  3. Can I use a 460w PSU for a HD 7950?
2 years ago#1
I bought a 7850 but now regret it and want a 7950. However I'm on budget and am hoping I can still use the same power supply. It only has one 6 pin connector cable though and the 7950 needs two. However my 7850 came with a 2 molex to one 6 pin adapter cable. Can I use that along with the PSU's one 6 pin connector to power both 6 pin ports on the 7950?

That's a pretty crappy PSU you've got there, but it should work. What else do you have going on in your computer? The reason I ask is because your PSU will simply burn and die if you try to draw more than 420W from it. If you have a regular setup with a normal CPU, single GPU, a hard drive or two, no overclocking going on, you'll never come close to drawing 420W, so while I don't recommend using this PSU for anything but the most basic of office computers, it should work fine... just make a plan to replace it at some point sooner than later.

My old build has a Cooler Master.
Such a POS PSU... Loud as hell as well.

To be fair, Cooler Master has always had a small number of good PSUs, and they've been listening to customers and press experts in the last couple of years and made substantial improvements. While they continue to sell their low-end series (Extreme Power Plus, Elite), they appear to be working hard at improving their offerings.

It'll work within spec up to 400w, apparently.

It won't explode or anything, but I'd suggest replacing it anyway.

I think you should stick with you're 7850 until you have enough money to buy maybe one of the new amd cards and a better cpu.
