It's about the most accurate PSU calculator around. | ||

In other words, 430w is enough. If it's a good 430w, obviously. | ||

What is your budget? $800 or $975. The difference is the ~$175 I have of my own (this computer will be a gift to me). I'd sort of like to spend it on a new keyboard (Razer Blackwidow Ultimate) and mouse pad (Razer goliathus, yes I am a Razer fanboy), but if it means a big difference in performance I am more than happy to spend it on components. What is your resolution? 1920x1080, brand spankin' new monitor that's about a month or two old and is very sexy. What are you using it for? Mostly gaming, SC2/WoW/LoL/TF2/any other games my friends recommend and that I can afford. Also web surfing of course, but I don't plan on doing video editing or the like. What is your upgrade cycle? 2+ years certainly. When do you plan on building it? I will be ordering the parts Sunday or Monday once I (finally) get out of school. Do you plan on overclocking? I heard from a friend that overclocking voids the warranty, in which case I don't think that's a great idea, but if someone wants to prove me wrong that's fine too. I like the idea of overclocking but I'm not sure the risk of voiding the warranty is worth the rewards. Do you need an Operating System? Yes, unfortunately. Coming from a mac-obsessed family means no one has a Windows OS to give me. Do you plan to add a second GPU for SLI or Crossfire? Maybe? I don't really plan on it unless I come into a large sum of money. Where are you buying your parts from? Newegg/Amazon. I have amazon prime so that's a plus, but the free 2-day shipping deal from Newegg seems legit so if it is I guess that voids the benefits of Amazon. Thanks very much guys! I hate to be a bother so let me know if I am =) | ||

Yeah I suppose they're pricey, but from the reviews I see the Blackwidow is worth it. Plus I already have a Abyssus and Moray+'s, as well as a tarantula. Maybe I'll just stick with the tarantula for now. | ||

Number of 12v rails isn't important. The difference between single and multiple 12v rail doesn't matter for your type of configuration. The CX600 only provides 6a more than a XFX 450w or in other words, 72w. If you're pulling 504w from the wall (AC), a 85% efficient power supply would mean 425w DC. A single graphics card configuration is never going to pull this much power (excluding dual gpu on single PCB cards and those crazy configurations). A core i7 2600k pulls less than 100w under full load and all modern single GPU cards pull less than 200w (excluding GTX 570, GTX 580 which both pull less than 300w). The calculator didn't give you the figure of what your components would be at under load, it gave you a recommended power supply wattage. You're severely overestimating the power needed for your configuration. Here's a visual explaination: + Show Spoiler + | ||

If your power supply is running around 90% at a full stress test load, then in a game it may be at 60% or so, where efficiency is better (by like 1-3%, so who really cares?). Power supplies have worse efficiency at 20%, and it gets much worse the lower you go. Because of efficiency at idle loads, you'll be running higher PSU efficiency if your full load power draw is close to capacity, unless you're really running loads that highall the time. But if you care about efficiency, why not just get a more efficient power supply? A few percentage points of efficiency on your power supply is insignificant compared to the rest of your power bill, unless you're pretty spartan on energy usage otherwise, and run your computer to high loads 24/7. If you want to get a better power supply, get a better power supply with more reliable components and more accurate and stable outputs, not something that may or may not have better efficiency at the loads you're running. btw, you do realize that 0.8 * 1.2 is not 1.0? | ||

CPU + Mobo: i5-2500k and BioStar Z68 mobo http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.658273 $315 RAM: 4GB DDR3-1600 1.5V RAM http://www.newegg.com/Product/Product.aspx?Item=N82E16820231313 $34 (use code EMCKDKC22) Hard Drive: Western Digital Caviar Blue 1TB 7200rpm http://www.newegg.com/Product/Product.aspx?Item=N82E16822136767 $50 (use code EMCKDKC74) Power Supply: Corsair 430W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 $20 (use code EMCKDKC32) Optical Drive: LG DVD RW http://www.newegg.com/Product/Product.aspx?Item=N82E16827136238 $20 --- That's the core of your computer for $480 before rebates, $460 after. Now, graphics card. If you just want to run SC2 at max, the 5770 is the cheapest card that will do what you want and you can get it for around $100. YOu can upgrade to a GTX 560 if you want which will crush almost all games on the market today GTX 460 - http://www.newegg.com/Product/Product.aspx?Item=N82E16814125383 for $187 after rebates That's $677 total before rebates, $647 after. ~~~ Now, you'll need a case. I have no recommendations there, since what I think is pretty may or may not be what you think is pretty. Let's just assume $80 for the case. That's $757 before rebates then, $727 after. ~~~ which leaves you with your OS: If you still have access to a .edu address, you can get Windows 7 Pro for $30 http://www.fatwallet.com/forums/hot-deals/1087206/ which would put your total at $787 before rebates, $757 after. If you don't have access to a .edu address, then uh...F. I think Windows 7 costs like $100 or something like that? ~~~ That would put your total at $857 before rebates, $827 after. Like I said earlier, you can downgrade your GPU and save about $100 if your $800 budget was hard and fast Ta da, computer! ~~~ Note: If you're near a microcenter, the i5-2500k is only $180 before taxes, ~$200 after, which would save you about $30. You might even be able to pick up one of their CPU mobo combos, though that one from newegg is pretty nice. | ||

But to be honest, you prob won't have ot since the i5-2500k is so fast at stock anyway. This computer should last you several years, if not more. | ||

Basically, if you're not comfortable with the 430w Corsair unit, go with the Neo Eco deal linked in the same post instead, and be 100% sure you have more PSU than you need. I'm pretty sure the Corsair will be fine though. skyR or Myrm could tell you for certain. | ||

The only problem with the Neo Eco (and maybe most power supplies?) is that it doesn't come with a power cable. This isn't a problem for most people since they upgrade their computers, but I only have a laptop right now and do not wish to donate it's power cord :p. | ||
