And for those who keep saying you need a 750+ watt PSU, please, stop saying that. I'm a computer tech for a low-pro computer store
What store is that....remind me to never refer anybody there.
Obviously you didn't read the link I left above for "read this" it explains why you should run a larger PSU than you NEED.
Yes a most 500-550W supplies will run his system, I am not arguing that. I am merely suggesting that to be SAFELY powered AFTER the PSU ages it is best to run a larger than needed PSU.
the way I see it is You can spend ~$75 on a 500W and replace it every year to avoid the dangers of aging. Or you can spend ~$120-200 on something larger with more aging room that will last for 5 years. Also allowing upgrades/new builds without having to purchase yet another PSU.
It's not about his system NEEDS 750W to run. A system will ONLY draw the power it needs, just because its a larger supply than what he needs does not mean it will supply all that power at all times. If my system NEEDED 750W 60A, I'D be running a 1000W+ 90-100A.
It is about the FACT that PSUs over time lose upto 30% of output ability. and that time can be as little as 1 year or as long as 5+ years depending on quality, the average is 3 years.so choice is yours, run a 500w that iwll run your system and risk 30% lose in possibly 1 year, that will most likely cost you a new VGA card and or mainboard when it goes. Or run a larger PSU and KNOW your safe even if htat 30% is lost 1 year later.
that Antec PSU you linked is a good PSU for its capacity. However it is only about a 35A PSU. If his system needs 26-30A it doesn't give him much room for capacitor aging that WILL happen and take out his system when it does.
Thus the recommendation for a 750W 60A or at least something pushing 45-50A. which will allow some room for aging and not take out that new VGA card in the near future. A good rule to follow is that whatever your power NEEDS are, buy at least 30% larger to allow you to be safely powered even when again occurs and you lose 20-30% of output ability.
as well it is not wise to run a PSU above 70% of its output ability EVEN UNDER FULL LOAD. You are best having a PSU that runs at 50-60% under normal load reaching no more than 70% when your system is under full load for extended periods. this will age it faster due to heat.
It is ONLY about the watts because watts are needed to provide the AMPs. The real thing you NEED to look at is the AMP output. because wattage can be configured in a variety of AMP outputs.
5 years ago I had a 420W Antec PSU pushing 19A, when it died it was replaced with a 410W 26A Enermax. See my point 10 less watts 6 more Amps. by the same token a 500W PSU can be configured anywhere from ~26A up to 41A.
ONLY A FOOL who wants to lose his system pays attention to just the watts, and not the AMP output.
750WA is a LOT of power, mainly since 90% of them on the market are 80+ certified, giving it a longer-lasting drive, since it's peak at 80+ is like, 825WA or some junk.
LOL...I think you are a little confused on efficiency rating.
80+ certified has NOTHING to do with how much power the PSU will put out in relation to it's peak output ability.
80+ Efficiency rating ONLY means that 80%+ of the voltage coming into the PSU from the wall will be converted watts to then provide the amp output. the remaining ~20% of power coming into the PSU is lost to heat in the coversion process which is why electric components run warm/hot.
It DOES NOT determine ANYTHING about how much power the PSU will actually put out or at what percentage of peak wattage.
It does however play a part in the life of the PSU as you said "longer lasting drive" but this is only due to the better the efficiency the cooler the PSU will operate, thus the heat will age it slower, which is critical especially if you run at peak.
Then there is the operating tempurature at which the efficiency rating was given. That too discussed prior in my last post and the link. Maybe you should read it.
or if you want something with a bit more kick,
http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005 would be more than you would ever need for a mainstream video card,
Well now your on the right track. a DAMN good PSU and yes would be ample for his needs.
LMAO....But I have to wonder....you say a 750W is "A LOT of power" Yet do you realize that the 610W PC Power in your link is actually about the same as 99% of 670W PSUs.
Thats right.....99% of companies rate a PSU at its PEAK wattage, such as most 500W PSU are 500W peak output but really run closer to 450W continuous tapping into the other 50W when needed.
PC Power is the only company that I know of (may be a couple others) that rates their PSUs at CONTINUOUS wattage. that 610W is 610W continuous, 670W peak.
It's also a 49A output which will allow some room for capacitor aging and still be safely powered, though not quite as much safety as a ~60A supply.
so really one of your own recommnedations is only 70W/ upto 5.8A smaller that what your telling us is "A LOT of power". is that too a lot of power????
