I'm building my first gaming PC but I'm kind of unsure if I have a strong enough power supply. I have these specs
CPU: Intel® Core™ i5-4690K Processor
GPU: Radeon R9 390 GAMING 8GB
Motherboard: Asus Z97-A
RAM: Kingston HyperX Fury DDR3 1600MHz 8GB Black (2x4GB)
Air cooler: Cooler Master Hyper 212 Evo CPU
Power supply: EVGA SuperNOVA 750 G2, 750W PSU
SSD: Samsung 850 EVO 250GB SSD
HDD: WD Desktop Blue 1TB
Monitor: BenQ 24" LED GL2460
On the back of the graphics card it says that they recommend around 750W, but it could also be higher of lower depending on the other components. Can anyone with more experience tell me if these components I listed require a higher power supply?
Look up the power draw for each component, or put them into a power draw calculator. Google one or just use PCPartPicker like everyone else. You're sitting somewhere between 500 and 600 by my estimate. You get the best efficiency at ~60% of PSU max if you care.
Please post in the >>>/g/sqt next time.

Just get a CoolerMaster G750M. I have been using them successfully for 2 years.
And yes 750w is really enough for that build

Thanks for the replies.
Also, I never used this board, so wasn't sure where to post.
>>55317818
Just buy Seasonic.

>8GB of RAM
I used to run a 390 + 8350 with OCs on both on a 700w be quiet! unit and never ran into any issues, you're fine
>>55318168
Is this a bad brand though? I read good things about it. I honestly don't want to cheap out on the power supply and have my computer fried.
>>55318168
>>55318755
The brand I have, not the one you recommended.

nvidia and amd overstate their psu requirements in case you've got a gutless wonder psu that can't deliver its labelled wattage. that build should consume around 420-450w at full overclocked load with an overclocked i7, so a good 500-550w unit will be more than sufficient.

on top of that, consider a few changes to your build to increase cost-efficiency:
http://pcpartpicker.com/list/dhkRGf
cpu overclocking doesn't increase gaming performance all that much compared to how much you have to pay for it. this locked i5 has a low base clock speed but you can set all cores to 3.3ghz via turbo frequency tweaking in bios.
an expensive mobo and cpu cooler won't be necessary if you go locked, you'll just have more ports and miscellaneous features that you'll likely never use
the 850 evo is fast but is overpriced to hell in the us right now. planar tlc drives like this corsair have theoretically (not in practice afaik) lower lifespans and long sequential writes are slower, but otherwise you won't notice a difference in day-to-day usage. also consider getting a single 500gb ssd instead of 240gb + hdd
the just-released rx 480 is equal to/slightly faster than the 390 while also being cheaper and more power-efficient. grab a gtx 1070 or used 980 ti instead if you're willing to shell out more cash.
case here is cheap as shit, but comes with two fans and will fit all your components with no problems.
the evga g2s are among the best psus you can buy, but a 520w seasonic will perform almost as well for about half the price. consult professional reviewers like jonnyguru for more info about both units and ignore any tier lists you come across.
lastly, i've upgraded your monitor to a 1440p 144hz freesync model. if you go for a 1070, get something with gsync instead, like the dell s2716dg.
>>55319360
Wow, okay that's quite a lot of changes. Thanks for the input. I'll look into all these components. I haven't considered them. I mostly looked at the ones I chose with some friends that built their own computers before. That does decrease my costs quite a bit though, so I appreciate it!

Seasonic makes gayming PSUs for like everyone, they just slap their name onto it and color it differently and write gayming slogans onto it.
>>55317818
bro i run a GTX 1070 on a 500 watt supply, no problems at all. you can undercut the wattage most of the time. i've never used more than 600W supply
Bad time to get a 390, get a 480 or 970 instead. (whichever is cheaper)
>>55319676
where I live the 390 is cheaper than both the 970 and 480.
are the windforce coolers any good? I have never had issues with any gigabyte product, but I have yet to buy any of their high-end cards.
>>55319810
They're quite aptly named. It'll keep the card cool under load while sounding like a jet turbine. If sound is a concern, Sapphire makes some of the quietest AMD coolers.
>>55319676
Not really that concerned about VR right now to be quite honest if that's their main driving point.
>>55317818
>I'm building my first gaming PC but I'm kind of unsure if I have a strong enough power supply. I have these specs
shit computer
>>55319898
So would this Sapphire card be quieter than the 2-fan windforce model? It's pretty much the same price.
>>55319999
There's also this XFX one that's around 30 dollars cheaper than both the giga and sapphire card.
Are XFX cooler and quieter than giabyte cards as well?
>>55319999
Yeah, the fans run slower and quieter so a third was added on to maintain the same cooling.
>>55320032
XFX is cheap for a reason, poor materials, poor quality control, and poor customer service.
