Need 1000w PSU recommendations.

[J-FRO]

Yeah, they're meant to start making straining noises as well when you start pushing them. That's extra noise you could do without as well!

Meaning you want a PSU that exceeds by a fair margin the combined power-usage of all the parts?

As in, while a 850w might be enough, if it's only just enough, it'll be running full-whack, which isn't good, right?

Yep, think of it as a car engine.

You also dont want to run a PSU maxed out.

+1 > 1000w, especially if your going to overclock your CPU + GPU'S as well, they say you should not take a PSU over 70% of its power, as you are starting to stress the unit which can effect stability in overclocking, etc, as well as reliability, the PSU is the No1 component in your build.

Probably the easiest analogy. Thrash an engine and see what happens to reliability, life expectancy, efficiency and power

My vote goes for the Corsair AX 1200W. Here is a review.

It may be £225, but for that money you get an excellent performing, fully modular and highly efficient PSU. Also, it comes with a seven year warranty - which gives you some peace of mind.

Still reading up on the recommendations, thanks for all the help!

Silverstone ST1000P easily. Good reviews and for £150 it's a steal. 100% modular and 80plus silver. It's small and silent

Do they do a better one? 1200w?

yeah. I think they have a 1500w aswell. I have only used silverstone.

Name it, give the OP more choices

I had a ST75-f, now I have the ST1000-p. They are both silent and very very good PSU's.

Corsair 1000W, the best PSU I have ever used. Highly recommended!

I was thinking of a corsair, but I couldn't justify £60-70 more for essentially, the same PSU

we have determined it needs to be 1200W+ for the OP.

post 26 is a goodun, but that 1500W silverstone strider seems a beast.

 

[Cleeecooo]

just under £200 for the 1200w SS. £260 for the 1500w

Just getting back to this thread, thanks for all the replies, I'm looking through them. I'm at a point where I'm reconsidering the 580, but as a reference I have another question that should help me no matter my decision.

So I've learned that you need to have a PSU that exceeds the total wattage needed to power a whole rig effeciently (keeping the strain below 70%), but is there a point that's too low? like if you buy a PSU that has way more power than you'd ever need, and you were only running like 40% (an example), does it lack efficiency then too (as in waste energy), or not work correctly?

Thanks for all the replies!

Yes, its best to run a high frequency switching mode PSU at around 50-60% for best efficiency.

take this bell curve for the TX750

And this differs for all PSUs? even PSUs of the same wattage?
