The card I was going to go with is the EVGA GeForce GTX 750Ti Superclock w/G-SYNC Support 2GB GDDR5 128bit, Dual-Link DVI-I, HDMI, DP 1.2 Graphics Card (02G-P4-3753-KR)

Mainly based on its low power requirements. Now that I have a 500w PS, I wondering if I should get a more powerful video card.

Upgrading for Star Citizen. This isn't the first time Mr. Roberts has caused me to buy new hardware.

Actually the CX isn't all that reliable, its one of corsairs worst PSU's. While it most likely won't damage the system it uses cheaper capacitors that have longevity issues. Also a psus efficiency rating has nothing to do with what it can support.
"The efficiency of a computer power supply is its output power divided by its input power; the remaining input power is converted into heat. For instance, a 600-watt power supply with 60%...
I think you could, as long as you don't do anything crazy like going sli or crossfire.
It also depends on the efficiency rating of your psu, but you likely are going to be just fine.
The maximum you could go is a gtx 970, without overclocking or anything fancy.

Corsair makes reliable psu's so i think you'll be fine.

"The efficiency of a computer power supply is its output power divided by its input power; the remaining input power is converted into heat. For instance, a 600-watt power supply with 60% efficiency running at full load would draw 1000 W from the mains and would therefore waste 400 W as heat. On the other hand, a 600-watt power supply with 80% efficiency running at full load would draw 750 W from the mains and would therefore waste only 150 W as heat."

Not a great unit but there are many that are much worse. It will power most single gpu cards, atleast for awhile. In my experience they tend to start having problems at around the 1 year make but have seen them fail sooner and later. Whats your budget for the card?
 


We're talking about the AMD R9 270X, correct?

I am seeing it around $180-200+ on Amazon.
