i have 2 questions:

1.this is 20pin, not 24; right?
2. +12V1 [18amps] +12V2 [18amps]; does this mean i get a total of 36A delivered through +12V?

 

[PhoenixOrion]

1. correct. you have to do a 20+4pin that's included for a 24-pin mobo.
2. again, you answered your own question.

 

[diabloII]

wait...so the 4pin is INCLUDED so all i have to do is attach the 4pin with the 20pin and i'll have a 24pin connector for my pci-e mobo?

 

[Sniper82]

Thats both 20pin and 24pin. It has the extra 4 pins that clips on making it a 24pin. As for the Amps thats sorta true. I just bought the Enermax EG495AX-VE which is about the same except mine has a couple different features. What is does is use one 12v rail that just supplies power to the mobo,CPU and video. The other rail powers optical drives,HDD drives,fans,ect. If the mobo/video needs more power you can add power from the molex's which is the second rail. Thats of course if the mobo/video has the connector.

If the mobo,CPU and video needs more than the amps thats on the first rail you might have problems but not sure. I got all that from the manual.

No, it means you get a maximum of 18 Amps on each rail. If you need 19A from one, you are out of luck!

 

[diabloII]

ohhh, ok thx for clearing all that up for me

but i got one more question.

the regular PSU with only one rail uses the 18amps for EVERYTHING on the motherboard, as opposed to this PSU which uses the first rail for ONLY the cpu, mobo, and video card, while the second rail powers everything else on the mobo (i.e. hard drive, floppy, optical drives)

also, where can two rails fit on a mobo???

Did not mean to confuse you on the 2nd answer.

Noisetaker 2.01 has solid 18A on each rail so I would not worry too much about stability issues.

The most important thing to note is that when the first 18A is maxxed out (if ever) the other rail does not automatically jump in to take up the slack.

Only if your rig has actual SLi setup that you must put the 4pin molex (additional) to your pci-e mobo from the other rail to keep the juice maintained for your graphics hog. (important power cable management I would say)

Ok, the Enermax model sited above is a dual rail PSU that supplies 18Amps on one rail via the ATX/sub-ATX connector. You are VERY UNLIKELY to need anywhere near that 18 Amps since it is all going to the motherboard (you cannot control the allocation). The second rail's amps are piped out to the drive connectors for the drives in the system. The idea is that fluctuations of power on one 12v rail will not affect the other 12v rail, thereby increasing system stability. For the most part, it is a great idea. Where you will find some people object to this is when overclocking--they want as much amps on the 12v rail as possible, and therefore opt for a single 12v rail PSU with a high amps on that rail. In a single 12v rail PSU, yes, all the amps would come through one 12v rail that is divided across ALL the power connectors that happen to use the 12v rail (eg. most of the connectors coming out of the power supply). The overclockers among us are banking on their drives not needing many amps off the 12v rail and they are trying to get as many amps to their motherboard as possible. A dual-rail PSU will sometimes limit the ability to overclock. If you do not plan to overclock, then you will have no problems, and quite possibly a more stable system--especially if you are running a lot of drives.

hehe, chicagopc, you took words out of my mouth. boils down to what you plan on doing.

enermax noisetaker is great for sli rigs.

if you plan on oc, you're better off with antec true 550 or ocz powerstream 520. (imo)

 

[Twigstir]

This, not out yet, OCZ PowerStream http://www.newegg.com/app/ViewProductDesc.asp?description=17-104-153&depa=1 has more amps on one of the rails.

I running an AMD FX-55 with 2 6800 ultra's in SLI and not sure which PS to get. My current ultra x connect if causing shut downs I believe.

Agreed, if overclocking, the OCZ Powerstream 520 is definitely the way to go--or the Antec as well, but the OCZ has, I dunno, more appeal to it. Just my personal opinion on that one!

You got a serious power hog system! Yeah, I am not surprised your X-Connect is causing you issues. The X-Connect has been rated lesser as compared to the OCZ series PSU's. In your case, I would go with the OCZ with as much amps on the dual rails as possible! OR--Edited to say, if you are not running a lot of drives, go with a high-amp rated single rail PSU such as the 520. Your mobo/video card combination is tantamount to overclocking as compared to lesser systems!

 

[Sniper82]

Unless your running sli 6800's,few HDD's,couple optical drives,few case fans and a FX chip I think 18amps on each rail would be enough to o/c without issues.

 

[diabloII]

really?

so if i get something like a silverstone 350watt PSU with 18amps on the 12V rail it wil be enough to OC or do i need 2 rails for ocing?

No that wouldnt do it. I don't know what kind of system your running but with single rail PSU's everything runs off that single rail so you need high amps on the rail(24 is the lowest I would go). With dual rail PSU's your mobo/CPU and maybe video feeds off the first rail which is 18amps(if you get that Enermax) while the rest of the system feeds off the second rail which is another 18amps. This is with the Enermax PSU don't know how others share the rails.

You can o/c fine on either dual or single rail.

 

[Twigstir]

With my system I am concerned about 2 rail power supplies. I have one HD and plan to add another, and 2 dvd players/burners.

I see falcon systems use the 2 rail enermax 600W.
Lots of people here recomend the OCZ 520
The 600w OCZ is 2 rail with 20amp on one 12v but it's not out yet and I already have problems.
Alienware uses pc power and cooling 510 : http://www.pcpowercooling.com/products/...erformance/turbocools/index_hp_atx.htm (I have not seen this recomended very often)

It's hard to decide what I should get.

That Silverstone PSU with 18amps on the single 12V rail it has is just enough for a value or mid-range system (S754 up to 3200+ perhaps, with a 6800 non GT AGP card or lower). Certainly not SLI, and I wouldn't even recommend it for a S939 system of any type. In certain situations, especially if you are going for serious overclocking, then a single 12V rail PSU with insanely high amps (like Sniper said--24 amps and above--30 amps and above even better IMHO) is the ticket. Most of the higher-end dual 12v rail PSU's (with 18Amps on each rail or higher) are also suitable for overclocking or just about anything else. It depends on what you want to do. What exactly is your rig going to look like?

 

[Sniper82]

If you have the money I hear pc power and cooling is about the best you can buy.

Your stability problems will probably come to an abrupt halt with the OCZ 600W Dual Rail PSU. Nice, and really pricey, but nice PSU.

EDIT: Edited to say you don't see the PC Power and Cooling often because of the fu#@*&ing insane pricing they have. Definitely solid PSU's, but talk about overpriced! OCZ is just as good, and cost a LOT less.

It means each rail can hold up to 18A maximum per spec, not how much amps it has. The amp amount listed under +12V total (32A for 485W model e.g.) is what those PSUs have in total. That total is split & balanced between those two rails based on power draw. For example if the components on one rail draws 17A, the other rail would have 15A left to use or if the draw on one rail is 16A, the other rail would have 16A to use.

Ya sure about that? My manual says CPU, Mobo, & SATA on one rail, and drives, floppy, & external gfx card power on the other.

As a counter argument & as you've said dual rail PSUs increase stability - multi rail PSUs increase the stability factor further. That too is important in OC'ing. With single rail PSUs, you get high amps but less stability than a dual rail PSU if those amps are heavily used. At the opposite end a dual rail PSU has better stability at higher loads than a single rail PSU but lower amps usable (in most cases).

Basically if dirty/unstable power was limiting your overclock, you'd want a 2+ rail PSU. On the other hand if the lack of amps/power was the limiting factor, you'd want a single rail PSU. Now if you want the best of both worlds and/or needed more power than the strongest single rail PSU out there (Zippy 700W?), your only sensible option would be a high powered multi-rail PSU.

Totally agreed. I am just pointing out the motivations of those people who believe the single rail PSUs with high AMPS are better for OCing. I personally believe a good quality PSU that has sufficient AMPS, whether dual or single rail, is suitable for overclocking, but in general a high quality dual rail PSU is the better of the two. Your particular setup will dictate the type of PSU that will work best for you.
