Coolmax 1200w vs others...

[Jungles39]

I was looking at a coolmax 1200w psu, now i've read the review for the coolmax 1350 version and it was recommended a very good psu, what i'm wondering is can it hold the load that it is rated for?

looking at the specs for both i don't see any difference at all in amperage or anything, except for the loads.

jonny claimed that the 1200watt was built by CWT

http://www.jonnyguru.com/modules.php?name=NDNews&file=print&ndns_id=139

So can this thing actually handle 1200 watt's of load aside from that it appears to have very low ripple and is definitely in the 80ish plus percentile.

Also comparing the 1200 watt to a thermaltake w0133ru 1200 watt, which would you believe is superior or are there pretty dead even?

1 more thing is it a DC/DC

I wouldn't bet the farm on it. The big Coolmax units were all Sirtec (now Sirfa) to my knowledge, and overrated.

I did?????

1. That's just a news blurb.

2. That was posted by Tazz, not me.

3. Tazz only posted what was reported by the Olin, who submitted the link to his review. In his review, he didn't open the unit up and the label doesn't have a UL number on it.

The unit could be a CWT, but I don't know if it is or not. The modular connectors look like it, but is that enough?

You reference a review from 2007. No, these are old designs.

If you are dead set on running 4 fermi cards and overclocking, your only real choice is the Silverstone 1500.

The extra $100 will be money well spent to avoid the hassle of wondering why your cards won't overclock and your system shuts down randomly when you are gaming.

If you want to save money and use one of your existing PSU, why are you dead set on 1200 watt and above?

Add the Corsair 950TX for like $120 to run 2 or even three of your cards and your existing PSU to run the rest.

I'd take 950 watts of good power over 1200 watts of questionable any day.

There's really no one here that is going to recommend buying 3 year old designs when they know the improvements that have been made in those years.

[jonnyGURU]

Here's a review with internal shots:

http://www.pcstats.com/articleview.cfm?articleid=2179&page=3

It's a Sirfa, as Wolf said. Not a CWT. And it certainly doesn't use DC to DC.

It was probably assumed to be a CWT because the modular connectors look very much like those on a CWT unit.

[Jungles39]

but i'm comparing reviews of the actual model, jonnys review on the 1350 was a recommend award and the link to the 1200 model also stated to be very good which is the 1350's little brother, plus its definitely 80+ plus?

I'm missing the logic here, how is this bad? just because something came out a long time ago don't make it horrid.

My main question is the load can it actually handle 1200watt

The person who wrote the review already gave you the answer

I wouldn't bet the farm on it. The big Coolmax units were all Sirtec (now Sirfa) to my knowledge, and overrated.

This is what he wrote in the review for the 1350W


I'm not convinced you want to try and pull 1350W from it - I don't think it's good for any more
The Bad:

*
might only be a 1200W Sirtec design. Overrating FTL.

Based on the 80plus report...the 1200 is BARELY 80plus...at 25C, so will not be at normal operating temperature.

First, they're completely different units in construction....they're NOT little and big brother.

Neither is CWT built, despite Tazz's saying it was in the link.

And if you'd closely read OKW's review, he said,

I'm not convinced you want to try and pull 1350W from it - I don't think it's good for any more than the 1200W Sirtec design it's based on.


So, OKW said it probably wouldn't put out any more than the 1200W he mentioned, and I wouldn't even try pulling that much from it, given its Sirtec pedigree.

And that review at Benchmark Reviews you seem obsessed with.....the testing done there is anything but comprehensive or even done well. No real load testing, only run with the most power hungry computer they had.

And a mildly OC'd C2D 6550 cpu and one mildly OC'd 8800GTS video card isn't anywhere near the load a more modern and power hungry system (i7 OC'd and something like a 470 in SLI) could draw.


Personally, if says Coolmax, it stays where it is.....and put on my ignore list.

[Smoothie]

Coolmax? I cringe at the sound of its name...

[Jungles39]

As for my secondary powersupply( since i will be using 2 ) i was thinking of getting the Corsair HX1000. This power supply will power 3 GTX 480's ONLY & overclocked to SHIT.

Does this psu have DC/DC like some suggested to get and what do you think would it be sufficient enough to be able to handle 3 gtx 480's and nothing else.

As for my primary power supply i'm going to be using a 1200-1500 watt still trying to figure out which model(price is an issue)

[Jungles39]

Also what do you guys think of the antec quattro 1200watt, jonnyguru didn't give such a good score but the efficiency and ripple suppression was very good.

I was thinking for my primary psu i would use the antec quattro, you think it can handle a core i7 overclocked to 4.6-4.7ghz + with 2 gtx 480's overclocked to shit?

EDIT: i was wondering one more thing whats the difference between the antec quattro 1200 and antec quattro 1200 oc model. I've seen youtube showing that the oc model can handle gtx 480 4 way sli.

Hello?

[mdk777]

Yes, I think a 1200 watt PSU will handle, what 800 watts?

However, I'm still not following.

Let's just assume for a minute that you are successful in running all five cards at some insane OC and gaming intensity such that you are pulling 1500 watt on the cards alone.

You do know that you will need to run an extension cord to an alternate outlet, one on a different fuse?

If your rig is pulling more than 1500 watt, you will be blowing the fuse on your standard outlet.

Seriously, it is very easy to save money and test as you go.

