Which is better? Seasonic M12II 850w or the 660w Platinum series?

[netxzero64]

Hi everybody.

Just a basic question as indicated on the title, which is a better PSU? Would it be the M12II 850w or the platinum series 660w of Seasonic?

Let's say I am planning to get a GTX 650Ti Boost for SLI. Price difference as the Platinum is much expensive is $15 to $20.

Any comments and insights would be appreciated. Thanks!

go here and check your requirements first.

Of course the Platinum series is "better" 90% vs 82%, but the 850W has more sheer power and plenty of GPU power plugs and it's a single rail

Normally I recommend 80+ certified PSU in the 650W, Brand name, so either one fits this.

the 660W looks nicer. How about a 760W Platinum and then you have both worlds?

I vote for the 660W

 

[netxzero64]

I see. I can't go beyond my budget as the 760w platinum is way expensive here in our country.

so 1 vote for the 660w platinum then.

Any other votes or suggestions out there?

i'd go with the Seasonic Platinum. A powers supply is something you buy once every 5-7 years, so choose wisely.

Seasonic is probably the best all around Power supply company at this present moment, its tough to mess up going with them. As nice as 92% is.... 80% is plenty for most of us. Look at your future PC purchases and decide whether the higher efficiency or higher wattage makes more sense. Do you plan to Crossfire/SLI with beefier cards? etc...

Its a tough call but I would lean towards the M12II 850w. Its 80% is fine for most SLI/Crossfire users and offers more cushion and room for growth.

The M12II 850w also got very decent feedback on newegg.

Both are rather expensive. For dual high end GPUs you should be looking at a Bronze or Gold 750W unit, and you can probably find a decent one from a different brand for less $.

Where are you buying from?

Go with the 660w platinum. Uses the new KM3 platform.... mmm PSU perfection.

Do you intend to run SLI with higher end video cards? Because the GTX 650 Ti Boost SLI configuration is not particularly power hungry relative to those higher-end video card SLIs.

I say get the M12II 750 instead.

Keep an ear out if you go with the Seasonic. The one I returned had coil whine.

That's not my experience. Even Seasonics usually die on me after around half that time. But a good power supply at least doesn't fry your components when it goes, and the better ones may last that bit longer.

i5 /w 650's?

lol... how about corsair PSU's?
CX600?

seasonic's cost too much IMO... they are great PSU's.. but cost too much for what available now.

 

[netxzero64]

Thanks for your insights gentlemen.

I don't plan on going SLI/xfire on beefier cards, just the 650Ti or the 750Ti if any of that is gonna come out of the spotlight. If I would purchase something with more kick, I'd buy a single GPU from x60 or higher in the series.

So what would be the best for the 650TI boost SLI? 660w platinum or the 850w M12II bronze?

yeah, even old i7 920's are not bottlenecked to Titan's.

 

[netxzero64]

That's fine with me. I had a palit GTX 260 back then with coil whine and i dont mind it. My rig actually can be heard from the first floor up to the 2nd floor of the house because the fans are under max RPM. I am used to the acoustics of my rig hehehe. Noise is not an issue for me.

 

[lehtv]

Yes they are. i7-920 is a bottleneck to even a 560 Ti in some scenarios, and it was enough of a bottleneck to a 7950 that I saw substantial improvements by upgrading to an i7-3770K. Titan is 30-60% faster...

Well I saw a review few days back and I see that an i7 920 can still utilize the titan provided it is running at 3.5ghz or higher.

I am searching for the link as the review was pretty good bringing out old rigs in action.

The GTX 650 Ti Boost has a TDP of 134 watts. TDP, while not being the actual max wattage a card can pull, is nevertheless an ok approximation for maximum GPU power consumption. I have a hard time believing your setup will even pull over 400 watts at the PSU output/450 at the wall. You only need a 600-650 watt unit. Even 500 watts should be ok.

However, the best deal for a higher-end PSU is the M12II 750 watt I mentioned earlier. In addition to its $20 rebate, it has a promotion going on that saves you another $20, making the final price, if all goes well, only $60 at Newegg.

Providing sufficient wattage does not require superior efficiency or protection circuits or whatever else; those things confer other separate benefits and are not correlated with wattage.

I understand but I will not be ordering through newegg as I don't have a visa credit/debit card and they have mentioned to me that I will be paying for the shipping fee as I am not in the US/Europe/Canada region. With that in mind, I will be buying the items locally here in our country.

Depending on where you live electricity can be really expensive so I would go with the platinum unit. I have been using Seasonic built PSUs for years and the Corsair AX850 I have in my main rig survived a large power surge in our house that took out the the PSUs of my two neighbours upstairs including a motherboard.

I have the aforementioned Corsair AX850 which has been running in two systems for well over three years now and two Corsair AX860 PSUs. I have not experienced any coil whine from them whatsoever. All of them are made by Seasonic. The new Seasonic KM3 platform is an absolute winner.

 

[netxzero64]

so your vote goes for the 660w platinum then?

 

[Nec_V20]

so your vote goes for the 660w platinum then?

Most certainly. The Seasonic KM3 platform made a great thing even better.

And for the rest of you reading this, only call me a fan-boy if you are talking about Noctua

Sure it can use it, but not to its full potential. Framerates will be higher with a modern CPU in all but the most GPU dependent situations and games.

 

[aigomorla]

if its cheaper then the CX650 in your country...

if were limited to just the psu's you listed, then id get whatever is cheaper... dont always go for the higher number.
The higher number typically also means lower efficiency at lower wattage, which idle does.

Hence why people run picopsu's for itx systems because they are more efficient then regular psu's at the lower wattage range.

I see. How about the M12II 750w bronze? Would that be fine also?

 

[aigomorla]

if thats cheaper then yes..

both are by seasonic.. both have quality.

it should be now about which is cheaper since ur on a constrained budget.
