Power requirements of Nehalem motherboards

If you compare the AMD and Intel at this moment the difference is not too big, so there should not be big difference between Nehalem and Core, If anything does not go wrong.
I predict that Nehalem platform needs less power than Core platfors as total, because of the lack of north bridge, but on the other hand I have newer win in lottery...
All in all at this moment the energy effiency is very popular concept in CPU industry, so I don't that intel would like to introduce new type of prosessor that is power hungry, exspecially when they are targetin mainly the server sector at first with Nahalem.

No new power platform (to my knowledge) has been ratified recently. It should adhere to either the ATX 2.3 spec (4-pin 12V) or EPS (8-pin 12V). My bet is the ATX form with optional 8-pin connector (like almost all P35 or X38/48 boards now).

Edit: Short answer - should stay the same.

KyleSTL with the info again! Thanks very much.

Basically I need to make sure that I buy a PSU with EPS / ATX 2.3 if I want it to last into the next build.

Can someone enlighten me as to what the difference between V2.2 and V2.3 is?

Unfortunately I think that means forking out for an Enermax Modu+ (v2.3) rather than a Corsair TX/HX (although it may have EPS).

Nice find. Did any one notice the Skull near the PCI slot? Could this turn in to another Skulltrail not many can buy?

Even if the power connectors are different manufactures will make converters.

Ok, so what we are saying is that:

The new motherboard will have 24pin (MB) and 8pin (CPU) power connectors and that the Enermax and Corsair PSU's come with both of those, so whichever one I choose I will be able to use the power supply into the next motherboard designs.

Enermax also suggest that graphics cards might move to 10/12 pin power designs or is this just a marketing ploy? Any comments?

Thanks again

Thanks Zorg and KyleSTL. I'll look out for adapters (I won't be the only one) when the need occurs.

I agree with both Zorg and Kad. However I'm in need of a new psu and thought that I may as well try and buy one that will last into the next motherboard design for when I rebuild.

Thanks Zorg, unfortunately I'm in the UK (so once you add shipping....!!)

I am thinking about a Corsair HX620 (~£80). I'm struggling to work out if it comes with 2x 8pin PCIe. Although I'm torn because if I want to SLI in my next build, currently I only have one PCIe, I might be better off with the TX750 (~£82) but it is louder and not modular. I'm not entirely sure if it would take 2 9800GTX's (for example) anyway with 60A on 12V.

I was also thinking about an Enermax 625, very quiet, but that is quite a lot more at ~£105. It does come with 4x 8pin PCIe though, but it might not handle 2 9800GTX's because it has 50A max on the 12V.

Comments?

Edit: I have been using silent pc review to gauge noise level. I have to have my PC in my room at uni and don't really want a huge roar everytime I have it on...

Thanks Zorg. I used the calculator, it suggests:

450W for 9800GTX in SLI, 30A
470W for 9800GX2 in SLI - seems rather low. People have been suggesting you need 550W and 40A just for one of these things.

It looks like the Enermax 625 (50A) with 4x 8pins will do for 2x GTX's but not 2x GX2's. The TX750 (60A) will probably handle the same even though it has another 10A avaliable.

How do I find out what current these cards really need? That will basically solve this problem for me. NVidia are just suggesting about a 800 - 1000W which just seems excessive.

Thanks Zorg that is the sort of information I've been after!! Not this "you need 1kW+" from NVidia.

I'll try and decifer what it means in terms of my build after my exams this week! (The joy's of being a uni student!)
