So, I picked up a new graphics card for my kid's old rig, and it’s a total non-starter.
The motherboard is an ASRock ALiveXFire-eSATA2, and it was running fine with a GT 740 until now.

Today I upgraded the setup with a Fortron Hexa 400 power supply, a new CPU cooler, and an MSI Radeon RX 470 Armor.
After cutting the tape and trying to boot it up, there's zero video output, and nothing else—not even the USB peripherals—is powering on. I even tried connecting via HDMI to a TV thinking my AOC monitor might be the culprit, but no luck.
Nade,
The BIOS is at version p4.00, which is the final update available for this board.
Is this just a compatibility dead end, or did I miss a step somewhere?
I have a backup option using an MSI G41MP28 (ms7592) paired with a Core 2 Duo E7500 if this current build refuses to cooperate, since I'm trying to avoid spending more money right now.😵

Just a silly question here—did you actually plug the PCIe power connectors into the card to give it enough juice?

Yeah, I'm seeing movement—the fans are spinning and everything seems to be powering up, but there's absolutely no signal on the monitor.

Hmm, maybe try pulling the CMOS battery out from the motherboard and leaving it out for about 2 or 3 minutes? That should reset the whole BIOS. If that doesn't do the trick, you might want to try popping your old GT 740 back in just to see if it actually gives you a picture...

I've already gone ahead and reset the BIOS. The old graphics card is still functioning just fine, no issues there.

If you happen to have another PC lying around, maybe try popping that Radeon RX 470 in there? If it works fine in a different machine, then we know the issue is definitely with the graphics card itself rather than the rest of your setup...

That is likely the cause. I dealt with an identical situation with a brand-new build; they actually replaced the motherboard before the GPU was even identified as faulty. Just my luck, I suppose.

It seems obvious that the power supply is insufficient.
Your old card pulled about 64W,
but this new one pulls double that!
A 400W unit isn't always enough. That number doesn't guarantee high wattage for the GPU; you have to account for the GPU, the CPU, and then factor in the drive, optical drive, motherboard, etc. You need to look at what the power supply actually delivers on the 12V rail. The 12V Wattage is what matters.
The same issues every single time.

If the CPU needs 90W and the GPU needs 120W, you're already at 210W before you even count the hard drive or the optical drive. Let's say your max draw hits 240W.
In that case, a power supply providing exactly 210W on the 12V rail won't cut it.
You always need a buffer. Power supplies tend to degrade significantly after just a year or so.
In this scenario, you shouldn't just aim for 240W on the 12V rail; you need extra headroom. Aiming for 300W would be much better if you want it to last for years.

The processor is rated at 65 Watt, so I don't see why the power supply would be the bottleneck here.
Plus, the PSU is brand new.

My mistake. It isn't 65. The processor is actually 95. I had some random, off-brand 300 Watt power supply running before and it worked just fine.

Does the CPU have integrated graphics? Perhaps you plugged the monitor into the wrong port.
I am not entirely sure about this AMD processor, but could the issue lie there?
Is it possible you see the CPU-VGA image in the BIOS first? I cannot say for certain.
Could the power supply be failing or worn out? Or maybe the rails aren't distributed correctly. That PSU has two 12V rails—one stronger than the other. If you pull everything from just one, there won't be enough current for everything.
It is also possible that ASRock—which, in my opinion, produces the most problematic motherboards in the world—is having issues with the new card...
I bought an ASRock board for my brother once because he wanted the cheapest option available.
It worked fine for only seven days. After that, it would only run if I lowered the CPU frequency by 5% or 10%, I can't remember the exact amount. Where else am I supposed to increase frequencies if it won't even run at the stock speed?

There isn't another GPU available right now. I’m a bit confused by the dual 12V setup because I only have one 8-pin connected on my power supply. As for ASRock, I haven't run into any more or less trouble with them compared to other brands.
Now I'm going to plug the card into this MSI G41MP28 motherboard paired with a Core 2 Duo E7500. Since it has integrated graphics, I should at least have some way to see what's happening on the screen.

>>1>> Sandra Cook60 is back at it with those voltage arguments—and honestly, it always comes down to the power supply. Look, a Hexa unit is a solid PSU and should have no problem firing up a graphics card like this. If the issue were actually the power supply, you’d see it happen when the card hits full load and starts pulling more juice, not just while it's idling. So, I'm leaning towards it being an issue with the card itself... if the motherboard was the culprit, the old card wouldn't be working either, right? And we can probably rule out the monitor too.

That Hexa setup pulls an extra 80 Watts, which brings the effective draw up to 450W. If the issue were actually the power supply, you would likely just see the fans spin for a second before everything cuts out, or the power button might not even trigger a response at all. Why not head over to a friend's place and test it there? It’s the best way to figure out if the graphics card itself is faulty or if something else is causing the trouble.

Just putting this out there. Now I’ve got the Radeon RX 470 running on an MSI G41MP28 board.
Turns out that ASRock board was incompatible after all.
Everything is assembled, and now the kid is testing out the FPS.😀
Specs are an E7500 processor, 4 gigs of RAM, and a Radeon RX 470.

I’m a little confused there, because a PCIe slot is a PCIe slot, right?

Supports AMD CrossFire
- 1 x PCI Express x16 slot with PCIE Switch card or 2 x PCI Express Graphics slots for AMD CrossFire
- 1 x PCI Express x1 slot
- 3 x PCI slots

So, you put the graphics card into that first x16 PCIe slot, didn't you?

Yeah
It didn't happen to me either, but hey, it happens.😀
