Question  PSU Requirements? by Help4Noob


Complete virgin to PC building so apologies from the start if this is a stupid question but what PSU(s) would you recommend for this board with this Graphics Card QC: 43564 (Asus GeForce GTX 560Ti DCII/2DI/1GD5 DirectCU II 1024MB GDDR5 PCI-Express Graphics Card) please?

Don't want to under power it but certainly don't want to blow the backside out of the National Grid either :0)

Thank you for your time.

Answer by mohamedA on Tuesday, January 3, 2012
I would recommend a branded psu providing 600watts or more
like 43905
