Will a seasonic s12 500W be enough for:

A8N32-SLI, 2x 7900GT, AMD opteron 170, 2 fans, one HD, no soundcard, 2 DVDs

Look to the sticky at the top of this forum for several power usage calculators. Are they prefect in judging your needs? No, but close enough! That way, you can look at the specs of what you are about to buy, finger out how much less it will give due to extra temps at the top of the case and then decide for yourself if it is the power supply for you.

I did, it came out to 551W. A seasonics s12 600W is hellza expensive. I heard the 500W model is fine for SLI

unless you want a silent PC, go with the seasonic

I don't know how silent this setup would be in accord with how effective you would cancle out noise with the seasonic:

A8N32-SLI, 2x 7900GT, AMD opteron 170, 2 fans, one HD, no soundcard, 2 DVDs

ROFL

seasonic with this rig: RIP OFF

Going against the calculations is what Las Vegas calls betting against the house. Still, I underatand the concerns of ok, which 600 watt power supply are they talking about? I can find you ones that cost down to $50.00 U.S. and no, they don't deliver near as much power as a high quality 500 watt power supply. added to that is are you really pulling that much power? Still, let's take a look at the specs, which is all that matters on what you wanna get...

500 (S12-500):


+3.3V: 30A / +5.0V: 30A

+3.3V & +5.5V Combined: 180W

+12V1: 17A / +12V2: 16A

Total: 500W

First rail is big enough on the +12 volt side os life, but for the graphics card you are running and everything else, is the second enough?

Also, I'm not too fond of this limiting factor...

+3.3V & +5.5V Combined: 180W

Some kid who posts in these forums showed me a 600 watter that blew me away with its specs, but for the life of me, I can't remember the name of the power supply. And it was cheap too!

Here's the power supply I have and yes, it has some dedicated +12 volt rails... two of them... they are labelled... video card and hard drive, but they are just dedicated +12 volt rails...

and yes, it is quiet and I mean whisper quiet!

Show me a system that uses over 180W on the 3.3V and 5V rails.

PLEASE LOOK AT MY SIG, PEOPLE

Three posts in a row. Seriously, do you know how to edit your last post, and put your information in that one. I understand you are working on your PC++ and all, but it is all the same idea...

And what did you add to this thread? Thank you.

As for the Silverstone SST-60F ST60F 600W Modular SLI Power Supply it rocks.

180 watts of 5.v and 3.3v power is a limiting factor? Most systems don't draw 180 watts total; you can forget about the 5v and 3.3v rail.

To the OP the 500 watt Seasonic is more then enough; if I had to guess I say you are looking at 350 watts peak.

I didn't say it was THE limiting factor. I was saying it is something to consider, especially as mommaboard, CPU and video cards get more power hungry. And besides, Howie asked...

Show me a system that uses over 180W on the 3.3V and 5V rails.

and I did, so what I gotta do here, come out with a thesis project on each and every thread?!

I didn't feel the need to comment about the content, as it would just be a repeat. Silverstones are excellent PSUs, and I agree. I just mentioned that he doesn't need to do three posts in a row, when a simple edit would have worked just fine. :)

Most current parts don't really use the +3.3v or +5v rails at all. The +12V rail(s) get the most power draw. The S12-500 is quiet, efficient, and very powerful. Go for it.

No, but I want to see some numbers. You're obviously confident that your old S478 Prescott system pulled over 180W from the 3.3V and 5V rails... did you measure the power draw?

EDIT: I'm probably asking too much. I'll settle for a link that shows the power requirements of a S478 Prescott CPU from the different rails.

Didn't bother to because...

ABIT said so

Intel said so

OCZ rep told me in person.

and if you haven't noticed yet, they are a whole lot smarter than me, so. like I say, no thesis needed here! Want proof? Ok, I go measure it and yes, I have a multimeter. I am measuring amps. so that's a bit of a hassle and then because it's more than 20 amps I need to buy an adaptor for my multimeter and well, life is too short! I go with what Electrical Engineers say by the very companies who made the parts in the first place!

If your going to continue to post and offer people your recommendations at least educate yourself first....

Start with this.

Looks like you already have the money why not just buy the 600W? the seasonic 500W should be fine though.

I don't have an idustrail strength amp meter. I simply don't need to read all that dirarrhea! I will, but wow! what a waste of space!

The 478 pin board you show is a Northwood, not a Prescoot setup! Ding!


It's got a lousy 6 pixel pipeline video card which draws much less, not just in +12 volt power than mine, but other values as well! Ding!

At this point, I'll stop reading your useless link and defer back to the Electrical Engineers who made my gear in the first place!

Well, tell me where Abit and Intel said so and I'll shut up.

There isn't much difference between the S12-500 and the S12-600 in terms of amps. You can save some money by getting the S12-500.

Intel EE rep said first that the Prescott. 3.2 GHz CPU used 120 amps. Then later, he admitted to 130 amps. Then add to that people sick enough to Peltier the thing and run higher voltages and 140 amps is not unheard of in that situation.

ABIT confirmed the later numbers and said get something that can put out 200 watts total on those combined rails to run an ABIT IC-7-MAX3 mommaboard with that CPU and an 800XTPE along with all the hard drives and Audigy 2 ZS card.

I knew this would end up being a thesis!

Now where's my degree?!

ABIT confirmed the later numbers and said get something that can put out 300 watts total on those combined rails to run an ABIT IC-7-MAX3 mommaboard with that CPU and an 800XTPE along with all the hard drives and Audigy 2 ZS card.

LOL... You are so pwning yourself here buddy. I'd quit while you are ahead. What you are saying is that the Prescott 3.2GHz CPU uses 1440 watts?
