So a buddy lend me a 7750, to test it since it won't run on his pc, and it worked! I have a really shitty "500w" psu with only 8A and 14A on the +12V rails. A few months back I tried a 9800gt and it didn't have the juice to run it.
Anyway I love the graphic card, thinking of buying one, BUT I was thinking of getting a 7770. So my question is will my poor psu be able to run this one if it couldn't power a 9800gt?
I heavily tested the 7750 and it didn't stutter at all, seems like the psu is handling it pretty well, the only problem I noticed is some games occasionally crash from a couple of alt tabs, but that's a crack issue probably.
PS. I also have a "450w" psu with "14A" and "16A" on the +12V, which was also unable to run the 9800gt.
And yes I know, I should really get some decent 50-60 bucks psu, but my budget is very very tight.
They are noname psus so don't think that will help except for the "sucks get new psu" comments, which I am very aware, but I decide to blissfully ignore those facts. Just need some input about whether this would work out or not, and why.
I wouldn't trust them. I had a codegen PSU catch fire directly in front of my eyes (thank god I was able to move the PC away from the curtain before it torched it >.>). Since that day I know that cheap PSU = trouble.
If you overload a cheap PSU, it has a good chance of blowing up.
When this happens, there is a more than good chance it takes your entire system with it.
Scrap getting the 7770 until you get a quality 500-600w PSU.
Might work, might not, might destroy all of your components. You have to ask yourself "am I a gambling man?" You said your budget it tight, so loosing everything is probably unacceptable. I kinda' look at everything in life as, if I can live with the worst case scenario then go for it. If worst case is too damaging, then I'll have to take a different route.
