How much power supply should I have for a
EVGA 01G-P4-3650-KR GeForce GTX 650 Ti 1GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP Ready Video Card

Would 450 be enough? or should I go for a higher one?

Would that one be good enough?


You didn't list any other specs, but assuming 2 hdd, 1 opt dr, 2 case fans,
& mainline CPU, then yes a cx430 will run that 650ti.

I'm using the 1TB HDD from my older computer and same goes for the dvd burner

Some one told me it would heat up and not work decently. But with those 5 fans in the case and having an AC in my room, I don't know, I'm doubting.

OMG, he really doesn't need to.

If he's thinking about a GTX650 Ti or GTX650 Ti OC then his total power draw will be under 300 watts anyway.

A 400watt PSU will be ample, so long as that isn't its peak output figure.

Thank you man! I'm not that new to these kind of things, but I can never know for sure. Thank you again bro :)

No thanks necessary --- appreciated all the same.
Many years ago, and almost as many forum restructures, Toms Hardware got me up and running. (Before 500MHz CPUs, and as far back as 25MHz ones).

People here tend to over estimate the power supply, which there is nothing wrong with as it leaves headroom.
Todays PSUs are 80% efficient (minimum) from idle to peak, and often 90% efficient at 71% load.

One simple trick is to base your consumption on the model of GPU higher than you're aiming for:


From this article: http://www.tomshardware.com/reviews/geforce-gtx-670-tes...

Then go the greater of at least 50 watts higher, or +25% higher in PSU draw.

*** Bear in mind the above chart is just the video card, a PC may draw up to another 187 watts. ***

For a system using a single GeForce GTX 650 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater power supply that has a combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C-50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the 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 you are trying to achieve.

The Corsair Builder Series CX430 (CP-9020046-WW), with its combined +12 Volt continuous current rating of 32 Amps and with one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 650 Ti.

Man I wish I could select 2 best answers here. Thank you both Scott and Ko, you guys have relieved a burden from my shoulders and man does it feel good.

There's no way of writing reviews or rating other fellow members is there?

Anyways, Thank you both a lot!!
