PSU questions.

[no_alone]

Hello I have 3 pcs and 3 PSU...
Corsair CMPSU-450VXEU Retail
SeaSonic S12II 520 Bronze 520W

and I'm planning to buy a
SeaSonic S12II-620 620Watt 80Plus Bronze

I have 7 cards.
6 5850
1 5750

Will it run?

1 5850 and 1 5750 on the 450W

2 5850 on the 520W

and 3 5850 on the 620W

What do you say?

Haa and what is the different between 2x4pin molex to pci and 1x4pin molex to pci ?

I don't think that 520W PSU can handle 2x 5850, since it takes ~350W per card.

Crossfiring them adds +~180W. Dunno about running them both single. Same applies to the 450W and 620W PSU..

Edit: Read ahead to see that this post was actually a brainfart.

150W, max

Ditch my earlier comment.

Based my assumptions on :

http://www.guru3d.com/article/radeon-hd-5850-review-crossfire/9

regarding the wattage, I misread the card itself using as much as the SYSTEM in that article.

Thanks Monoquark for correcting me.

lol, 5870 takes max 200W (180W TDP but overclocked probably a bit more so there's no problem running that.
