R9 390 - 350W?

[ThinkWithPortals]

Hey all,

 

So, I'm going to sell my faithful R9 390. It's served me well, but I've fallen for the 480 NITRO so it's got to go.

 

Before I package it up and ship it out to whoever ends up buying it, I'd like to just pop it into a system to make sure it's not completely dead, just for my own peace of mind. Wouldn't be anything too taxing, just install the card and make sure the system boots with it and the clocks/temps are ok.

 

Thing is, the system I'd be testing it in is my father's office PC I built for him a few years back. What worries me about it is the power supply, a be quiet! Pure Power L8 350W unit.

 

I know it's ill-advised to run a 390 full-time off a 350W PSU, especially one of such mediocre quality, but would it be ok if I was just to just put it in, install drivers, check clocks/temps and then take it out, not run it full time? I ran a 960 in there for a while so it's not awful, but I wanted to know what you thought.

 

Cheers!

Along as it doesn't go to full load, it should be fine. Just don't open anything, along as it's at a somewhat idle state.

It sounds like a REALLY REALLY BAD idea

Really? Bear in mind I'd literally just be sitting at the desktop - not touching any games/benchmarks.

Yea why not, it's only idle no actual load being put on the GPU.

Let's rationalise here. An R9 390 can and will pull upwards of 280W if you ask it. That leaves what, 70, 60 50 Watts for the rest of the system. At that point the PSU will shut down. On the other hand, if you don't run anything that requires anything more than idle it will be fine. My advice to you is to keep it in your system until you sell it, the 480 Nitro won't give you any performance boosts anyway.

The 480's already in my system. I know it doesn't perform any better than my 390 but the 390 throttled in my tiny ITX case.

Their website says it's okay if you only do it for 16ms. 

So... Test quickly.

Then just package up the 390 and leave it there. You can put it into the 350W, but I'll shut down as soon as I get to the log-in screen.

Surely a 390 won't pull enough power to shut the system down even when it's on the lock screen?

Core clocks sometimes do shoot up and so will power draw (almost instantly) at that point your psu will just POOF and shutdown/explode 

Trust me i ran my 290x on a g600w from CM before. (before i got my g2 850w from evga)

I meant that I would shut it down myself as soon as I get video out.

[DXMember]

you'll be fine, if the PSU isn't made of cardboard then you can probably play a game or two on it as well

[Vode]

Don't worry about it man.

 

Nothing will blow up. Worst case the PSU shuts itself down.
