I am building my brother a PC and im looking at power supplies at this point. His rig will be pretty much the same as mine, Single 970 or 980ti, 4690K x5 thermaltake Riing 12 fans, 500GB SSD More then likely NO overclocking he is REALLY new to anything computer related. With out breaking the bank what do you recommend. Id like to stay under $100 for a PSU

As said either an EVGA SuperNova G2 or a Corsair RMx.
Wattage depends on which video cards and how many.

550 watts for a single GTX 970/980/980 Ti
650 watts for dual GTX 970
750 watts for dual GTX 980/GTX 980 Ti.

Keep in mind there's about a 100W difference between the 970 and 980ti. I'd look for no less than 500'ish for a 970 system and 600'ish for the 980ti. But no overclocking, really? I'd add another 50 to 100 to make comfortable capacity for some overclocking.

You dont need that much a good 400 watt is more then enough for GTX 970 and a good 500 watt for a GTX 980 Ti.
And that thread has not been updated in ages.

He is really really idiotic when it comes to PC's. Were talking hes about 35 and has never owned a PC so im 100% sure Hes not going to overclock period. I dont mind buying a 650w for wiggle room but hes been a console gamer all his life so first PC im sure he wont even know how to turn it on lol

650 watts is overkill for anything short of GTX 970 SLI then.

Maybe, but It's so trivial to overclock an nvidia gpu with afterburner, i'm assuming he's going to game on it, with a 970 there'd be some serious incentive (10+ fps) to bump gpu clocks up and to setup a fan curve (the clock sliders are right next to the fan controls). Sure, cpu overclocking is less approachable.

You might want to nail down the gpu first: 970 or 980ti?
1080p or 1920x1200 --> 970
1440p --> 980ti

I wish it were more up to date, the models it shows are still good models.

Personally, I prefer a little breathing room for a few reasons.

- room for overclocking
- operate cooler and quieter when not at full capacity
- degrade less quickly when not running at full capacity
- can tolerate some degradation after years of use and still cut it
- peace of mind

Non-overclocked 980ti 275w + i5 100w + mobo 100w + cooling fans and such. 500w is definitely too close for my comfort.

Those are absolute max power draws and a PC will never be loaded at 100% which means real life numbers are nowhere near that.
A full on gaming system with a full water setup a bunch of pumps HDD´s fans and everything else you have and overclocks on CPU GPU and RAM and the whole system wont draw more then 300-400 watts at the most.

The system is only going to draw more if you BIOS volt mod your video cards or you have an AMD FX CPU or Intel X79/X99 CPU or if you have more then one video card.

Here you should watch these videos and you will see that power draws are far lower then you think they are

A good 550 watts PSU is more then enough for almost any gaming system out there with a single video card and this has been proven and confirmed an untold number of times by an untold amount of people and users.
Anyone that claims you need more either dont know what they are talking about or they are spredning misinfomation either on purpose or because they are misinformed.

I'm sorry, I'm not ignorant and I'm not lying for some vague malicious purpose, nor have i suggested a 1000w power supply. What i said is this...

> 500'ish for a 970 system and 600'ish for the 980ti. But no overclocking, really? I'd add another 50

If you can do math, that works out to
500-600w for a single 970 --> 550w
600-700 for a single 980ti --> 650w
The upper end of those ranges to accommodate overclocking and some degradation of the psu over time.

What you said is this...

> 550 watts for a single GTX 970/980/980 Ti

A strikingly similar number. The biggest difference is you don't acknowledge the higher power requirements of the 980ti. Go look at the spec sheets.

> A good 550 watts PSU is more then enough for almost any gaming system out there with a single video card

I'm pretty sure that wouldn't be more than enough for my x99 + 980ti rig. I don't have a kill-a-watt, but I'm going to get one to see just how much power my system is pulling?

I did not say you where ignorant or lying so sory if you took it that way it was not meant as such nor towards you.
As for your system you have an X99 CPU which is a power hog when overclocked just as i already stated.

Also note that numbers you get from the kill a watt is not what the system is actually using as you have to take the rated efficiency of your PSU off the numbers you get from the kill a watt.
If you have an 80 plus gold rated PSU you need to take 10% off and so on.

Its not bad at all but its not all that great either and i would get a great 550/650 watt over a decent 750 watt any day of the week.
Thats just me but there is nothing wrong with the B2 if you want to go with that.

The FSP Hydro G is not a bad option at all.
Just keep forgetting about it.
