no, that GPU and generally high end GPU's want a 500w PSU. Tell us the exact brand and model of the PSU so we can see the 12v rail
The PSU is a stock psu built in with a Raidmax Super Hurricane case.
Those PSU's are the ones made by Sun Pro Electronics. The +12V current rating somewhere between 14 and 21 Amps depending on how long ago you bought your case. Corsair had a video, that they made, using this Raidmax PSU model as an example of a cheap exploding PSU and why they should be avoided.
For a
system using a
single GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater
system power supply that has
a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least
two 6-pin PCI Express supplementary power connectors. Some of the non-Reference Design GeForce GTX 760 cards have a single 8-pin or two 8-pin or one 6-pin and one 8-pin PCI Express supplementary power connectors.
Your 450 Watt Raidmax PSU can't do it since it's so grossly under powered and doesn't have any PCI-E power connectors.
