I would say nice build and with 2 x GTX 560 ti, get the 850w because you will need the extra wattage if you planning to overclock.

@Novuake

Thanks for the suggestion. I did look at http://www.newegg.com/Product/Product.aspx?Item=N82E168... It is £5/£10 more than the XFX. I also looked at http://www.newegg.com/Product/Product.aspx?Item=N82E168... which is £5/£10 more than the XFX as well.

What do you think of them in comparison?


@sebastien

I was hoping to keep it modular/semi modular as it is my first build help me keep it clean and neat. I linked a similar PSU to Novuake above. What do you think of that one?

Cheers guys.

You can tell precisely how much power your PC requires in both watts and 12v rail amps. without any guessing from the link below. You can also objectively determine the performance and quality of the PSUs you are considering for your PC. Then you will be able to make an informed buying decision.

Unfortunately all PSUs from brand names like Corsair, Antec, Rosewill, etc. are not created equal or of top quality. The only means to know the facts are from reading objective test reviews of the exact model PSU that you are interested in.

Read this article - http://www.tomshardware.com/reviews/psu-manufacturer-oe...

Basically there are tons of manufacturers out there but 2 well known good manufacturers are Seasonic and Channel Well.
I usually recommend Corsair since all of thier power supplies are made from both companies, also the usually have great prices (after rebate)!

Any other power supply you buy may be good but the risk you take by buying a poor manufacturer may cost you a blown graphics card and power supply.

Good Luck.

Couldn't source the newer XFX xxx 850 in the UK.
The Antec and XFX model are Seasonic oems.
The Corsair a CWT.
All three would run your specs no problem.
The Antec TP-750 would be my choice if money is a factor.

A XFX 750W is enough even for SLI 2x GTX 570 with i7-2600k (without agressive OC of course)

You gonna be fine with any of these PSUs, but I would recommend XFX or Corsair, since u gonna use high wattage, the few better % efficiency from 80plus Silver badge gonna pay itself in the longrun

EDIT: from the options u sent, I would get the XFX 850W. It delivers 10A more in 12v rail than Corsair, and it's cheaper
October 21, 2011 5:05:26 PM

i bought that thermaltake 775w a week ago because its just amazing bang for buck and im very happy with it, also jonnyguru gave it a good review. jonnygurus unit performed like a 80+ silver even if this model is classed as bronze. its definitely enough for GTX 560 Ti SLi.

@billj214

From reading reviews it seams Seasonic and Corsair are the top of the market with XFX close behind and some good shouts to OCZ. Like you say you want to go with a well known branded card.


@davcon

Cheers for the links did remind me about Antecs.I did look at the Antec TP-750. Review sites usually lean towards the XFX though. They seem very similar.

One Antec I did look at was the Antec CP-850 http://www.newegg.com/Product/Product.aspx?Item=N82E168... I know this is designed for Antec cases but I have seen a few forum signatures with this selected with the Fractal Design R3. I did ponder if this would fit. They are £108 on Ebuyer


@vitornob

Hey, thanks for the reccomendation. I did look at the 750W as well seems the same price as the 850 and I guess the 850 gives me more possibilites in the long run with new cards coming out etc. Yer seems the Corsair falls behind there.

One thing I was worried about was the noise of the PSUs. I have been digging around on Kitguru to see some comparisons as I have sort of specced my PC for the quiet end.

That's why I did ponder about the CP-850 because of the noise suppression but the fitting in the case is the worry.


@Derbixrace

Interesting. I read that review before I do like the look of it. What did you make of the modular cables? I heard they can be quite stiff and some even short?


It seems the majority are swaying towards the XFX 850 Black Edition All I hear is good things about it and I originally had it chosen in my build. If there are no more suggestions I will happily order the XFX.

Yep the Antec and XFX are indeed similar both are made by Seasonic off the M12D design.
The Antec CP-850 is an excellent psu! never heard of folks using it in another chassis though,since it's purpose built.
I chose a HX-750 for my 902,hmm! wonder if a CP-850 would fit?

Actually SOME of the Corsair PSUs are top quality and some not so much. That is precisely why I posted above to check reviews for the exact PSU model you are interested in as Corsair buys their PSUs from several sources as does Antec and others and all models are not top quality PSUs.

Corsair uses - Seasonic and Channel Well, both are very good companies.

for me none of the cables were short or too stiff, i use the Silverstone RV03 case btw. that XFX 850 only has 6 amps more on the 12v rail so no biggie, also the thermaltake is more efficient and is modular. its just the best PSU for the money imo, as far as i know that thermaltake is made by CWT which makes one of the best PSUs.

There are tons of power supplies out there, I actually have a Zalman 1000w PSU but I can't easily recommend a power supply that costs over $350! So typically I recommend Corsair, Seasonic and Channel Well.

I would go for the XFX 850 W unit, its a very nice unit, well reviewed by jonnyguru, and being $10 cheaper than the HX750 makes it a much nicer choice.


@billj214, Corsair doesn't only use CWT and Seasonic, the AX 1200 is flextronic built so keep that in mind before you make sweeping generalizations. All XFX units are actually seasonic built, most are M12D or S12II or SS -xxx AT

The suppliers may be good companies but unfortunately not all Corsair PSUs are top quality. They've had their fair share of lemons. This happens when you build price-point PSUs. That's precisely why I suggest reading accurate, objective PSU reviews for the specific PSU model you are interested in.

All Corsairs TX/ HX/ AX Units are top quality power supplies from CWT/Seasonic / Flextronic (ax1200)

GS/CX (new) series are of ok quality with the CX430V2 the one i recommend the most for a low power budget build. If possible, i use alternatives from antec/seasonic/xfx if the 430 does not provide enough power but I don't require high quality TX/HX units.

The older VX units were of excellent quality if you can find em.

So in essence, Corsair has top quality PSU's to very good quality PSU's. Although not all of them are created equal and will work most of the time (lemons affect every manufacturer no matter if their corsair,antec,seasonic,xfx etc)
October 22, 2011 5:00:00 AM

Went to order the XFX got an email saying it will cost £112 for the XFX 850 due to delivery costs, sigh.

So now I am in a conundrum.
From reading what you guys have said the choice is basically between:

XFX 850W Modular Black Edition -- £112--

Or I could just pay the extra and get the 850 HX at --£125-- and have 2 years extra warranty or just pay --£105-- for 750 HX and get 2 years extra warranty too.

I noticed in the UK they do a TX 850 Modular version for --£108-- http://www.corsair.com/enthusiast-series-modular-tx850m... Haven't seen many reviews on it. I was working off Johnny Guru's TX 850 review and I could see there were some concerns about the Efficiency and the heatsink screws. The joys of heatsink screws.

TX-850M iirc are a new hybrid line (semi modular) made by CWT similar to the XFX Pro line. They're good units akin to the older TX V1 (which i have) but the HX is a tad high quality.

Just get the XFX 850, all of them are good power supplies and will not disappoint you.
