680watt psu question

No. Assuming it really is capable of 680w (aspire, right?), and your pc only draws 300w, and it has an efficiency of 75%, that means you're drawing 400w from the wall. Now if you had a supply which was 86% efficient, you would be drawing 345 from the wall.

You are trusting all of this to an Aspire?
Aspire PSU's are among the worst, they don't even pretend to meet the minimum ATX/Intel/AMD specs!
Highly recommended that you replace ASAP!
thankyou BBQ fo that because i didnt know how to calculate it myself.
As for trusting aspire.... it hasnt done anything wrong and it should last me my life of my comp because this might be the last Gaming PC i have until im done with school...( good enough for counter strike, azureus, firefox, & microsoft office )

It's not a 680W PSU, Aspire overrates them to get ignorant customers to buy their product. The keyword in that sentence is should. So as of now, it is a gamble. You spent big on the hardware yet cheaped out on the power, awesome!Saki630 said:As for trusting aspire.... it hasnt done anything wrong and it should last me my life of my comp because this might be the last Gaming PC i have until im done with school...( good enough for counter strike, azureus, firefox, & microsoft office

I think that's a meaningless statement...If they did pretend to meet "specs" would all be well with you? Shouldn't the question be do they or do they not meet specs? Or how about, do you or do you not believe power supply labels??? Go to the Youngyear site and look at the specs for the Aspire units....then go to the Seventeam site and look at the specs for the EPS series and come back and tell the world how Seventeam doesn't even pretend to meet specs <eyeroll>

You truly are ...Makalu said:
ATX/Intel/AMD specs all require that the +12V have load regulation of +/-5%,
except for peak load (less than 2 seconds).
Aspire even publishes that their +12V spec is +/-10%,
which prevents RMA's with less than a 20% (2.4V) swing;
ie: the difference between their highest & lowest recorded voltage on the +12V rail.
So instead of +11.4V to +12.6V, their spec is +10.8V to +13.2V.

I'm aware of the Intel Guideline and Aspire labels...Youngyear lists the voltage regulation differently and if you go to their site you'll see this. I'm just not seeing any Aspire labeled units that actually don't keep their voltages within specs. In fact pretty much all power supplies these days except for the very cheapest case units don't seem to have any problem at all "meeting specs". Seventeam publishes that the load regulation on 12v2 is +/-10% on the Sytrin/Masscool unit but I sure haven't heard of any that couldn't keep it within like 2% or less...mines under 1%.
Also, if I'm not mistaken at least one of the Aspire units is labeled as having a +/-3% tolerance...so much for blanket statements. If you have evidence that they aren't within specs fine...just say so and drop the pretend nonsense. According to the guideline a unit is supposed to shut down if it goes out of spec...have you heard of people buying an Aspire that had voltages out of spec and were unable to get an RMA on the unit because of the labeling?
If they are within specs but the 10% label is how they over rate the total wattages then say so. If you think some kid with a system drawing 300w will ever find out the hard way that the 680w beastie will only do 500w or whatever then fine...caveat emptor i say. Just trying to help you clarify reality...didn't think I was being insulting...usually I leave no doubt when i am
And before the onslaught of kiddies here comes along I'll say this...I don't work for Aspire...never owned one...not anybody or any brands !!!!!!. I speak the truth and I have bigger fish to fry elsewhere...good luck sorting quality from crap and the nether world of mediocre power supplies that work.

Obviously there's a bit of a misunderstanding here....
If I may....
Since the 680W is based on a 550W platform, we have to look at how we get 680W and 550W.
I'm sure the Youngyear can stay within -/+ 5% with under a load within it's spec as it's rated for up to 550W use. Perhaps to push the PSU to 680W, the 12V rail had a tendency to drop below the 5% and more towards 10%. Thus the -/+10% statement.
Of course, I couldn't prove this in my review because if I put anything more than 34A on the combined 12V rails, the PSU shut down. So I wasn't able to put more than 566.8W on the "680W" PSU. Perhaps the room was too warm at a balmy 25C. Who knows.
But more than anything, voltage regulation or not, you just have to look at Youngyear's track record. They simply don't have a tendency to last. The odds are against catastrophic failure, so I wouldn't jump to replacing it ASAP. Any PSU can potentially blow up, so replacing one that seems to be working fine is probably going to increase your odds of a failure.
