600w PSU good enough for gtx 1080, i7-6700k & asus z170-a?

conormcgregor809 · Feb 20, 2017

Hi! I just got my evga 600w 80 plus white. The thing is, 2 people already had told me that, the psu isn't good enough, they mean about quality. Also do you think the watts are okay? Because I used the calculator, and the calculator says that, the recommend PSU Wattage is 437w. And the load wattage is 387w. And the calculator recommended me evga supernova GS 550w. So I went with the evga 600w 80 plus white, since it has more watts. I would be using the GTX 1080, i7-6700k, and the asus z170-a as motherboard. What do you guys think? I can't afford another PSU since I already ordered and I received it already the evga 600w 80 plus white. My father would kill me, if I tell him that I need a different power supply from the one I just got delivered. Here's a link so you can see the full specs of the power supply I got.. Thank you!!

Hi, The power supply would be ok, in my opinion, but the board might need a BIOS update to support the Kaby.

Wattage is enough, OCing brings it close to max.
They are right about quality. Cheaping out on the PSU is a bad idea, while your system will work, the PSU can also not supply ample system power as often as it does. I'll leave that thought there.

Well, I know is not a good idea buying a cheap PSU. But the thing is, that I thought evga was a good psu brand, since I always hear about it.. Also it has 80 plus, which from what I also hear, when a psu has 80 plus, it means is good quality. So will that Power Supply I bought, will it kill all my components? I know that in the future I would have to upgrade that power supply, but I want to know, that if for now it would be okay to use it without worrying about anything?

The PSU isn't a good quality unit at all, but it will run a 1080 just fine.
Regulation etc. might be a bit unstable, just don't try to push it.

i'd not try any overclocking with that psu. it'll handle the load at stock speeds but is not designed for long term high loads like you'd see overclocking an i7 and 1080.

the i7 can be a power hungry beast when overclocked. more than 50% power increase for small gains and even higher usage at high oc!! do yourself and your system a favor and leave it all stock for now until you can get a better psu. too good of a system to leave the chance on the table for something to happen when the subpar psu has an issue.

don't lose sleep thinking it's gonna blow up on you any second, not saying that

but rather use it for what it was designed for and that's nice minimal loads from a stock system.

Yes! I won't overclock because I don't like loosing the component warranty for just a bit of more performance. I even won't need to overclock, because I would have one of the best graphich card out there, and same with the cpu. I find it ridiculous overclocking for just some fps. Nah.. Yes, in the future for sure, when I get a better psu. xD Also, I won't need even to play at more than 1080p, because I'm getting a 1080p monitor, I know I don't need a Beast graphich card to play at 1080p. But I just like having good specs. So I shouldn't have a problem playing with a gtx 1080 and a i7-6700k without overclocking with that psu?

Math Geek · Feb 20, 2017

yah not a problem at all. at 1080p you'll be getting such good performance anyway that a bit extra from overclocking will seem simply frivolous

you'll be ok at stock speeds with the psu. it'll stay in a safe usage level. but think of it first, when you got some cash burning a hole in your pocket and feel like upgrading something.

Thank you!!

EVGA is a good brand with outstanding customer support. But they have basic models. The B2 is the minimum I'd get with the B1 being subpar. The G2 is half decent with the G1 being subpar. EVGA doesn't make their own power supplies so you can't just pick the brand and assume they are good.

80% efficiency means nothing. Just that the psu is efficient. It could still be crap.

Many of the EVGA power supplies are based on FSP, Seasonic, and suplerflower boards. You could get a Corsair and an EVGA both based on the same seasonic board. It's the packaging and features, cables, cooling, that differentiate them. You gotta do your homework before picking a power supply.

Chugalug_ · Feb 20, 2017

Pretty much, they have either fantastic power supplies, or sub par ones like the B1, G1, BQ (mediocre), 430w and white series.
A lot of the bad ones are manufactured by HEC, while the higher quality ones are generally FSP and Superflower.

80+ doesn't affect quality much. Most good PSU's have gold though, usually as well as good quality components inside.

Chugalug_ · Feb 20, 2017

Rating doesn't directly correlate to quality, it could be 80+ Platinum but use chinese caps and a single 12v rail.

Math Geek · Feb 20, 2017

that and rating has been shown many times over to not be enforced nor regulated. it's up to each brand to decide what it is and slap a label onto it.

that's why the testing that sites like johnnyguru and tom's here is so important. shows what the psu really is like, when they tear it down and test the crap out of them. i trust them when they say if it's good or not. the corsair in question here is not junk by any means. it is an average psu for an average pc. so long as you keep that in mind, and build accordingly, there is no problem with it. these actualy test rather well considering the parts inside. they compete with better and more expensive psu's often. a few drawbacks but nothing bad enough to avoid them.

this right here is actually why johnnyguru has such a long term issue with the tom's psu tier list. whomever maintains that list, was rather tough on the psu for no real reason labeling them as junk, when they are not. an average psu for an average pc is what it is intended to be. they have much better much more expensive units for high end systems when needed. people have trouble when they buy this psu for a high end multi-gpu super overclocked system. then it has issues, since it was not made for such uses.

conormcgregor809 · Feb 21, 2017

So, at the end of the day.. xD Should I stay with that power supply without overclocking? Without worrying that my components might get damaged?

Math Geek · Feb 21, 2017

yah no problem if not overclocked. i've used the same psu models for similar builds and not had any issues before. i'd not worry so long as you stay stock.

we just got a touch carried away with the commentary

xD Thank you again!

600w PSU good enough for gtx 1080, i7-6700k & asus z170-a?
