Are you not capable of adding up your consumption rates, and deciding
for yourself?

The track record on hand calculations, isn't all that good :)

Even some of the power estimation web pages, were off by
a factor of two.

*******

The best source for video card power, used to be Xbitlabs.
But they've stopped doing the measurements, so are no
longer my first source of info.

The manufacturer values, makes things a bit complicated.

http://www.gpureview.com/Radeon-HD-6850-card-636.html

Max Power Draw: 127 W

The estimate should end up being conservative in terms
of picking a power supply. The card likely doesn't
draw that much power.

The rest will be easier to estimate. I allocate
50W for motherboard and RAM, but YMMV. 300W plus
a few storage devices. Call the total about 350W
or so.

*******

Before buying an OCZ, some part of OCZ went bankrupt, and
Toshiba bought the company name (wanted the SSD stuff).
I don't really know what happened to warranty responsibility
for remaining product lines like PSUs. That could be why
the supply is available at a lower price.

http://www.frozencpu.com/products/8...Modular_Gaming_Power_Supply_-_OCZ600MXSP.html

+5V @ 25A
+12V1 @ 25A
+12V2 @ 25A
-12V @ 0.3A
+3.3V @ 25A
+5VSB @ 2.5A

The combined 12V1/12V2 limit is 42 amps. The video card
and CPU would be 250W (rough ballpark) or 21 amps. Plus
the storage devices use a little bit of that.

http://ocz.com/consumer/psu/modxstream-pro-500w-700w-power-supply/specifications

It passes a quick smell test.

The OCZ power supply section, is the previous PCPowerAndCooling
company. A company that contracted out construction of supplies,
but seemed to be on the ball when it came to not shipping a lot
of crap. Lots of companies in the PSU industry contract out,
but many of them are willing to ship shoddy goods to make a buck.
PCPower was better than average (in terms of initial product
quality, and also in terms of customer support). I don't know
where the staff and skills will go now though.

Thanks, the eXtreme Power Supply Calculator Lite came up with
something quite different from Asus' Power Supply Wattage Calculator...
http://support.asus.com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us


eXtreme Power Supply Calculator Lite: 446W

Asus' Power Supply Wattage Calculator: 600W


Okay, which one should I believe? :)

The last time I tried the Asus one, it had a "resolution"
of 50W. When the Asus calculator ran, it rounded to the
nearest 50W. That's why your "600W" number is so round.
You can add an extra 5W electrical load, and the final
number goes up by 50W (due to the rounding).

The eXtreme one is still a bit high, but it's giving you
the go-ahead to buy the 600W supply.

In terms of "getting good" at calculating these things,
you can use a clamp-on DC ammeter to validate your
estimates. I own such a meter here. It uses a Hall probe,
and no wires have to be cut to use it. Some of my
"round numbers" come from using that thing. My only
problem, is I no longer buy motherboards, so have no
recent information to share.

As an example, an optical drive (CD/DVD burner) has
a name plate rating of 12V @ 1.5A. Yet, if I stick a
CD in the tray, and run the spindle motor at high speed,
the clamp-on meter reads 1.0 amps. If it was a BlueRay
drive, it might be slightly higher. (At least, the BlueRay
nameplate value is higher, for what that's worth.)

*******

The cheapest "fun" you can have, is spend $20 or so on
a Kill-O-Watt meter. Build up your computer, using the 600W
supply. Then use the Kill-O-Watt to measure the actual power.
You'll find it will be less than the 446W from eXtreme, and
less than the number I came up with. When measuring the power,
you want a 3D game running on the computer screen, plus perhaps
one copy of Prime95 running.

Depending on where you're measuring, you are also making
a measurement of the "inefficiency" of the switching power
converters. The power supply contains a switching power
converter (85% efficient). The VCore around the CPU socket, might
be 85 to 90% efficient. When measuring with the Kill-O-Watt,
a 125W processor might end up using 125W/(0.85*0.85) just
to give some idea what impact the various conversions
are having. The value at the wall, will be higher than
the PSU rating (it takes 600W/0.85 at the wall or 705W
at the wall, to make 600W inside the computer). As long
as you're careful about how you interpret the Kill-O-Watt
result, the Kill-O-Watt makes a no muss no fuss way of
gaining some actual feedback, about how bad your
system is on power. The power will be a lot higher while
gaming, whereas it could be 100W at idle.

http://www.amazon.com/P3-International-P4460-Electricity-Monitor/dp/B000RGF29Q

That's for people who want some amount of actual info
about their computer build, but without the usage of
"wires" or "probes". And one of those for $20 or $25, is
a lot less than a clamp-on DC ammeter.

