Hello

My basic problem is that I'm preparing build and can't decide on PSU

So specification of build
i7-4770k (possible overclock up to 4.5, probably will stay at around 4-4.2),
asus sabertooth z87
2-4 ram sticks 1.5v (so far 2 x 8gb but possible increase later),
1x sapphire r9 290 vapor-x (but also possible 2nd gpu later),
up to 6 case fans (noctua nf-s12a x1, nf-a14 x3, nf-f12 x2)
cpu cooling nh-u14s with 2nd nf-a15
1 x blu-ray odd,
1 x ssd (500gb)
1 x 7200 hdd (2tb wd green)
case corsair c70

At start I plan to use 1 gpu only but maybe I ll upgrade to 2x gpu later hence my PSU problem :).

When I used extreme power supply calculator with that setup, with all expansion up to 2x GPU in mind, OC to 4.5ghz, 4 ram and 20% capacitator aging it gave me 813w as min and recommended 863w and recommending 1000w psu.

Did i put that aging too high? Are those numbers accurate? I would like to keep that PSU for long time so will 860w psu be enough or should i really get 1000w+?

My 1st choice was Corsair RM1000 on paper it's features looks nice, but I read few bad things about RM serie, even that RM1000 is i think made with different parts than rest of serie. Also it's cheapest 1000w I found here.
So I'm thinking about some other brand maybe seasonic, enermax, evga.

Here is list of PSU from shop i plan to use to buy my build, which one would you recommend?
Prices are in euro.

850/860w
EVGA SuperNOVA 850 G2 - 119,04
Corsair RM850 - 130,63
Enermax Revolution87+ 850w Gold - 157,42
Corsair AX860 - 161,03
Seasonic X Series 850 - 173,23
Corsair AX860i - 183,83
Seasonic P Series 860 - 185,47
Enermax Platimax 850w Platinum - 238,85

1000w+
Corsair RM1000 - 155,6
EVGA SuperNOVA 1000 G - 163,2
Seasonix X Series 1050 - 195,11
Enermax Revolution87+ 1000W Gold - 195,78
Seasonic P Series 1000 - 217,71

And last question (i promise) if I would go with Seasonic for example is it worth pay that extra 12/22 euro for platinum (P) over gold (X) serie ?

Sorry for wall of text and hope for some good advice. Thank you

So going with P over X serie does not really give much benefit? Is it just that shiny Platinum certification? When i read few reviews now it looks like both can run at 89-90+ most of their typical load.

EDIT: To be fair I read little more, looks like P have even tighter voltage regulation and few more even more premium features and 7 year warranty instead of 5 which is for X serie.

So will probably go with that seasonic either X or P serie. Thank you.
 


Hmm ok will probably take X, but it's weird if X is superior why P serie got higher warranty and some better features. Not really noticeable for daily usage just on paper probably. But nvm that X looks really good and difference is minimal anyway.

EDIT: At the end i changed setup to single GPU and 850/860W wanted to go with P, platinum series for that extra kick and 2 more years on warranty until I found out that Platinum serie is one of biggest PSU, it got 19cm length and my case have in spec max length of PSU 18cm, not sure why, maybe there are some mount spaces which wont fit so I ll be taking X serie which is just 16cm in lenght.
