Hello all

I have just bought this PSU in hopes of it powering my new mid-level gaming PC. However, after some feedback, it seems that this may cause some problems, and I was wondering if I need to make an emergency purchase for a new PSU tomorrow (parts are arriving Wednesday) or if this will work. My other components I have are here: http://pcpartpicker.com/user/skilledman101/saved/1XUY
Here is the PSU:http://www.newegg.com/Product/Product.aspx?Item=N82E16817171038&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=
Thanks

CM PSUs are not known for their high quality, but there is nothing really wrong with using it for that build other than a weak +12V rail(s). It may not be able to handle the card at max demand. If it is on its way, use it and see how it performs. If you can still replace it, go for this one instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371016
It is in that same price range but has a stronger +12V rail(s) and is of slightly better quality. If you have a higher budget, let me know.

Alrighty. PCPartpicker said my build would only draw about 400W, so I hope it will work. Thanks alot.

Edit: Forgot to mention that someone said there would be conflicting power usage problems with the 760. Could you confirm that?

This is not my area of expertise, but TMK, that PSU is completely incompatible with the GTX 760, which requires a +12V rail with 30A. That PSU has 2 +12V rails, neither of which appears to exceed 30A. So yes, you do need to get a new PSU.

Actually, the GTX 760 has a max TDP of 170W: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-760/specifications
That calculates out to about 14.2 amps on the +12V rail. The next most demanding item is the CPU which is a 95W processor. That will draw about 9 amps from the +12V rail. The MB is only about a 35W item (~3 amps). The rest of the +12V devices are tiny unless you add something out of the ordinary.

Skilledman,
Take a look at this list. Your PSU is listed and the review by Hardware Secrets is NOT flattering nor good
http://www.johnnylucky.org/power-supplies/psu-lemon-list.html
http://www.hardwaresecrets.com/article/Cooler-Master-eXtreme-Power-Plus-600-W-Power-Supply-Review/1034/1

The PSU is manufactured by Seventeam, and is not a very reputable build.
SOME of coolermaster's latest high end PSU's are really good, but not neceesarily those in this group.

Recommend the following
XFX Core Edition PRO550W (P1-550S-XXB9) 550W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply
http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013
$69.99 with $10 rebate = $59.99.
Made by Seasonic, 5 year warranty, 80Plus Bronze (That CM isn't even 80Plus rated).

EVGA specifies that the +12V rail must have 30A for their 760.
http://www.evga.com/products/pdf/02G-P4-2761.pdf

I could not find any information on MSI's product page.
http://www.msi.com/product/vga/N760-2GD5-OC.html#/?div=Specification
But I would not expect MSI's standards to be different.

You can go by manufacturer's "recommendations", or you can go by the math and the specs. Your choice.

Alright guys. Thank you all for the help. I think I will just go buy a new one tomorrow. Can someone send me a recommendation for one from Microcenter ~$65?

Clutchc, if you ever come across hard evidence that those manufacturer's specs are incorrect, I'd like to hear about it. I would want to know why they would recommend a higher amperage than needed.

(I thought I just did) But I'll leave you to your opinion.
The manufacturers have no idea what the rest of a user's system consists of. Or the quality or specs of the PSU the user has. They have to assume the worst. Their recommendations are based on the worst case scenario. I imagine there's an attorney or two in the mix too. ;-)
