Hello!

I was planning on buying 4 GTX 480 a year int eh future, after northern Islands, hopefully for like 300$ for all.

Was wondering if this sucker could power em:

I was lookign into a HX-1000 for new build, saw this baby at the same price, couldn't pass it up.

More about : power gtx 480s

Possibly, but if you need a power supply for those, I would recommend the HX1000 - Corsair is a trusted name with a reliable product. Enermax... is not.

My personal recommendation would be to spend a little more for the quality that will last you, and do what you need, guaranteed.

Full disclosure: I am using an Antec PSU at the moment. I just think Corsair makes good stuff.

TO be honest with ya, read the reiew, that PSU rapes the HX-1000.

9.9/10 Jhonny Guru.

Quite possibly the best PSU ever made.

Caplble of 1500W.

lol so i looked on newegg site. because we don't know your cpu, mobo, hardrive and mem i did a worse case senario type thing. i7 high end motherboard.8 gigs of ram.(couldn't figure out how to do 9 lol) 2 od 2 hds and pressed enter. you need 1690 watts of power.
CPU:
Motherboard:
VGA Card: x
Memory: x
ODD: x
HDD: x



Our recommended PSU Wattage: 1690W
Please click “Find PSUs” button to find out the best results.

lol

not sure if 1500 wats is even enough.

Grrr.....

Lol the best PSu in the world can't handle 4 480s.
May 12, 2010 10:32:44 PM

I wonder if you can gang two PSUs...
Tell us when you try it - I'll be watching for the massive power outage on satalite photos

That may possibly be the most epic PSU that I've ever seen...
If you get past the price tag and the fact that it won't fit in the average ATX case, then you're good to go with that, I'd hope. And it's modular, too. :) 

That's not a PSU - that's a regulated welder!

Not really sure why you would want to have 4x480's anyway... not really any bonus in fps in having more than 2.. they just don't scale that way.

Check this review that toms just did.

Only powersupply that I found was certified for 3-way 480's found here.

Or you could looka t the new one with the driver update.

it's pretty clear that if you ahve the cash, TRI SLI still rapes.

If that won't power it, then I'm pretty sure nothing commercially available can.
It's so freaking big that they had to give you a bigger custom power cable because standard ones aren't rated high enough for it. :o 


Ha, I thought I had the best PSU ever made :( 
May 12, 2010 10:43:18 PM

Uhh, I hate to say it, but 1600w > 1500w, and $329 < $399
May 12, 2010 10:46:12 PM

Considering the fact that my microwave is 1200w, that would be like running one and a half microwaves at full power, all day long... Man, your electricity meter's going to sound like a buzzsaw...

...and yeah, I don't really see any need for over 2 unless you plan on having a monitor the size of a small building running at 10056x7040 resolution...

Not quite sure why you asked, then...

I don't know if even the Ultra 1600W PSU will provide enough power for 4xGTX480.

3xSLI does appear to be the way to go; beyond that lies madness - or multiple power supplies.

Corsair is a name brand yes, but anyone who knows anything about power supplies knows that Enermax makes an incredible product, easily on par with Seasonic. I'd take an Enermax PSU over a corsair any day of the week.

I am running 2X480 GTX and the max load I have seen in games and Seti at the same time is 660 watts. That is with a fully loaded computer.

Asus P6T Deluxe V2
i7 920 @ 3.8G
12G ram at 7-7-7-20
3 HD's in Raid 0
DVD burner
2X EVGA 480 gtx in SLI
24" Samsung LCD (1920X1200)
6X 120mm fans

All running on an 1100 watt Corsair PS. You have to also remember that your 15 amp outlet will only put out so much power before you start blowing the circuit breaker like crazy.
May 13, 2010 12:09:14 AM

660W for 2?

Total build or just Graphics?

Do you own Furmark?
May 13, 2010 10:36:10 PM

That is for total system load.
May 13, 2010 10:51:14 PM

^ Yep.

Point?

So 4 would be at 1250W or more when OC'd
May 13, 2010 11:35:28 PM

I feel I should mention this because it would be really stupid if it ended-up being the point of failure of this build: electric circuitry.

A typical household circuit is 15A @ 120V (in NAM at least) thus a theoretical 1800W. However, the building code says a circuit should be loaded to more than 80% to avoid fire hazards, therefore you have 1440W left. Note that this is for the whole circuit, meaning if you have lamps, printers, speakers, LCD, it all counts toward that limit. Moreover, don't forget to factor-in the PSU efficiency. A PSU wattage gives the maximum amount it can provides to components, not the amount it can draw from the wall. To calculate the max it can draw, divide the wattage by the efficiency; for example a 1200W PSU @ 85% efficiency: 1200 ÷ 0.85 = 1411W.

Note that if the wiring is 12AWG, you could always get a 20A breaker to increase that limit.
May 13, 2010 11:41:28 PM

Yeh, I think we have a 20A breaker.

And we have several.

And I think at partail load that PSU is at like 90%.

(Not that 4 480s would be partial load!)
May 14, 2010 1:32:00 AM

I suppose you could always use a Y power cable between two outlets on different circuits.

I have it but don't need it. I have an inline meter to tell me what it is using right out of the UPS.

Uh, the PSU draws 10%-40% (depending on quality) more than it needs.

Lets say I have a 80% PSU

If my build uses 1kw, the PSU will draw about 1.2kw from the wall.

I'm gonna sig this, thsi si the 19th time ive had to explai it on these fourms.

Enermax is not a reliable product? Where do you get your info from? You know little of PSU's if you think Enermax is anything but top manufacturer. They are every bit as good as the Antecs, Corsairs, PCP&C, Seasonic, etc.

I'M still stunned that Aktariel would say Enermax isn't a top PSU. And I'm a corsair guy and I am still stunned.

Enermax is on par with Seasonic, but so is corsair. Most corsair models are seasonic built.

If you look at the graph in the link, you will see its peak power. It goes on to say it averaged 800-900 under load. And that is OCed cpu as well. So it can handle one more. Now why you would want to do quad sli is another question entirely.

You have a 1250 watt enermax. It will hold up just fine.

It like the size of a entire cube case~!

also like how it has to wall connectors (supposed to be on different circuits if on 15A breakers)
May 19, 2010 12:33:46 AM

So I think it could handle them If I left them at the stock and iddn't bring the CPU near 1.4v,
