Not at all. The 980Ti is about 250W of power draw on stress. Two of those is 500W, plus the CPU can make around 625W, and the rest of the system so you're looking at a 710W maximum draw build.
 
I tend to always ignore "recommended system wattage" for GPU. They assume you have an absolute crap PSU and like 10 hard drives, 2 CPUs. I prefer to do the mathematics myself, as 1300W is totally misleading and could power 4-way SLI 980Ti.

1. Does it have enough amps?
2. Does it have enough connectors?
3. How is the build quality?
4. Does it have enough watts?



Amps on the +12v are the single most important aspect when determining "does it have enough power?" I would put wattage as the 4th most important thing within reason. A 1000w psu with a single 6pin connector is not going to run 2 of anything. A 1000w psu with 35 amps on the +12v is also not going to run 2 of anything. These units exist.
 
Actually I've been running a ''Non-Haswell compatible'' power supply for over a year now. Atleast I've never found confirmation if the Antec HCG-620w is fully Haswell compatible or not. I never actually even thought about disabling the C6/C7 power states. Even then I haven't really heard what effect it really has and if it is necessary. Remember a post of some guy saying it is only a temporary solution when disabling those power states.

I guess I'll disable them? But either way still not sure if mine is Haswell compatible. There is no clear answer it seems. It is something I'm genuinely lacking knowledge of.
 
620W NON MODULAR IS NOT.

Modular series is:

Antec
According to Antec, the following units are "fully compatible" with Haswell:

EarthWatts Green: EA-650 Green
EarthWatts Platinum: EA-450, EA-550, EA-650
High Current Game: HCG-750, HCG-900
High Current Gamer M: HCG-520M, HCG-620M, HCG-750M, HCG-850M
High Current Pro: HCP-750, HCP-850, HCP-1200
High Current Pro Platinum: HCP-1000 Platinum, HCP-850 Platinum (OC link), HCP-1000 Platinum (OC link), HCP-1300 Platinum (OC link)
NeoEco C: Neo Eco 620C
Signature: SG-650, SG-850
TruePower Gold: TP-550G, TP-650G
TruePower New: TP-550, TP-650, TP-750, TP750 Blue
TruePower Quattro: TPQ-850, TPQ-1000, TPQ-1200, TPQ-1200 OC
VP: VP550P V2, VP650P V2, VP650PM
VP F: VP550 F, VP630 F
 


Well yeah, I know all that already but I only recommend quality power supplies. You're not going to find a quality 1000W power supply with only 500W on the 12V rail. It's safe to assume that if the power supply is labeled at 750W, there's going to be about 700-750W on that 12V rail.And quality units come with a surplus of connectors.

I think you're missing the point of what I said. The first thing you need to do is calculate the wattage. Once you calculate wattage, then you fine a power supply with your 1, 2, 3, and 4.

Point be told, the quality power supplies all have a good amount of amps on the rails, and won't have 35A on a 1000W unit. Those would generally be really old or really junky units, which aren't even recommended ever.
 


amps = watts x volts. unless the psu is a split rail design, and those still have a total amp rating commensurate with their total output in watts, there is no difference between the two things. take your standard continuous 750 watt psu. 740 - 744 watts on the +12V, 120 - 125 watts on the +3.3V and +5V and 6 watts/15 watts on the =12V/+5Vsb rails respectively. 62A x 12V = 744 watts output. watts/amps are directly linked. you can't have enough watts without having enough amps. with psus that have OCP in the form of multi/split rails the total amount of current (amps) is sectioned off with current caps on each set of cable/connectors. as far as power delivery this is mostly an issue on multi rail psus in the 600-650 watt range where you'd reasonably expect to be able to run a system with a crazy high draw cpu or gpu and the rails may have a 18A -20A limit on something in the <700 watt range. as for not finding a 1000 watt with 35A, you're right there, because whatever the label calls it, a psu with 35A on the +12V is a 450 watt psu as far as powering modern day computers. you do have some high end 850 - 1000 watt units with 4 rail OCP that each have a limit of 40A (Antec's HCP platinum units).

 


wasn't so much directed at you, more so it was a general reply talking about watt/amps based on CTurbo's post you quoted. CTurbo's separating watts and amps can easily be mistaken for them not being in direct correlation, I've seen it many times over the years. :)

 
Yeah but we're not talking about watts on an individual rail, we're talking about rated wattage of the power supply. Having 20A on the 12V rail is the same as saying 240W on the 12V rail, but if the PSU is labeled as 300W, it's not the same.
 


okay, the way this is worded I have no idea what it means.

 
New contender for the world's worst power supply: Hercules 500W. http://www.jonnyguru.com/modules.php?name=NDReviews&file=print&reid=324

Well, old contender, but just saw it for the first time.
 
That's basically what a double-cheese burger is as mcdonalds...
It looks huge in pictures, but when you open up the box, there's a small burger that looks like one small patty...
Not that I would know from personal eating experience, I just saw my friend order two, take one out, and it was puny.
 


Thanks, I've turned the C6/C7 states off. For what It's worth.

I was mostly referring to the cheap models that can't put out their labeled wattage or the older models that may really be 500w, but only 300w of that is on the +12v
