Building a £600-£700 rig for a friend, but we're trying to keep it future proof for a bit, so we're going to stick one R9 270 in it and add another later, using a pentium core but planning on upgrading to an i5 broadwell when they come out.

Only thing I am stuck with is PSU, my knowledge here sucks. Managed to narrow it down to these two though, just would appreciate peoples thoughts and advice as I'm out of comfort zone when it comes to PSU + multiple gpu's.

SuperFlower Golden Green HX 750W

Seasonic M12II EVO Edition 850W

Was looking around the 700W mark as we're going to want to overclock CPU/GPU and will likely add a few more HDD's in, not sure if 750 is totally overkill though, if so I guess this 650W SuperFlower would do the job?
 
Yeah been reading all morning, general consensus seems to be go for personal preference Personally feeling the Super, although the seasonic is modular!

So what about wattage? Would 650 be cutting it too close?

Even 450w is overkill for an overclocked i5 system with the r9 270.
 
I would have to disagree, for one 270 that'd do the job I guess, but we're going to be adding a 2nd one in later, and then I think we're going to want atleast 3 years of use out of the rig, so would want to not have to replace a PSU in that time.

I've run the rig through eXtreme PSU calc and that's saying 552W recommended with no capacitor aging and 90% load. Not sure how reliable that site is though.
 
Seasonic IMO they've consistently kicked around in the upper bracket of top tier OEMs whereas Superflower traditionally were at the top of the middle tier of OEMs though seem to be pushing into the top tier these days.

I didnt know that you'd add a second. If adding a second a 750w would keep things running efficiently and allow major overclocks
 
Your comparing a gold rated with bronze rating, in this regard the Superflower is better choice.

However, when you compare like to like reviews on sites such as Jonny Guru you normally find the Seasonic have better soldering and better fans then Superflower. Superflowers are still high quality PSU's, but personally I pay the extra for Seasonic.

I have the 750w version of the m12 evo and it's a superb unit. Allows great overclocking, the voltage movement is fantastic and it very quiet. I cannot fault it.
However the superflower is also another top unit. It's also gold rated , higher than the seasonic. But this does not always count for total quality. Being very honest there both top unit. The super flower is the new flavour of the month and it's what people are getting at the moment. They are pretty decent it seems. Though seasonic go back years and continually show there consistency when it comes to PSU's.

But it's about price and choice, either should be a good buy.
 
Yeah sadly there is no review for the superflower 750w from Johnny Guru, there's one from another model in that series but I am guessing build quality etc can vary quite a lot even in the same line up.

Thanks for the advice guys, at the end of the day they both sound very viable, I'll speak to my friend and see which he'd rather go for since it's his rig :)
 
May I recommend a Seasonic G 750w (SS-750RM), they can be sourced for £95, but you'll have to Google for it. I would take this over the Superflower you listed, yet still cheaper then the Seasonic X series PSU's.

Can't find a review on 750, but here is the 650g, it scores 9.8 out of 10.

Here is a review for a 800w Golden Green (i know you listed a 750w), below is the hot box test.

Here is the Seasonic 650w g hot test (can't find a 750w).

Open up those 2 hot tests in browsers next to each other, the Seasonic is clearly a better unit. Got to be worth another £13 over the Superflower you listed!
