My new used R9 270x is DOA?

[wburton]

I bought a used Sapphire Toxic R9 270X gpu from ebay and when I installed it I got a black screen through post and boot. The fans on the gpu start. Duel bios switch did nothing. I tried everything else and I cannot get the card to display so I reverted back to my 7790 where everything works fine. I want to be sure its actually dead though. Is that a issue found in dead cards? My system should not be at fault though its older. I have an i5-650 in a intel dq57tm mobo (updated bios) and I have a 750watt antec modular psu. I'm trying to get a return right now but the seller is taking forever to respond so I have another card (a new one this time) waiting in my basket to be purchased.

Its probably dead. Only way to know for sure is to try it on another PC. But you can quite easily say that it is dead so don't bother.

Did u actually reset the CMOS, then with GPU installed + power connections + monitor connection to this new GPU; turn on monitor, switch the Input to the one you are using, power on the PC and wait a good 90 seconds?

UEFI/BIOS have to properly detect GPU cards, or it will not work.

To help ensure it does not try to boot to OS during this time; unhook any SSDs/HDDs; and wait until you have a working picture w/ BIOS screen.

If not, power down and try a different monitor cable/connection on GPU. It could be certain GPU-side connections do not work.

Yeah I cleared the CMOS. I removed power from the psu and unpluged from the wall with the gpu installed then held down the power button for a full 45 seconds. I did not actually remove the cmos battery though. I have also tried starting using the hdmi and dvi ports then tried switching between ports while the system was runnning and nothing. Used my old monitor to test but nothing. I even checked to see if the igpu ports were working instead but it seemed disabled as it should be with a card in the pcie x16 slot.

I also forgot to mention that at one time I had a GTX 560 2GB gpu installed and running no problem in this computer or at least until I installed windows 10 and got screen flickering/ blinking during important tasks which is why I got my 7790. That card used 2 x 6 pin power adapters to run. It was a 150watt card and the new R9 I got is only 180watt.

I wonder if the R9 cards wont work with this board or a pcie 2.0 slot. I have no way of testing though.

CMOS reset vs Battery remove = same thing. Both are means to reset bios back to default settings.

GTX 560 is approx 150W TDP as well.

If the R9 is more, and now u have issues; chances are the Power Supply simply is not enough.

And there should never be any Power adapters; the Power Supply should have those already; if it does not, that's a sign the PSU is not good enough, or too old already.

That PSU should be enough for any single GPU out there; however, if its aged, it might be very poor now; they degrade over time.

All I can suggest is trying a different PSU.

it shouldn't be an issue. most likely you got sent a bad card.

[chiefputsilao✖️ping]

you have a friend that can test your gpu in his pc so you can confirm the gpu is dead?

you have a good 750w antec psu.

Never buy used AMD card, most of them have been used for bitcoin mining 24/7.

Another reason I wont support them; they enable this kind of thing, something that shouldn't even exist.

I had a used radeon hd 7770 (on an older pc) and my current 7790 and they both worked great. I guess when you get into the more in-demand cards like mid-higher end cards the trashier the item. I was looking at Nvidia cards also before I bought the R9 and a ton of them were fakes by unknown companies like Vamery and RGB.

Probably my last ebay purchase.

I assume the seller will respond tomarrow to complete my return request because it will be monday. I think I gotta give up on this card. The only thing I have not tried yet was switching my mobo into uefi mode with the card installed and switched to uefi mode as well. Thats my last hope but I've wasted too much time trying to figure this out. I believe that I'm covered under the buyer protection program so I'm good for a return. A whole lot of waiting, stressing and wasting my time for nothing. Stupid eBuy frauds/ liars.

Never buy used anything to be honest, unless you're just looking for a temporary solution rather than reliable performance, or on a really really tight budget.

Yea when its PC hardware, best bet is avoiding "used"
Unless you getting from an IRL friend/family, etc and know how well they took care of it, best to avoid that sort of thing.

Lol yeah, totally AMD's fault. Sure.

[wburton]

Everything on my pc is used except the case, the cooler, wifi card and my input devices. Everything I have works like a champ. So used is not always bad. Instead of not buying used just don't go used on good stuff. If you wanna good part chances are higher that you will get junk. Older parts nobody gives a ♥♥♥♥ to scam anybody on because nobody cares to get old stuff. I will probably be doing a complete new upgrade in two years when this setup becomes very very obsolete. By that time I'll have all the money I'll ever need saved for a powerful new pc.

to be honest, R9 270 GPUs are not that great anyways.

280//390, sure.

Do you mean AMD or garbage from ebay? If you mean AMD its not their fault.

Were all the R9's just updated versions of the HD 7xxx series cards anyways? From all the reading I've just done over this damn thing the 7890/ 7990 cards were pretty bad. Lots of posts on google on those cards being dead or troubled.
