hey guys i got my mobo today and ram 2133, and i was instaling all things and when i saw that on top of board the board atx power connector 12v 8 pin and my power supply also got 8 pin, and i'm bulding a high end machine this time with na H100 + i5 3570k and 8GB 2133Mhz Dual chanel and this z77 Extreme 4 and an GTX 680 TOP from asus, and i just was a bit confused by if i have to plug all 8pin in the atx power connector ? I will do OC so i think it will help for more power juce to get more performance from OC, dno if this have to do with it but i wold like to have an oppinion from you guys from my best friends for TPU !! Thanks guys ! My first option was z77 Extreme 4 + i7 2700k but i was confused and i did say ma self ok, way i wold go for an old chip ? and it was a bit cheapest but i did choice the i5 ivy 3570k and its native pci-e 3.0 , less power angry and also got new 22nm processor, and yha a price is like 250€ but still it will be a brand new machine 3d generation cpu and pci-e dno is just my opinion and i know that this ivy have a good OC potential. help me with that thing of atx power guys 8pin or 4 pin and tell me what you think on the rig ? is good for what ever i will do since gaming and working in SolidWorks and 3D Max Studio and AutoCad ? will this i5 performe nice ?
