hyperoxemia :
Whoa, thanks for the quick reply! So is it basically guaranteed to not work, is what you're saying? I'm kinda confused by the 3 options you gave, but I appreciate the response regardless!
It's just we don't have information about this power supply. There are a lot of PSUs that are tested by professional reviewers, but power supplies like this, Acbel, are generally considered to be very crappy. They are cheap and are generally unknown, which makes them "use at your own risk". Anybody who straight up tells you it will work or not is wrong because there is no evidence to back that up. A 750Ti is another 75W of load on that PSU, so who knows what it could do.
If you were to get a new PSU, what would you be willing to spend? The EVGA unit above is probably the best $30 unit, though it still is not the most reliable unit (hence the price) but at least has been tested by professionals and is certified to work well. Should last you a few years.
