Specs: Windows, Amd ryzen
I was installing a gtx 770 to my potato dell Inspiron 545 when after turning on the computer, I remembered that the computer’s psu didn’t even have pci e cables. However the logo was glowing (fan wasn’t turning tho). Just saying that the only reason my computer managed to boot up was because the chip had integrated graphics, but I just want to know if this could harm my graphics card or the pc?

✔ Best Answer
No it will not harm the gtx 770, you can use the card for cuda acceleration and other compute workloads, im not sure if you will be able to game with it(but you can try, just plug a hdmi from the gtx 770 into the monitor) as it will try to pull all the power throught the PCIE slot, which i believe is max 50watt.

as of right now, it will just idle at 300mhz pulling 5watts, no need to worry

I believe that the PCIe slot supplies up to 75Watts.
If your power supply has the amperage on the 12Volt Rail(s) then you can get an adapter that will plug into two of your Molex connectors on different cable runs and have your PCIe plug for the graphics card.
I WILL however strongly recommend that you get a GOOD quality modern power supply with a single high amperage 12Volt rail, 80% or better certified efficiency rating, Active PFC, and a warranty of at least 3 years. This will both power your system including the graphics card but will also protect your investment. This is assuming that any power supply without a PCIe connector is either a very old one or a very cheap one, both are likely to crap out and take expensive components with it when under heavy loads.

You have to be a little bit crazy to keep you from going insane.

The reference specs for the GTX 770 show it to be a 230W card. It requires one 8-pin + one 6-pin power plug. Minimum PSU wattage of 600W. I think the Inspiron 545 has a 300W PSU.

It's a 5 year old card so not a lot of sites carry it anymore. Newegg only lists used ones. Here's a shot of the aux power sockets:
