My specs are:
Intel Core i5 650
4GB 1333Mhz Ram, soon to be upgraded to 8GB 1600mhz
NVidia GeForce GTX 750 TI OC 2GB
The PSU is a 430w Semi-Modular Corsair : http://www.amazon.co.uk/gp/product/B00ALYP208/ref=noref...
Thanks!

Yes, it should be enough.

No. That card will eat up 300 watts under load. Personally I would get a 750w PSU.

What? That card will eat up maybe 60-70w.

To the OP, yes, that PSU should run that setup just fine.

For a system using a single GeForce GTX 750 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater.

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.

Corsair CX Series Modular CX430M (SKU# 75-002016 / CP-9020058)
• OEM: CWT (Channel Well Technology)
• maximum combined +12 Volt continuous current rating of 32 Amps
• one (6+2)-pin PCI Express supplementary power connectors
• Haswell Compatible: No
• 80 PLUS BRONZE Efficiency Certification
• 3 Year Limited Warranty

It's way more than sufficient.

You don't seem to know the difference between graphics card power consumption and system power consumption.

NVIDIA even states that the Reference Design GeForce GTX 750 Ti card is a 60 Watt card.

That's system load. The computer is using 300w with that video card under load, not just the video card.

While it is enough I believe and it is my opinion that its pushing it. Furthermore the PSU is the most vital component of your setup. Why put a cheap $20 after rebate psu in a nice machine? Again, just my opinion.

In that test they are using bare minimum, for cooling fans and a single ssd.

The OP's system is going to be drawing less than 200 Watts including the GeForce GTX 750 Ti OC so that isn't anywhere close to stressing a Corsair CX430M PSU.

No need to be harsh on somebody who's learning, and of course its powerful enough.

Thanks everyone, I've ordered the PSU, and to Proteus31, Corsair is not a cheap PSU brand. It is a well respected, quality brand.
