Is 700W enough for this build?

[Mattios]

So I'm looking at the Corsair GS (gamer series) 700W power supply with the following components:

• 
  ■ AMD 6300
  ■ 1x WD HDD 1 TB 7200 rpm
  ■ 1x Kingston HyperX SSD
  ■ 1x Standard dvd writer
  ■ approx. 5 fans
  ■ Two sticks of RAM
  ■ etc.

With two 7870's (XFX) would this PSU be OK? What about with two XFX 7950's (all double D)? What about if it was an 8320 CPU?

I also looked at the Corsair CX 750 but would this handle such a system (moved onto this GS series PSU because that may not handle it)

If this will not be OK can you please refer me to a decent PSU that can handle the above components (7950/6300) in the UK.

Thanks alot in advance

I was thinking about getting the CX750 but then I did a bit of research and decided to go with a OCZ 750w High Performance Series PSU.

My specs are:
Fx 8350;
Asus Sabertooth 990FX Gen3 r2.0
16gb@1600mhz;
And a Gigabyte GTX 770.

Edit: So yeah, it should handle it pretty well.

Okay, thanks

I'm now looking at the XFX Pro 750W PSU, how would this handle versus a Corsair GS 700?

Both XFX and Corsair make great PSU's and it doesn't really make a HUGE difference (Corsair's Builder series PSU's aren't the best) so I would get the XFX 😛
