Im about to purchase a bunch of PC parts, and i still can't get my head around the correct supply, these are the parts i have picked and they will not be subject to change (i know the urge of ppl suggesting better things, but im limited to these parts due to money and a small selection). Any they are: 1. Intel 3.3 GHz - i5-2500 6M/LGA1155 - http://ark.intel.com/products/52209/Intel-...Cache-3_30-GHz) 2. Patriot PGD34G1600ELK Gamer Division 2Series 4GB (2GBx2) PC3-12800 (1600MHz) KIT- http://patriotmemory.com/products/detailp....1050&type=1 3. Intel DP67BG w/Sound+SATA+1GB - http://www.intel.com/products/desktop/moth...BG-overview.htm 4. ThermalTake VM20001W2Z Armor A60 case - http://www.thermaltakeusa.com/Product.aspx...325&ID=1968 (with all related fans included) 5. 1TB WD1002FAEX 7200RPM S-ATAII 64MB Black Edition - http://www.wdc.com/en/products/products.aspx?id=100 6. Asus ENGTX560 Ti DCII TOP/2DI/1GD5 GeForce GTX 560Ti 1GB DDR5 http://www.asus.com/Graphics_Cards/NVIDIA_...Ti_DCII2DI1GD5/ (NOTE: The link is the non-top one, the top one is clocked to 900mhz i can't find the the spec link to it, but that is the only diff between the top and the non-top) From my personal calculations, i picked out the 650w toughpower grand thermaltake - it should be enough, but im a novice with PSU's; i don't know what is the best brand for i heard thermaltake wasnt the best so i started having doubts and started looking around again. Also im highly limited to the power supplies shown here : http://pcandparts.com/must.htm (scroll down and its to the left) - its the only local place with good pc parts and at competitive prices. So basically if the required PSU can be one from there it will make my life much easier.
