Power Supply suggestion for a custom built system

Hey everyone, Im in the middle of finding parts for a home built system, I have most of the parts except the power supply. Ive looked through many different kinds but I cant make up my mind, so I thought I would ask the community for their ideas. So far these are the important specs

Asus Ramage II Extreme motherboard -
http://usa.asus.com/product.aspx?P_ID=W7i5W4Pw4fH22Mih&... (Product webpage)


A CoolerMaster HAF 932 Full Tower Case - http://www.coolermaster-usa.com/product.php?product_id=...

A Intel i7 950 - http://www.tigerdirect.com/applications/SearchTools/ite...

6GB Corsair XSM3 1600mhz tri channel DDR3

Also, the graphics cards i am considering are either Nvidia GTX 285 Or ATI Radeon 5870

1. I first want to either dual SLI or crossfire with the possibility of a third card later
2. I plan to have water cooling in there for the processor, chipset, and the graphics cards
3. Also I might overclock later
4. Finally, the type of power supply i would like is 1000+w psu which is modular and enough connectors and such for triple SLI/Crossfire at a later Date, I would also like to find a good reliable company so I know my psu wont burn out for a very long time

I was looking at this one (Ultra X4 1050w) but i saw some issues where it couldnt keep its 80+ Silver promise so I was looking at other options

If you need other information, ill be happy to provide it.

If anyone could find me a psu that matches all of the above, you have my eternal thanks!

Shovenose has actually made some good reccomendations.
If you decide to go for the Antec, shop around, it can be found for around $70 less than the Egg's price.

You would use it so that your peers on the forum don't think of you as a spammer for posting twice in a row in the same thread within 19 seconds.

First off, I built a Rampage II Extreme (R2E) box for my son a few weeks back and to my mind it was worth every penny, but with the R3E about to be released, I'd sit back a bit.

The HAF 932 is a fantastic case. Main reason I won't buy it is that it doesn't fit the Antec CP-850. The Antec 1200 / CP-850 combo is just too incredible a buy

Antec 1200 / CP-850 = $275
CM HAF 932 / Corsair HX-850 = $310

The Antec 1200 and HAF 932 are well matched....1200 has air filters but HAF has 3 pin fan connectors not molex so a gotta buy adapters if you wanna connect to MoBo headers. But the CP-850 is an incredibly quiet and outstanding electrical performer and it won't fit in the HAF. Frankly, I don't see a need for a 1000 watt PSU given the reduced power req'ts of current GFX cards.

Performance (40% of the final score) - okay. Let's figure this out here. On second thought, what's to figure out? We have an Antec 850W that performs better than a Signature that appears to cost less than a Signature. We have a unit that was promised to do 80 Plus standard, but ended up doing Bronze. No, the unit didn't quite match the Signature in terms of voltage stability, but it came real close. And to be honest, the differences in voltage readings were so small you could put them down to connector resistance. And since the ripple and noise suppression more than made up for the slightly less stable voltages... 10.

If the CPX form factor catches on, the CP-850 will be flat out untouchable. It is completely unmatched by any ATX unit on the market I can think of. You'd have to spend twice as much as this thing costs to find the next best thing, performance wise. I'd like to see some better capacitors in there, but you just can't fault the CP-850's performance here. I don't know how Antec managed something this awesome for such a low price, but they must really want the CPX form factor taking off if this is the performance we're getting.

The Antec CP-850 is a superlative power supply by almost any standard. Its electrical performance is up at the level of its more expensive brethren, the Signature 650 and 850, and Seasonic's flagship, the M12D-850: Voltage regulation is extremely tight for all the lines at all loads, and the ripple noise is amazingly low.

The noise performance is excellent, with the <400W performance matching or bettering virtually every PSU tested thus far. Above 500W load in our heat box, the noise level goes over 40 dBA@1m, or about the norm for PSUs rated this high. It has the virtue keeping itself extremely cool, however, cooler than any other PSU we've tested at such high loads.....Our atypical spot check with a room ambient thermal test showed the CP-850 would reach only 24 dBA@1m at 700W load in a 27°C working environment. This is ridiculously quiet for such high power output.

For the quiet-seeking computer gaming enthusiast, the CP-850 (along with any of the three compatible cases) is something of a godsend. Fantastically stable power, super low noise at any power load, long expected reliability due to excellent cooling, modular cabling, and all at a price that's no higher than many high end 6~700W models.


If you decide you need bigger, look at the ones with 10.0 performance ratings on jonnyguru.com

The Corsair is overpriced and not up to the performance of the competition. Muskin DDR1600 w/ 6-7-6-18 timings is the way to go on the R2E or R3E.

You won;t find the 285 on THG's January GFX card roundup. I perty much agree with all the choices except for the 5770

http://www.tomshardware.com/reviews/best-graphics-card,...

I don't really see a use for triple SLI / Xfire given the performance of today's cards. You don't mention resolution but twin 5870's or a single 5970 will tackle anything on a 30" monitor easily. Throw in a GT 220 (no power connector req'd) if you wanna do the driver hack here in case you get the urge to do PhysX

The "water cooling" and "might overclock later" seem mutually exclusive. A decent air cooler like the Megahalems will take your 2.66 Ghz 920 to 4.4 Ghz with temps at just over 70 degrees. Don't really see a need for water cooling for CPU or GFX in an HAF or 1200 w/ a decent HS.

My son is running the R2E in a 1200 w/ SG-850 and twin GPU's w/ CPU at 3.7 GHz for everyday use with CPU temps in low to mid 50's ....at 4.2 GHz profile for gaming, he just hits 70s

Interesting I really thank you for your reply, Do you know when the rampage 3 will come out or like some specs for it, will that 850 still stand up if i crossfire 5870s, also, and now I think the only things I would watercool are the chipset and processor bc they are the big things to worry about, but i am quite happy with the HAF932 saw amazing reviews on TIger, and I guess i will stay at double SLI, Finally, would the HAF 932 keep two 285's with stock fans cool enough so they wouldnt crash/overheat?
