Can my 300w power supply run a GTX650?

[ZeFalkon]

For quite a while, I have been running a GT630, which was fine for most games. When I first assembled by computer, I tried to be cost-effective, which made me buy a 300w power supply. Now, I decide that I should go get a GTX 650 so I can play more modern games effectively. I first realized that the GTX 650 needed a 6-pin adapter, but I found out that the power supply did in fact have a 6-pin. I was ready to buy it, before I realized that I better check how much watts my power supply is. To my dismay, it was 300 watts (400w is minimum for GTX650 according to Nvidia). I was wondering, would it be alright to run a GTX 650 on a 300 watt power supply that has a 6-pin?

Easy graphics card upgrades using only motherboard power
Attain better graphics without the messy cables or buying a bigger power supply. GTX650-E-1GD5 gets all its power directly from the PCI Express slot, leading to a neat yet capable graphics configuration.

Same thing (no 6 pin needed): http://www.newegg.com/Product/Product.aspx?Item=N82E16814487024

if it is a generic piece of garbage, try it out, the worst that can happen is the psu will crap out, if it is name brand (Antec, Corsair, Seasonic, etc) it should work fine. Also, i like this design: http://www.newegg.com/Product/Product.aspx?Item=N82E16814121710

If you ever need a PhysX chip, this one does not use a 6-pin, it uses power straight from the mobo, so if you get, say a GTX 860 (complete speculation) down the road, you only need a psu with 2x 6-pins (or however many your future chip will need) and enough power (probably around 500-550w) to run both cards.

Your speculation was overlooked Lee! 😉
