Question.

[Kanaju]

So, I'm planning on buying this card: http://www.newegg.com/Product/Produc...82E16814162016 at the end of the month for my Inspirion 530s.

I keep hearing something about PSU and watts, etc.

Will my computer be able to run this card with no problem?

We can't help if we don't know how much watt and amp your PSU gives. ._.

WELL.

How do I find that out?

I'd rather get this if you had to go low profile and stock PSU.

Huh...

Significantly cheaper too.

... alright. I'll take this one.

But I'd still like to know the answer to my first question.

Open up your case and look at your PSU. If it gives an indirect amount of amps, take the total power, subtract by ~80(they usually overrate it, like it says 500W, but it can only supply 300W, mostly in OEM PCs) and divide that number by 12 and there's your AMP. For example, my PSU gives off 588 from my 12v rail. 588 divided by 12(from your 12v rail line) and it equals 49, there's my amps, it's 49. If yours have more than one 12v rails, take the total watts it's rated as, subtract ~80W(explained by before) and divide by 12 and there's your COMBINED amps from your multiple 12v rails.
EDIT: Dam you SnOw, you beat me to it, but yours doesn't include multi-rails.

It's on your PSU itself in your case, so you'll need to screw the case open. We need the information on the paper like above.
