Will 650w PSU handle a 980 ti and i5 6600k gaming setup?

Edge91493 · Jan 1, 2016

My Asus 980 Ti Matrix GPU is coming next week. I am wondering if a 650w PSU can handle this gaming setup. I've tried using PSU calculators online and they have different results.

PSU: EVGA Supernova NEXG 650w

Rest of setup are:

CPU: Intel i5 6600k @ 4.5ghz/1.25v
COOLER: Cooler Master Hyper D92
GPU: Asus 980 Ti Matrix Platinum Edition
MOBO: MSI Z170A Gaming M5
RAM: G. Skill Ripjaws V Series 16g (2x8) DDR4 2666
HDD: Western Digital Caviar 750gb 7200rpm
SSD: Samsung 950 Pro
CASE: Fractal Design Define R5
FANS: Fractal Design Dynamic GP14 140mm x 3
PCIe ADD-ON: TP-LINK Archer T9E Wireless Adapter

It will, but I wouldn't use the NEX. I would get the B2, G2, or GS series.

BadActor :

The PSU was the first thing I bought, together with the MOBO and CPU. I only based my decision on the 80PLUS rating and I thought gold was enough (very stupid of me). I only saw that tier list a few weeks after. I so so so so regret my purchase as I saw that the G2, which is only $10 more expensive than the G1, is a first-tier PSU *sigh*. Anyways, I can't turn back time so I'm stuck with this. I could return it but not my first option because it's a hassle (I'm from Hawaii). What could go wrong using this one?

If you already have it then use it you have enough power for that PC.

Zerk2012 :

Well. I don't have the GPU and SSD yet so I can't test it now. It's doing fine with the rest of the setup + Asus 560Ti card though. If I try to test it and the PSU can't handle it, will it do any damage to the other components?

Zerk2012 :

I concur. Your PC should use under 500W at full load. Mines similar and pulls 475W Max from the wall and at 90% efficiency 427 DC Watts.

Edge91493 :

Your power supply can handle it.
Adding a SSD don't even count

cliffro :

Do you have the same PSU tier and wattage?

Edge91493 · Jan 1, 2016

Hmmm. Now I'm just worried about the tier then. What do you guys think?

cliffro · Jan 1, 2016

Different wattage, mines an EVGA 850 G2. But that's irrelevant. Based on my similar(not exact) hardware and a known 90% efficiency with my PSU at the wattage reported by my Kill-a-Watt my parts are pulling 427.5 DC watts(475w AC). Your PC should require similar wattage. It may not be 427 like mine, but it's going to be close. And a 650 watt psu should work just fine.

I posted this from my phone so ignore my run on sentences.

I found a review of the PSU on [H]ardOCP.

The Bottom Line

The EVGA NEX650G is an example of a "good enough" power supply from a company that may be finding itself a bit out of its depth in this market. Clearly, the NEX650G is "good enough" as it has a good build quality, decent voltage regulation, very good efficiency (though it misses it's 80 Plus claimed efficiency level), very good Transient Load Test results, and good DC output quality but it does get a bit louder than we would expect from such a product today. In sum, it is good enough. Where this unit seems to be from a brand that might be out of its depth is when we get to some of the design choices that serve no real function and the support that comes with this unit in the way of documentation and warranty.

His major complaints in the summary were documentation and warranty. He says it missed the Gold Efficiency, it missed by .8% @ 100% load.

Overall I wish it was reviewed on JonnyGuru, if they say it's good, it's good. Or bad, depending on the outcome that is.

There's actually a review by JonnyGuro. Here's the link: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=442. I guess this will do then. Thank you.
