PSU Question

[Baker]

Currently I have this:

420W TurboLink PSU
Asus nForce4 mobo
AMD64 3700+ SD CPU
2GB OCZ RAM
XFX 6600GT
80GB SATA HDD

and it all runs fine, CPU overclocked to 2.75GHz without needing to change the voltages at all..

If I were to replace the 6600GT with, for example, a 7800GT, would I be likely to need a new PSU? I am not considering a purchase at least for another 5 months so don't need any "don't get that, get this:" advice, just need a basic yes, no, or "you'd need to try it and see."

From a practical point of view I'm guessing your PSU doesn't have the 6-Pin PCI-E power connectors tha the 7800 will need. I know you can get adapters but it looks like these require 2 x 4-pin Molex connections to provide enough power, so have you got enough spare connectors for this?

From an output perspective it would appear that 400w is the minimum reccomended for a single card (SLI needs more) so you should be OK.

I think it does have these pins - not entirely positive but there are a few 6 pin adapters that didn't have a place to go when I built it up last month.

If I was buying a new GPU I'd probably buy a new PSU anyhoo. Thanks for input.

answered your own question then

"Probably," but I want to see what options I have, so I have plenty time to make my decision. I will be getting a large influx of money (harvest time ) around September, but still want to spend the minimum possible to get more performance.
