New i7 System - Power Supply advice?

SpacialKatana · Sep 12, 2014

My new rig is an i7 4770 , Asus Z87 Pro, 16GB Corsair Ram , GTX780 Ti and possibly 2 HDD's.

800w or 1kw recommended? Are Corsair good enuff or get a different PSU?

I won't be doing any overclocking etc.

Thanks.

250W for the graphics card and 80W for the CPU. And with the rest if parts added, a 600W will be enough.

Go with one from Tier 1-2. Here's the list to assist you out.

You need at least 600W and a good quality npower supply - from tiers 1, 2a or 2b of http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html
eg Seasonic M12II 620 $75 - http://www.newegg.com/Product/Product.aspx?Item=N82E16817151095

The good Corsair aren't as good and cost more.

Yep he's got it for sure. Quality on the cheap.

Yuck - tier 3

spentshells · Sep 12, 2014

Silly money wasters. JK. But seriously 600 watts is way more than enough.

LukaBoki · Sep 12, 2014

If you want to have just enough power for your system,XFX Core 650W,Seasonic M12II 620W/650W.

If you want to have a bit more,then XFX Core 750W,EVGA SuperNOVA G2 750W,Seasonic M12II 750W,Corsair AX760i or Cooler Master V750.

If you want more than enough power for your system,XFX Core 850W,EVGA SuperNOVA G2 850,Seasonic M12II 850W or Corsair AX850.

If you want to SLI in the future or have extreme overkill for your system,Seasonic X 1050W,EVGA SuperNOVA G2 1000W or Cooler Master V1000 1000W.

All the best.

Thanks for linking the list guys, I'm new on site as you can see ;] Never had any problems building, just picking the right reactor for the system ie picking a good make.

Thanks again.

spentshells · Sep 12, 2014

Wow thats out of control. 600 is plenty for that setup, my tier 3 (lol) psu deals with a much higher power draw than that system will while at full load, without breaking a sweat. The seasonic psu linked above is a really great deal and frankly the best option that has been offered.

No worries. And welcome to the forum buddy. All the best.

LukaBoki · Sep 12, 2014

No problems,mate.
Make sure to choose a solution.

SpacialKatana · Sep 12, 2014

LukaBoki :

How about this? I couldn't see AX in the list, but it is a platinum speced PSU.

Future proofing is good, I may add another GTX780 Ti , or 2 other cards in future

lightcloud · Sep 12, 2014

Yes that's in the PSU tier list I listed. It is a Tier 1 PSU and you will be fine.

And if you plan to do a GTX780Ti SLI then that will be great.

spentshells · Sep 12, 2014

You could run 2 of em on that.

SpacialKatana · Sep 12, 2014

Excellent they can get it to me by tomorrow.

Thanks for your time (all of you).

LukaBoki · Sep 12, 2014

SpacialKatana :

950W is recommended for 2xGTX 780 Ti.
I am a kind of person that likes having more power,just to be on the safe side.
I would recommend the EVGA SuperNOVA G2 1000W as your PSU if you want to add another GTX 780 Ti.

spentshells · Sep 12, 2014

Its more than enough.

These two are great and within your budget.

http://uk.pcpartpicker.com/part/evga-power-supply-120g21000xr

Or

http://uk.pcpartpicker.com/part/xfx-power-supply-p1850bbefx

Both are Tier 1.

SpacialKatana · Sep 12, 2014

I'm leaning towards this one:-

http://www.amazon.co.uk/XFX-Black-Edition-Fully-Modular-Supply/dp/B00B88Z0LM/ref=sr_1_1?s=computers&ie=UTF8&qid=1410524588&sr=1-1&keywords=XFX+P1-850B-BEFX

It's one Joeteoh99 recommends, and with the chart spentshells linked, I think it'll handle 2 GTX780's in the future. It's a bit cheaper (£114) and I can get it tomorrow

spentshells · Sep 12, 2014

Nice choice.

lightcloud · Sep 12, 2014

SpacialKatana :

Yes you will be fine, it is also another Tier 1 PSU. All the best mate.

SpacialKatana · Sep 12, 2014

Done and done. Thanks guys, clear concise posting and not being a nub myself made the choice very easy.

Kudos to Joeteoh99 & spentshells.

SpacialKatana :

I would get a 750W Seasonic or XFX power supply to allow for more upgrade space in the future.
