Hey! I've been reading reviews on a bunch of different models of the Radeon HD 7770 on Amazon and Newegg, and i can't find information about if i need to upgrade my PSU or not.
I have a 300 watt PSU, and i'm kind of scared to upgrade it because i have no one here to help me, and i have no way to watch How-To videos while i am doing it, i use my computer for school every day, and if i mess it up i'll be screwed, so i'm trying to do everything i can to avoid changing my PSU.
I want the best graphics card available without the need to upgrade my PSU, and the 7770 outdoes the 7750 (which i know wont need a new PSU)
thanks so much guys, but i really cant risk it. :s
i took the side panel off to upgrade my ram and put a second hard drive in, and even that was a struggle. haha.
I'm just really nervous, if i didnt have school it wouldn't be an issue, but over half my classes are online, and i can't afford to get behind.
i was thinking of taking it to a local computer store, but they wanted 299.99 for a 500 watt PSU, and thats a little out of the budget if include the price of the GPU.
another thing i worry about is when i was looking up PSU's, i read a lot about people getting shorts and wrecking their mobo or CPU or something.
Its really not that hard to upgrade the power supply. The 7770 would run on a nice 350W, but 300W is definitely pushing it.
EDIT: If you want step by step, I could probably help you.
thats very generous! but once my computer is unplugged, my connection with the outside world is gone. haha.
the only reason i can afford these upgrades is because it was recently my birthday.
college does not take kindly to my wallet. haha.
1. the radeon 7770 requires a pcie 6 pin connector which more than likley means 300 watts isnt going to be enough. stick with the radeon 7750.
2. why not ask them how much they would charge you to install a psu that you bought ? if its any more than $75 dont do it. if its within a reasonable price range the you would buy a psu from newegg and let them put it in for you. the whole think should cost you no more than $125.
EDIT: if you get an 80 plus certified shorts and damage to your computer would be less likely than it is now.