Buy the Siverstone 1500 and 3 cards. Buy a 20$ killawatt meter and see what you are drawing.

Test the three cards in sli, 3x sli, and sli with rendering.

Look at how many AMPS you are drawing. Buy a fourth card and repeat the testing.

I guarantee that you will never get to the fifth card and run out of amps on the 1500.

You will see insane reductions in improvement, and convince yourself that more than 4 cards is totally useless.

You will convince yourself that the money could be better spent on water cooling, or better fans, or ssd.

I guarantee that if you test as you go, two PSU and a fifth card will be your lowest priority.:D

Finally, if you insist on running 5 cards and two PSU, why are you looking at 2200 watt of combined power at 450-500$?

If you are going with 2 PSU, get 2 950 TX for $280.

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139013

1900 watts will be plenty but you will still need two circuits.:)

[Jungles39]

I'm aware of the circuitry issue, all i was asking was information in regards to the psu's solely.

[mdk777]

Yes, but the reason people ignore your posts is because you so absurdly over supply. They figure if you are own you own mission, then you really aren't interested in listening to any logic. Hence, they don't bother replying.:)

Nothing personal, just my observation.

[Jungles39]

Where is there no logic in what i stated?

I asked if a hx1000 would be able to handle 3 gtx 480's independently super clocked and as for the other question it was in regards to whether a antec quatttro 1200 can handle i7 super clocked and 2 gtx 480's super clocked

and the last question was the difference between antec 1200 and 1200 oc model?

I don't understand how there's no logic in my question, its like 1 + 1 there is an answer, but you have managed to hit the nail on the head on 1 thing. It seems i get ignored just for some personal reason, o well then, i believe the setup will be able to handle intensive overclocking and the hx1000 i read has a DC to DC converter so i guess that's what people we're recommending in regards for a independent psu.

fyi high end water cooling was on my list prior to coming here

[mdk777]

good luck.:)

PS Hibert's numbers on 4-way set up.

Just over 1500 watt at the wall with OC.

The Silverstone 1500 would have been good enough.

http://www.guru3d.com/article/geforce-gtx-4way-sli-review/8

[Jungles39]

i stated above price is an issue and the psu's i'm listing i can obtain for a good price then 1 silverstone 1500 which wont even handle the load i'm talking about.

[370forlife]

Wait you are talking about 5 GTX480's and price is suddenly an issue? Why not drop one of the 480's and just get a silverstone 1500. You're not scaling well when you get that many cards.

[Jungles39]

Yes that's exactly what i'm talking about, i'm obviously out of my mind, but i can imagine Thomas Edison was a bit out of his mind as well when he thought of inventing a spherical bulb that illuminates light from electricity.

That's exactly what i'm saying, ODD huh

I'm done with this place, from now i'll test things on my own, who cares if i burn money the learning experience will be daunting. peaces.

I'm sure the forums at Tom's Hardware will be much more accommodating.

You could also try the Sapphire forums, Gr33nGecko is a PSU deity. He practically glows.

[mdk777]

from the GURU 3D article:

Heck it's even ridiculous if you'd opt it. Quad SLI at this time is not even supported in games, just 3DMark Vantage has official support.

If four is not supported, I don't know what he is going to do with 5.

I also don't know what he keeps talking about psu he can obtain at a good price. He must be looking at used. Neither the corsair Hx1000 or the antec 1200 are inexpensive.

[Smirnoff]

Vaya con Dios! :D

[HOOfan_1]

I gave up on this topic long ago when the OP showed he was determined to ignore every piece of advice he was given.

Not sure why people like that even bother to start a thread asking for advice :wall:

[MrWicked1968]

Maybe Juggles can get Enermax to build a custom PSU just for him and his Monty Haul system like that fellow "Darkmatter" claimed was done for his uber-machine.

[Zero82z]

They say a fool and his money are easily parted. I think this thread is very good evidence of that.

[HOOfan_1]

There was a guy on Gamesradar who also claimed he has a PSU custom made.

I MADE a fool of him pretty fast though.

[MrWicked1968]

yep, that's the guy I'm referring to. I'm sad now that I deleted that thread from my favorites.

[SoulBrotha]

English proverbs FTW! I'd say "fool" is about right in describing the OP.

this one?

[MrWicked1968]

yep, that's the one.

I love how they vary between money being no object to suddenly being on a tight budget. Custom made Enermax PSU's, 5 $400 video cards, etc.

makes me recall the good old days of my level 600 elf mage with the ability to manipulate time and space. Monty Haul FTW!

cuq-1200b is 80plus certified. dont know why coolmax didnt categorized it as certified.
it's manufactured by SIRTEC also now known as SIRFA who manufactures and sells their own brand HIGHPOWER

[jonnyGURU]

We established that by post #5 a month and a half ago, but thanks.

[rollinshultz]

I have been using the coomaz 1200 for a year now and I used it even with two quadro fx 4600 cards and six gigs of ram, but now that I am using a geforce 580, I am having problems when running crysis. my quadros ran it in very high mode albeit at a low 12-15 fps. Mt 580 wnats to run at 60+ fps, but as soon as the game starts changing secenery (pc walking) it crashes. All posts seem to indicate it is a PSU issue and after reading these responses, I am inclined to agree.
The 580 need two plugs (a six and an eight), so it likely is not getting the right amount of power.

I will try the silverstone 1500.

do you really think that a single GTX580 needs more power than two quadro FX4600's?
