Is my 500w psu enough for i7 6700k and gtx 1070?

I've already purchased everything for this build except for the CPU and GPU and I want to make sure I haven't cut my self short on power. If it's not enough I've considered the i5 6600k to replace the i7. http://pcpartpicker.com/list/4cgfhq
Keep in mind this build is going to be used with the htc vive

  1. It is, but this is cheaper and has better caps. I'd pick this instead to be honest.

    EDIT: didn't see that it was SFX sorry yeah that will be fine.

    EDIT2: But the case takes ATX power supplies according to the info page? Sorry for the post spazzing
  2. the psu is fine and the wattage is enough.
    the fan might be a little bit loud tho and its unknown for how long it will last (the fan is an unknown brand).

    the build is great

    I think it does actually, according to the newegg description

  5. if you google the case and look at the specifactions , it exceeds the limits :)

    anyways op if you read this and you can swap the unit around, defenetly do it for a cooler master v series 550w, or evga supernova gs 550w.
  6. Yea I just received the unit last week so it shouldn't be an issue to return it. It was my first time purchasing from B&H so I hope their return process is painless.

    bh has a greta service , and you got 30 days try-out time there :)
  8. Yea I'll give this one a go if you think it will be sufficient and BH will let me exchange.
    Side note: there will be two additional storage drives "500g ssd & 2tb hdd" that were not included in the parts list.
    Soooo maybe that extra 50w could help.
  9. never use caclulators , a normal hard drive uses 10w under load an ssd even less.

    anyways use this chart: http://www.realhardtechx.com/index_archivos/Page362.htm
    to see if your psu can deliver enough juice.

    but if there is 500w on your psu doesnt mean its good quality, or it can actually deliver that voltage.
    its about the build quality and voltage stability, if you got nothing to do read this:
    http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html

    tier 1 and 2 psu exceeds their wattage stickers safely.

    again: psu evga supernova gs 550w cooler master v 550w would be greta for you.

    if you can find a utility that monitors wattage draw during useage it will tell you what you're your using and what you need

    generally, you want the usage to run generally 50-55% of the PSU max power, with brief jumps to 75% - this was what an electrical engineer explained to me when i was selecting a PSU. If you go to the specs on whatever PSU you're looking at, you can compare what happens to the current as the wattage draw goes up, in terms of inefficiency as well as distortion(s) in the current.

    I'm using a Cyper Power UPS and it came with a watt meter widget that stays at the bottom of my screen. I'm running that same vid card (GTX 1070, TDP of 150 watts) and between it and my CPU (84 watt max TDP), i rarely see wattage go over 178 watts when running 4k videos. When i'm rendering a video, it jumps to 220-225 watts as the CPU is being run at 98-100% load but the graphics card is idling - on my 450 watt PSU, i'm in my comfort zone. And those numbers include the power the display monitor is drawing, as it's plugged into the Cyber Power UPS, and not taking it's current from the PSU.

    But point is, your usage will determine what you're drawing - don't just add the TDPs of the various components.
  11. So , im in the exact situation : will my gtx 1070 , i7 6700k , 3 fans , 1 monitor 1 hdd + 1 ssd and mobo need more than 520w ? Im talking about seasonic 520w moddels . I can either pick up the fully modular version of the 520w , or a non modular version with 620w , at around the same money . I would preffer a modular psu , as the case is the define s , so no psu shroud , no bigg room to stash all the cables
  12. So I decided to go with the evga supernova 650w gs "http://www.evga.com/products/product.aspx?pn=220-GS-0650-V1" because I upped the build to a i7 6700k, and evga gtx 1080 sc blower style "better for micro itx" and it fit my needs perfectly. Thanks for the recommendations fellas.
