The ATI card lists a ps requirement of 650w the GTX 260 and GTS 250 both list 500w min supplies.
That might be pushing your 425w depending on how much your system is loaded. One thing to do is see if you can find the specs on your supply by looking at it. There should be a sticker on it listing the voltage supplies.
The GTS 250 would probably be OK on that power supply. It really is not in the same class as the GTX 260 or HD 4870 as these are higher-end cards. With the GTS 250 being basically a rebrand of the 9800 GTX+ but using less power, you will see that it used less than 300 watts of total system power so my guess for the GTS 250 is probably around 250 watts. Therefore, I think you have plenty of room with a 425W power supply.
Any of the 3 cards you mentioned are way ahead of the 3650. The GTX 260 will use the most watts especially if you are considering an overclocked one like the Black Edition. I would definately consider a power supply upgrade if you are going for this card. The GTX 260 takes one 6-Pin and one 8-Pin power connectors. The GTS 250 only takes one 6-Pin and the HD 4870 takes two 6-Pin connectors which you seem to have.

1- Has been put to use in the XPS410 with it's 375 watt power supply
2- Needs 2 x 6 pin connectors but doesn't use much more power than the 4870, may work with the existing 425w
3- The same power use as the 9800 GT that was offered in your machine

The GTX260 takes two 6 pin connectors I know Im running one and the draw is very mininual.

You're right. When I looked at the XFX Black Edition, it listed it as below but then right below this it said 2 x 6 Pin which I didn't catch.
Power Requirements:
Non-SLI: 630W Minimum Power Supply
SLI: 680W Minimum Power Supply
One 6-Pin Power Connector
One 8-Pin Power Connector
