EVGA or Corsair 1200w PSU

[m_tieu]

I currently have a cheap 850w PSU powering a 4770k and 2 gtx 780ti classified cards in sli. I'm looking at upgrading to either a EVGA P2 1200w or the Corsair ax1200i. Which one do you guys think is a better buy and why? Any help is appreciated. Thanks.

I have to say EVGA. I have that exact PSU.

It got a 10/10 on JonnyGuru.

And it has a 10 year warranty.

10/10/10.

Winning.

The EVGA Supernova 1200 P2 is $275 CAD, while the Corsair AX1200i is around $370 CAD. They both are excellent PSU, but I would go for the EVGA due to pricing.

 

What's wrong with your current 850w btw? And why are you looking to spend so much on a new PSU?

Corsair, well because... Corsair but may I ask, WHY 1200W??

Either one is a great choice.  I voted for corsair because that's the brand I've had the most luck with.

The actual better one of those two in terms of general reliability and quality is the EVGA.

 

I must ask, unless you're adding another GPU soon, why so 1200W bby?

I was thinking the same thing about pricing. But if the corsair unit is that much better that it warranted the price increase I would still buy it. The 850w isn't cutting it. My system crashes at full load when using both cards in sli. When I only use one card the problem stops and when I borrowed my friend's 1000w psu, there was also no issue. I also want something with more efficiency. My current unit is only silver rated, platinum seems better at higher loads over long periods of time.

EVGA, it's a better PSU structurally and higher quality components used. Pair that with the best customer service in the industry and a 10 year warranty makes EVGA a no-brainer.

I am not currently planning on adding another card since my board only supports 2 way sli, but I want to leave some headroom in case I decide to upgrade to something more power hungry in the future like dual gpu cards for quad sli or quadfire in the future.

Alrighty. Little excessive but it's your money.

It could be an issue with the Cooler Master Silent M2 850w. It is a group-regulated PSU that exhibit high ripples on the 12v at high loads, IIRC. Your crashes may be due to instability issue and/or the PSU going bad. But if you insist to invest in a higher wattage unit...

 

The AX1200i is manufactured by a server-grade company - Flextronics, and as such, the overall build quality of the unit is top-notched. The main issue I have with it is the fan choice, in which they used a mid-range 2BB fan from Yateloon instead of the better Sanyo Denki found in the AX. Performance-wise, it is better than the Supernova P2 electrically, but to be honest, these units are so well regulated and so well suppressed, it reach the point of bragging rights.

 

Other than that, what you are spending your extra money on is functionality. Specifically, Corsair Link. It allows you to monitor the fan speed, power draw from the wall/components/12v/etc. it allow to adjust the fan speed, switch between single rail and multi-rail mode (multi-rail by default if you don't used Link), adjust the OCP of each 12v if in multi-rail, and I think that's it.

 

If they are about in the same price, I would go for the Corsair, but for $100 more? Nah. If I wanted to spend more on something, I would go for an Antec High Current Pro 1300w Platinum (Delta Electronics build PSU - another server grade company), but that's still around $30 more and doesn't have semi-passive mode.

 

Nonetheless, they are all excellent power supplies, and it just a matter of how much money you want to blow for certain things.

Going on what a few others said, go with the EVGA as it's made by Super Flower, the absolute best OEM for power supplies. For the people saying buy Corsair because it's Corsair, well that's like saying buy Apple because it's Apple.

Super Flower does indeed make great PSUs, as shown with the Leadex, Golden Green, and Golden King lineup; however, saying that they are the "absolute best" OEM for PSUs is over-glorifying them.

Id take the EVGA any day over the Corsair. There is no need for the digital monitoring. there are also known compatibility issues with the 1200i. I believe the EVGA got a better review from Jonny Guru too and exceeds Platinum specs if I recall.

[TheProfosist]

@quan289 ill back the Antec HCP Platinum PSU's as well. I am using the original 1000watt myself. Antec's highest PSU line is the like Dominator RAM of PSU's and is probably one of the few redeeming things they have still. I wondering if they will even come out with a titanium rated PSU though with the switch for focusing on budget things. Which BTW was a bad call in my opinion.

[m_tieu]

Thanks for all the help so far, I'm leaning towards the EVGA unit for now. Most platinum rated 850-1200w power supplies are priced around $200-400 in my area. So if a 1200w unit is within $30-40 more than a 860w or 1000w unit, I'll buy it instead. An Antec HCP 1300w costs the same as the EVGA P2 1200w since I can pick it up locally, is that a better buy?

I would say its a better buy personally.

[Prolly_dyin]

Evga is honestly making some killer power supplies right now. A few issues with their bronze line but even that is typically just loud or dying fans. I see very few of their gold, platinum, or titanium rated psus having issues.

Corsair. i Had an evga 500w spit sparks out of the fan shroud and my local fire department was there and everything

Sounds unlucky though im surprised you had to call the fire department. Also dont judge a whole brand on a lowe end 500watt PSU. I wouldnt be suprised if it was one of the ones from before they switched to using letters in the names.

Do i need to know how in the hell you created a fire out of a fan big enough to get your local fire department to you???

That is totally irrelevant. The OEM on the 500B is not the same as the high end models.
