auggybendoggy May 10, 2006 Share auggybendoggy Member May 10, 2006 Guys what does it mean 2x4 and 2x2 on dual rail power supplies and how do you know if the power supply has one or the other? Aug Link to comment Share on other sites More sharing options...
Guest zerodamage May 10, 2006 Share Guest zerodamage Guests May 10, 2006 Give us an example, link to the power supplies please. I honestly do not know what that could be (though it is realy late and I am seeing things as I am so tired). Link to comment Share on other sites More sharing options...

SiX May 10, 2006 Share SiX Member May 10, 2006 The best power supply on the market. Triple 12v rails. http://www.newegg.com/Product/Product.asp?...N82E16817703003 This guy Dual 12v rails. http://www.newegg.com/Product/Product.asp?...N82E16817151025 Link to comment Share on other sites More sharing options...
Laz.e.rus May 10, 2006 Share Laz.e.rus Member May 10, 2006 OCZ has a long standing rep for good power, especially with the DFI gurus. Check out some of the latest: http://www.monarchcomputer.com/Merchant2/m...ory_Code=ps-ocz Link to comment Share on other sites More sharing options...
auggybendoggy May 11, 2006 Author Share auggybendoggy Member May 11, 2006 this is what ive learned... intel EE dual cores need 2x4 in order to run properly. This means a dual rail power supply. a 2x2 will not do it. I read the mb manual and sure enough it's correct the website explains a little about it. I don't know what "dual rail technology" is nor do I know how to know if a ps is dual rail or not. Aug Link to comment Share on other sites More sharing options...
Laz.e.rus May 11, 2006 Share Laz.e.rus Member May 11, 2006 I "believe" what that is referring to is the 8 pin MB connector coming into play now. I know the DFI Expert board requires it ( vs. the standard 4-pin). IE: 2x2= 4 pin. 2x4 = 8pin Example: heres a descrip of one of those OCZ's: * 150 x 140 x 86mm * ATX12V v2.2 and EPS12V * OCZ ConnectAll™ universal connectors: o 1 x 20+4Pin ATX o 1 x 4-pin/8-pin CPU (supports double CPUs/supplies stable voltage) <-- **This is what I mean** o 2 x PCI-E o 6 x 4-pin peripheral o 2 x 4-pin floppy o 6 x S-ATA * High efficiency o 80% @ 115V (Typical load) o 83% @ 230V (Typical load) o Overvoltage/Overcurrent/Short-Circuit protection o Active PFC o MTBF:100,000 hours o 100~240Vac 10-5A 50/60Hz o +3.3V(36A), +5V(30A), +12V1(15A), +12V2(15A), +12V3(15A), +12V4(15A) Link to comment Share on other sites More sharing options...
SiX May 11, 2006 Share SiX Member May 11, 2006 ok makes sense. then thats the difference. pfft p4s consume way to much juice, what a joke pfft. lalala... no i see what your saying. just look for that then. correct me if im wrong but 8pin connectors mean the power supply is eps compliant? ive seen that with atx and with out atx next to it Link to comment Share on other sites More sharing options...
Cobalt May 11, 2006 Share Cobalt Member May 11, 2006 Intel processors always consume more power. This was true even with the first P4s when AMD was with Socket 462. Intel boards needed the "P4 12v 4pin" power connector and AMDs didn't. Now it is moving to an 8 pin power connector instead of the 4. Link to comment Share on other sites More sharing options...

Tek-Almighty May 12, 2006 Share Tek-Almighty Member May 12, 2006 PC power and cooling does make great PSU, but it will cost you.. I've used ANTEC as well as others for several years, but my new favourite is the Silverstone 600W modular for SLI systems... It has 78% efficiency, and it is rated to operate at that up til 50 deg celsius...that is pretty good. The other thing to consider is to make sure your PCI-ex power connectors are on separate rails...otherwise you risk failure. The silverstone has 4x 12v rails.

Cobalt May 12, 2006 Share Cobalt Member May 12, 2006 Silverstone and Antec both max good power supplies. Enermax also has some pretty good psus. PC Power & Cooling is hands down the best but like Tek said you do pay for it. The Turbo-Cool 510 SLI starts at like $215 without ship. Link to comment Share on other sites More sharing options...
auggybendoggy May 13, 2006 Author Share auggybendoggy Member May 13, 2006 ok guys how do you find out if sli cables are on diff rails? just word of mouth? Aug Link to comment Share on other sites More sharing options...
Cobalt May 13, 2006 Share Cobalt Member May 13, 2006 Word of mouth is definitely one way but if a power supply has seperate rails it is definitely something they will want on the box/booklet/psu itself. I'm currently building a machine with a Silverstone ST60F and this particular psu has quad +12v rails and it says it all over the psu itself and in the booklet. With a lot of the higher end manufacturers it is expected for them to have seperate rails and they will prominently display it on the packaging. If you can't find it that way try their website and search by model number. Link to comment Share on other sites More sharing options...

What I am saying about making sure your pci-x cards are on sep. rails, is to make sure you don't use an adapter to power both cards from the same line. You need two PCI-x connectors on two different/separate lines coming out of the powersupply. If that is the case, you know they are on separate power rails. You can also read the schematics in the instructions that come with your gear to make sure. Link to comment Share on other sites More sharing options...
Cobalt May 13, 2006 Share Cobalt Member May 13, 2006 Heheh...I thought that went without saying. Auggy did want to know about finding out if it had seperate rails so I suppose it all works out in the end. Link to comment Share on other sites More sharing options...
