Windows 7: Power supply good enough?

Power supply good enough?

So, I just recently got a new power supply (XFX Pro Series 850) and I was wondering if that would be able to handle a GTX 760?

I also have quite a few other things and was wondering if that would give enough for the rest of the stuff I have.

6 fans, SSD, HDD, Fan controller, NZXT RGB Hue, DVD-ROM, 8gb RAM, and also a wireless network card.

No expert mate but that card power requirement (I take it in full use) is 288watts looking at what else you have should be fine as the PSU is shoving out 840 watts on the +12v rail XFX Pro Series 850W Black Edition PSU Review - Legit ReviewsXFX Pro Series 850W Black Edition PSU - Introduction

I am not sure of the brand and I do see it is a single 12v rail which I try to avoid.

I am not sure of the brand and I do see it is a single 12v rail which I try to avoid.
It has Seasonic parts, which is one of the reasons I chose it. Plus the price.

I am curious why it says 500W minimum and 30 amps on the 12 volt rail psu for the card if it only uses 288W though.

And if you mean the brand of the graphics card, I'm thinking about this:

Always a good idea to run your computer's hardware through a power supply calculator:
eXtreme Power Supply Calculator

This will tell you (estimate) if the PS can handle the total load of the PC.

To see if the PS has enough reserve capacity to handle the load as it gets older (3 years +), use the "Capacitor Aging" box and select 50% (not all supplies will lose half their capacity in 3 years, more like 6 or 7, but this gives a worst case scenario: one or more deficient capacitors).

The crucial specification for a power supply is the amps put out on the 12v rail(s). You have to do a little math to see what is best for your particular setup. Sometimes a single 12v rail at 50 amps makes more sense than 2 12v rails at 25 amps.

Video card manufactures recommend power supplies by maximum wattage. Yours is saying that you should have, at a minimum, 500 total watts and 30 amps on the 12v to handle their card. They are, of course, assuming you have a "normal" PC setup - one hard drive, one DVD, etc. This is a general, blanket recommendation.

If the video card uses 288 watts we can calculate that it uses 24 amps at 12v (Amps x volts = watts). Therefore you know that you need 24 amps on the 12v rail just to run the video card. So a dual rail power supply with 25 amps on each rail with probably not cut it. Like I said, you got to do some planning. If you were planning on running 2 of these cards in SLI you might need to find a dual rail PS with 30 or more amps per rail. You would not be concerned so much with the total wattage, just that 12v spec.

Hope that helps!

288watts at 12v is 24 amps. Allow some headroom. The card spec reported at EVGA's site is 170 watts. Your PSU well handle a single 760 just fine.

I just wanted to be sure. I was debating between that or SLI a couple 650 Ti's. I'd rather go for the newer generation and not SLI.

I use this 850W PSU with a GTX780 so you should be perfectly fine.
