As your defending them and nothing wrong with that as long as you have credible data to confirm that they are making such good power supplies. This is the first I've heard of them so it sounds like they do well oversea's. Please give any good reviews, tests of these power supplies and so forth. It would be good to know.
If you don't then please don't post anything more than I heard that they were good. Information on the internet is already in situation critical overload LOL..... so if you have links please post them for all to read. It would be great to know.

Hi, I'll try to put links from now on. I can only say I think the tests was done at either Hardocp (I'm not sure about the name, I had a reinstall and lost most of my bookmarks but they do good tests on power supplies and Tom's hardware did a bit of testing as well. Just go to those sights and look at their power supply sections for their past reviews if your still interested.
I was really impressed by their reviews. They use proper testing meters that show noise and loading which is very critical and isn't done by a few other sites that don't have the money or the will to invest in testing meters and O-scopes that are really needed when their testing power supplies.
Noise is always a important issue when voltage levels are getting so low that any potental noise that could make it too the cpu ( though getting through the motherboards regulators now days is next to impossible) but still any power supply that puts out a lot of noise is not one to buy for any reason because it's sloppy and gives more room to damage data or hardware. I saw a warning from AMD to not use memory over 1.5v with it's new cpu's because it can damage it and so just a .1v spike jump could potentally ruin a cpu is reason enough to watch for poorly made power supplies. I could not come close to knowing how it could make it through this way but better safe than sorry right?
I am sorry I can not be very specific on a lot of stuff unless I write it down. I lost that ability to retain this kind of data after my accident and can only go by general information for the most part. Very sorry about this. I just still like to help get people to think more about the topic the best I can. I'm making a lot of people mad at me over the whole AMD/Intel issues because of the poor testing being done on the new AMD cpus by the major sites that is very obvious but people are happy to gloss over what AMD is trying to do with this new design that is infuriating. It's all about a long view issue built into their cpus and future potental that won't show up for a few months so I'm getting into tons of heated posts about this.
But oh well, merry Xmas to everyone, I am going into hiding as usual this time of the year. And be very careful with new years too ok? Health is everything so don't get into a situation where you can ruin yours. I did and am very much like that House char. and take tons of pain pills for the last 20 years and it's horrible so stay safe!!!!!! Have fun but don't ruin your health ok folks???? I went from very smart to smart that I can't use anymore consistently.
 
So I am getting this --> COOLER MASTER Real Power Pro1000 RS-A00-EMBA . Is this enough for x2 6950, 6 HDD, 1 SSD, 5 Fans, i5 2500k (overclock). The OP says that I need to have 40 amps on the 12v rail, but the specified PSU only has 18 amps.

Please help.

it has 6x 18X rails for 12V.

i would not recommend that PSU.


the positive reviews on newegg give it away, none of the people reviewing it got past the "OMG 1000 WATTS AND LOTS OF CABLES" stage. the few who list system specs, are listing old, non power hungry hardware.

the few who do... well

Pros: Coolermaster RMA department are good. This power supply is ok for mid-range systems. Looks cool and stays cool. Quiet

Cons: After 8 monthes the power supply would randomly shut down. Trying to restart your computer afterward could only be accomplished by unplugging the power cable, waiting for the LED's to go out then plugging the power cable back in.
i RMA'd the first one thingking i just got a lemon one. 8 months later the same thing with the new one...
Click to expand...

Pros: Well built looking PSU...shiny, nice fan, moves a lot of air

Cons: You would think a close to $400 PSU would be a well built one.....but...
Can not handle the system =\
Computer randomly shuts down and restarts when under-load. I tested EVERYTHING on my build....GPUs, RAM, tempts, etc etc. All came down to this power supply. No BSOD, nothing..just a total shut-down. Gets EXTREMELY irritating. I am not even running a tri-SLI nor a full ram capability....no extra fans...

Other Thoughts: running: i7 920
Asus p6t6
6 gigs ddr3 ram
2x Asus matrix GTX285
3HDDs (1t, 750g, 500g)
Click to expand...

Pros: 1000WATTS, worked good for the first couple of months

Cons: causes random shutdowns and restarting of your computer, also causes your sytem to get the blue screen of death. I never thought it could have been the PSU causeing this, but after doing some research and testing my components, I am almost positive its this PSU. I'm gonna try an RMA and see if its just a bad PSU.

Pros: Lots of connecters, lots of power

Cons: After the first couple of months the PSU started causeing the computer to randomly restart and get the blue screen of death. I never thought it would be the PSU, but after extensive testing (and 9 months of experimenting with different operating systems......linux anyone?) I am positive it is the PSU causing this

the PSU is a lemon. dont go near it.
 
What about Cooler Master Extreme power plus 700w?

Well it has a "single +12V rail (up to 52A)" which is better than the one I have. One 12v rail is better than multiple.

a single 52A rail sounds quite good, but in my experience coolermaster PSU's have all been bottom of the barrel junk. I love their cases and other hardware, but their PSU's tend to be pretty crappy.



I'm sure they do have some good models in their lineup, but i'm not aware of them. google is your friend there.

thanks. i blindly follow jonnyguru's advice with this stuff, he really is a PSU expert.

Hey Mussels,
So I was looking at a Corsair HX1000w and it has multiple 12v rails, so why is it more reliable and have more positive reviews than the 1000w CoolerMaster Real Power?

as i said in PM, because coolermaster PSU's tend to suck, while corsair dont.

Not really. It still depends on...everything else.

i believe that less rails is better - but a shit single rail PSU is still shit, vs a quality multi rail.


the main problem with multi rail PSU's is when the rails dont have enough power - EG, no matter how many 18A rails you have, you're still capped at a low amount.

now two (or more) 35A rails, you'd be hard pressed to over load.
 
Can someone tell me why isn't chieftec mentioned here either as bad or good brand? It's funny how thoughts on this company are mixed... Some say it's bad some say it's good. I really have no idea which PSU to buy(I mean i have no idea which brand is good for quality products for money etc...). Also please bare in mind that i don't want to invest 150-200 euros into a PSU... i'm investing about 70-100 euros :)
 
I'm just wondering looking at the front page, what about the newer 80+ Platinum Kingwin PSUs? Just noticing that Kingwin is listed in the "companies to stay away from" with the superflower internals.
Just wondering, I'm probably going with an OCZ or Seasonic myself.

Because the first post has never been updated since 2007.
 
if someone comes up with an updated first page and its gets approval on here, i'll stick it in. just copy paste the entire first page, update it, and put it behind a spoiler tag.

I'll try working on that then. :p
 
Mussels said:
with four 18A rails i'd stay away. its too easy to overload such a weak rail on modern systems.

then which one would u suggest from chieftec that is around 700w?

anything with less rails, and higher amperage per rail.

afaik chieftec isnt sold in my country, so you'll have to research this one.
 
Can you explain me a bit what's with multi rails?? can't you like combine those 2 rails to get more A?
