PSU question current system and future build

welchs101 · Jan 6, 2017

Hi,

My situation/question requires a little background. I have a current system where the cpu/ram will meet basic minimum requirements. But i need to replace my video graphics with a board that my friend has...given to me temporarily until i can build a new system.

Here is my question: I have to buy a psu to go with an Nvidia GTX 680 so i can play "now" with my friends. However, i would like to purchase a psu that i can use for my "new build" later on.

I was thinking my future build would be with an I5-6500 and lets say a graphics card like this "Nvidia GeForce GTX 1060" . Now i have done some intial calculations on power calcs .....none of them are over 550W..........but despite this i was thinking of getting a 700W or 750W psu.

Does this sound stupid, reasonable or what? Also, what psu would you get.

Skylake consumes very little power, NVIDIA cards does that as well, going 700W or higher is a big waste of money IMO.
If you not going to OC ( which you won't, as you're getting a i5 6500 ) getting a PSU as strong as that isn't the best option.

Therefore, a good quality 500W PSU should do the tricky and be more than enough for your build.

If you wanna search for some models, check this list. Be sure to Stick to Tier 1 or 2 preferably.

I can recommend these PSUs:
XFX Pro 550W
Super NOVA G or B2 550W
Seasonic S12 520W

Any of them will power up you whole system with ease.

i need at least 550W for the GTX 680 card that i am going to use temporarily. So i need at least this however, i read somewhere that you want at least 100W above what you think you need.

welchs101 · Jan 6, 2017

are there any draw backs or negatives for having too much power?

welchs101 · Jan 6, 2017

i do agree that 700W is probably too much but since i dont know exactly what i will build just thought 700W was a good risk choice.

the GTX680 is a pretty power hungry card, drawing twice as much as a 1060.

an i5-6500+1060 could run on a 360W PSU
700W is definitely overkill without adding anything to your performance.
no matter what you will be building, you won't use 700W. 700W *could* power an i7 + 2x GTX1070s. this would result in a 2200$ built.
550W can power basically any single-GPU setup. 650W if you think you want to establish new OC-records and want to run your PSU at low loads for minimum fan noise.

if you're looking for something cash friendly, the XFX Pro / Core / TS 550, the Seasonic S12II-520, Super Flower Golden Green Hx or the Antec High Current Gamer / Edge in this range of wattage are your best friends
if you're willing to spend a bit more for a better unit, a Super Flower King / Leadex, Seasonic G, Corsair RMx or EVGA Supernova GS / G2 / G3 would be your go-to units.

would this one be ok?

welchs101 :

No, you need exactly 195 W to power up that GPU.
http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-680/specifications

The 550W recommended is to power the entire system. That is generic recommendation as they don't really know whats up on your PC. If you wanna see by yourself how much your system will draw, put all parts in here http://pcpartpicker.com/ it will tell you.

You are right about the 100W more than needed tho. PSU work at most efficiency at 50% of load.
But wattage is not the only thing you must consider, because there are lots of PSU that claims to have 800W and don't deliver half of it when really stressed. Even those that claims to be 80+. So you really gotta choose a good reviewed PSU. ( Which all of those i posted are. )

Your entire system will take about 3xx Watts in total to run. with + 100 Wattage headroom, you can get a 500W good PSU without a singles problem and everything will still work.

welchs101 :

it's a good unit.

as newegg said, johnnyguru rated it 9.8/10

manddy123 · Jan 6, 2017

welchs101 :

No, there aren't.
Your PSU will only draw the power it is requested.

The only downside is that you're paying for a product that isn't being used fully.

manddy123 · Jan 6, 2017

welchs101 :

Should be more than plenty.
A nice choice overall. Even more if you ever wanna switch that i5 6500 for maybe a i5 6600K or i7 6700K to do some overclocks.

With 620W you will have a nice PSU for overclocking.

welchs101 · Jan 6, 2017

night owl,

i could not find any info on these that you mentioned:
"Super Flower Golden Green Hx or the Antec High Current Gamer / Edge"

Isokolon · Jan 6, 2017

welchs101 :

Newegg doesn't have any Super Flower units

Antec has the High Current Gamer listed as HCG and the Edge as EDG.
taking a quick look around, price doesn't come close to the Seasonic. Antec seems to be quite pricey in the US^^

welchs101 · Jan 6, 2017

i think i know the answer but want to ask anyway........what do you think of this psu

welchs101 · Jan 6, 2017

or this one......... the last two i can buy today from local store so i thought i would just ask

http://www.bestbuy.com/site/evga-650w-modular-bq-power-supply-black/5622832.p?skuId=5622832

welchs101 · Jan 6, 2017

ok, one more.......what about this one

EVGA - 650W ATX Modular GQ Power Supply - Black
Model: 210-GQ-0650-V1

Isokolon · Jan 6, 2017

welchs101 :

no matter how Thermaltake brands their series - they're never a "smart" buy
EVGA series to be recommended are B2/G2/GS/G3. the other ones - not so much

price / value rating for the Seasonic G is extremely good.

if you really have to save a few dollars, those are fine.
but the price difference to the G is rather small and the performance not as good

welchs101 · Jan 6, 2017

never mind on this last one i posted they dont have it at local store

welchs101 · Jan 6, 2017

night owl,
qustion.....the seasonic G you referred to.........is this the one i posted? also, the link you provided for the corsair CX psu.......were you recommending this one or would you just stay with the seasonic

Isokolon · Jan 6, 2017

yes the Seasonic G is the one you initially posted.

I'd stay with that one.
however if you say you have to turn every penny and really can't afford anymore than 70$, not even 71$, then the Corsair CXM650 is alrightish. however the Seasonic G is a superior unit in terms of...everything

welchs101 · Jan 6, 2017

thanks......

welchs101 · Jan 6, 2017

hey just one more question.......this Seasonic G series psu.......would it work with most video cards and mother boards?

Isokolon · Jan 6, 2017

yes^^

it comes with standard specifications.
has a mainboard, 2x8Pin for the CPU, 4x 6+2 PCIe/GPU(not sure if all are 6+2, at least 2 are), 5x Molex & 8x S-ATA
should satisfy all your needs with ease.
