This also assumes that the specs are accurate. It is an unfortunate fact that power supplies are often rated higher than what they can properly produce.

Yea, that is what I have been reading as well.
It is a sad situation, that companies have to gip people into thinking that
Their product is something more than what it is.

So, this PSU that I have in the picture might run
550 instead of the 600? If it is the correct information that is.
(It is not a 700 :) )

Well, one last night to do, would be to research the PSU's coming from that company, and see if people are NOT getting the performance that they THOUGHT they would get from the CPU's..

I was looking at another model, and I came across this website where they tested the model back in 2010. They stated this about it. Of which went along with what you stated above.

AK680 = 680W Power Supply
This is what they said on the site.

Using the same metrics as Corsair does, the AK680 is really only a 480W PSU at best. This is what we feel is a serious problem in the industry and worldwide regulations need to be upgraded. This way consumers do not have to be electrical engineers to be able to select a suitable model.

So, dang, I mean, It is a pain to find the right thing, without breaking the bank, to get what you need.
It is becoming a complete joke. Oh the wonders of computing.

I am thinking about going with this one.
Sentey XPP725-HS
What are your thoughts on what the output is?
the reviews seem to be really good, for this one and the next one up.
It is on sale $44.99 (regular $99.99)

I will be placing an order tomorrow, so, hopefully, I can find something before then.

The article you cited is an example of what I was referring to with power supplies being rated higher than actual.

If the specs from the manufacturer on the Extreme Gear were accurate then it would really be a 650W supply.

I don't know anything about the Sentey and I wouldn't expect user reviews on a power supply to have much weight as people are generally looking at specs and not whether the supply meets them. Nevertheless, this is likely to be a reasonable deal.

Again, though, are you sure you need a supply with this much power?

Specs are deceiving....
Go with a PS at least 50% above your required PS needs.

i never found that necessary, even when calculating the minimum needed here:

Wattage = Voltage X Current. Using the specs of only the maximum outputs it works out to 640.2 Watts. What has also been mentioned is efficiency. The higher the efficiency of the power supply with the same load will draw less power from the wall outlet.

@CompProbSolv
Not really, about a 500-550 is what I actually need.

"will draw less power" and also generate less heat.

On one of my tech benches I have an outlet strip that has a power monitor. With it I can measure how much power a computer is drawing from the AC line which much be greater than what it is delivering to the inside of the computer (less than 100% efficiency). I've been surprised at how low of a draw they typically have, about 250W or so.

This does NOT take into account peaks (such as startup) or how that power is used between the different voltage rails. I'm also dealing with general business-use computers and not gaming machines with multiple high-power-draw video cards.

Thank Comp.
I am looking in on this one here.
http://www.corsair.com/en-us/cx600-80-plusr-bronze-certified-power-supply
It is $89.00 however, Amazon has it for sale for $39.00

The main reason why I am not going to with the 500W that they also offer. Is that it cost $89 for it.
Go figure.

This unit has everything that I need, enough SATA plugs to choke a horse.
It is 20+4 Main Connector, which is what I need for my board.

I am planning on upgrading my Graphics card as well, and this will give me what I need for that.
And Corsair, is a brand that I used to buy years ago, and never had an issue with.

So.
I think that I am going with this one everyone.

Any comments or feedback is welcome.
Will be placing the order within the next few hours.

In general I've considered Corsair to be a decent product for the price. Of course, as with most of use, the number of units with which I've worked is not statistically significant.

i have measured the poser consulmption also, and have not found one pc with higher consumption than 300 W - that is basic PC without a special video card
that's why i posted the free calculator - did you use it Wayne? and how much did it show ?

ASKER

Hey Nobus
It recommended this one.
EVGA 500 W1 80+, 500W Continuous Power

I have already ordered the one that I posted about earlier.
http://www.corsair.com/en-us/cx600-80-plusr-bronze-certified-power-supply

It should be in between now and doomsday.
(Amazon Free Shipping, can be a joke sometimes)

that should be fine

Hello, Guys.
Sorry that I forgot about this one.
OK, got in the new PS, and it has made this machine come to live.
Programs run better, no more freezing up.
This is a must have for anyone that needs to get a little more life from their system.

Thank you all for the great information.
The PS that I got is awesome.
