How much power is recommended for an X58 based system

[pvdbogaard]

Plan to build a new system, based around Gigabyte X58 UD5 motherboard and Intel I920 CPU. Will try to overclock.
Grafics card either an single nVidea 9600 or 9800GT 512MB version
Couple of harddisks (maximum 4). DVD r/w. Maybe extra DVD player or Blueray.

System will not be used for gaming.

Thinking about Coolermaster Realpower 620. However not sure if this is enough. Advise appreciated.

Thanks
Paul.

620W is more than enough

[Lemmy]

I would recommend a Silent Pro M600.

coolermaster sucks, too much ripple. Get a seasonic or PC power & cooling.

Um...the Silentpro that Oklahoma Wolf Tested, had under 40mV of ripple on the 12V and under 10mV on the 3.3V and 5V....that is much lower than was tested on the PC Power and Cooling Silencer 750 or any of the Corsairs. (including those made by Seasonic)

Negative.

[HOOfan_1]

look at the ripple suppression on the Acbel built Real Power Pro 750W

Excellent.

Pretty sure the Real Power 620M is also built by Acbel.

Paul.The system you describe will never use over 250W's & probably a lot less, so a top of the line 500W unit with up to +12V@40A@40C/50C would be ideal for cool & quiet computing with plently of overhead for transient response & future expansion.

Some good options would be:

CORSAIR CMPSU-520HX 520W Rated@50C
Max. Combined: Acts as a Single-Rail +12V@40A
+3.3@24A,+5V@24A,+12V1@18A,+12V2@18A,+12V3@18A,- 12V@0.8A,+5VSB@3A

+3.3V@24A,+5V@24A,+12V1@25A,+12V2@25A,

Good Luck!

Never more than 250W? Understood the I720 already takes 135. Hope to be able to overclock it to 3.6GHz or higher. This should increase power consumption a bit.
Graphics card takes a little less than 100W. Initially 6GB DDR3, likely 12GB soon. Read somewhere the motherboard too (specially the chipset) likes a bit. Say a 100W. Harddisk takes 25W. Four of these is another 100W.
This already is 450W. One or two DVD players/writers and getting close to 500. Were is my error?
Thought taking 30% extra would be beneficial. Longer life maybe? Just guessing here. That brought me to 620W. Not sure what the processor will take when overclocking.

Thanks
Paul

PaulWhere did you get your numbers?

25W for an HDD? Are you running 15K RPM SAS?

Max thermal spec requirement for CPU?

100W for 9600 & not gaming?

Large power requirements occur during demanding operations, like high-end 3D gaming, that you say you are not going to do.

How are you going to max out a quad CPU with HT & your video subsystem without high-end 3D gaming?:confused:

EDIT:

AnandTech measured these "at the wall" during high-end 3D gaming: http://www.anandtech.com/video/showdoc.aspx?i=3517

Now if you are going to use a TEC or phase & looking to OC to 5GHz+, we are probably talking a 1KW Single Rail!

[Tazz]

Well my i7 920 at stock will do almost 200W at Windows idling and under 100% CPU load I hit 250 ish. On the OCing side idle is 220 ish and load is 330 ish at 3.87 GHz and I am also running a GTX 295... Yours should be less with the video card options you spoke of.

Those are all calculated with me getting 80% efficiency.

[Tazz]

Figures are measured at the wall with a Kill-A-Watt... then calculating in the 80% efficiency.

[Hondacity]

i'd go at least 800w...

50% of 800w..is the sweet spot for your setup

i've been benching with my i940 (overclocked)..and the cpu alone is a power hog(130w-300w-dc alone)...let alone your gtx295

i prefer loading my psu to around 50% of its rated capacity..well thats just my opinion...

[Tazz]

Mine isnt the one in question, I was just providing some actual figures on a 920 for him to see.

I normally get a ballpark figure of my power draw and then choose a PSU that will give me maximum efficiency at idle loads.

[davidhammock200]

AnandTech Power Consumption Measured at the Wall (http://www.anandtech.com/video/showdoc.aspx?i=3517&p=13)

Now this is a high-end i7 during with NO OC'ing &
it shows well under 300W for GTX260, GTX260 Core 216 & 9800GTX.

With a 295 it shows 378W's.

OP says no gaming & lower-end graphics, so I don't see how he is going to max out his CPU or GPU, and I know for a fact, that Corsair HX520 will power just about any single GPU system, however far be from me to "under recommend" so go with one of the following.

CORSAIR CMPSU-620HX 620W

High Power, High Quality & still Low Priced!

[Hondacity]

again at least 800w...

whats connected on my psu.

1. mobo
2. 3x2gb ram
3. i940 @ 4.3ghz with HT on
4. Evga gtx285 superclocked.
5. Velociraptor 300

all fans and water cooling are on separate power supply...

lowest wattage i can get from my system

AnandTech Power Consumption Measured at the Wall (http://www.anandtech.com/video/showdoc.aspx?i=3517&p=13)

Now this is a high-end i7 during intensive 3-D Gaming with NO OC'ing &
it shows well under 300W for GTX260, GTX260 Core 216 & 9800GTX.

With a 295 it shows 378W's.

Also quoting that article.

All these results are taken at the wall (total system power) running the 3dmark Vantage POM (parallax occlusion mapping) shader test. This test uses very little other system resources and focuses on the GPU. This means that the numbers you see here are LOWER than total system power while playing a game -- often by more than 50W and sometimes 100W, depending on the game, benchmark and system.

Hondacity, what are you using to achieve CPU load and CPU & GPU load? Hell I can't break 500 Watts at the wall.

[davidhammock200]

Hondacity, what are you using to achieve CPU load and CPU & GPU load? Hell I can't break 500 Watts at the wall.Fine, but our OP says he is not gaming.

However here is a deal too good to pass up!

$70 after MIR + FS @ ZZF
http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=10005611

Or in-store at Microcenter $80 after MIR (can local pickup)
http://www.microcenter.com/single_product_results.phtml?product_id=0264292

That is the best d@mn PSU deal going!

Single Rail +12V@60A@40C

Excellent Review at [H]ard (http://www.hardocp.com/article.html?art=MTM2OSwsLGhlbnRodXNpYXN0)

[pvdbogaard]

thanks for all the feedback. BTW I am in Europe. Guess the free shipping is off :mad: Must say it looks to me there is no real consensus on this topic.
However most will agree that a 600-ish Watt PSU is adequate (although for some also overkill).

The only games I play on occasion are solitair(ish), Tetris, Loadrunner
PC will be used for digital image manipulation. And route calculation for long motor cycle trips. I try to create a Hackintosh out of it. Perhaps one or two V-raptors will be installed at some future time.
Not planning SCSI nor SAS.

Also likely another boot partition for OpenSolaris/Linux to do some open source related performance tuning and tweaking (Database related). Here many parallel threads will be used. So the CPU will use all (hyper)threads it offers. GPU only for 2D work. With the usual nice stuff that Mac OS/X offers.
(OpenGL and such).

Reread http://www.anandtech.com/casecoolingpsus/showdoc.aspx?i=3413

and decided to go for 850W PSU. It looks efficient in the range my machine to be will operate in. For the time being I wil not use the PSU at full capacity but it does run more silent compared to the 600ish PSUs at the consumption rate of interest.
And I might be ready for the future with a little extra.

Thanks again!
