Hey so i just bought an gtx 1070 and i was wondering if my power supply is enough
my power supply is: 450 watts, autosensing, 85% PSU, EnergyStar 6.1, universal (110V-220V)
this is a prebuild gaming pc
my computer specs are:http://psref.lenovo.com/syspool/Sys/PDF/Lenovo%20Desktops/ideacentre%20Y700/ideacentre_Y700_Platform_Specifications-win502.pdf

I dont really have any money to upgrade atm so im just wondering if this is still cable to play games with high graphics

Minimum PSU for GTX 1070 is 500 watts. Using your 450 watt PSU can hurt the graphics card or hurt your other computer components. It is not recommended to keep using it. You should buy another PSU for it.

should i get this one for it then it has 600watts: https://www.bestbuy.com/site/evga-80-plus-600w-atx-12v-eps-12v-power-supply-black/8511029.p?skuId=8511029

Quality is equally important to wattage rating. The psu is put under stress for long periods of time in a gaming pc, it is arguably the most important part of the pc. You would be better off spending a bit more on a high quality 500-550w than a cheap lower quality 600w.

Which one should i get then?

Under 100$

can you recommend me from here:https://www.microcenter.com/search/search_results.aspx?Ntt=Power+Supply
This is my store to go to rather than buying online

I might get yelled at for this lol. I also shop at microcenter for my parts and picked this up recently.

https://www.microcenter.com/product/485308/750-watt-80-plus-bronze-atx-semi-modular-power-supply

It is rated for 62.5 amps on a single 12v+ rail.

I'm running the following

Ryzen 7 1700x stock speed
Asrock b350 pro 4
RX Vega 56- powercolor red dragon edition
16gb crucial ballistix ddr4 3000

That power supply is their house brand. I got it at the time because it seemed good for the money, and they haven't seen a lot come back. I went overkill on it though, plus it's only a few dollars more than the 650 watt. I also purchased a 2 year replacement plan for it, so far it's holding up well.

You could also get one like this.

Hey thnx so much im go head and get this one for sure.

 

[ohiou_grad_2006]

Disclaimer, I know don't know the attached quality on that unit or how it will perform long term, but if you mean the powerspec unit, it does feel heavy when pulling it out of the box. I'm just not sure who makes it and how long it will last. So don't push it to hard.

 

[khadkamon]

i just need it to run my gtx 1070 smoothly and my other complements

 

[ohiou_grad_2006]

As I said, mine works, and they said they've not had many returns, but those power supplies aren't well reviewed. So only time will tell how well these actually hold up. So far mine is doing ok since I've owned it. I would just caution running sli or crossfire or something on it.

 

[J_E_D_70]

I’d get an Evga G3 or Seasonic Focus Plus Gold. The CXM is more for office PCs. House brand is right out.

 

[ohiou_grad_2006]

Seasonic is definitely good.

I know the powerspec I got said it had Japanese capacitors, but don't ask me how much that means. Made me feel a little better that they weren't Chinese capacitors that a lot of reviewers seem to not care for.

But if you are willing to invest, those 2 options are probably better than the powerspec. Keep in mind, I have 2 year replacement plans on nearly all of my components so if my PSU does blow up, I can replace stuff like my motherboard, PSU, and GPU because of those warranties.

Go with any tier 1 or 2 off this list:

Pretty much the most simple way to pick one that won't hurt other parts.

 

[khadkamon]

thnx guys

 

[khadkamon]

would the EVGA SuperNOVA 550 G3 550 Watt 80 Plus Gold Modular ATX Power Supply or EVGA SuperNOVA G3 750 Watt 80 Plus Gold ATX Power Supply
work fine?

 

[ohiou_grad_2006]

I would go with the 750 personally if you can afford it. I just like having a little more power than I should need that way I've got a little wiggle room.
