EVGA SuperNOVA 850 P2 Power Supply Review

[Guest]

EVGA recently enriched its P2 line with three new members, featuring 650W, 750W and 850W capacities. All three, like the other P2 models, are made by Super Flower and feature Platinum efficiency. Today we're testing the 850 P2.

Why can't US use 220v, man so much more efficient.

Tradition... There is nothing (I believe) stopping you from running a 220v circuit. I know we have one 20amp NEMA circuit in this house specificity for the computer room. Its not common to see those in house holds either.

Tier-1 but on the low end of Tier-1 due to its hold up time.

Scores a 9.7 on Jonnyguru, but is low end of tier 1 got it.


I like Tom's in general, been coming here since Tom was actually doing reviews, but I'll take JonnyGuru's(or Oklahoma Wolf) word that this is an awesome PSU, it scored 10 of 10's in all but Value, where a couple of similar quality PSU were a tad cheaper.

I've got the G2 model(thanks to their review of it) and couldn't be happier with it. Well other than they now have Platinum and Titanium versions and would prefer one of those. But 80+ Gold is still good enough for me.

Well, i think that you don't pay that much attention to Jonnyguru.com, as much as you claim.

The same reason so many regions have different plug types. They all designed these things before anyone had the idea to standardize these things across regions, and by now it's an incredible amount of work to have to redesign the infrastructure of entire countries.

Why can't US use 220v, man so much more efficient.

"Technology, current at the time of US electrification, locked the US into 110, then 120 volt outlets. Europe's electrification came later, and proceeded in response to advanced technology. The US was too deep into the 110/120 volt infrastructure to upgrade."
Gotta hand it to the Americans for inventing the concept of the grid and power distribution to the masses, they did it first, and Edison's equipment at the time ran best on 110v so it was the obvious choice. Currently it's at 120v, this was changed in the 50s. Don't forget houses are supplied with 240v, this is what runs our hot water heaters, ovens and air conditioners. Just the old way is still too set in stone to be changed, not to mention 120v is safer for human exposure (a shock from a 120v outlet is much less dangerous than that of a 240v outlet, having experienced the 120v shock I can't imagine how painful a 240v would be)

Yep...I was popped by a 220v 3-prong washing machine plug wire that arced some two decades ago (when it was still known as a 220v power connection) and it knocked me on my butt. It makes getting hit by 120v (used to be 110v), which I've also experienced more recently, seem like carpet static electricity.

This is the summary for my EVGA 850 G2 (Tier 2 according to his list, a WIP according to the post)

Performance
10
Functionality
10
Value
10
Build Quality
9.5
Total Score
9.9

Summary

Buy one. Do I really need to say anything else at this point? Once again, EVGA has something awesome here the competition can't seem to touch price wise. Performance? There are better units, yes. Not very many, but they exist. The real story here is how EVGA keeps managing to offer this kind of performance and still be more affordable than nearly everything else out there, and they have pretty much found perhaps the only OEM on Earth capable of doing it for them. It's got to be real nice being EVGA right now.

The Good:

• 
  outstanding ripple suppression
  excellent voltage regulation
  fully modular
  semi-fanless mode
  nice blacked out cabling
  

The Bad:

• 
  nothing at all

The Mediocre:
reviewing awesome units is getting dull... where's that gutless wonder in my pile? Second in line? Well, at least I'm guaranteed something interesting in all the wrong ways in a couple weeks...

It scores a 9.9 of 10, and is somehow a Tier 2 according to that list. I have no clue as to what he is doing with his list on the forums. I cannot explain HOW a unit that scores 9.9 of 10 is anything less than Tier 1. There are some Corsair units that scored perfect 10's that are also listed as Tier 2 on it as well.

If it's scoring that close to 10, or an actual 10 (his highest score), it's a Tier 1 to me. And I'd never second guess buying one regardless of brand.

you guys cry like a baby. i use 227v on the computer no ground. with a multimeter can see about 45v on chassis its nice to touch it. i use a ps3 power supply to drive a 400w car amplifier and the psu barely get warm, no fan only passive cooler. 127v as no good use anymore on non days.

