Dell Power Supply upgrade?

Thank you,could I run my sapphire RX 570 4gb,I think it's 150w? Wouid the 420w psu,be ok? I have gt 1030 in my other one,but wanted higher fps in the dt one..... 

if not,which would you suggest? 75w 100w card?

thanks.

It's not just watts.  What CPU do have in your 3010 DT?  That way, we can check for bottleneck.

Official AMD recommendation on psu for RX570 is 450W. Another source said 350W is good.https://www.techpowerup.com/gpu-specs/radeon-rx-570.c2939  It seems AMD or Nvidia official recommendation tends to be a bit exaggerated to cover all possible builts.  Even Nvidia has disclaimer that prebuilt system may require less power.  I think 400 W is probably okay for your RX570.

Thank you again,this site should pay you,as you do all the answering lol.

kind regards dan.

Graphic card and processor will work great together

Intel Core i5-3470 (Clock speed at 100%) with AMD Radeon RX 570 (Clock speed at 100%) x1 will produce only 1.49% of bottleneck.

you are correct. 

Your processor is too weak for this graphic card.

Intel Core i3-2130 (Clock speed at 100%) with AMD Radeon RX 570 (Clock speed at 100%) x1 will produce 36.54% of bottleneck. Everything over 10% is considered as bottleneck.

I think it's a i3 2130,which is too weak for that card so I will upgrade to i5 3470.

thanks.
