Sorry I mean PSU!!!

Well there's a few PSU calc sites out there. Here are some quick results:

My files are in flux during my rebuild but another thread likes an extreme.outervision page that apparently mimic's CM.

These should all be accurate.

Get a quality 550W gold rated PSU from either of Seasonic, EVGA, Corsair.

Your PC will not use much power

Yes, a Quality PSU. I prefer Seasonic, but that's just me. The MSI 1050 TI I looked at required a 300W PSU, but I would rather get something a bit beefier in case you want to upgrade at some point. 500-550W seems like a good starting point.

Not the best PSU by a long shot from Seasonic, but it's fully modular and inexpensive at $40 AR. It would be perfectly fine for your needs.

This+. I have a SeaSonic 550w PSU and never had any issues with it and it is five years old.

I calculated using both cooler master outer vision and power supply caculator and to my surprise they both gave me two answers.. outer vision shows results us 318watts and power supply calculator shows us 377 watts... what can I do?? I am pretty much confused right now!!!

 

[HisEvilness]

EVGA and Seasonic give 10-year warranty on a good PSU, as far as the results take the highest number and add 100 wats so you can upgrade the GPU down the road. In your cause around either a 450 or 500 watt PSU would be fine.

There's nothing to be confused about. It doesn't hurt a thing to get a higher wattage PS than you technically need. What you don't want to do is get the bare minimum.

thats because those online calculator are not 100% accurate. everyone of those gives ~100+ watts more than my actual consumption via a killAwatt.

you have a ~65watt CPU w/75 watt graphics card. add 6 watts for the chipset, 4 watts for each stick of RAM, 10 watts for that spinner (~2-3x more to start up that HD though boot) and 10 watts for each fan.

you're actual power consumption is floating just above 200 watts - under heavy load.

i've seen people use a pico power bricks for that. unless you're looking at a much much better graphics card in the near future a corsair CX/CS 430/450 would be appropriate.

 

[Rayman30]

I would get enough wattage to support a nice dGPU, as in the future when you want to upgrade, you would have to buy a new PSU and Video Card. I would avoid this pit fall and get at least a 650W PSU, such as this eVGA 650 G3.

Agreed. You can get a plat or titanium rated one if you want to but 550W will be perfect. Room for upgrades should you choose to.

 

[Rifter]

a 400W will be fine, grab a 500-550 if you want some breathing room.

 

[Oyeve]

My system is similar to yours but I have 5 ssd drives and br drive 1080gtx and 6 rgb fans. I opted for an 850w corsair for the overhead.

@alexy

What is your budget for a PSU?

edit: in my opinion, here's a list you should be looking at:

https://pcpartpicker.com/products/power-supply/#m=11,14,71&sort=price&e=4

or, if you trust Rosewill (which maybe you should)

https://pcpartpicker.com/products/power-supply/#m=11,14,51,71&sort=price&e=4

That Corsair TX550M is looking pretty good for only $55. It's Gold-rated and gives you room to grow. Not sure if it's worth stepping down to a 500W just to get that Rosewill Lepton 500W unit for $2 less. I wouldn't bother with it.

If you want a fully-modular unit, check out this list (all manufacturers shown):

https://pcpartpicker.com/products/power-supply/#sort=price&e=4

You'll see a Coolermaster 650W unit for $61.

and 10 watts for each fan.

Fans are usually no more than 1.5W each, unless a tiny high RPM fan in a 1U server or video card, then "maybe" double that.

i'm sure we can cherry pick fans and their power use; high static pressure fans use more . . . 10 watts will cover all the bases.

 

[mindless1]

^ Sure, you could just say all CPUs are 400W and all video cards 80W to cover all bases too, but it wouldn't be remotely close to the truth.

Show me a fan that uses 10W where anyone will need more than one of them unless they're shooting for an overclocking record? Maybe in some case where someone shoehorned a gaming card into a very small form factor system so they're stuck using 80mm or smaller fans, not at all the typical system.

The average gaming system needs no more than 6W total worth of fans. Realize that what is on the fan label is the stall current, not the average current at 12V, and these days not even close to the throttled RPM current many motherboards or aftermarket fan controllers support.

On the other hand, it is better to overshoot needed capacity than undershoot and we're not talking about that many watts difference, but these things can be measured.

An estimate should strive to be as accurate as reasonably possible then if you want a margin on top of that, you add that on top of the most accurate estimate possible.
