This is the cheapest Leadex 850-Watt PSU on the market. Even cheaper than the SF-branded model. I have a PCP&C Silencer Mk III 850W, which is identical in virtually every way to the EVGA Supernova 850 G2, except PCP&C uses a proprietary circular cable plug.
The problem is, the PCP&C cost $200, almost double the EVGA, for the same internals.

To the author, if you don't understand the primary reason for the existence of a jumper for the atx connector I would advise against speculating. Or perhaps spend a few minutes reading through the results of a google search before posting a review article on a topic. After all since you're writing a review on a notable hardware blog we presume you are an authority, such comments as those listed above make some of us question that presumption.
Why so snark? At last try some constructive criticism.
To the Author: a ATX power supply jumper is useful for example when you set up your water cooling loop and you need to bleed in first and to check if there are any leaks. Therefore you don't want the entire system to be powered on obviously.
Speaking as someone that has done plenty of time with Bitcoin and other cryptocurrencies -- and as the person that added that comment -- I can assure you that using it with BTC ASICs is indeed a plausible scenario, though perhaps becoming less so as everything moves to higher performance ASICs with built-in PSUs.
To the author of this comment: you do realise you sound like a complete and utter tool ? If you have something to add, add it, no need to be such a snarky git.
All very nice, but for a change, given the increasing popularity of Mini-ITX, how about a low-end PSU series test of 60-360w PSU's for non-gamers/light gamers/HTPC/office box/net box, etc, that comprise the vast majority of general usage scenario's? I mean 60-160w pico-PSU plus maybe the Seasonic G360 (lowest wattage Gold rated full ATX)?
Removing the discrete GFX card from my main i5-3570 rig, it maxes out at all of 90w (exc monitor) 4T Prime load at 4GHz and idle's at a lowly 24w. An i3-based HTPC / office box typically draws 24-70w. Add a 7790 XBOne equivalent card, and it still barely pulls 120w max when gaming. Yet you wouldn't believe how many tech sites continue to test such usage scenarios with 800-1500w PSU's with low-watt efficiencies that are way down at 50-70%, which results in completely useless figures for the typical uses such machines are built for...
I believe they already did one small-psu test over here, but I'm not able to find it now. google it around a bit.
And I agree such big PSUs are not the best option currently. Of course for high-end gaming/computing it does make sense, but with midrange getting better and better each generation, we will soon have a hard time buying such power-hungry computers.
I myself use an i5+gtx660 and run a lot of games. Most of the time I'm limited by v-sync, and not the hardware. I'm not a professional, just play for fun, so no reason to upgrade. My system is powered by a simple 350w unit from Akasa - I'm living on the edge here, but it works: no bluescreens nor shutdowns nor performance hit.
I'd like to see more small/mainstream PSU reviews too. The problem is that most hardware reviewed is whatever the OEMs are willing to provide; meaning there's a large bias towards halo devices over everything else.
Depends on wether or not people are interested in 120Hz gaming @ 1440p or even 60Hz @ 2160p. For that kind of stuff you need SLI/CF unless you - more or less drastically - reduce IQ.
True; most of our upcoming reviews will be of high output units. As mentioned, we are limited to what companies like to provide for testing and, for various reasons, every PR department likes to promote the best they have, even though it does not account for the majority of their revenue. This applies to virtually everything, from sewing needles to cars, not just PSUs. However, I have requested low output units from several manufacturers and some of them were positive, therefore we should be posting such reviews in the following months as well.
Nice photos of the box and what it looks like out of the box but wheres the test data and a photo with the lid off so we can peek inside to see the 'guts?' do they really use Nippon capacitors? is the fan bearing sleeved (think bushing) or ball bearing? the 850 G2 review did this, was this review done on Fri afternoon? C'mon man give us the meat and potatoes so we can make a choice not just a laydown of the components in HD.

Super Flower and Seasonic get into a PSU fight, who wins?jnkweaver - Friday, May 30, 2014 - link
It is about a tie. Superflower and Seasonic are both high quality manufacturers. They don't make or market budget supplies.Antronman - Friday, May 30, 2014 - link
Surprise surprise. A superflower-made PSU is "stellar".Well no shit.

Actually, it was more a pun on the "Supernova" being "Stellar". Hahaha....Antronman - Friday, May 30, 2014 - link

PCP&C Silencer Mk III 850W uses the Super Flower Golden King platform, so they are not the same internals.boberino - Friday, May 30, 2014 - link

An ATX P/S jumper is also useful if you want to power a storage enclosure.I use an 850W P/S in a Norco 4224 (4U rackmount case with 24 3.5" hot-swap bays) with an SAS expander in place of the motherboard.
