gtx 660 wattage query

[ArunKumar]

Hello Everyone,
I am planning to get a GTX 660 gaming card and i am not sure if my current configuration can give all the necessary power to the card.I have a 500 w PSU to support my build.

Here are my full specs of my build
Motherboard: Asus Maximus V1 Hero Motherboard
CPU: Intel 3.4 GHz LGA1150 4670K
RAM: Corsair Vengeance DDR3 4 GB x 2
HDD: WD Blue WD10EZEX 1 TB Internal Hard Drive
SDD: Samsung 840 Series 120 GB SSD Internal Hard Drive
PSU: iball Marathon 500w
CASE: Cooler Master Enforcer Mid Tower Cabinet
CD/DVD drive:HP DVD1260i-UH07D DVD Burner Internal Optical Drive
Keyboard and mouse: Razer blackwidow 2013 & Razer deathadder 2013

Can the current PSU give all the necessary power to the GTX 660?Or should i get a PSU with a higher wattage?

That should be enough to power everything, but your PSU will be working pretty hard if you start putting some pressure on the CPU or GPU.

Is budget a big concern here? I think that setup will work, but it's probably not a bad idea to spend a little bit more money to get a PSU with a bit bit more wattage. It won't be working as hard, and who knows--maybe a year from now you'll decide you want another graphics card, and if you do, you'll have to buy a new PSU too. 😉

i see,thank you for your reply jamRw00 🙂
yes i am planning to get another graphics card later and run them both in SLI.Keeping this in mind would a 600-650 w PSU suffice?

for sli go whit 850w. to be on the safe side.
they recomend from 500w as minimum on those card and some as 550w.
and that whit just one card in system.

The power supply is the most important part of any system. It isn't one of the components that you'd want to cheap out on. If you're looking for a budget but high quality power supply, I can highly recommend the Seasonic S12G 750W. Now if you want to invest in a eve higher end one, you can take a look at the Seasonic Platinum-760w.

Think of a PSU as foundation. Now a weaker foundation will hold the building right up until it falls down.

Thanks for all your answers guys,But my budget is about $120 USD max.After a lot of research and looking around I resided I am going for the
Corsair CMPSU-750TXV2UK 750 Watts PSU which just fits the budget.
