Is 450w enough for this build?

[SirLoungelot]

Been trying to figure out a definite answer, but haven't really found anything. This is my first CPU build so I'm really trying to get it right. Here's the build:

Processor: Intel Core i5-4690K Processor - Quad Core, 3.5GHz
MOBO: MSI Z87-G41 PC Mate LGA 1150 Intel Z87
SSD: SanDisk Ultra II 240GB
HDD: WD Blue 1 TB Desktop Hard Drive 3.5" - Sata 6 Gb/s, 7200RPM
Memory: HyperX Fury Series 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Optical: ASUS DVD-Writer Black SATA Model DRW-24F1ST
Video: EVGA 02G-P4-3753-KR G-SYNC Support GeForce GTX 750 Ti Superclocked 2GB 128-Bit GDDR5

Any help would be greatly appreciated, thanks!!

for just running that PC it is OK but if it for OCing the answer is NO !
get 600W PSU with 80+ Gold will be amazing for the future

If you ever plan on upgrading to a bigger GPU later on I would recommend getting a bigger PSU. If you already have a GPU in mind which you plan on upgrading to later check its minimum requirements and get a PSU now that beats that by about 100 watts.

For a system using a single EVGA GeForce GTX 750 Ti Superclocked [02G-P4-3753-KR] graphics card a minimum of a 300 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 21 Amps or greater and that has at least one 75 Watt 6-pin PCI Express supplementary power connector is recommended. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.
