Advice on Graphics Cards

[Alegis]

No clue about Motherboard, RAM and the like...

If u know model-names u can check the specifications online.
Ram usually uses up to 1,2W, nothing u cant handle

If u got a 450 - 500W PSU, u should be fine.

Got a modular PSU and a PCIE cable left and the one my 6850 uses atm has another 6pin added to it. Just unsure if this will be a pain to add xD My cable management could be waaaay better and using the 2nd cable would be annoying to put aside in my case.
By the way, length of the card shouldn't be a problem. My case got the option to remove a HDD cage for more space.

Shouldnt be a pain. If u got enough space for bigger cards, there should be space left to manage an additional cable as well


Edit: Zur not, wenns garnicht klappt mit dem zweiten kabel oder dem Netzteil, hast du bei Onlinekäufen ja ein 14 tägiges Rückgaberecht ohne angabe von gründen.
