GTX 480 Power Consumption - Question

[xXedixXx]

Hello,

I'm just a bit confused as to how much power (W) I should be looking to get for this card....

I've seen that under a full load this card's power consumption can get up to 475W:

http://www.hexus.net/content/item.php?item=24000&page=15

However, on the NVidia website it says the "Maximum Graphics Card Power (W)" is 250W:

http://www.nvidia.com/object/product_geforce_gtx_480_us.html

So....

Should I put this graphics card down as requiring 475W or 250W?

My power requirements list so far (if 250W):

Processor: 130W
Motherboard: 220W
Graphics Card: 250W
Hard Drive(s): 30W
TV Card: 21W
DVD Drive: 16W
Fan(s): 13W
Total: 680W

My power requirements list so far (if 475W):

Processor: 130W
Motherboard: 220W
Graphics Card: 475W
Hard Drive(s): 30W
TV Card: 21W
DVD Drive: 16W
Fan(s): 13W
Total: 905W

As you can see, it makes a huge difference as to what sort of power supply I'm going to be needing...

Thanks!

If you look at those charts again, you should be able to figure it out. The GTX480 will take about 250W. (I think it uses more then its rated for, but 250W is close.) A SYSTEM with a GTX480 in it might take 475W, but the GPU is part of that system.

What motherboard are you looking at that takes 220W? Those should be 50W or less. Fans are usually 3W or less as well. I'm currently looking at an 80MM case fan thats 12V @ .14A. That puts it at 1.68W.

Aahhhhh!

I see what you're saying... I thought it was just rating the graphics card, this is good I'm going to save a lot of money, on the PSU and the cost of running it

The motherboard is the Asus P6X58D-E:
http://uk.asus.com/product.aspx?P_ID=gFBKfNyhppW9tDbB&templete=2

The figure I was using for that was 220W because that was from a review, but I can't find how much the actual motherboard (itself) uses...

Oh btw, that fan wattage was for 5 fans @ 2.5 each, it isn't 13W each

Back in the days of NB and SBs you would see 15W or so for the NB, and another 7-10 for the SB. (max of 25W) With NB on the CPU now, I really doubt you'd see a big draw on a motherboard. 20W or so max. Your 220W figure it MUCH to high.

I'm not disagreeing with you, it's the only figure I can find. I need to know how much it uses though, it's important I don't get a power supply that's way more than I need or too little.

Know where I can find this information easily? I've tried searching etc...

To see if anyone knows.....

the system below with an OC i7 did not break 450w at stress test load. I would suggest a PSU with 40a on the 12v. Something like the corsair vx550w, Antec truepower 550w

corsair modstream 600w or xigmatek 600w would be budget options.

- Intel Core i7 920 (Overclocked @ 3.70GHz)
- x3 2GB G.Skill DDR3 PC3-12800 (CAS 9-9-9-24)
- Asus P6T Deluxe (Intel X58)

Thanks.

So you think a 550W->600W PSU will be sufficient?

My system is basically going to be:

i7 950 @ 3.06 GHz (Probably going to OC it)
NVidia GTX 480
Asus P6X58D-E
3 Hard Drives
6GB DDR3 RAM @2000MHz

Just making sure, you think 550W->600W is going to be enough?

Be okay?

A GOOD 600W should be fine. Something like a Corsair, Seasonic, Antec, or maybe OCZ.

 

[xXedixXx]

I think I'll go with the 650W Modular Powercool PSU, it's a good price and has the connectors/connections I need.

Thanks guys!

I second the Corsair, they are wounderful power supplies and have a great warranty.

 

[xXedixXx]

it will work but the GX tend to get loud at times. that site you linked has a good price on the corsair 650w (almost the same price as the corsair vx550)

This one?

Do you think the extra cost is worth paying for the quality?

 

[xXedixXx]

Alrighty, thank you all for your advice.

This is now officially on my list