LOL. Come on over to my house and I'll show you the difference in 240v and 120v when you touch them. But I will need a liability waiver signed.

That's because the reviews that you refer to, are Jeremy's (Oklahoma Wolf), while the Tier list is Jonny's.
So as you can see there is some difference of opinions.

 

[Aris_Mp]

both 115V and 230V can kill! Also it doesn't have to do only with the voltage but with the current and with 115V the amount of current is increased!

Methinks one has to take that list with a grain of salt, most especially where Evga P2 and above are concerned. A lot of ppl on the thread were a tad confused at how some units were placed in T1 and others in T2. Halfway through the thread the author of the list says he'll likely merge Tiers 1 & 2 at some point in the future.

However... If I thought Superflower's leadex platform was somehow inferior to Seasonic's equivalent, I would've reconsidered when i got the 1kw Evga P2 for my own sys. The price difference isn't significant, especially if one takes sales into account. Even the usually $60+ more expensive Antec HCP 1kw Platinum was competitively priced for a bit on Newegg around the holidays iirc. I can't imagine seeing the titanium 1kw model [Evga T2] placed in Tier 2, either. Even according to some of the site's own reviews, some of the tier placings simply don't make much sense.

Others, that showed the most promise, namely Andyson's titanium offerrings, haven't been mentioned in said list yet. This may be due to Andyson still not having inked out a contract with a brand name for N.A./E.U. yet (any clarification would be appreciated re Andyson btw).

1) I was also one of the persons who were confused, but because someone gets confused doesn't mean that the list is wrong!!
2)What do you mean by that? That according to your opinion, your EVGA P2 belongs to Tier1? I also own an EVGA G2 750 & 850. Surely i would like to see them as a Tier1 units . So what? Do you or i, have higher expertise than Jonny on the PSU field? !!!!
3) Jeremy & Jonny are both reviewers and used to work for the same site, but that doesn't make them identical twins!!, who are thinking exactly the same!! Apparently, according to his list, Jonny thinks as a Tier1 only OEMS like Delta, Seasonic and Flextronics, and the other OEMS are one step down. Lots of people probably will get confused, but the fact is that very few people have Jonny's expertise in the PSU field.

"1) I was also one of the persons who were confused, but because someone gets confused doesn't mean that the list is wrong!!"

True. However, does it necessarily mean the list is by any means complete yet, and thus definitely "right"? To the point some odd and conflicting placements between tiers 1 and 2, have begun to be explained with any degree of satisfaction? If some placements remain as they are presently, I'd wish to know why. Especially given the discrepancies between some units' ultimate scoring and their list placement, (including the site's own reviews, regardless of author), noticed by some of the site's faithful readers.



"2)What do you mean by that? That according to your opinion, your EVGA P2 belongs to Tier1? I also own an EVGA G2 750 & 850. Surely i would like to see them as a Tier1 units . So what? Do you or i, have higher expertise than Jonny on the PSU field? !!!!"

Speaking for myself, I'd say no. Allow me to put it another way: If, after the considerable research I did, taking the reviews from JohnnyGuru and other sites into consideration, I thought Seasonic's 1kw platinum equivalent (or the others for that matter) held a considerable, tangible, qualitative advantage over the Evga 1kw P2, I would've gotten it or something else over the Evga P2. And just fwiw, I'm not attached as a fan to this or any other particular company. I chose a Nitro r9 390 for a gpu, where most would've surely chosen an nvidia instead. Why? Well, aside from the fact if we find ourselves subject to a total intel/nvidia monopoly in the near future, we'll have no one but ourselves to blame, it's actually an excellent card for the money, a great wqhd card as it turns out, with overall excellent build quality. Sry to get off track, just wanted to make that point.

Anyhow... The PSU list is a work in progress, which is prone to some changes and editing. According to Jonny's own post on that site's forum, on p5 of that thread he states: "Yeah, I plan to consolidate a bit. Like merge 1 and 2, for example."



"3) Jeremy & Jonny are both reviewers and used to work for the same site, but that doesn't make them identical twins!!, who are thinking exactly the same!!

I agree, I'm curious to see what the list looks like when done.
