You will need at least 400W for a HD 7750.

Probably depends on the quality of the PS. HD 7750 has been reported to work in systems with power supplies as low as 250-300 watts. There is no power connector on the HD 7750.

If you have any concerns with the quality of your PS, you can get an Antec VP-450 for cheap.

can anyone suggest a way for me to calculate my current TPD

the psu is a lite on model number ps-6301-08a thanks for any replys

You should probably upgrade your power supply if you're going to buy a 7750. That lite-on is a common oem model and isn't designed to handle much more than the system it was put in.

The HD7750 only needs around 5A running flat out. Your CPU needs no more than 6.5A. Check the combined amperage rating on your PSU's +12V. Allowing a few amps for drives and your mobo, and for the overrating common to cheap PSUs, if you've got 15A or more, you should be ok. Monitor the temperature of your PSU's exhaust during games; if it is really warm, or if the PSU's fan starts howling, you'll want to replace it. A quality modern PSU has full range active PFC (no little voltage switch) and some level of 80+ certification. The Antec VP-450 is a notable exception; it is a good PSU that does not meet those criteria (it is efficient enough, but is disqualified from 80+ because it doesn't have active PFC). Seasonic also has some excellent low-wattage units without PCIe power connectors that you could use if you don't plan further video card upgrades.

Edit: It looks like it claims to have two rails, one 10A and the other 13A. They aren't additive, but even if the maximum combined is 16A-17A, you should be ok. Monitor as above though.

Looks like you have 23 amps on the 12 rails.
#1 10amp
#2 13amp 23 amp total.
The 7750 need a power supply with 19 amps or more to work.
You are well within spec for a 7750 to run .

Which is your PSU brand?

While the PSU is definitely small and cheap, if it were bottom-of-the-barrel junk, Gateway would probably not be as large and successful as they are. I would not run a HD7770 on it, which I would probably be willing to do with a Seasonic or FSP 300W PSU; that said I think you will be okay with a HD7750.
Using the PSU calculator at http://www.extreme.outervision.com/PSUEngine I threw in an extra fan, card reader, 4x4GB of RAM, counting your drive as a non-"green" drive, added 10% capacitor aging and came up with 275W. If it's 2x8GB sticks, and a "green" drive, it drops down to 263W. In each case, the minimum was 50W less. I think you'll be ok.

Well thank you guys for helping me out think i will choose the best answer and probably will upgrade my PSU in the next couple of weeks just to be sure

Ty. If you do replace the PSU, a small Antec or Corsair should be no more than $45; either of those will have a PCIe power connector for a stronger future upgrade (if/when you want it).

Some Gateways have cheap power supplies like Bestec AKA Worstec. Others have other brands including Seasonic.

thank you i picked up a new psu to go with it and it came with free shipping and i am pretty sure i can run a 7770 off it instead of the 7750

Excellent, that's a good PSU. You'll be fine through at least one or two solid upgrades.
