Validating PSU choice

[Moliat]

TL;DR: Is the below PSU sufficient to comfortably power the below intended build?

 

Hello,

 

I'm building a new desktop, been using a Schenker XMG P702 until now, so I'm unfamiliar with building a desktop in terms of choosing parts.

In that regard I need help figuring out of my chosen PSU is sufficient for the intended build.

 

I'm also very open to general advice / input regarding the build. Intended for gaming on 1440p on a 60 Hz monitor (U2515H).

 

Also trying to decide between a GTX 980 Ti (G1 Gaming) or an AMD Fury X.

 

First-time poster here, so I apologise in advance if I do not adhere by posting rules or best practices.

 

/ TL;DR

 

 

PSU: Cooler Master G750M 750W

That CM PSU has Capxon and Jun Fu capacitors, a fan that is not loud on lower loads but extra loud on higher, mediocre soldering job etc.

I would not recommend that for a PC like that. 

 

Is a Seasonic S12G-650W an option?

[Moliat]

Thank you for your response!

 

I can't find the Seasonic S12G on any norwegian stores' website, so I'm afraid that seems to not be an option.

 

The noise level of the CM G750M is not a problem. Mediocre build quality that impacts longevity (and potentially risks the other components, if that's a possibility) is however a concern, if that's the case.

Have a look at the EVGA B2 750W.

I couldn't find the EVGA B2 750W, but did however find the EVGA G2 750W. How's that?

Also, is 750W going to cut it for the 980 Ti G1 Gaming, factoring in potential future over clocking, or will 850W be necessary?

Thank you both for your input!

any black seasonic

or xfx psu would be good

rosewill capstones are really good to

Cooler Master GM is fine... http://www.techpowerup.com/reviews/CoolerMaster/G550M/11.html

Techpowerup says one, but hardocp and jonnyguru say otherwise...

[Moliat]

Is 750W enough for my intended system?

 

How's the EVGA Supersonic G2 750W compared to the G750M, considering it costs twice as much (in Norway)?

 

Should I replace/upgrade my G750M?

 

I appreciate all the help!

If you can afford the EVGA G2 750W then I would say it is one of the best power supplies around for the price/performance.

 

This is the B2 version:

 

http://www.prisjakt.no/product.php?p=2738799

 

It doesn't have semi fanless mode like the G2 and it is semi modular instead of fully modular. It is still a very good psu for the money as you can see in the review I posted above.

Ah, thank you!

 

Factoring in shipping costs from the 2 websites that offer the B2, I can get a G2 for the same price, for both the 750W and 850W model.

I can always afford the upgrade if it's necessary. From what I understand based on the helpful posts here, the G750M would be sub-par quality compared to the rest of the build.

 

The question then is if getting a 850W G2 would be more prudent (considering the higher price) than the 750W G2.

The 750W G2 is plenty for your system even for SLI.

If you already have the g750m do not change it, it is good enough to stay in. I thought you were buying...

Understood. Thanks! Even the G750M? (I don't know how efficiency or quality impacts the PSU's performance and longevity under high loads).

I already have the G750M, but can return it for a full refund, so that's irrelevant to the decision.

[191x7]

Maybe Fractal Design Edison M? Are they awailable to you?

The G750M will work fine in your system if you already have it. Will it cost you any money to return it ? i.e postage ? as that would add to the cost if you went for the EVGA.

They are available at the link above, but they are more expensive than the EVGA G2.

0 cost of returning, and full refund.

 

I got the G750M for about USD $77.

Instead I can return that and get the EVGA G2 750W for $154, or the 850W for $167 (i.e. practically no cost of upgrading to 850W if I'm first getting the EVGA G2).

You are aware that a decent 550-650W PSU would power that PC with no problems whatsoever (even if you're aiming for two GTX 980)?

With no upgrades a good 450-500-520W would do too. But I mean really good.

Most 550W power supplies won't have enough native pci-e connectors for SLI. A 750W means that the psu isn't running near maximum load all the time if He adds a 2nd GTX 980 ti.

No, I'm afraid not (and I understand that's frustrating). I am completely clueless with regards to the wattage I need my PSU to supply; however, the reported peak consumption of 360W of the 980 Ti G1 Gaming, in addition to the 4790k and other components, led me to question the suitability of a 750W. Especially one of questionable quality.

A store representative I spoke with today recommended an 850W PSU over a 750W PSU "to err on the safe side and for additional overhead". That might just be up-sale however, so I take his statement with a grain of salt.

So the bottom line here, as I understand it, is that 750W is sufficient for the build (even considering the 980 Ti G1 Gaming's 360W peaks), but that I should replace the G750M with an EVGA G2 750 (or 850) due to superior quality?

 

Thanks again for all the help!

The EVGA G2 750W gives you expansion room for a 2nd 980 ti in the future. You don't need to go as high as the 850W.

 

If you are certain that you won't SLI then you could go with something like an Antec High Current Gamer 520W.

Depends on the price gap. G750M is still a great PSU but whether it's worth it to step up to the G2 would depend on how much you'd be willing to shell out. 

 

If you're looking for more wattage but still good quality there's always something like the EVGA 850B2.

The EVGA G2 750W can even run SLI 980 Ti G1 Gaming, with a peak load of 360W? To me that sounds like 2x 360 = 720W from the GPUs alone under peak load. Admittedly this calculation is probably completely erroneous...

 

I don't plan on getting SLI in the near future, but I'd like the opportunity.

I paid $77 for the G750M. Upgrading from that to the EVGA G2 750W costs an additional $77 ($154 total). Further upgrading from the G2 750W to the G2 850W only costs an additional $13.

The big leap is the doubling of price by going from the G750M to the EVGA G2 750W / 850W.

 

I'm willing to pay the money if it's necessary, i.e. if the EVGA G2 will perform markedly better than the G750M, provide less risk for the other components, and/or last significantly longer. At the end of the day I won't cheap out on the PSU, if settling for the G750M rather than paying twice as much for the EVGA G2 is indeed cheaping out. If making that leap won't markedly impact performance, longevity, or the risk to the other PC components, then the upgrade doesn't seem economically rational.
