I am getting a EVGA GTX 560ti graphics card and only have a generic 460w psu will this still be able to run the card properly. If not any suggestion on an affordable psu that will run the card well?

 

PC specs

i7 2600 3.4ghz

2tb hd

8gb ram

PSU 460w

Blu ray player

Integrated sound

the spec's of the rest of the computer would help alot.  but really, any high quality 550 to 650 watt PS would do for a single card build.  if you are looking at SLi or xfire, then you want a quality 750+ watt

"generally speaking" a powersupply that has passed the 80+ gold cert would be of a good quality (crappy units wouldn't bother to get that high of a cert )  there are exceptions, but those are just exceptions.

I wouldn't fancy running any kind of decent PC on a generic PSU unless you don't mind your components suddenly frying on you one day.

If budget is an issue then something like this would do the trick nicely http://www.overclockers.co.uk/showproduct.php?prodid=CA-118-AN

No, no, no.  The only difference between the various 80 PLUS certification levels is the energy efficiency.  Something that barely stays within ATX specifications on ripple on every single rail at room temperature, and goes way outside of specifications under more realistic temperatures, is a piece of junk, but could get 80 PLUS Platinum certification if its energy efficiency is high enough.

I wouldn't trust a "generic" power supply of any wattage to power a nettop (though it would probably work fine for a nettop), let alone a Core i7 and a nice video card.  If you don't replace the power supply, you'll likely be looking at dead hardware in short order--and not necessarily only the old power supply.

There are five 460 W power supplies on New Egg.  The Seasonic fanless one is about as far from a generic power supply as you can get--and also expensive enough that there's no way that you'd get it accidentally.  The other four are probably junk.

If in the US, I'd try one of these:

Those are both actually made by Seasonic, though they are different platforms.

I could almost cry at the price you guys get that Corsair in the US Quizz, it's £69.98 or $111.73 here. Prices have ramped up something silly for most components here in the UK over the past couple of years in comparison, a few years back they were pertty much on par and now it seems RAM and the occasional GPU is all that is.

460W seems kinds small even if it would be a good PSU.

And crap PSU have one more bad feature besides not being able to deliver power: they use more power than a good PSU because they are always running on full power while a good PSU only uses what you need at the moment.

This is one of the best PSUs money can buy, Corsair are the best company on PSUs and this is their best 650W PSU. Sure, $120 is somewhat expensive but the best cost a bit.

Nonsense.  If you were to ask Corsair what their best 650 W power supply is, they'd point you to this one:

Also, power supplies don't use their full power the whole time.  Low efficiency power supplies do waste power, but not 460 W at idle.

Thanks for all the answers guys. I will keep your advice in mind.
