EVGA SuperNOVA 850 P2 Power Supply Review

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.
Look here, at Jonny's tier list, and notice what tier is the EVGA's P2 line :

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

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 cablingThe 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.
