Is this PSU enough for a RX480? And other power supply question

Electrolite · Jun 6, 2017

Hello I bought a RX480 but I noticed that I don`t have enough power to run it. The fans on the VGA start but then stop and after windows boot screen I get a black screen (monitor turns off saying there is nothing connected to it). I managed to run the computer on safe mode (so I don`t think it`s the video card`s fault, I hope at least).

Strange thing is that I own an 80 bronze 600w PSU so I tough it would be enough (yes it`s a bad PSU but at least the specs were on par with the requirements, and the specs are even kinda close to this EVGA PSU i plan to buy now. The old PSU is an Aerocool Strike X 600w)

I plan to buy this PSU:

I`m almost sure that it can run the VGA but as my old PSU failed I would like some confirmation to feel safer.

I heard that the RX480 really uses a lot of energy from the single 6pin cable and also from the PCI slot.
Could it be that my issue is the PCI slot? My MOBA is kinda old

My PC specs:
PowerColor RX480 Red Dragon
2 x Hard Drives
1 x External hard drive
I7-3770
1 x fan (not counting the CPU Fan
Motherboard Name Gigabyte GA-B75M-D3H

I don`t plan to do any overclock, Thanks in advance

You're going to have to buy a unit that has at least 550W of power. In terms of reliability you should pick out a unit that is as close to Tier 1 as possible.

Where are you located and what sort of a budget are we looking at? I wouldn't suggest buying that unit. Something of better quality from EVGA would be the 500B unit but is borderline for what you need.

I hope you mean the B2 there not the B1!

The Seasonic G 550w goes for $49 right now, it's the least I would recommend given the S12II 430w/620w are only a few bucks less.

Lutfij :

I live in Brazil so unfortunately my options are very limited and because the crazy high taxes my budget is limited as well.

So basically I would like to get the ''least bad option'' that would run my RX480 without burning.

My rig is very simple with only 3 HD and the I7 3770 and no overclock so I think there must be a budget PSU that can run it.

Unfortunately I found the 600w B1. Is it much worse than the B2? Because there is not enough offer the price jump for the B2 is just too much.

This is the model I found
