Hey guys, its been a while since i've been here but it looks as though it is time for an upgrade on my pc. I'm not looking to start fresh, just interested in 3 main components for now and am open to alernative choices as well as advice. Looking to upgrade my Motherboard, Ram, and Cpu but do have some questions in mind regarding psu usage on the new cpu and also compatability with my old gpu to the forthcoming mobo.

1st choice:
Core i7 Quad 2.66Ghz w/ HT 130W http://www.newegg.com/Product/Product.aspx?Item=N82E16819115202
Gigabyte Mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813128375
OCZ 3 x 2gb(6gb) http://www.newegg.com/Product/Product.aspx?Item=N82E16820227365

Im currently running a 520W OCZ psu (+12v@33a) so im hoping the 130W cpu wont drain too much power. Will however upgrade my psu as soon as I decide which gpu to get plus some more $$.


2nd choice
Core i5 Quad 2.66Ghz 95W http://www.newegg.com/Product/Product.aspx?Item=N82E16819115215
Asus mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813131621
Same OCZ ram as above

Lastlly, I want to know if my current gpu, evga 320mb 8800gts pci-e 16x, will run with the new pci-e 2.0/2.1

Thanks in advance.

hah, im leaning towards that side, i just dont want my psu to die after i get the 130W cpu :(

Your 8800 will run fine.

I would heavily research your PSU though. That's one item you absolutely do not want to fry - it could potentially damage any other component attached to it. I've seen 650W recommended for set ups like yours.

just my .02 - good luck with the new rig. :)

nice proc, but make yourself a favor a get it from Microcenter.com. They are the cheapest for those.

Either will be awesome, if you're going to spend the money you might as well go for the first one, but you should get a good 650W PSU or better to go with that system. That'll run any GPU out there as long as you aren't going SLI\Crossfire with high end cards.

I'd recommend a Corsair 650W.

wow, great deal on the i7. Im going to try and get it this saturday because its store pickup only :(

And im assuming this is the 650W PSU that CaptNKILL mentioned.. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005

My setup isn't so different from what you're after-

i7 920
Intel DX58SO mobo
4GB DDR3 1600
2x 8800GTX

And I'm using a 850watt silverstone psu I bought... can't remember when. :p It was some years ago- think I bought it shortly after the 8800s came out- so near 4 years ago? It's quad rail, 18A per rail- and running strong. Don't oc anything though.

I trust OCZ, but prefer Silverstone, SeaSonic or PCP&C more. If you can get a 650watt PSU from either of those you should be set- just be certain whatever PSU you get that it is not a dual rail PSU. :)

whats the main difference between single/double/quad rails, and you're saying that i wont manage with a 650W single railed psu??

Single and quad is fine. Dual is a no go and tri, well, they're rare for a reason. :lol:

"rail" refers to your +12v line, and we're concerned with the amps available on that line.

In a single "rail" psu, whatever amps it lists for the +12v rail is available for each and every component that may need it.

In a dual rail PSU, the amps on +12v 1 (the first rail) are dedicated to the CPU and CPU a lone. This is *always* over kill as the cpu will never use up that full amount, so those amps go unused, indefinitely. The amps on the +12v 2 (second rail) is what is available to the rest of your components, which is always insufficient when discussing higher end gaming cards (this includes the 8800s). The PSU will not be able to provide enough amps for the GPU under taxing situations.

A tri-rail PSU is better, as the second and third rails are open for your entire system, which means more power available for the GPU. However these PSU are harder to come by.

A quad rail PSU has four +12v lines. As with the dual and tri-rail PSU the first rail is dedicated to the CPU and those amps on that rail will for the most part go unused. However, you have three other +12v lines which offer sufficient power for most any high end configuration (save for tri/quad SLi and CrossFire).

The benefits of having a tri or even a quad rail PSU is that you can devote nearly an entire rail to just the GPU. Or in my case, one rail will be dedicated to one GPU and another rail dedicated to the second GPU (in my setup, rails 3 and 4), another rail dedicated to the CPU (in my setup and any multi-rail PSU, this is the first 12v rail), and the last remaining rail is devoted to the remaining components in my rig.

