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. | ||

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. | ||

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. | ||

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. | ||

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. | ||

+ 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. | ||
