Which Power supply should I use?

[Gamer_for_life]

(I'm in the UK BTW)
If I were to have an i5-3570k and an ASUS R9 290 OC 4Gb what power supply should I use? (Whats the lowest wattage I should be able to go at) as I'm not good at figuring out the min and max wattage.

For such a high-end video card, I recommend no less than 600 Watts.

What about this one?
Corsair CSM 750W 80+ Gold Certified Semi-Modular ATX Power Supply (CS750M) - PCPartPicker United Kingdom

It's gold validated, 750W, modular and from a respected brand.

That PSU is made by Great Wall which is not very good. Get a Seasonic made or a Super Flower made.

Wait what? The one i linked to?

 

[Celery]

Yeah, Corsair uses a few makers for their line and this one has the maker with poor reviews.

 

[BikerEcho]

Hmm. Haven't seen any reviews with it. I just saw a gold validated modular 750W PSU from corsair to a good price. If it has gotten bad reviews than maybe this one is more up the ally: Corsair RM 750W 80+ Gold Certified Fully-Modular ATX Power Supply (RM750) - PCPartPicker United Kingdom

I know for a fact that this one is a good one. It's 12 pounds more. But that's properly worth it if the other one have bad reviews.
It has as similar specs. This one is fully modular though.

Sigh, another poor choice. This one is made by Chicony Power and also questionable as to their components, especially their caps.

Get a Seasonic and be done with. They use Japanese caps which are high quality.

here's the Corsair models that's made by Seasonic:

400CX
450VX
650TX
650XV2
750TXV2
850TXV2
450HX
520HX
620HX
650HX
HX650
650AX
750AX
AX760
850AX
AX860

I simply don't agree in your opinion. It's definitely not a poor choice.
That PSU have gotten good reviews and it come at a fair price, Why does it HAVE to be Seasonic.
Seasonic is a fantastic brand, no doubt about it, but they are not the only company in the world who knows how to make PSU's.
