New Computer

[Chris]

I feel the need to share, this thing is a beast.

Cooler Master HAF X RC-942
Intel Core i7-3770k 3.5GHz
ASUS Sabertooth Z77
Kingston HyperX 16GB DDR3 1600
Gigabyte Radeon HD 7950 3GB
Rosewill Lightning-1300

And then I added an after stock Zalman fan and there's an SSD, an HDD and an optical drive, but I listed the important stuff.

I'm so happy. Luckily the internet saved me from dropping another $600 when the new GTX 690 was out of stock everywhere, haha.

Do you really need a 1300 W PSU? That system will probably require less than half of that at maximum load. I guess you'll want to overclock.

Anyway, nice beast. I will be building a similar one soon, although less overkill.

I would probably avoid getting a rosewill anything. It's like getting a dollar store brand. It may work, but I sure wouldn't trust it with my expensive new components.

I had 850W and it wouldn't boot, so I figured instead of purchasing 1000W and running the risk of paying another restock, might as well get the 1300W.

And really Deadcell? I can't say I'm too familiar with PSU brands myself, was going to go with the 1200W Cooler Master but I liked the semi-modular aspect of this and the reviews seemed good. I will keep that in mind though, thanks for your input, perhaps I will look to replace it.

Definitely a best of a machine but I agree that the PSU is overkill and you typically need to stay away from Rosewill.

Rosewill is Newegg's in house brand of products. Their products are always made by some other company and in many cases they use many companies for similar products. That PSU is actually made by Super Flower which is fortunate for you because this is a very solid model from Super Flower.

But again, beast of a build.

[Chris]

Thank you for your responses gentleman. I must admit, this is my first build, and while I keep up to date on new chipsets, I rarely read or keep up on PSUs, so it has been a bit foreign to me. What would your recommendations have been on wattage, and would you suggest that I replace it with that wattage at this point now that everything is put together and operational?

More importantly, how much more should I expect my power bill to be, haha.

[Viper]

PSU's are often overlooked because they don't get the major coverage of a new CPU, GPU, motherboard, HDD/SDD or even RAM does in the media. But it's actually one of the most crucial components and doesn't get the respect it deserves. I admit I didn't give it enough due diligence in my old 2006 build but I've since learned better.


The one you have will be fine. Newegg was lucky to get a good PSU for that model.

http://www.jonnyguru.com is where you want to go to learn what to look for in a PSU. It also includes a very thorough database on PSU's and a PSU calculator to quantify just how much power you will actually need.

Another good site for psu info/reviews http://www.hardwaresecrets.com/page/power/15/1

[Chris]

Thank you both very much, I will be sure not to make the mistake of undervaluing the PSU the next time I build.

[Luis]

According to a calculator I just tried, my new system wouldn't require more than 380 W at full load. And I was thinking a 550 W PSU wouldn't be enough.

Are you sure a 1000 W one won't be starting your system up?

[Viper]

What brand and model was the 850 watt PSU, Chris?

[Dralor]

It could be his PSU just died. I replaced my old 500 watt with a 750 watt Thermaltake modular one when that happened to me a few months back.

[Chris]

I made a mistake when I said 850, it was 750, and it was Zephyr

I thought it could've been a bad PSU too, but I certainly didn't want to send it back, wait for a new one, only to find out that it wasn't enough. And like I said, I was ignorant to the necessary wattage, something I won't be taking lightly again.

[D3adcell]

I have a similar build to yours, but 8GB DDR3 instead of 16 and a 2GB video card. Mine is all running on a 650W PSU. However if I did want to add a new card to crossfire I would need more wattage. Your likely didn't need that much, but at the same time if you ever want to add extra fans, optical drives, or another video card you should be safe.

Something odd about that PSU. I'm reading that it's supposed to have 4 12v rails @ 19 amps each but the actual PSU is only showing 2 12v rails at @ 30 amps each. While the totals aren't far off, it's not good to have such a blatant discrepancy. Especially on the 12v rails.

I'm also noting a lot of people on Newegg are saying their PSU was dead on arrival which sounds like the problem you had. Even saw a few people had 2 DOA's from this model.

[Dralor]

Not only that but it clams 80plus bronze then another pic is just 80 plus

This is the best index of PSU reviews on the internet.

Overkill on the motherboard and could have chosen another PSU. That system is going to pull 400-450W
max, at full bore with an unrealistic load, uphill, bothways.

XFX and corsair make a good number of seasonic powered PSUs.
