Hi,
I have couple of questions regarding the compatibility for the ATC-605 (http://www.futureshop.ca/en-CA/product/acer-acer-aspire-atc-605-desktop-pc-intel-core-i5-4440-1tb-hdd-8gb-ram-windows-8-atc-605-ef30/10269719.aspx?path=ea1c734d7f49bc0e4dfb5b44885ba4ecen02)
Thank you in advance. Please reply even if you may be able to answer any of them.
1. Possibility of upgrading Graphics Card with PSU of 600W or 750W. I have seen a related topic. However, according to Acer, the maximum PSU wattage is 300W. So, are common PSUs with higher wattage (such as 600/750W) compatible with this motherboard? Will it fit in this cabinet? What is the form-factor for this system? Will a higher wattage burn anything
?
2. Are all common DDR3-1600 /PC3-12800 RAM compatible with this board?
3. Is virtualization supported? I am asking because the Intel H81 Chipset coming with this does not support it, it seems? What is the significance of Intel® H81 Chipset (Intel® DH82H81 PCH)?
4. Warranty policy for upgrading the desktop system. I would like know if upgrading memory voids warranty? I am guessing upgrading graphics card or PSU voids warranty? I am asking since I bought the system only recently 
Thanks,
Jerry
