|"sorry forgot about psu. 630 watt"|
Wattage isn't as important as quality of the PSU & the amperage specs, plus you need to have all the required plugs. A decent 630W unit costs about $75 & for your system, you need one with an 8-pin ATX12V/EPS12V plug...that connection is what powers the CPU. Is your PSU compatible the Core i5/i7?

"no i didnt benchtest before building"
Gut the case & benchtest your hardware.
