Re: Corsair PSu Fan Noise/ RMA
Get the XFX 650w XXX edition :) Will be near silent and produced by the top dogs Seasonic
I made the jump myself from TX V2 750w to XFX(550w) and was surprised how muh quieter my system became
Re: Corsair PSu Fan Noise/ RMA
Your GPU doesn't need 30A for itself, it is recommending 30A for the system as a whole. So yes you could easily use a PSU with much lower wattage, as long as it still has the necessary connectors.
OCZ ZS Series 550W (£45 @ Aria PC)

Better than Antec's HCG series because it is independantly regulated.

Yes. If I knew what GPU you were using I could elaborate more.
Describing your system fully might be helpful to anyone who wants to advise you.

As far as their PSUs go, some of their older/lower end units are worth avoiding nowadays. However the ZS Series is, as far as I'm concerned, some of the best budget units around.
Lots of positive reviews for the ZS Series:

So Antec's HCG series is certainly good, but not as good as the ZS Series IMO.
Judging a PSU based solely on it's brand isn't that wise IMO. This is because very few brands produce their own PSUs. Another important reason is because a brand will have low, medium and high end units. With quality and performance varying in each segment, so a brand's low end units might not be worth buying, if the brand is particularly bad then it might not be worth buying even their 'high end' units. Very few brands are so good that even their low end units are worth buying.
What is your budget for a PSU?
Re: Corsair PSu Fan Noise/ RMA
TPU measured the power consumption of that card by itself to be 180W at maximum. 180W / 12V = 15A
http://www.techpowerup.com/reviews/E...W_Signature_2/
180W seems a reasonable overestimation for what the rest of the system will draw.
http://www.fudzilla.com/home/item/29...iewed?start=11
Shows a system using an i7-3820 (more power hungry than an i5-3570K) and that card drawing 329W.
Some people talk about trying to achieve the optimum efficiency curve when 'sizing' their PSU. For instance, this is where the minimum load is more than 20% of the unit's capacity and the maximum load being 60/80% of the capacity. This is based on Ecova (the company behind the 80 PLUS certification system) starts at 20% for certification, so companies usually optimism for that. But efficiency curves obviously vary from unit to unit.
With high quality units the only obvious problem with drawing 100% of a unit's capacity should be fan noise. Perhaps the lifespan of the unit will be reduced, but if it's high quality then the system it is powering should be outdated/at the end of it's useful life even then.
Based on the above numbers you could probably use a high quality ~350W PSU, as long as it has two PCIe connectors. So anything above that is fine.
If you're thinking about SLI in the future or want the option, then four PCIe connectors is required. This number of PCIe connectors is usually found on 700W+ units, occasionally good 650W will also have that many.
Some high end options closer to £80:
Seasonic G-550 (SSR-550RM) (£77 @ OCUK)

NZXT Hale90 550W (£78 @ Scan)

Re: Corsair PSu Fan Noise/ RMA
Any noisy fan would drive me up the wall. I would replace the PSU if you can RMA it.
30A at 12v is 360W so a 400W PSU would be just fine
Get the seasonic from the list DIDM posted - it is rated 80plus gold for efficiency
Re: Corsair PSu Fan Noise/ RMA
GTX 570s are supposed to use more power than GTX 670s (219W TDP vs 170W), but I still think that a 750W PSU would only have been necessary if you had intentions to add a second card in the future.
It is quite common on internet forums for people to overestimate how much power systems use. Plus lots of people always think more = better, and things like better safe than sorry - even if there's nothing dangerous about using a 500W PSU for a single card system... just plain old ignorance most of the time.
I'd definitely take any of those I listed over a TX750. This is because two (out of three) have significantly higher efficiency and modular cables. And they all have slower spinning fans, therefore very likely to be quieter.
The original TX750 V2 uses a fan which has trouble spinning/starting up below 1000RPM.
Corsair's line-up is quite confusing/translucent atm, this is because they have added a semi-fanless mode to the TX series without much advertisement. The TX750s being sold now possibly aren't related to the original TX750 V2 either, again without much advertisement of this fact.
Yes I would say it's quite pointless buying a GS700, as the TX650 V2 is available for a similar price and it is exactly the same functionally, and it is supposed to be higher quality than the GS series.

Unless, somehow, you managed to buy an original TX V2 - without the semi-fanless mode - in which case the GS700 Bronze will potentially have an advantage; fan not spinning in idle.
Re: Corsair PSu Fan Noise/ RMA
Making multiple posts just to up your post count isn't gonna help you. Neither is repeating what I've said in the OP :P
But as you said, I won't be getting the modular to save myself one cable, and but I'll have to have a look around to see what PSU I end up getting.

oops...double post. The irony.
