Huntkey Green Star 450 W Power Supply Review

LOL

Thanks for your support Paul!

Here you say 360 watt.
Yet you say repeatedly in other places that it is IDENTICAL to the [Dynex] Huntkey 400 watt that you pulled 437 watts from without ripple going out of spec.

Huntkey Green Star 450 W is in fact a 360 W power supply that explodes if you try to pull 450 W from it. This time we taped the test in order to prove our claims.

A limit is a LIMIT!

Label on the box clearly shows:
12v1 + 12v2 = 286w max
12v1 + 12v2 + 3.3v + 5v = 431w max
Total = 450w max

In the video it was at approx ...
12v1 + 12v2 = 293w [7w OVER max]
12v1 + 12v2 + 3.3v + 5v = 435w [4w OVER max]
Total max = 453w [3w OVER max]
... when it blew.

You can't rightfully claim that it did not survive up to the power stated on the label when you were OVER THAT on 3 different power LIMITS at the same time.

Now, I don't honestly think this unit is a legit 450 watt PSU and I don't think the result would be any different if you didn't go over the max power limits. But the fact remains, you DID go over the max power ratings and that invalidates the entire test.

By in large I think your PSU reviews are some of the best on the web but you've really lost it with this one.

Right... As if 3 W would make any difference...

As a rule of thumb all good manufacturers leave a tolerance between 10% and 20% over the labeled power rating for peaks.

You should study more before criticing.

Gabriel.

I tested electronics for the Nuclear Power Industry for 20 years.
My last two years before retiring from that job I was a QA Inspector.
I know what a 'legal' and proper test is.

Design tolerances are used to determine limits but in proper testing there is no allowance in exceeding label plate wattage or current limits.

A Limit is a LIMIT.
Over a limit is like pregnant. You either are or you aren't.
If you are over a limit the test is invalid. - End of story. No exceptions.

I don't realistically think 3 watts would have made a difference but that doesn't change the fact that twice you exceeded label plate limits and then called the unit bad based on that.

QA applies not only to hardware but to testing methods.

In my industry if you made such a mistake in testing your qualifications and certifications would have been revoked and you would have had to re-qualify and be re-certified before you were allowed to touch equipment again.

You aren't alone. Everyone does it with PSU reviews.
Johny Guru repeatedly tests PSU's to the ATX specs of the motherboard he suspects it might be used with vice the ATX spec the PSU was designed for.
That attitude erks me no end. It's just wrong.

I RARELY see Hardware Secrets make such mistakes but this one, to me, is an exception.
- The big problem is the way you handled it makes you look biased.

It might seem like I'm heckling you but the fact of the matter is I REALLY LIKE your reviews [best PSU reviews on the web if you ask me] and I don't want to see you get sued and go *poof*.

Cheating the limits (even if just a little) and then sticking it up on youtube was a really bad move. A judge isn't going to understand or care about tolerances.

Maybe you confused sites??? The JonnyGURU.com site uses a SunMoon SM-268 load tester the same one used on this site.

They also use the same Stingray DS1M12 from USB Instruments to test and record ripple.

I'm not confused. - I read both sites.
The gear doesn't matter when the method creates invalid tests.

Then could you point out in a review what you were saying about

"tests PSU's to the ATX specs of the motherboard he suspects it might be used with"

because I didn't understand that at all???
