A Radeon 7750 does seem to be the best in your price range of £80, although for £90, you can get a significantly better Radeon 7770. Can you give the exact model of your power supply? Overall wattage rating, perhaps surprisingly, is not very helpful in determining what a PSU is capable of.

The 7750 should work. The 7xxx series are more power efficient than their predecessors.

If I have any concern it is that the jump in capability may not be big enough for you to feel that you got full value from the change.

Your 450w psu should be strong enough to support a card as good as a 7850 or a GTX660ti.

Wattage doesn't prove anything. If its a crappy 450W, then it's not necessarily enough. If it's a good 450W such as at least a CX 450 or better, then it'll do the job.

Also, the 660 Ti uses far more power than the 7850. The 660 Ti uses only marginally less than the 670 which uses only marginally less than the Radeon 7950. It's best to have something more like a decent 520W or 550W such as an Antec 520/550 or better for the 660 Ti unless you're pairing it with like some weak low-power Pentium.

EDIT: also, the worst 7750 is a huge jump over even the best 6570. The 7750 that I suggested was far better than one of the worst 7750s too, granted it's not the best 7750 either. It's more than twice as fast as OP's current graphics. If we went by Tom's tiered recommendations, a three tier upgrade is a good upgrade, yet this is more like a six or seven tier upgrade.

That is not a name brand psu that I know of.
Still, it has the requisite power leads and is advertised to be able to deliver 28a, so you should be ok.
Try it.
If you find artifacts or other strangeness, then change ot the psu which will be the likely culprit.

Ok thanks for the help, ended up going with the Radeon 7750 after all, should do me fine for the games I play on pc any high req ones can always get for ps3 where available.

I agree, that PSU's specs seem more than adequate.
