Hello, friends. May I please ask for your guidance here? I am quite uneducated on these matters.
I am looking to upgrade my graphics card from a GT 720 1gb ddr3 card to the PNY GeForce GTX 750 Ti OC - Performance Edition - graphics card - GF GTX 750 Ti - 2 GB, which seems a nice buy at 150.00 and a substantial upgrade over my current card. Like the GTX 750 ti, my current card works on just PCI power (there is no 6-pin connector required, from what I understand). I also understand from reading that the 750 ti needs 20 amps, though I do not know if my PSU has that. It seems one would simply add all the 12v rails together, but clearly I should not assume that given my lack of knowledge on the matter.
Here is the information on my PSU:
Dell switching power supply (from a Dell XPS 8700)
DC Output: Max output power: 460 watts
+12VA--18A
+12VB--16A
+12VC--8A
+3.3V--17A
+5V--25A
-12V--0.3A
+5Vaux--3.0A
+5 and +3.3V shall not exceed 142 watts
+12VA, +12VB, and +12VC shall not exceed 385 watts.
Thank you for your time and effort!
Scott
In case it matters, I have a Core i7-4790 processor (3.6 GHZ), 8GB ram, a dvd drive, and a 1tb hard drive. I won't be running but a single monitor (21" flat screen from Dell).
