what psu for a8n-sli deluxe is everyone using?

[Creideike]

Running my fine with a Aerocool Aero Power II, and the Thermaltake 20-24 Pin connector. It been working great and looks great with solid rails, however I have not directly measured them directly.

 

[mrscintilla]

enermax eg466p-ve-24pin. It runs soild, and very quiet under several sessions of prime95.

Oddly, It has a very sligth plastic-burning smell, probably from heat on some excessive glue around the big capacitors. I actually opened the cage and looked inside.

So looking at PSUs now to replace my current pos, the modular feature looks really nice. I think I'm set on the OCZ ModStream 450w, everything looks good. Just wondering, its a 24 pin main connector right?

Edit: And is it dual rail or whatever I'm reading about now? From what I've read its not "that" big of a deal, but I think I'd prefer to stick to single rail.

 

[SenorBiggles]

another Neopower here. It does the job.

I agree this does look like a nice single rail PSU that should be more than adequate for me. I plan to run 2 6600 GT's in SLI with a Winchester Athlon 64 3200. Here's the product sheet:

http://www.ocztechnology.com/p...ModStreamSpecSheet.pdf

The little picture at the bottom of the 2nd page looks like a 24 pin connector to me. And according to the product sheet, the 450 Watt cranks 26 amps on th +12V. That should be enough to power even an Athlon 64 FX with 2 6800 Ultras in SLI according to the motherboard manual specs for the A8N I posted above. So unless you are planning on actually running that configuration plus a few hard drives and other peripherals, the 450 Watt should be fine. I will probably get one of these too. Also, I don't really know when the motherboard manual came out in relation to the Athlon 64 Winchesters but they should have less of a power demand than the previous 130nm chips.

I personally do care for how high my elctricity bill is, thatswhy i bought AMD Winchester and not Intel and so i wont now buy a 600Watt psu that will only run at 40% usage with a resulting very bad input-output power relation. Its not cool to have 600Watt and only using 270 of them. Makes no sense and costs real cash for electricity. just needed to mention that.

A 600W power supply is not always drawing 600W from the wall...
People get these power supplies hoping they will last a while. Plus many of those 420W power supplies don't have much amperage on the 12V, which is what matters these days.

Another Antec Neopower user here- no problems. My system is probably a lot less loaded than others here, though:
ASUS A8N-SLI
A64 3500 Newcastle
Zalman 7700AlCu
250GB SATA Maxtor Ultra 16
BenQ 1620
TDK CD burner
Chaintech 6600GT
4x 80mm Sunon case fans

No problems so far except WinXP wouldn't install off of the BenQ, had to install off the CD burner. WTF?

 

[quik]

Ordered a Neopower, which i can't cancel... didn't realize the problem with the dual rail psu's :/

Will be using it with 1 6600GT (2 in the future in SLI)
6+ HDS
1 Optical Drives
2 x 120mm fans etc..


I will probably have power issues cause of so many hds?

What would you guys recommend... i can grab that OCZ Power Stream 420w (+12V(30A) but is 420w enough for all the hds and SLI ?

 

[ahurtt]

Even with 2 6600 GT's you don't need all that much power according to the motherboard manual.
See above about 9 posts where I posted the power requirements from the motherboard manaul. It says this:

Athlon 64 3400+ and 2x 6600 GT you need 350 Watt PSU with +12V > 17A

So the question is, what processor are you using along with the other stuff? I am assuming this spec is the minimum you need to power a basic non-overclocked system (1-2 HD's 1-2 optical drives). And this spec also is probably based on a 130nm CPU. You can save a little bit of juice with a Winchester 90nm. As long as you have at least one rail on that dual rail PSU that meets the above requirement you should be ok I guess. If not, better get a single rail. But since you are running 6 HD's you'll need to figure out your total power need and decide if your current PSU will do it. . .since you are now only running 1 6600 GT you might be ok. Dunno really. . .let us know what happens.

Using a 3500+ (Newcastle 130nm)....

I did just order a Antec True550 which is single 12v rail which has 24a and a max of 30a.... so that should cover me in the worst case scenario... I have to RMA the Neopower 480 (which was 15a or 14a on each of the 2 12v rails) and it had already shipped doh... it will just not cut it specially when i do get SLI running later on...

Hate to pay so much for a new Neopower and then its not really gonna hold up if not now later at some point.... would be a 110$ down the drain. Plus the 550w will be nice since i may have 8 hds in there if i can make them fit.

How many watts does a 7200 rpm hd use roughly?

There was a website that used to add it up all for you, you just picked how many hds etc... and gave you what size power supply was needed. Anyone have that link..? I couldn't track it down on google...

Thanks

Enermax Noisetaker 701AX. (600W)

Overkill but I was able to get it for $110 AR. Runs very quiet and cool.

(The blue color also matched my case!)

Dual rails there but it does have +12V1@18A, +12V2@17A so should be good

I snagged this link:
http://www.bleedinedge.com/gui...ect/psu_select_04.html

off of this thread:
http://forums.anandtech.com/me...id=29&threadid=1494448

which is a big debate over whether or not dual rail power supplies are really the cause of problems people are having with the A8N. Some arguments make sense but at this point it is still theoretical really as to whether or not these really NEED good strong single rail PSU's in all cases. I am maintaining that there are some cases where 6800's in SLI is not a factor and power demands are lower in general where a dual rail PSU will work fine. All theoretical now though until somebody actually posts hard proof.

OCZ Modstream 520w. No problems, period, since I assembled the system.

less then 10W.

e: guess u was looking for this link: http://www.jscustompcs.com/power_supply/

it says one hd eats 25Watt, which is ridiculous, dunno why they write this crap, but its not true.

 

[quik]

Thanks

Aspire 500w see-through. No problems at all.

 

[Auxano]

Where did you get it for $110?

Central Computer had it online for $140 (Found it using Froogle) with a $30MMIR (valid thru 12/31/04)

I was going to go with the OCZ but there was too much difference in $.

Anybody know anything about this power supply:

My friend has his a8n-sli and one 6600gt and will not be overclocking. He is intent on not spending over $50 on the PSU (I keep telling him he's insane). It does claim 20A on the +12V rail, so that is above the 17A minimum requirement....anyway...

This exactly what I want, and I'm glad it's working well for you.



Edit:

However this Athena looks pretty good too: http://www.newegg.com/app/View...A=1&page=2&listStyle=2

Any opinions?

 

[Muhadib]

Just orderd a Seasonic Super Silencer 460 to replace my dual rail Fortran Blue Storm 500. Judgeing from the information in the fourms and a few reviews I think it will work nicely for my needs.

Mad Dog is some sort of "own brand", which means you'd be mad to buy it unless you know who built it.
