Greatings,
So this korean brand 500W psu came with this pc. Specs are:
i5 3470
8Gbddr3
And I was hoping with I can add a gtx 780 or 970 with it.
The picture of this psu is:

And the only website I can find is:

My question: Is it ok to add a gtx 780. Can this psu afford that current.
Thankyou

the simple answer is no.
It's a super basic and cheap PSU.
It's not even 80+ rated as far as I can tell.

You first need to get a better PSU for it.

If on a serious budget then this is the best PSU I can recommend that won't explode.
(I mean, you could pair a 780/970 with it since it is a 500w PSU, but it's a trash PSU so I would highly recommend against using it with a GPU)

costs $55 on Newegg and if you take advantage of the mail in rebate, you'll get $20 of it back in the mail.

Otherwise, the current PSU you have just according to it's label has enough wattage to power the GPU and your system. And you can use it if you want, but you do so at your own risk.

no clue about the quality of that psu. but i would think it would support a 970 pretty easily. they only run about 150w or so if you don't try to run a super oc'ed version. you can get similar performance out of a newer 1050ti card and they use less than 100w. no idea what pricing is like for them but i'd look at newer more efficient cards first. then settle for a 970 if you can't get anything else.

the 780 uses WAY more power and i'd not trust one to that unknown psu. they start at 250w and go up from there!!!

best case is to get a new psu that is known to be a quality unit.

So i Replaced the psu with 500W Antec EarthWatts psu.
And now I’ll be adding a GTX 960 or a GTX 1050ti because they’re less heavy on psu then other cards.

That PSU is bad.
Probably better than what you had inside the system in the beginning.....But not by much.
I do hope the price for that PSU was cheap enough it was to make the risk of using it worth it.
Best of luck.
