Hi everyone, a novice calling.
A couple of days ago my GeForce 7950GT collapsed and i'm looking for a replacement. I barely use my old computer for graphic purpose (just a few Photoshop, a bit of non-rendered industrial 3D and no more games since a long ago...). After an intense quick learning research on the web, I am pretty sure that both nVidia GT 610 and GT 720 would perfectly work to me. I'd rather buy the newer 720 (a bit more powerful, more efficient, 4K UHD option, and pretty close to the oldie 610 in price). I have already ensured I should not have problems by (still) using WinXP, an Intel 945P based motherboard, and PCI-express 1.1.
The problem is that on EVGA's site (and only there) I've seen that the GT 720 requires a minimum of 20A at the +12v rail form the PSU, while the GT 610 just needs 16A (with an i7 @ 3.2 GHz refference PC). As my PSU tops at 380w it just gets 17A at +12v, but I don't know if my 2.4GHz Core 2 Duo can be compared to the i7. Both seem to have pretty similar TDP's at around 65w, but I'm not sure if that makes any point.

Question is: As I'm replacing a 82W TDP card (7950GT, which gave me ZERO problems in 8 years until now) with the 23W GT 720, does it defeat the Ampere shortage from the PSU? Would it work? Or should I go straight for the GT 610?
Thank you all!
