Hello guys, im in search of a new PSU my corsair ax860i as failed. I'm not sure what power requirements I need.

I was looking at 750w, but I'm not sure if that overkill brands and model I was looking at

Seasonic prime 750w
Evga 750 g2 /g3.

I will be overclocking my cup to 4.5 to 4.7 and overclocking the 980ti.

Either the Seasonic Focus Plus 650w or Antec High Current Gamer 650w (both are esentially the same psu in a different case) would be my choice. Both are Gold rated, fully modular and have 10 year warranties.

My basket at Overclockers UK:

• 1 x Seasonic Focus Plus 650W 80 Plus Gold Modular Power Supply= £92.99
• 1 x Antec HCG Gold 650W 80 Plus Gold Modular Power Supply= £92.99

​

So reckon 650w is enough?