This ensure that each component, especially the power hungry ones, will never be starved of power (of course, assuming your PSU is capable of supply enough wattage as well).

Hope this makes sense. :o

Single rail is the best, three or four is good, but two can be bad.

It has to do with the way that the voltages are split amongst the different power connections coming from the PSU. A dual 12v rail unit may not allow you to feed a graphics card with enough juice because one rail is limited to the motherboard\CPU leaving only one 12v rail for other components. I don't know if they all work this way, but its a problem people have been talking about for 5-6 years now.

Multi-rail (3-4 12v rails) PSUs are flexible enough that you shouldn't have any problems unless you wire a GPU up in a strange way and it consumes a ton of power.

Single rail is arguably the best though since all components feed from a single 12v source, so that it doesn't matter how you wire your setup, you'll always be able to take full advantage of your PSU. IMO, as long as your setup is working without problems then none of this really matters, but you're less likely to have problems with a single powerful 12v rail than with 2 or more.

My OCZ 700W GameXStream is several years old now but it handles everything I throw at it with ease. It has 4 12v rails with 18A each. It doesn't have any 8-pin connectors though so if I get a high end GPU that needs one I'll need to use an adapter of some sort.

EDIT: Damn you Redeemed. :p

I've got a dual 12v rail (2 x 40w) PSU and it is a bit confusing working out what it powered by which rail. If I were going tri-sli/xfire then I would be worried about it, but tbh a 40w single rail is probably enough to power most dual GPU rigs and I'd just use the other rail to power the third card.

The only thing to consider is which rail powers the mobo, so it would probably be best to use that one to power only one GPU and leave the other one just for the two GPU's. Luckily I don't need to worry about that, but as you can see, it's a bit of a headache... a single rail is a definite win for simplicity and fool proof full efficiency.

What is the main difference between PCI express 1x/4x/8x/16x.. I mean im looking at this eVGA x58 and it has 1 pci express 16x slot, 2 8x slots and a 4x. In order to do a 3 way SLi do I have to have 1 vid card in the 16x slot and the 2 other ones in the 8x slots with a bridge??

Thnx with the psu advice, going to find a single rail 600W+ ocz or corsair psu :D

You either mean 40 amps or 400 watts... not sure which. :p

No way you mean 40 watts... even our CPUs consume far more than that now days. :lol:

Also- in your case due to the insanely high wattage and naturally just as high amps available in general you're okay. But not everybody can dump $175 - $250 for a PSU such as yours.

Single rail PSUs are by far the best solution, however dual rails are quite arguably the worst (no offense) simply cause your first rail is entirely dedicated to the CPU (I have read of some PSUs that seem to avoid this some how but they are incredibly rare and pricey, and their reliability I'd call into question) which only leaves the second rail for everything else... including your graphics card.

My hunch is that if you added a 5970 or GTX295... or even tried to run high-end SLi such as dual GTX285s or high end CrossFire with dual 5870s you'd probably run into stability issues cause that second rail wont be able to supply enough amps to your cards as well as the rest of your components.

For a single card, however, you are most definitely fine. :lol:

1st choice definitly, I really dislike asus, because the boards I did have, were super finicky and my gigabyte board right now is freakin solid as a rock made out of wolverines adamantium.

Oh and i7 > i5 even though they are both good proc's, the truth remains.

This difference in the PCI- e slots is bandwidth- higher the multiplier the greater the bandwidth.

For tri-SLi you'd have to put your cards in the x16 and two x8 slots.

Picked up my core i7 920 at micro center for $199 :D I was wondering why are they selling it so cheap compared to newegg?? Is it a different cpu or something?? But nontheless excited to try it out once I order the remaining parts.

Finally ordered the remaining parts off of newegg. After some thought I ended up getting, the EVGA LGA 1366 Intel X58 ATX X58 SLI LE Intel Motherboard, 6 gigs of OCZ ram, and a Corsair 650W psu. Cant wait to build it once the parts come in!!

So I finally finished building my new rig today, got pretty upset when I realized the new CD drives no longer have the "IDE" input.. so I had to run out to best buy and pick out a new drive.. Overall pretty happy with the new setup, too early to tell if there are any problems with any of the components.

Thanks again everyone for the info and advice.
