Ultra 730W PSU Enough?

GPU: go for a ati 7870 tahiti LE jokercard (2GB) very fast, best bang for buck.

PSU is good enough, I have a 600wat zalman psu, does the job also.

The PSU will only be good enough if it is a decent quality.

It seems to have a good rating across the 12v rail but all the information i can find on it says that Ultra uses bad OEM's.

Based on that i don't think i could recommend it, get a decent PSU from a good brand such as seasonic, xfx, antec etc

OK I should get a new PSU then but should the gtx650 TI enough for 1366x768 resolution gaming or I should get the 7850?

The 7850 is two tiers higher than the gtx650 ti so i would get the 7850 if you can.

And make sure the new PSU is from a reputable manufacturer.

Thanks.-

the 650Ti should be great for 768 gaming, but I've seen the 7850 for around $150 with rebates, I would def spring for it at that price if you can get it ~$150-160. The problem would be that at such a low resolution, the game will be more CPU bottle necked, so you have to turn the details up higher to overcome that and force the GPU to do more work.

If you are running the game without VSYNC and you use a program like Afterburner to monitor temps and GPU usage, if you notice the GPU not being utilized more than 90% or so, that's more than likely a CPU bottleneck, so you should turn the details up or increase the resolution (bigger monitor).

I like the 650 Ti for $129 or less, which I have seen it, but anything closer to the $150 price, and you should def consider the Radeon.

The Ultra PSUs are ok, but I would still consider them a lower grade PSU. Even so, a single GPU should work fine on it. As long as it has 35 to 40 amps on the 12V rail, it should run one GPU fine. You can look on the sticker to see what it rates the +12V at...

You can find some REALLY good rebates on Corsair 600-650W CX series PSUs right now and they would be MORE than enough for a single graphics card, upto even the 670, 680, and 7900 series. Antec has also had some good rebates right now.

Most modern GPUs will run fine on a good quality 600W PSU, and the only time you need more than that is with massive overclocking or a SLi/crossfire setup.

12V rail is 45 Amps in the sticker of the PSU , I think I will go with the 7850  , and my phenom x4 965 I think it wont be a bottleneck for the GPU but just in case I think I can overclock a little with the free multiplier.

Yea i did find that it had a reasonalbe amperage on the +12v my gripe was mostly that everything i have read points to them using bad components, this means it's more likely prone to failure.

If you have the funds, dump the Ultra PSU and invest in a nice Corsair unit that will last you for at least 7 years (warranty period on some of the units).

I will change my PSU also, what do you think about these two?:

and I think I will go with this 7850:

The CX600 is a good unit, with plenty of headroom to upgrade. Might even be enough for a second 7850, but it would be pushing it.
