What is the best Graphics card my PSU will power?

I am looking to upgrade my existing GPU (7600GT) to something a bit better, mainly because the fan on the card has broken and performance now sucks!

However, I'm not sure what my existing PSU will be able to power. I currently have a ColorsIT 500U which is a 500W power supply with 20A on the 12V rail and it does have a 6pin PCI-e connector

I was considering getting a 9600GT or a 8600GTS but am not sure whether the power supply will cope so if anybody could help me out it would be appreciated!

  1. I'd probably get an ATI Radeon 4890 (preferably the SAPPHIRE Vapor-X HD 4890 2GB), it will run nicely on your PSU. Which brand/model is it, by the way?

  2. The PSU is a ColorsIT 500U. I'm not sure the card you suggested would work with it as it requires 2 PCI-e 6 pin connectors and the PSU only has one, plus I'm pretty sure that card would require more than 20A on the 12V rail.

    The videocard comes with Molex to PCI-E 6pin adapters, you will be fine. ATI states on its website that any 500W PSU will run any 4xxx videcard series in single GPU configuration.
  4. Cool, although I'm still a little surprised it will power a card like that and to be honest I don't really have the money to pay for it! Does anyone know whether it will be good enough to power a 8600GTS as I've seen one of those at a price I can afford!
  5. My suggestion would be to upgrade/replace that PSU before you buy any GPU. You can get a decent 500w PSU for around 60.00$. This in turn will give you more headroom as far as the GPU sellection.
