Is 450 power supply enough for???

Is 450w supply enough for i5 4440 , gtx 1060 3gb, ram 8gb,gaming mouse and keyboard, 7.2rpm 1 tb hard drive

 

[Trafalgar747]

Yes it should be, however a 500w or greater would be recommended.

I would go with at least a 500w PSU for your rig, EVGA makes a excellent 80+ gold 550w PSU: http://www.evga.com/Products/Product.aspx?pn=220-G2-0550-Y1

Hello!

Yes, with your current specs, you actually only need a 370W PSU, that is including 3 case fans, two pulling air in and one pushing out, so yes that is enough I expect

I agree 100% 😀

Well his system under max load should be 200W. Gaming load should be around 175W. So I don't know why you all are over exaggerating so much.

PSUs generally last a long time, so it's better to go with more wattage for upgradability in the future.

 

[Phoenix864]

Also, higher wattage PSUs are generally higher quality.

That's why I have a Corsair Platinum HX850i running a i5 4690K OC, GTX 960 OC, MSI Z97 PC Mate and 2 1 TB HDD's...completely overkill but still...future-proofing! 😀

No. A generalized statement like that has zero support and is not true.

Everyone always says this, but let's look at the facts. For the past many years now, power consumption is decreasing with each iteration of new hardware. So why would anybody need to future-proof? It's more of a good excuse to get a high-wattage power supply than an actually smart thing to do. Looking statistically, only a puny portion of people run multiple GPUs; and a 450W power supply could easily power two GTX 1060s anyway (not that the GTX 1060 supports SLI to begin with); a 450W power supply coiuld actually work fine with two GTX 1080 FE cards that are not overclocked along with a non-overclocked CPU.

That also means increased waste heat due to reduced efficiency compared to, say, a 450W power supply running those same specs. Increased waste heat reduces the lifespan of capacitors. Not that in your case in matters, but you literally spent money you didn't need to spend, when in the end you could have just gotten a better GPU.

At least for EVGA, more watts = better components: http://www.evga.com/Products/Product.aspx?pn=100-W1-0500-KR
550w gets Japanese connectors, bigger fans, longer warranty, ECO mode power switch, and higher power efficiency.

That has nothing to do with "more watts" it's a completely different power supply built upon an entirely different platform targeted at an entirely different pool of consumers, being enthusiasts vs budget consumers.

I used to have a 500W PSU running my rig and as soon as i put my HX850i in, the performance of everything increased slightly. I plan on getting better components soon anyway and also I have a Corsair Air 540 case so additional heat doesn't matter because its on the other half of the case, not effecting the mobo temps. Furthermore, the PSU stays at 38C under load and the fan on the PSU never spins...literally never. I think it was a good purchase, not a waste.

PSUs don't affect performance; that is just a placebo effect.

 

[Phoenix864]

Not worth pushing my point. I do lots of OCing, and my 1080 Hybrid sucks power. Using a power calculator I need about 650w, but I plan to sli my 1080, so I am running a 850 GQ. But maby for the OP 400w is fine. Would not go under, as the 1060 recommended PSU is 400w min.

Power calculators do not give an accurate representation of power. They are huge overexaggerators, some of the worst being Newegg's and ones you'd find on the website or of company (because they obviously want you to spend more money!). Outervision can also be poor. In addition, Nvidias recommendations are silly, because it only takes into account the GPU, not the whole system, and something like a Logisys 400W PSU clearly could not power an FX 9590 and GTX 1060, making Nvidia's recommendation A CPU, RAM, GPU - all of that has a clock rate. It does an instruction per cycle. The PSU does not affect this, it does not speed up these cycles - everything still happens sequentially and the same, no matter what the power supply is.

The reference GTX 1080 is around 150W; this has been measured. Overclocking to that max limit of 2100Mhz these cards have, and taking into account that they are aftermarket, would merit somewhere around 200-215W most likely.
