S12 430 enough power????

Post by piotrgurin » Sat Apr 16, 2005 5:37 pm

I'm getting my butt kicked over at dfi-street.com

I believe this site and you guys more than them.
Here's the link to the thread over there that I posted.
http://www.dfi-street.com/forum/showthr ... ge=1&pp=15

Take a look at tell me what you think regardin the 430 being enough power.

There is a reason why there are two different forums. There is more than one religion in the world.

Read the emperical data in the PSU Fundamentals articles about actual system power draws. Do the math for your own components. Personally, I'd trust actually testing data over the hearsay bs at a mobo manu's forum, but that's just me

If they say their boards won't run with anything less than 480 watts, then buy a different board...not like the DFI is anything special anyway.

More likely their 480 watt "requirement" is the result of dealing with people buying uber-cheap, over-spec'd PSU's and then complaining about it.

First thing you have to understand is why DFI would recommend a 480W power supply. A lot of power supplies out there that are rated "450 watt" put out much less as they heat up, the cheapo power supplies can't handle high heat/high current loads.

Your Seasonic can handle both easily and you are not loading the computer down much at all. I am running a system similar to yours (my mobo uses the ATI Radeon XPress though) I use a Zalman 400W PSU with no problems, the fan idles along silently under the light load. Granted, my X700 Pro does not suck as much power as the XL800 but it can't be 30 watts more than the X700 Pro. I also am running two hard drives and a TV tuner so it is close to what you are running.

I would rather have a 430W Seasonic than a "520W" Deer or Maxton (or whatever they are called) It is much easier for manufacturers to quote a high output power supply than to quote a quality one. Slap the computer together, run video and CPU benchmarks at the same time for 12 hours and enjoy the stability. If you want, read the amount of electricity drawn from the wall... Relax, you spec'ed the power supply well.

Hell yea!
You guys are awsome.
I know what you guys are saying because I read the PSU article on this site a couple of times.
I guess those people at dfi-street just don't know what the real deal is. heheh

Thanks again to every1 for taking the time.

Not everyone shares the same reality. On this forum, reality is silence. On the other forum, reality is power. Anything posted on either forum must be considered in light of these differing perspectives about "reality."

RG and AG recommended the 480W+ because well, they've probably tested enough DFI motherboards and seen problems with the lower wattage PSU that could have been easily solved by steapping up and getting a higher wattage PSU (e.g. OCZ PowerStream 520/600)
They're making the common assumption that all PSUs deliver what they say they can. I'm sure they wouldn't have any problems with a 450W OCZ but they're not willing to try it, and they're not interested in how the guys decided 480W was enough.

Wow, those guys are dfi-street are crazy. Just for reference, I'm running a p4 3.2C mildly overclocked with a 9800xt, a gig of ram, dvd burner, hd, fans, sound card, etc...on a seasonic 250W! your cpu takes a similar amount of power, your video card may take slightly more but not way more. I think you'll be more than happy with the 430W seasonic psu.

Power supply vendors have a nasty habit of rating their power output at 25C. As you know there are very few users that can maintain an internal PSU temp of 25C while operating at idle much less under load. As temps go up efficiency goes down which can bring even a very good PSU to its knees. I'm sure you understand why it isn't in the users best interest to take your advice over the DFI engineers.

But then you guessed it anyway :!:

As much as I like satirizing idiocy, this thread has started to get noisy and pointless. Keep it sane or this thread will be locked.

Any modern quality 430W power supply is plainly enough and then some for the setup in question. The recomendations of a bigger power supply are based on using an old design, low quality power supplies. The 480W recomendation is not bad, it is simply intended to minimize problems for for even the least educated consumers. Skimming over the posts there I do think you should pay attention to the RAM recomendations though, that is the kind of mobo/chipset specific that type of forum is likely to be helpful on avoiding.

Sorry, must have been temporary insanity :roll:

Anyway, the 430W S12 will most definately have anough power..

My DFI board had a sticker on the 24-pin connector saying what amperages you need on the 12V line with different CPU/GPU combos, i dont remember what they were though. And i seem to have lost the pictures of the mobo before installing it, well, somewhere on my computer, a word of advice to you all, if you have 5GB of pictures on your computer try to name them so you have some chance of finding what you need :lol:
