization of over 240VA.

Unless and until you find a supply with separate transformers, switches, and feedback circuits for each +12 output, you can pretty much wave off the entire discussion of "how many rails are there?" There's just one.

Hi,

Thanks for you comments. Just to add that so far we've seen only one power supply with two really separated +12 V rails, that was Enermax Galaxy 1,000 W:

Hi Gabriel -

Wow, that Enermax is quite the supply. I wish I needed one, but then again, maybe I'm glad I dont!

I hope my comments on the multiple-rail scenarios weren't taken as criticism - the review of the supply was very informative. I only wanted to offer my perspective on the issue that you were also critical of.

Regards,
sluggo

Hi,

On the contrary -- you explained it very well!

Cheers,
Gabriel.

Just to let you know that I upgraded this article to a full review, adding load test results and minor updates.

Enjoy!

Cheers,
Gabriel.

great review

Any plans to review in a similar manner its little sister 520HX

?
I use a 520 HX since one year ago and it never let me down. Yet I'm curious how much might be pulled out from this little one, hmm maybe 600w?
I think my components are away from its 520w offering (E8500 + 8800GTS 512 +2GB Crucial + HDD Seagate + DVD RW Lite On all of them on a Dfi UT P35 T2R) but I would appreciate a similar top quality review for HX 520.
best regards, domogled, Romania

Hi there and thanks for your suggestion.

Usually we do not review power supplies from the same series with different wattage because they usually use the same project. In other words, the results are usually the same.

Thanks for the suggestion anyway.

Cheers,
Gabriel.
