850w PSU enough for Crossfire 2gb 5870s eyefinity 6 editions
May 28, 2010, 3:59 AM
I currently have a 850w Thermaltake PSU Crossfire certified It has the appropriate connections
Ati is not making much sense to me right now.
Crossfire 5970s ATI recommends 850w psu. 5970s used 300+ watts each. According to ATI "650 Watt or greater power supply one 75W 6-pin and one 150W 8-pin PCI Express® power connectors recommended (850 Watt with two 75W 6-pin and two 150W 8-pin connectors for ATI CrossFireX™ technology in dual mode)"
Crossfire 2gb 5870s ATI recommends 900w psu but they only used 228 watts each."600 Watt or greater power supply is recommended with one 75W 6-pin and one 150W 8-pin PCI Express® power connector required (900 Watt and 2 6-pin and 2 8-pin connectors for ATI CrossFireX™ technology in dual mode)"
If my psu will run 2 5970s won't it run two 2gb 5870s? Just trying to avoid forking over for a new 1000w psu.

2 5970s will consume 600w
2 5870s will consume 376w
2 5870 2GBs will consume ~440w
Yes, you will be perfectly fine with that.
I run 2x OC'd 5870s on a 750W Corsair + OC'd PII 965. No problems.
