Wattage question .

loppol711 · Apr 22, 2014

My current purchase is this: http://pcpartpicker.com/p/3uvAD

The recommended wattage is 600 from the box of the video card, but I have a 500W power supply. Even though the total wattage is 416, would this be a problem?

probably

You would be fine, if the PSU wasn't poor quality. The CX PSUs tend to start failing when they are under a high load (this is due to bad capacitors). This PSU is a lot better: http://pcpartpicker.com/part/xfx-power-supply-p1550sxxb9

500w is plenty to run a locked i5 and 770. Your build will see a max power draw around 300-325w. Since you won't be overclocking, you should be ok. If you ever plan on upgrading your system and doing some overclocking, I would look into a better PSU.

Since this graphics card is already overclocked out of the factory, would it take up more power?

loppol711 :

Yes, a little bit. We're talking about something like 10-20W here.

Since the order was already placed on these items, I just want to make sure this psu would be fine in handling the system.

all around you are fine with 500 watts . . but not that cx PSU cause it is known for it's failure due to cheap caps and thermal issues. . but a good xfx or seasonic

Probably not. As has been said, the CX PSUs aren't great by any means, and are not designed for gaming (they are/were advertised as being used in a "basic computer"). If you want to run that risk, go ahead. I'd recommend sending it back and getting the XFX 550W which has already been suggested in this thread.

It's probably best to run your build by us before ordering parts, just for future reference.

What do I have to do to let you run the build?

I mean show it to us for review before you buy it.

loppol711 · Apr 22, 2014

All right cool. I'll return the one I purchased and get the recommended one.

The CX series is just fine for your kind of build. The CX series is not meant to handle heavy loads caused by high power draw and/or overclocking, due to its weaker capacitors. You won't be pushing the power supply too hard.

Their entire system draws around 325w at full load, and they use an overclocked i7 Extreme CPU. You'll be looking at closer to 290-300w at max load, which puts you around the power supply's highest efficiency. 500w is fine, and it won't be worth it for you to pay a restocking fee, and wait a couple of weeks to get a new power supply.
