What psu should I be running with an 8gb RX580?

[jd9797]

Ryzen 1700 w stock cooler
16gb RAM
Gigabyte 8GB RX580 XTR
4 case fans

What wattage should I be running? I am currently using a 450W psu and my computer turned off after 20mins of hard gaming. The screen went black/red and the computer restarted. The psu I have now doesn’t have an 8pin it has a 6+2.
Thanks for helping me!

6+2 is 8pin.
Your current psu is insufficient for running that gpu. Is this it? https://www.gigabyte.com/us/Graphics-Card/GV-RX580XTRAORUS-8G#sp
500w minimum, plus an 8pin AND 6pin.
Well, it may work for running at stock clocks and below, but beyond that, there's not enough power.
If you have a budget, I can recommend a new psu.

6+2-pin = 8-pin

It really dependson on the power supply. I would have gone with a higher wattage unit though.

Were you checking your temps?

What is the exact model of your power supply?

Doesn't your GPU have 8-pin + 6-pin power connectors?

Were you overclocking?

Here is a handy chart.
Check how many 6 and 8 pin connectors your particular RX 580 needs.

The chart says 550w.
I have no problem overprovisioning a PSU a bit. Say 20%.
It will allow for a stronger future graphics card upgrade.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

Regardless, buy only a QUALITY psu.
I like the Seasonic focus line.

Hi, yes that is the GPU I have. I'm running a EVGA 450B psu. I misspoke, the psu I have has a 6+2 and a 6 pin that I am using to power the gpu. Can someone recommend a reliable psu that will be sufficient? I am looking to spend less than $70

EVGA 450B. No, I was not overclocking. At the time of the crash I wasn't monitoring the temps, but earlier on higher settings, my temps were around 73C.

I dont believe JohnnyGuru has actually reviewed the semi-modular FOCUS units yet, just the fully-modular FOCUS Plus units with 10 year warranty.

Thanks so much! Also, this might be a stupid question but... I just bought these fans: https://www.amazon.com/gp/product/B01G5I6MRK/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

And my motherboard only has one fan connection near the front of the case where I will be mounting the fans. Will I be able to connect the fans directly to the psu? Will I need an adapter? The fans have standard 4-pin female connections

There are various adapters that are required to power your extra fans if you don't have the available fan headers. Some fans come with adapters.

SATA powered fan hub (best for lots of fans) https://www.newegg.com/Product/Product.aspx?Item=N82E16811984004&ignorebbr=1&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Accessories+-+Case+%2F+Rackmount-_-N82E16811984004&gclid=CjwKCAjwnLjVBRAdEiwAKSGPI1HHDMmhXpYZTgexEZnTHCmNKXx4BgzQB2fwyim5oEgyZ4YzB6CrshoCXlQQAvD_BwE&gclsrc=aw.ds

Should I get a 650W to be safe if I can afford it?

Yes, go ahead.
It is not so much a matter of safety as it is of being able to accommodate a high end card like a GTX1080ti in the future.
