After lots of research (mostly on this forum) I have found that my Vantec Ion2 520w PSU will be able to run the GTX 260 with no problems.
But I have just been down to my local PC shop and the guys there strongly recommended that I should downgrade to the GTS 250 or get a new PSU because I would be taking a huge risk with my current PSU.
So what do you guys think? I have been told that I will be fine with my current PSU by the people here, but down at the PC shop I was told not to get the GTX 260.
Any help would be great. I would prefer to get the GTX 260 but I don't really want to buy a new PSU unless it's absolutely necessary.
System is:
Intel Core 2 Duo E7500 @ 2.93ghz
4GB OCZ Gold Edition 1066mhz
WD 1TB Caviar Greenpower HDD
1 Optical Drive
1 Sound card
Vantec Ion2 520w PSU
No extra cooling or overclocking
Looks like 31.8A +12V. A little less than I'd like, but I still think you would be fine. Your system is far from loaded with an E7500, 1HDD, 1 optical, etc.
This would consume more power than yours as it's OC'ed to 3.5GHz with an OC'ed GPU (edit: also a GTX 260). Even tortured through Furmark and prime 95 at once, this system consumed under 300W at the AC source. Factor in 80% efficiency...we went overkill on the PSU needs.
Kind of sounds like the guy at the PC shop wants you to buy a new psu so he gets more money. I'll agree with other people on here and say that it will be fine.
The GTX260 requires a 500 watt psu with 36amps on the 12v rails and two pci-e 6 pin connectors. Look at your spec label on the psu to see if it has enough. Most likely if it has the two pci-e 6 pin connectors, it will be ok.
Vantec is a brand I am not familiar with, it may not have the quality to meet the specs well.
Unless you know the psu is insufficient, go ahead and get the GTX260 and try it. A small lack of quality power will show up in artifacts, and strange behavior which should cause no permanent damage.
It seems that the PSU has only 32A on the 12v rail...
Will the 4A really make a huge difference?
I would really rather have the GTX 260 over the GTS 250 but I would rather not destroy my PC.

Great answer!
I've been saying this and i'll say it agian.
I used to owned 400watts psu with 33A heavily used for about 3 years before.
It has enough juice to run Q6600 @ 3.0ghz and Gtx275 for 6 months before i found a great deal for case and psu combo.
