Just upgraded my gpu. Do I need to upgrade my cpu and psu?

Post by dammets89 » Thu Sep 25, 2014 5:28 pm

So I've been using a gtx 660 superclocked, and i just bought a 780. However im worried that i may need to upgrade my cpu and my power supply to handle the 780.

My cpu is an i5-3470 3.2 ghz
and the power supply is a cx 500 watt

All I want to know is if it's absolutely necessary to upgrade the cpu and power supply. If it's not absolutely necessary, I'd rather not have to upgrade those. As long as my pc runs fine with the new added power of the 780.

your cpu should be alright, and 500 watts from a reputable maker should suffice the only time you usually need more then 500 is if your running 2 cards.....

Who is the maker of that psu?

I switched to a 750 watt corsair when I upgraded to a 760, always nice to have a bit of extra power just in case. So, yes I recommend getting a better psu.

Well, 500 watt should be fine for it though... anything over 600 from what ive seen isnt needed unless your SLIing....

Safe as a house with your CPU.

Corsair PSUs are outstanding, and single rail the power, so you *shouldn't* have any issues I don't believe, but I personally would use a little more juice. I like 750s so I have a lot of overhead to work with. To be sure though, check the spec on your new GPU and see what amperage it asks on the 12 Volt rail. Compare with the spec sticker on your PSU. If the PSU has a bigger number on its 12V output than the GPU says it needs, you should be fine. If you're not sure how to do that, link your precise GPU and PSU here, and we can verify!

Ok, you're going to want to upgrade your PSU a bit to cover that. While it probably will run the card alright, it's technically under the specification and you don't want that by any means.

Card requires 42A on the 12V rail, recommending 600 watt minimum. The PSU you have is 38A on the 12V rail, 500 watts. Upgrading to a CX 600 would just cover you with 46A on the 12V, while a CX750 would be nice and safe with 62A. Incidentally, the CX750 can currently be had for $70 (enter the promo code!) with a $20 MIR to knock it down to $50 - a great price.
