^^I've seen that before. It's got to be some normal 80+ Certified PSU, and when Huntkey gets criticized, they'll say that "80+ Platinum Certified" is part of the name of the PSU rather than a reference to efficiency certification.

Edit: I'm surprised they show an image of the insides. I think that might be a Chemi-Con primary bulk cap, cannot tell. Too small. If so, I'd be legitimately surprised.

Hey, what if Huntkey is like "let's ram all the competition and actually produce something nice for a low price, and we'll end up making more money by selling a ton of them rather than getting more money per unit"?

Edit: Yep, that's a Japanese cap. But those secondaries with the yellow on black don't look it to me. But honestly, this may end up being the best $40 unit on the market if actually done right.
 


Not really. If his system is pulling 326w, then a 750w unit would put him squarely in the 40-60% range that Gabriel Torres and others indicate is the most efficient range to be in for power consumption and heat. A 750w Platinum or Titanium unit would provide the most efficient configuration for that nearly, or usually, 24/7 system.
 


That's not system consumption, that is card consumption. The rest of the system will make probably 500W.
 
Maybe someone oopsed on the price? The regular price is arguably a bit steep, maybe they were aiming for $69.99? Next key up on the number pad...

Only thing I see wrong (and it might be a copying error) is they claim it's single rail 42A, but the specs page says it's got 2x rails, 21A & 22A. Haven't read the review yet.
 
@Logain. What CPU did you end up going with and are you overclocking it?

@Turkey, even at 500w, a 750w unit barely misses the mark at 450w being 60% usage, and that's assuming the rest of the system is using an additional 174w, which is unlikely.
 

Something's fishy. Take a look at pics #3 and #5. One shows nicely sleeved cables, and the other does not. I'm not sure what I'd be buying if I got one of these, so pass.
 


I ended up with a 6700k. I am not overclocking, as I am using the H170 board, that I got from Onus. I am hoping for a Z170, later this year. Been eyeing the Asus Sabertooth Z170s.

Pros

Very efficient
Excellent voltage regulation
Good ripple suppression
Semi-fanless, Almost silent
Very competitively priced

Cons

Shuts off at full load (−1)
Some questionable quality capacitors (−1) in a semi-fanless product that advertises higher quality capacitors (−0.5)
Messy soldering (−0.5)

PIECE OF JUNK.
 🙁

 


So, the 6700k, not overclocked, is a max of 110w on some reviews, but our own TH torture test shows much less than that at stock clock 100% core usage. So we'll say it's 110w, just for the sake of argument. Throw in another 50w, which is probably far more than the rest of the system does or could ever use anyhow, in addition to the 326w from the GPU card at 100% usage, and that's 486w.

Close enough to the 60% for me. And actually, it's just about 65%. So maybe even an 850w unit would leave you directly in the 40-60% range at 60% being 510w. Either way, falling anywhere near that range with a high efficiency Platinum or Titanium unit, even Gold, is going to be very, very efficient even on a 24/7 machine.
 
What does the waveform of the voltage like after the bridge rectifier? If I'm correct, it is DC, but then the switching transistors turn it back into AC? Also, the switching transistors create a square waveform, not sine, correct?

Yes I did Google this stuff.

Is it a pulsating positive voltage that comes out of the rectification bridge? Like absolute value of an AC sine wave?
 

You're getting better :)

After a brige rectifier, it's Pulsed DC.

I'm not sure whether the switching transistors produce pulsed DC or actual AC (might vary between topology), but yes, it's generally square-ish. Filtering rounds it out a bit.

The reason it goes from AC to DC and back to AC is you can use a much higher frequency (100kHz+), which means the transformer can be way smaller and lighter.
 
Yeah according to Hardwaresecrets the switching transistors make a square voltage.
The input voltage is rectified before passing the switching transistors, and what they send to the transformer is square wave. So what we have on the transformer output is a square waveform, not a sine waveform.

How can we rely on anything there when the title says cooler master V series and the sub header down below says Corsair V series. I don't trust much of anything coming out of techpowerup anymore since they began inserting intrusive persistent ads and it just seems the article quality there has gone downhill as well.

^^Yep I've read it quite a few times myself, perfect alternative to the 850 G2.

@Darkbreeze: Techpowerup reviews are by the same guy who does the Tomshardware reviews.
 
Without voltage, ripple, and noise, all under various loads, people aren't going to take that seriously. Obviously though, it is a PSU-shaped object, unfit for purpose. I don't think I'd even use it for light bulbs.

 


You don't even need those values to see how bad it is, though. And it's still better than those reviews that literally plug the PSU into a machine and go, "yep, this thing works! Great power."

I should get a multimeter but am unsure how to create various loads on it without hooking it up to a PC and ruinng hardware when it blows.
