HD 7850 OR GTX 560 Ti Overclocked + PSU?

Hi,

I have Dell XPS 8300 therefore I obviously suffer from capacity/PSU problems. My PSU is 460W and as far as I'm aware - Dell have wonderful PSUs. Anyway, 7850 requires 450W, although on some websites it states that it requires 500W. If I decided to buy 7850 I believe that my PSU would be good enough. If however I chose to buy GTX 560 Ti (OC), I would need to upgrade my PSU. The cost of 7850 is exactly the same as 560 Ti + PSU.

7850 on you're Dell PSU would be perfect.

The 7850 is cheaper, uses half the wattage, and is just a little better than the 560 ti.

If I'm not mistaken it's better by a fairly decent amount. Since 560 Ti would be overclocked the life span of it would be decreased, correct? Therefore the 7850 is truly the perfect choice for Dell XPS 8300 users, am I correct? I'd love to read a post or two more regarding this matter.

When is the forum glitch going to be fixed, it's irrelevant, I know. It's just getting very frustrating.

Why is no one replying? Is my answer to my question too obvious?

True, the lifespan will be shorter. But electronics are generally reliable today that it would be long obsolete before it fails barring manufacturing defect.
But in any case, I believe the 7850 is a good choice if your PSU already have a 6PIN PCIe connector in it. If not, then you might need to upgrade the PSU afterall.

7850.. uses less power ... and well has better performance

Alright, I'll get the 7850, from what I've read it does have 6pin connector, I'll open up the case before buying just to make sure. Any other opinions?

Good idea. It pays to be sure.

Of course it wouldn't hurt to check, but I can't imagine it not having one. But who knows, they could have just put in the bare minimum of what they needed.

True. It is common practice by OEM builders to maximize their profit. That is why I never go for OEM built.

I was actually going to buy this graphics card in a week or two and I noticed that all of them have "OC" included in their name... So I can safely assume that they are overclocked? Meaning that my PSU won't be powerful enough...

The PSU will still be okay. Graphics cards OC are not as aggressive as processor OC so the incremental power consumption should be minimal... Do not worry about it. Did you visually confirm your PSU have 6PIN PCIe connector?

If I'm not mistaken, MSI products CAN be overclocked, but they don't come OCd, you only get "MSI Afterburner" software. Maybe I'm wrong, anyway - moving on. I'm certain that I have 6PIN connector, however I would like to know why I have 2 of them? 2x6PIN connectors. Is that how it usually is? Here are two pictures that I took

Good for you. It means your PSU can support even graphics card with 2x6PIN connectors or two graphics cards with 1x6PIN connectors. But you must ensure that the total power draw of your system with the graphics card/cards is <500w. You can use this: http://extreme.outervision.com/psucalculatorlite.jsp

That calculator confuses me a bit. I don't have any additional non sense in my XPS 8300... Normal headphones, normal keyboard & mouse (no lights in any of them, nor in my desktop itself). Only one DVD/RW drive and that's about it really. I don't use any special sound cards or blue-rays. If I calculated correctly I am normally using 210/260W with my current card & I would need ~300W if I decided to get 7850...

Then that is just the way it is. It confirms that you do not need to get a new PSU when you get 7850.

Graphics card manufacturer recommends higher PSU wattage because they can not anticipate any possible combination of PC components so they estimate with a good buffer capacity to make sure. But since you know exactly what you have, you can customize the PSU rating based on your current & planned components.
