Atrix 500T 600watt

Deadstuff · January 10, 2020

Hi there,

So normally I find a forum where somebody already asked the question I was looking for.

This time however I did not find any recent posts.

So I here I am

The problem: My corsair 800 watt psu died after 6 years So now I am getting a replacement form them.

But this takes a couple of weeks and my PC is my only device that I got in my home (outside of my phone wich I hate to use at home)

So I needed to get my pc running asap.

My dad told me he had stil a psu.

So I installed 1 hard drive and my motherboard to it and it works.

it's 600 watt so it technically should also support my 5700XT.

My question:

is it wise to connect a at least 10 year old psu (Atrix 500T) to my gpu.

or will it just die? I really can't find anything about the quality of the unit and my dad does not remember what he payed for it.

I also don't know how many years it was used before it was put away but it looks really clean on the inside.

there you have it I hope you can help me answer this question.

Thanks in advance.

No it's not, since with higher 12V power draws modern systems do today (especially with a hungry graphics card), group regulated PSUs like this with have a voltage control problem which causes 12V rail voltage to dip, 3.3V or 5V or both rails to shoot up. I dont know how much it will do so, so better not risk it.

And also it's 10 years old, can it even do what it's rated for? Taking about ratings, it's rated to do 600w+ but only has 500 in the name, so that 600w rating could be a burst rating that can't be sustained. Only bad PSUs do this which while I cant verify, causes worries.

Absolutely not. That thing is so old it has -5v rail.

There's some information about it here

Tldr; it's awful. According to the review it had MSRP of £30/$40, though I hope your dad didn't pay that much for it.

do not put one of these in a high performance dual core system.

It's not 600w, if you look at the testing page of the review I linked to above you'll see he didn't push it above 350w or so. At which point he measured 57% efficiency and 3.3v and 5v rails had dropped out of spec and 12v was as low as 11.48v.

Also, thankfully, you can't plug your 5700xt in to it since it only has a single 6pin PCIe cable.

Throw it in the bin.

Just be patient and wait for your new power supply to arrive. Which power supply is Corsair sending?
