We have on our test bench today EVGA's flagship PSU with an enormous capacity and Titanium efficiency. We expect it to preform incredibly well because it uses Super Flower's high-end Leadex platform and comes with some formidable specs.

Been rocking a 1600T2 in both my and my roommates PCs.

Excellent PSUs.

Nice psu power cable c19 format It can handle up to 20 amps.. meanwhile the arleady knowed c13 just can handle only 10 amps..

the 240v version doesn't need as much current due to the higher input voltage. The US version isn't even really useful unless you're on a 20A breaker which will only be niche use cases as it is.

Edit: I also noticed my NZXT Hale90 have different effeciency curves for 120 and 240v, It would be nice to see a comparison for 120v input sources.

Great review as usual. I feel people really under appreciate how much tech goes into making all these measurements, very few other places review units to this level of comprehensiveness.

Only thing I'd like to see more is an easier way to compare different ups and downs of the units reviewed. I don't have too much trouble with it myself since I end up remembering strengths and weaknesses of each platform, but it is quite overwhelming for someone who is only just entering the market.

poor soldering
some caps rated for just 1000 hours
very loud fan (no heatsinks and also dual ball bearing)
bad inrush current
bad 3.3V transient responses
failed EMC
bad performance per dollar

highly recommended

Recommended for its intended usage scenario. For those needing a highly efficient PSU to drive power-hungry hardware relying predominantly on 12V supply, it's a fantastic purchase.
The recommendation should not be viewed separately from what the review will tell you about the PSU.

Oh and I think it's safe to assume that the cap life rating doesn't work the way you think it does.
In short and simple terms, if a cap is rated for 1000 hours, that means the manufacturer has tested it for at least that long without using any wear acceleration techniques.
What I mean is, the cap was actually working in a typical usage scenario environment, and not in increased temperatures/voltages/other forms of stress and then the lifetime multiplied by a factor to compensate.
This is why you will see some of the capacitor product lines get their endurance rating upgraded over time - the caps will have simply reached the next milestone (2k, 3k, 5k, ... hours) while still staying within the manufacturer's specification, up to a standard deviation.

Great review, Aris - keep it up! :)

the caps with 1000h lifetime are in a low stress area and this period is under worst case scenario, meaning 105C operating temperature and with the max voltage they can endure. Every 10C drop in their operating voltage doubles the lifetime and there is also a reduction when the operating voltage is lower than the max allowed. Lets say that they operate at 55C (a very high ambient) and without even taking into account their voltage, the lifetime goes up to 32,000h or 3.65 years of 24/7 operation. If we take into consideration now their operating voltage which under any case will be lower than 12.5V, then this lifetime can be easily increased to around 5 years of continuous operation.

This thing can be used as a car-starter. It should be noted that a PSU like this does exceed standard ATX size. It's 1.5x longer then a regular, 300W psu.

Great rev. :) +!

Well, I'm pretty sure that PSU's like these aren't going to be fitted in a tin-can sized cheap case.. :rolleyes:

Really? I guess you haven't seen any GTX 750 builds with a 1000W PSU stuffed into a cheap case?
Lucky you! ☺
A lot of people just look at the 'bigger-better-more' stats and the e-peen factor, and spend money in all the wrong ways.

Yeaaah then thats a problem you're gonna have to deal with. Can't really blame the PSU for stupid, especially when the specs are readily available.

Yeah, that's not really the problem.
But have you checked the rest of the specs?

175mA ripple current and 1.4 Ohms ESR. Sorry, but that's just bullshit...
I don't understand why they need those caps...
Decoupling drive connectors or something like that?


Besides:
Wanna bet that there are some Nippon Chemicon KZE or KZH series capacitors in this unit?

They are needed because the KY are not low impedance...
So you'll find the KZE in the +12V filtering part, where you may have to use a dentist's mirror to read the series on them.
Or just desolder them...

Solderquality is, I'd say, a 3.4 in (german) school grades...


Inrush current is on the high side but still inside the range of a standard B16 breaker. 3-5 times the nominal value is the 'short circuit' break point wich is something between 48 and 80Amps...

So it's still OK for 230VAC areas.

Well, if your breaker isn't fifty years old, of course (wich is more often the case than you may want to think)...
