Hi guys,
I want to change my old 65nm XFX GTS250 1GB to HD6870, but i know that most of the hd6870(maybe all) are 2x6pin, so i want to ask is there hd6870 with 1 6pin reqiured? If no , then i think i will change my GTS250 to MSI HD6850 Cyclone with 1x6pin, do you agree that it is the best option ?
This is my system:
Q9400 2.6GHz OC to 3.6
500W
4GB DDR2 800

Also i dont want to buy a new PSU!!

What is the brand and model of your PSU? If it is a good one, you'd have no trouble powering a HD6870, GTX560, or perhaps even a HD6950 or GTX560Ti.

Actually the HD 6870/50 doesn't consume too much power, but the Molex adapters from cheap nasty PSUs are not trust-able, so i guess it's time to change PSU.

The HD6850 is only 2 tiers higher than the GTS250. To see a major performance improvement you will need a 3 tiers difference. The HD7850 is soon to be released. It may have 1x6pin and at least a HD6870 performance.

In general I do not recommend anything less than 80 plus certified units for high powered video cards. However in this case, your PSU supposedly puts out 30a on a single +12v rail which is enough in this case.

However, your PSU also has passive PFC, which is not good. You really want active PFC. What passive means is that if the PSU blows, it can and very probably will take other components with it like your motherboard and new video card..

It is up to you. If you could let us know what your shopping options are, we might be able to locate a good unit at a reasonable cost.
