I'm thinking of upgrading a PC I got from my uncle

[magnus0036]

I recently got a PC from my uncle and I'm planning on upgrading the graphics card to Nvidia Geforce GTX 1060. I just wanted to ask if any of the other parts also need to be changed.

My specs are:
GPU: GeForce GTX 660 Ti
CPU: Intel Core i5-3570K CPU @ #.40GHz
RAM: 24 GB
Motherboard: MSI Z77A-G41
Power Supply: Seasonic S12II-520Bronze 520W

Thank you.

should be fine

A gtx 1060 will be fine in this system. 520W SeaSonic PSU (480 technically) is more than enough for that CPU+GPU.

Why do you say its 480 Technically? I own the Seasonic S12ii 520W PSU (magnus0036, I own it and contrary to reviews to me its silent, moderately high quality and reliable, I personally recommend the M12ii for a few USD more).

I'm interested in learning more, why would a superior brand advertise and sell the PSU as a 520W if it can only make 480W? Can you cite any sources, or explain in detail?

Thanks.

it's 520W
but it delivers 480W on the 12V rail (40A)

480W on 12V ok, but you need to add 5V, 3.3V as well to get to 520W - this is typical of every PSU rating, is it not?

Sorry for being ambiguous with that, i wasn't referring to it only being 480W as a whole Unit, the 12v Rail is what i was referring to which is what the GPU/CPU operate from.
Seasonic's site was my source. Look on the specifications page and at DC output .
Also you might want to read these:
12v Rails
Efficiency
Hope this helps somewhat .

You are correct, his question was on upgrading the GPU and i was just pointing out that adding a GPU that uses more power will not be too much for the 12v Rail.

 

[JQB45]

Thanks for the clarifications, it makes sense. Am I correct in that the PCIe provides 3.3V in addition to 12v?

No problem. And yes it provides 12v/3.3v and i also believe that a 3rd, optional, 3.3v Rail is sometimes used depending on the designer.

Pretty much everything in modern pcs uses 12v, hence why many PSUS that are "500w" can actually deliver 500w on the 12v rail.

delivering 500w on a single 12v rail is not a good idea and would be a bad design choice. pretty much every component doesn't use 12v Rail - Read up more on it. Also why would you slam 25A for example at a logic chip that can operate on a 5v rail? Seems illogical :/.

Well pretty much all good PSUs these days are single 12v rail systems.

Ok, what uses 3.3v and 5v from the PSU in a modern pc? AFAIK the vast majority uses the 12v and is converted down if need be, like the CPU for example, takes power from a 12v output from the PSU which is then converted down on the motherboard to what the CPU requires.

I know I am throwing off the conversation a bit. But I think we need to switch to a 20/24V system. No 3.3V or 5.0V. Its very efficient and it would make power supplies less complex.

I wasn't talking about single 12v rail over multiple 12v rails; what i meant was sending power for everything down the 12v rail(s) when the components such as Logic chips, USBs and even Serial ATA i believe don't need anywhere near what the 12v has to offer. Also, i'm not too knowledgeable on electric and components used to control it in general but i believe that would involve using resistors though i dont think they are used to convert power for all components through the 12v rail. If anyone has a definitive answer on this and could explain/link to an explanation i would appreciate it.

Oh right, so disagreeing with me, but you don't actually know..
