Is a 250W PSU too small for a GTX 1060?

Loleliam · Aug 30, 2016

Right now I have a prebuilt desktop that runs on a 250W PSU, specs:
GPU: GTX 750ti
CPU: I5 6400
RAM: 8GB RAM
HDD: SATA-600 1TB
MOBO: Not sure but the chipset is an Intel H110 Express

I'm thinking of upgrading to an EVGA 1060 SC but I'm not sure what PSU I should get or if this one is enough which I doubt. The 1060 takes around 120W while my 750ti takes around 60W. On NVIDIAs website it says the minimum for the 750 ti is 300W and the 1060 is 400W.
Also I don't know what PSUs are for gaming or not. My friend keeps telling me I should go for a 700W psu but that seems a little overkill so what are your thoughts? What PSU should I get? I don't wanna spend too much on it, maybe somewhere around 50$.

really good rebate on this psu right now and it would be plenty for a locked cpu and a 1060. $50 before rebate of $20

not the best psu out there but good enough for your use. would easily run more gpu if you decide to move it to a new build later on. some better psu's below $50 but they are much lower powered.

Math Geek :

Actually an equal rebate on the CX450M. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139146

interesting that they are both the exact same price. for the same money i'd get the 500w one cause...well why not get 50w extra for same money

nice find though.

Math Geek :

Because the CX450M is semi-modular, a new design based on the RM series, and has a better rifle bearing fan that is also quieter than the CX500. And 2 years longer warranty. And should be more efficient with a system like his.

i missed the m part in my haste.

so leaves a couple nice options for the op. semi modular and 450w or non-modular and 500w. think the 450 might be the way to go then as semi modular is always a nice feature to have and as you noted a newer design as well.

If I buy the semi-modular one, do I have to buy any external cables?
Thanks

Math Geek · Aug 31, 2016

no it comes with all the needed cables. you just use the ones you need for the build and leave the rest in the box

pretty nice really as it cuts down on the clutter of extra cables tucked away here and there.

But if I also get an ASUS Z170 PRO GAMING, is the CX450M still enough?

Not much point in getting that board with the current CPU unless you plan to upgrade to a K series one in the future

I'm just afraid the GTX 1060 won't fit in my current mobo. The card can't get much bigger than the 750 ti or it will reach the RAM sticks.
