I've planed to upgrade my PC with i7-4790 + GTX970 (Not going to OC any of them).
But i'm not sure that my 10 years old PSU 650W - 2*(12V*18A) will be able to power the upgraded PC well, according to my mates said this PSU is suck. I quite worried that it might not feed power to the system enough because it has only 18amp compare to new PSU that has 30amp+. How do you guys think, will it be fine with the upgrade?
Check the PSU that I mentioned : http://www.newegg.com/Product/Product.aspx?Item=N82E16817171014&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=6146836&SID=ib5czu2obf000a1700053
It's not a quality PSU. I strongly recommend a new one. Consider any of the following:PCPartPicker part list

The GTX 970 requires a quality 500W PSU that can deliver 28Amps or more on its +12V rail. The XFX 550W is a quality PSU that can deliver 45Amps on its +12V rail, which is more than enough to power your entire rig.
