need help in finding right psu

[Next Revolution]

hey guys,

 

I'm currently upgrading my pc and I find it hard to choose the right psu.

 

I will be getting:

 

- Intel i5-4690k

- Asus Maximus VII Hero

- and a yet to be determined cooler    EDIT: watercooler, custom or AIO

 

and put them with my r9 270x into my h440 case.

I am not planning on upgrading my gpu in the upcoming years, but later on I definitely will get a better card and maybe SLI/Crossfire. I need to keep this in mind since this power supply should last several years at least 

 

I now have a MS-Tech MS-N550-VAL psu but I am pretty sure it is not sufficient, reliable (and good looking) enough for current and any future upgrades.

So I was looking for a new psu but I am getting a little lost. I found three that seemed good to me:

 

Corsair HX750i  @  ±150 euro (US$ 193)

XFX XTR 650W   @  ±105 euro (US$ 135

Cooler Master V700 (fully modular)  @  ±110 euro (US$ 142)

 

(Prices are in The Netherlands)

 

I would like to get some advice on which would be the best in my build or if there are better ones to choose.

the PSU's are good. choose the one you like! if I was you I should buy a less expensive motherboard and a better GPU.

Silverstone is a really solid brand too. As to what you need/want, well what are you going to use your build for? are you gonna overclock, are you gonna add another gpu, are you gonna add water-cooling? you have to give us more info buddy

GPU or CPU? cause I think cpu is more a bottleneck right now with my amd FX-6100 (stock speed)

I'm new in overclocking but definitely want to try that. As for the gpu, I already mentioned that for now I'm not changing anything but in 2 years I'm pretty sure I will change to single new card or crossfire with second 270x. I also want to get a water-cooler but haven't yet decided if custom or AIO (should have mentioned that indeed)

Well a standard AiO cooler usually have a pump and 1-2 fans, while a custom loop can have a really high powered pump and loads of fans (just something to think about). I have a 760W from corsair and that's plenty for me running a geforce 780, H100i, i7 4770k etc.

 

Ideally you could get a power meter and go to your friends house and get a reading while he stresses his/her system, and check what parts are in that rig and then work from that.

problem is I don't know anyone with such a rig, so I have to get everything of internet but everybody says different things in different cases which makes it hard to get a clear view of what I actually need

Out of the 3, I'd go with the v700. 

A cs650m would already be more than enough for cf though: http://www.alternate.nl/Corsair/CS650M-650-Watt-voeding/html/product/1110527?tk=7&lk=9533

You need to quote a post or tag a member or else they won't get a notification you replied to them.

Yeah, I just mentioned it if it was possible. What I did was add the power from the CPU and GPU, then I thought about what more I might add, and then add a little more on top of that. You don't want to put a 100% load on the PSU over any period of time. 

 

In my case I calculated an extra GPU in my rig, as I wanted the headroom for SLI if I was going to add another one at some point, think I came to something like 650W for a worst case scenario where everything drained 100% and then went for 760W just to have extra headroom (let's be honest PSUs last for a good while so why not "future proof"). So I have enough capacity for SLI and overclocking, and it won't drain 100% at all times, most times my drain is around 75W at idle and simple tasks like browsing.

 

The reason people say a lot of different stuff is that there's no good standard way to know how much you need, but add the GPU and CPU watts together and put on some headroom seems to be the way to go, remember that HDDs, SSDs, optical drives, fans, MB drains a few watts too.

thank you very much for the help, I think I'm gonna go with the v700 or hx750i just to be futureproof.
