Hi! I had a Coolermaster Elite with ASUS Radeon HD 4670. I upgraded to Coolermaster HAF 932 with those huge 3x 230mm fans and 1x 220mm fan and ATI Radeon HD 4890. I used a powercool 650w PSU and it just can't support the extra power required by the 4890 GFX card and those massive fans on the HAF 932 case, the computer hyst keeps on restarting. I have ordered Hiper 680w Type R-II HPU-5K680 power supply unit and I am worried that it won't be enough. Will it be enough? and is it just that my current psu is horsepoo?
