I have a prebuilt pc that I bought over a year ago, with a generic 300w PSU - the pc came with no GPU. Almost a year ago I bought a ATI 6670 GDDR5 Graphics card after I asking for advice on this forum. Many of the PC elitists said that my cheap generic PSU wouldn't be able to support any graphics card. So far I've had no issues and my ATI 6670 has performed beautifully.
I have contemplated in the past upgrading my PSU, so as to support a CPU/GPU upgrade. However, I have concluded (after a year considering it probably) that spending more than a 100 dollars in further upgrades to my 400 dollar PC would not be worth the effort and expense. Nor can I afford more than 100 dollars roughly in upgrades.
I know that newer GPU's are using less and less power from PSU's, so I'm wondering if I can get away with upgrading to a ATI 7770 on my generic 300w PSU.
You should all take into account that PSU 'requirements' are not always firm, but more as a vague guide-line. In my own personal experience my 300w PSU has done just fine despite the experts telling me that it would kill my computer, and it's been a year now with my ATI 6670.
I have a rough idea that if the ATI 7770 doesn't use more than 10 or 20 percent more power than the ATI 6670, I should be Ok. Can anybody confirm this? Also, I'm a newb at computer upgrading, but I beleive some fancier GPU's require specific connectors or something. Hmm..
I'm also contemplating getting the ATI 7750, as I've heard it doesn't require any special 6-pin connectors, etc. With a generic PSU I could run the risk of not having the requirement connectors (not sure what they are exactly). Does a 8750 also not require any special connectors, does it use more power than the ATI 7750?
