Right first off i am having trouble with wiring my power switch to my motherboard , the wires coming from the switch are Black/White so i cant tell which is + an which is - , i know where it goes on the motherboard but will it matter if i put the - on the + and vice versa?
The second thing i need to ask about is , does anyone know of a decent PSU (650w+) fo under £55 ($85 USD)?
And my last thing is , can i crossfire a XFX HD4870 with a Sapphire HD4870 (Same clocks)?
I think the cheapest 650W PSU that has enough amps on the 12V rail(s) available in the UK is the OCZ Z Series 650W, which I know is still outside your price range, but I'm not aware of anything else that is cheaper and still good quality.
but it looks crap tbh , so im not sure to go for it , thing is , its got all the connections i need , especially the 8 pin power connecter for my motherboard (MSI 790FX-GD70) which is difficult to find.
ok thanks for the advice , could you tell me the bare minimum wattage for my system , MSI 790FX-GD70 , AMD Athlon X4 630 , 4GB XMS3 ,2 hdd's (1 IDE , 1SATA) , 2 DVD Drives ( 1 IDE , 1 SATA) , 2 HD4870's (1 at them moment but ill probs add another one) , wireless card , 3 fans (1 cpu fan , 2 case fans) and case led's
