Info Beware of XFX RX 580 GTS XXX Edition

[Regeneration]

On November 26th, I bought an XFX Radeon RX 580 GTS XXX Edition 8GB (RX-580P8DFD6) from Amazon. The card was on sale for a special price of $189.

After I installed the card and plugged in the monitor (ASUS VG248QE) via DisplayPort, it started buzzing, despite the fact the PC was completely cut of power.

Then the entire PC began to misbehave (random "CPU overclocking failed" errors during POST, PC automatically powered up after shutdown).

Before the XFX RX 580, I was using GTX 970, everything was perfectly fine. I'm using UPS, all devices are grounded. PSU (Seasonic S12G-750) in a perfect condition.

I tried different DP cable, different monitor, different hardware, different outlet without UPS, but the buzzing at S5 never stopped. Therefore, I contacted Amazon and requested a replacement.



I received the replacement before I sent the card back. It was brand new, in a sealed box. And guess what... same problem, and even worse! The case fans keep spinning when the PC is off and power cable completely disconnected.

It appears the card is channeling voltage from the monitor to the PSU +12v rail. The issue is limited to DisplayPort. DVI and HDMI work fine.

Don't believe me? Watch for yourselves.

1st DP cable (came bundled with a monitor)

2nd DP cable (purchased recently)

Both DP and DVI outputs were damaged while making this video. HDMI still works.

Probably a bad batch of cards. If someone has a contact in XFX, please let them know about it.

@The Stilt Can you tell us why this is happening, please?

Were you ever able to get into Windows (and install drivers) and then adjust any power settings?

Oh and were you able to test with a different power supply?

Wow that is insane. How to screw up a power routing.

Oh and contact CS and return the card(s).

I'm not sure 3.3v is capable to power 3 case fans. And besides, the 2nd cable is a certified DP 1.4 cable.

Even with DP_PWR, voltage should never reach PSU's rails. Most TVs lack grounding and feed some voltage via HDMI... outputs must be shielded.

OS and power supply are irrelevant when power is completely off.

And neither is the GPU magically producing power out of nothing and destroying your system. Get a new DP cable. Doesn't matter that its certified, it can still be erroneous.
