Since I still cant create a thread I'll post my question here again:
How do multi rails work in PSU. For example. I have a PSU which has 4 +12v rails each with a max a of 18 and a total max of 40a.
Now the question is: could this PSU run a gtx570 which has a peak load of somewhere around 260W which is like 22A. Would it just use two of the 12v rails or would the PSU just shut down?
Hope someone can help me.

I hope that's not a realistic example cause that's a pretty shit PSU...
All modern (non-shit) power supplies have their rails split accordingly so you won't be overloading a rail with a single GTX 570 for it to shut down. Even though most power supplies specify multi-rail, they really only have a single rail. It's pretty complex so I wouldn't be concerning yourself about this.

Uh... that 18A split rail design was very popular back a few years ago. Many great PSUs (including the Corsair HX620) used a similar split rail design.
Relaxtakeiteasy: Since each rail has a max of 18A, you would want to use PCIe connectors from different rails, but the cables are not always labeled.

Usually the actual overcurrent protection trip points are significantly higher than what the rails are advertised at, by the way. e.g. 25A limit on a rail specified at 18A. Other times they're just lying and there aren't that many rails (no OCP, or at least not for the rails specified).
If a power supply has 480W on +12V and four +12V rails, it probably has PCIe power connectors on different rails (and on a different one than the CPU power connector).
edit: wait a sec it's a 550W unit with two 6+2-pin and one 6-pin so maybe it would have two of those on the same rail. I'm 99% sure there would be no problem though, at least if you're not pulling a hardcore overclock on the GTX 570.
edit2: and the Straight Power E8 is still the worst of the four power supplies you mentioned earlier btw, except in noise.

I know, I allready ordered the golden green. I saw it and I was just curious.

What do you think of this?, i don't want to play sc2 at highest quality but i want to play smooth, i have a pentium 4 by the way.I play on 1280x1024 but in the future i wanna play on 16 :D
New PC
260€~370$

So I may sound retarded asking this but if I am building a new PC would it be possible to use components from my current PC? I would have thought things like the hardrive would be reusable.
Also is there any way to transfer the operating system to a new PC.
A friend of a friend got me windows 7 professional for free and I don't think I can do without out it now. Obviously I don't really wanna pay +£150 to get it again.

Hard drives are reusable, and you can even keep all your data and stick the HDD into a new computer and with a little tweaking and checking compatibility between parts, you're golden.
And yes, you can do a "flipped" upgrade where you upgrade a lot of parts and keep one or two (as opposed to upgrading one or two and keeping the majority). It can also be viewed as upgrading a lot of parts.

If you are buying new PC hardware you can get an OEM copy of windows for about $99 aud. Otherwise all you need is Windows 7 Media (download it if you have too) and you current Windows CD Key (google a program called Belarc Advisor which can pull it from your current PC) and you can install that on your new rig.

Is there any way at all to make Windows 7 recognize my i5 2500k overclock? The Battle.net beta system updater does not recognize it either (yes I am looking at CPU speed not the model of my processor).

MY GPU temp keeps hitting around 78-79 C under stress. I have 2 stock case fans. One in the front (inflow) and one in the back (outflow). Should I get a side fan and another? Or would that not help that much?

No there isn't.

80C is fine.

My spanish is terrible, so I can't maximize value on that site, but you can stay (just) within budget and get a more powerful configuration (I'm assuming you already have a case, SATA harddrive, and DvD drive since you didn't put those parts in your original configuration).
For about 40 more euros you can get an i3 + 1155 motherboard. I don't know how the 1155 pentiums stack up against the Athlon II you linked, but the i3-2100 will definitely be more powerful for SC2.
I have no idea if the NOX Urano is a quality PSU or a random one, I couldn't find a good english review, so I calculated price with a Corsair CX430 V2, which is a known quality PSU (20 more Euros).
Since RAM speed means so little with Intels (I have no idea with AMD CPUS), you can get a single stick of 4GB ram for 22euros (or if you don't want to upgrade in the future, 2x2gb 1333 ram, that's a little faster than 1x4gb) or 2x4gb for 42 euros.
For some reason when I selected the same video card you did, it cost more. Maybe they changed prices? Or maybe you can pricematch on that site but I have no idea because of spanish deficiency?
In any case here's my not-expert, probably not as efficient as possible sample i3-2100 configuration. It should be more powerful than going for an AMD processor though:

Hey i am looking to spend around 1 grand for a gaming pc also just fast in general for the web. any adive? was looking to buy on ncix.com

@ iambiizzare I recommend filling out the full form at the beginning of the thread.

Eh, what the hell. You guys have been a great help the last couple of days, so I have a fairly general idea of what I want to do, but it wouldn't hurt to get some more feedback.
+ Show Spoiler [Questions] +What is your budget?
Up to $1000ish. Maybe a little over, but I won't complain if it's under.
What is your resolution?
1680 x 1050 But it's the maximum resolution on my current 4 year old monitor. I'd be more than happy to take some monitor recommendations as well, either included in the budget or outside of it.
What are you using it for?
Gaming mainly, but no encoding or anything along those lines. Don't know if this is really relevant, but I do like tabbing out while gaming and browsing the net and such... and I tend to be terrible at tab management, so it's not unusual for me to have 50-60 Chrome tabs open, with a game and WMP or something.
What is your upgrade cycle?
Probably 2+ years, but I'd probably upgrade key parts, if possible, as time went along before building a new PC completely.
When do you plan on building it?
Probably order all the parts within the next week or two.
Do you plan on overclocking?
I was thinking about it, but for this build I'm fine with keeping costs down and going with the i5-2400.
Do you need an Operating System?
Should be able to get a student copy for $30.
Do you plan to add a second GPU for SLI or Crossfire?
Nope.
CrossFire and SLI are powerful solutions that allow higher performance, but in order to utilize them, we have to choose motherboards and PSUs that can support the increased demands that Crossfire and SLI place on your components.
Where are you buying your parts from?
Newegg probably. I can utilize Fry's ads should they have anything good, but generally they're more expensive.
+ Show Spoiler [other info] + - Case wise I'm leaning towards the Lancool K-58/60. Though if you have a better recommendation, even if it's a bit pricier, I'd consider it. Better as in the important aspects anyway, and not necessarily aesthetics. I'd probably consider using whatever case I get in my next build, unless cases change drastically in the next two years, so I'd definitely like something that will last.
- Before I thought about building a new PC entirely, I upgraded my video card based off the recommendations for my resolution in the OP. I bought an EVGA GTX 460 1GB SE. I just bought it a few months ago, so I'd definitely consider using it until a new line of cards comes out, if you guys think it will do the job. However, having read some comments in this thread the last few days, it's apparently a terrible card... so I'll take recommendations either way.
- A SSD/storage drive is recommended, right? I'd be willing to include that in my budget.
And just out of curiosity, what are the benefit/disadvantages to a modular PSU, other than cabling? My current PSU is a Corsair 620 HX and I know it's modular.
On a completely unrelated note, a house across my street is on fire right now. Or rather, there's a ton of firemen/emergency services putting it out now.
Thanks for all your help, guys!

The final price is 303 of that build, so. do you think that build it's gonna be so much powerfull than the other? The thing is that i wanna update my current pc without spending too much cause i don't want a 1000€ pc, other thing is if will be able to update the micro, i don't know how long will last the 1155.
