Which PSU should I get?

[sapped]

Hey guys,

I'm thinking of building a new PC specifically for gaming, and am wondering which PSU I should get.
I'm really troubled by this since I don't know the first thing about PSU, so hoping for your help with this.

Here are the components I'm getting:

CPU: Intel Core i7-4790K 4.0GHz Quad-Core Processor
Mobo: ASRock Z97 EXTREME4 ATX LGA1150 Motherboard
RAM: G.Skill Trident X Series 8GB (2 x 4GB) DDR3-2400 Memory
HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
GPU: Sapphire Radeon R9 290 4GB Tri-X Video Card

This is the store I'm using as I can get a special deal there:
https://www.umart.com.au/umart1/pro/index.phtml?bid=9


But like I said before, I really don't know anything about power supplies, and really confused when looking at this list:
http://au.pcpartpicker.com/parts/power-supply/#sort=d6

I have no idea what the different efficiencies are, what are the recommended watts for my build and whether it's modular or not,
since this is my first time building a PC.

Here's some additional information, I don't know whether they are useful or not:
1. Yes I'm planning on overclocking in the future, but not decided on air or liquid cooler yet, should I leave more headroom for this?
2. I'm not using an optical drive.
3. I will buy a SSD later as well.


And for the PSU, are there some brands or series which are better than the others? And should I leave more headroom (more watts)
for the PSU for future proofing, so I can switch out parts like the GPU in the far future without hassle?

I'm really looking for the best bang for the buck here, but don't want to damage those expensive parts I paid and also not too limited as well.

Anyways really appreciate any help you guys can give!

Best Regards,
sapped

At least that's what I plan on getting

https://www.umart.com.au/umart1/pro/Products-details.phtml?id=&id2=&bid=&sid=196420 This should be OK for you.

I feel sorry for people that have to buy comp parts in Straya.

You can't find Biostar z97,which is sturdier,has a better BIOS and cheaper there.

OP: You picked some really expensive parts (i.e. not good for bang for the buck) but you aren't getting an SSD now. Is that a budget issue or another reason? If it's a budget thing, I would actually scale certain things back (i.e. cpu, mobo, etc.) and drop the spindle drive for an SSD. You would see a far better experience doing that than with the parts you picked.

As for your cooling, you need to decide that now unless you plan to start with one, throw it away, and switch to another. Since this is your first time building a PC and you don't seem too knowledgeable in the area to start, water cooling really isn't for you...

Hey guys, thank you all so much for your replies,

Just wondering, are the EVGA ones any good? They seem to have pretty good rating on PCPartPicker, their prices are also much cheaper than the other brands.
And also what about the Corsair RM series?

Also importantly what seems to be wrong with the Asrock Z97 Extreme4?
It have gotten really good review from Tom's:
http://www.tomshardware.com/reviews/mainstream-gaming-z97-motherboard,3824-27.html

And also on their december recommended list:
http://www.tomshardware.com/reviews/best-intel-amd-motherboard,3902.html

I was originally going to get the Asrock Z97 Extreme6 one but after some research it seems I will not need the extra features that the 6 offers

Why do you use PCPartsPicker when there is one site you want to buy from?

Hey guys, some complications just occured, and in dire need of your advices.

Turns out they don't have any EVGA SuperNova G2 750W in stock at that store, they only have the 850W ones.
However I need to buy all the components from that store in order to get the special deal there.
So I really don't know what to do at the moment.

The store staff say they may have new stocks arriving on the 20th of Jan, should I wait until then for the 750W one ($145 AUD),
or just purchase the 850W one ($179 AUD) right now?

750W already seems to be overkill when 650W is already enough for my new rig, and add another 100W on top seems to be a big waste.

I don't think I will go CrossFire since there's a lot of compatibility problems associated with the games I play. But on the slim chance that
I do decide to pick up another Sapphire R9 290 card in the future, will the 850W PSU be enough considering I'm also heavily overclocking
my CPU (i7 4790k) to 4.7Ghz? And add multiple fans, maybe even water cooler on top.

So I'm really lost on what to do. If I just stick to a single R9 290 in the future, will the 850W be a wastage? Like will it even be in the optimal
efficiency range for different load levels?

If so then I don't think there will be any point in spending more money on a less efficient PSU for my need. Although should I leave more
headroom anyway if I decide to upgrade to a new GPU many years later?

So what are your opinions about this? Really appreciate any feedbacks.

If you do go Crossfire, I would suggest that you get the 850 watt G2, without Crossfire the 650 Seasonic seems to be a good choice.

 

[TemjinGold]

OP: You will not go crossfire. Why? Because unless you are doing it right now, by the time you want to, it will be far smarter to sell your 290 and upgrade to the best single card out then. You will waste a lot of money if you are shopping for a PSU on the off chance you might do a bunch of very unlikely things.

do they have seasonic there and if so go with one of them..and try to get a gold series...they are better in many ways that i wont explain but ..if you could post other options we would be grateful ...

A good quality PSU is definitely recommended to provide (relatively) clean and stable power to the computer and it should last for many years.

Based on data in the first post, AND allowing for one optical drive PLUS one SSD, a quality PSU rated at a absolute minimum of 550W is suggested. However, to allow a bit for overclocking and for the possibility of Crossfire for two video cards, then a quality PSU rated at a minimum of 750W is suggested.

Note that these suggested ratings have a bit of headroom to allow for PSU degradation due to aging and to allow for slight variation in loads (video card(s) and overclocking in particular).

Looking at PSU's rated around 650W which allows a bit more leeway if overclocking and not using Crossfire configuration. Some recommended PSU's that are currently in stock at Umart.

SeaSonic M12II 650W
Antec HCG 620
SeaSonic 660XP² <- more expensive but with platinum efficiency

Best recommendation I've seen. Everything else is way overkill.

I'd also recommend getting the SSD now. Even if it means dropping down to a 285 from a 290.

He might, but this all is a great example of overthinking to the point of paralysis. Don't get me wrong -- I just built a new system and I spent a good amount of time analyzing every component that went into it. But, for each item, I had to just pull the trigger. Either that, or just put the build off forever... There have been several very good suggestions in this thread that would serve the OP's needs. I tend to go with the Seasonic that folks have been recommending in the link that has popped up several times. Stellar company with a very good PSU that will accomplish everything the OP wants/needs. And at a reasonable price, to boot.

The PSU is the heart of any system -- nothing will work right if it isn't a good one that meets the requirements of all the components. The Seasonic will do that just as well as the EVGA that has gone OOS.
