How to know if a card was used for mining

Myntekt · Sep 2, 2014

Hello!
Is there any way to see if a card was used for mining? I'm buying a card for -100€ on amazon (used, very good state), but I can't talk to them to have more infos.
Thanks

Unfortunately there's no way to tell what it has been used for.

You can only understand when you get the card. Check the temps, then Google your card and check for other people's temps with the exact same card. If yours are significantly higher, then it's probably used for mining.

Ok, thank you all

Another thing, will a 630W PSU be enough for this card?

Eduello · Sep 2, 2014

Myntekt :

Depends on the exact model. My guess would be no since I don't think I've ever seen a high quality 630W unit (I might be wrong on that though).

Eduello :

What happens if I use it anyways, and it isn't enough?

Eduello · Sep 2, 2014

Myntekt :

What is the exact model? A bad unit might fail, a really bad unit might fry your parts while failing.

Myntekt · Sep 2, 2014

That's where the problem comes... I haven't built the system myself, I bought it pre-built from a german webstore hardwareversand.de
I currently have an i7 3770K overclocked to 4,3Ghz altough the W8 task manager sometimes shows 5Ghz tops. I have it water cooled with a h100 and the system has 4 fans + 2 from the water cooler. I also have a Samsung Evo 840 SSD (250gb) and a 7200RP 500GB HDD.

I forgot to say that i have a H440 case, it has a "box" for the PSU and I can't really see that label. The only thing I know is that it is a 630W PSU and it is from BeQuiet.

Eduello · Sep 2, 2014

Myntekt :

That should actually be a decent PSU, so I'd say that you'll be fine. Just to be clear, what GPU are we talking about?

Myntekt · Sep 2, 2014

Eduello :

I said 630W but I'm not quite sure about that either, I think it's around 600W to 650W. And I've checked their website already but I'm not sure if the PSU listed there is the one I have, since it might have changed.

The card is the R9 290X, which consumes a lot, I think.

Hard to say if its enough or not...
If you want to use a 630-650W unit from BeQuiet, you should set the CPU to stock clocks IMHO.

I'll do that, but hey, they (where I bought mine) sell PC's with a 780 with the 630W PSU from Be Quiet!. Is the R9 290x any different from the 780? Will I see a huge difference when I set it to the defaults?

Eduello · Sep 2, 2014

You probably won't see a difference; A stock 3770k is easily enough for gaming.
The R9 290X is more powerful and more power hungry than the GTX 780.

Myntekt · Sep 2, 2014

I used a website to check how much my system uses, and with the R9 290X it consumes 658W with it overclocked, and 643W without. All this at 100%, whilst at 90% it consumes 597W.

Do you think it is enough?

EDIT: When I put Capacitor Aging to 20%, it goes up to 700W.
I think I'll just buy a new PSU. Which one do you recommend? I don't want to spend thaaat much 80~120 if possible.

Eduello · Sep 2, 2014

I don't usually trust calculators, but it's still a bit borderline. If you want to be 100% certain that it's enough, get a new PSU: http://pcpartpicker.com/part/rosewill-power-supply-capstone650

Eduello :

If I get a new one, I'd rather buy a 750 to 800W.

Go for it. If insufficient you will get lock ups, which means its the psu.

Why bronze and not gold?

Eduello · Sep 2, 2014

It's cheaper. Bronze and Gold only tell you how efficient the PSU is, not how good the quality is or how powerful it is.

Myntekt · Sep 2, 2014

Eduello :

Could you link me a modular one though? That one is semi modular, I don't really know what that is but I guess if I'm buying something new at least I want to get something good.
EDIT: Don't link me PSU, tell me the name, I'm buying it in europe