This is the style of clamp-on DC meter I got a number of years ago.

http://www.amazon.com/Extech-380941-200-Ampere-Resolution-Clamp/dp/B00023RU0I

http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000058028.pdf

I use the 40.00 Amp DC full scale range on that meter, for
usage inside a computer case. You grab a bundle of similar
colored wires on the main ATX cable, stick them inside the
jaws of the meter, and the meter "sums" the current in
the wires and reads it out. The 3.3V and 5V rails use
multiple wires, and you just stick all the wires within
the jaws to get the total value in one measurement. I
can tell instantly how much CPU VCore is using, just
by putting the jaws around the two yellow wires on ATX12V
2x2 connector. Then, I have to correct the reading, for the
85-90% efficiency of the VCore conversion, to conclude the
power the CPU is using. As measuring the yellow wires, also
includes the heat wasted on the VCore components.

It is simple addition, not "a calculation" (inferring complexity).
The elements ALL have consumption declarations.
Even some of the power estimation web pages, were off by
a factor of two.

No need to estimate. A product does not get a CE cert without such a
declaration, so they ALL have it.
*******

But they've stopped doing the measurements, so are no
longer my first source of info.

Hard to trust their "measurement" method as well. Especially if it is
not clearly defined.

And no, watching the AC consumption jump does not suffice.
The manufacturer values, makes things a bit complicated.

You must not know much about electronics. All the declarations for
all the devices are correct.

The power supply itself is the ne device that does NOT consume what it
is rated at UNLESS it is fully loaded. Not very complicated at all.

Sorry... I do not do ATI CRAP.
Max Power Draw: 127 W

The estimate should end up being conservative in terms
of picking a power supply. The card likely doesn't
draw that much power.

You are not very bright. It very likely does, and "at idle" (if a
video card could ever be such), it very likely consumes a good 85% of
that full bore number.
The rest will be easier to estimate.

Again... there is NO NEED to estimate anything
I allocate
50W for motherboard and RAM,

Not too bright. The cpu alone declares 125W.
but YMMV. 300W plus
a few storage devices. Call the total about 350W
or so.

AND the power supply one fires such a load with should be nearly twice
that in capacity.
snip unrelated crap.
+5V @ 25A
+12V1 @ 25A

and CPU would be 250W (rough ballpark) or 21 amps. Plus

All considering correct guesstimation AND maths. I have doubts on
each ability, and the results thereof.

A completely retarded crack.

Modern RoHS lead free PCBs are soldered up HOTTER than the old 63/37
process. They typically have 'burnt' smells associated with them, right
off the line. That is before they ever even get any power.
The OCZ power supply section, is the previous PCPowerAndCooling
company. A company that contracted out construction of supplies,

EVGA are the masters.

I do not expect an ATI dope to believe it though.

Too much retarded cross-posting by the OP or others in this thread
too.

Thanks (Guru Paul), my PSU was purchased (around June 2012) before
Toshiba's acquisition of OCZ (around December 2013).
So, hopefully, the PSU is of good quality.

Sorry, I don't know how, which is why I am asking.

There are declarations on the products you listed. If you already
have them installed, neither you nor we can sum up for you, since we do
not know what your stuff uses either.

My i7 hex core and X79 Dark Mobo and GTX650Ti all use more than yours.

I have a 750 Watt gold series supply. Your 600 Watt choice is very
likely plenty sufficient. Spending less could be risky and getting
bigger probably not needed (unless you plan to use it again on a future
build)(though it would likely use less then).

Thanks, I was nervous about using the 600W PSU but no longer. :)

Yes it is. It is also of above average quality. A 450W-500W PSU is
sufficient for your system.
