Hi people!
I'm new around here, and here comes my first question...
I've decided to upgrade my antique gpu on my antique sistem to be able to run some new games even on medium-low (doesn't actually matter (sick of my actual gpu!)), until I'll be fully employed and be able to fully change the sistem.
But let's start with the begining....
I've this psu....pretty new itself, about two weeks since I got it for free
http://www.spire-corp.com/power-supplies/oem-400w-oem-atx-400w-pfc/
I've a motherboard that has pci-express, not actually sure what model it is, and I'd like to now what is the best Gpu that could actually be managed by this antique-new psu :D
I'd like change only the gpu, not the psu....since i've got it for free and the budget is really low but I really want to make a change.
I've been thinking about the following r7 250, r7 250x, gtx 650, gtx 750.

When you do upgrade your computer, make sure the first part that you replace is that cheap no-name PSU.
The model you listed does not have any PCI-E connector, and, going from the specs, has a maximum output of 15A on the 12V (for a total of 180W). This isn't a lot, even for a 400W unit. Your CPU probably uses 50-80W, a decent GPU is at least as much as that. Fans, hard drives and pretty much everything else will also draw some power from the 12V, so your options are pretty limited.

I recommend that (if you do not want to replace the power supply immediately) you use a video card that will not require auxiliary power from a PCI-E power connector.

Considering this, the best card you will be able to find meeting this requirement is the...

Without knowing the rest of your specs (at least the CPU and RAM), it's hard to make a valid recommendation, however.

Then again, I repeat that you should upgrade the power supply before adding a dedicated video card.

yes the 750ti would be best with what you have. just make sure to buy the single fan version because all the dual fans i have seen require 6 pin connector. evga makes a very nice overlclocked single fan version.
