p.s. The psu is the antec true power trio 650 watt
Your issue may be with amps and not watts. I'm assuming this is the TRIO 650 you have. If so, the specs are a multi 12v rail design with peak amperage of 19amps on each rail (amps are not shared between the different rails, if they are not used they are "wasted"). 650 watts is enough to run A LOT of hardware but the amps supplied to each component are sometimes inadequate. In the future, look for PSU's that run only one 12v rail as they are built better and can deliver the right amperage where its necessary. Good luck!
