Hi!

So I have an Enermax 550W 80+ modular PSU.
In the rig I also have
1) Intel® Core™ i5-4570 3.2GHz 6MB LGA1150
2) A 7200rpm HDD
3) 5 Fans
4) Some USB devices

So currently I am using a HD 5770 in it and obviously there are no problems with it. But I am thinking of an upgrade to a GTX 760 from EVGA and I have some doupts about it with that PSU.

From tomshardware info I found out that the GTX uses like 160 W at max and if I do a 160/12 + 15 + 5 , it seems fine actually.

But on other sites I see that the GTX 760 takes like 386 W or so at max. And if it is so then I have some serious doupts that it would work with this PSU.

PSU has been used for a week so it's not old yet. Just had a free HD 5770 to use and am looking for a upgrade allready.

Would appreciate help.

That 550w PSU will be plenty for your build. Because you won't be overclocking your CPU, too, you have plenty of watts. :)

550watt is enough for pretty much any single card. So yes it will do, especially with that power efficient cpu.

Nvidia recommends at least a 500w PSU with 2 -6 pin PCI/E connectors. Enermax is one of the better PSU makers. Unless you are going to overclock or SLI the graphics cards, I think you will be fine.

If say I should overclock one of the parts in future. For instance the CPU which can be overclocked only a little bit on the specific model. I will be short of power?

And how will it resist to time. PSU's get weaker they say in years.
I will not be ofc running this PC 24/7

It says like 535. But that would mean the PSU is at like 90% load all the time. Is that good?

No when idling your system will consume around 140w

when full load (i.e. gaming ~400w)
