How many Watts of Power Supply i will need?

[nikos123211]

Hello, im a newbie on hardware etc. Im gonna build a new pc but i stuck at Power Supply. How many watts i will need? Here is my specs:

Intel Core i7 7700K (4 cores 8 threads)

x1 Crosair DDR4 8GB

x1 Standard Sound Card

Arctic Liquid Freezer 120 (WaterCooler)

320GB HDD (used and old af)

x1 LG CD-RW

x1 Floppy Disk (semi-broken) (and old af)

x1 120 mm Fan

x1 Asus GT-740 (still used and old af)

and Asus Z170 Pro Gaming.

(I know, the funniest build you've ever see)

Not much.
Which "standard sound card" did you put in your build?

As it stands that build will not need more than 250W of a PSU
Since there are rarely PSUs below 450W that come with decent quality I suggest going with a 450W or 550W PSU (depending on if you're planning to upgrade you GPU to something much more powerful)

 

[James Mason]

A 550w will cover any GPU upgrade you get, unless you don't need one, but I'm not sure why you need 7700k and a floppy disk drive.
You should get an SSD with a modern system to benefit from what the largest noticeable "speed" increase you get from that hardware as well.

I know dude, you're right but i spend all of my money, i can't buy anything now.

Im using a Creative CAO 106-DAT

 

[nikos123211]

Well , sorry but you guys was somehow wrong, i buy a 550 Watts
And it didn't worked properly, i send my computers at Service and they told me that i was needed more watts, now i paid extra 80€.

 

[Isokolon]

yeah....that's bullocks.

a 7700k overclocked needs no more than 150W
8GB DDR4 --> 15W
Asus GT-740 --> 65W
adding 150W for all your drives (which is way more than they'll actually use, but they're old)
you'll be below 400W at maximum performance.

in real life scenarios and at stock speeds this build doesn't need anything near 550W
in fact there are people running an i7 with a GTX1080 and an overclock at 550W

a 550W PSU is easily enough unless it's some junk unit that can't deliver what it claims.

Then whats the problem with my pc, i buy all the parts of my new build, i connected everything, windows 10 boots up sayng (geting your devices ready) windows boot up successful, i try to launch a game and my pc (crashes) with a random color ( no bsod or anything else) i reboot and everytime i launch a game that thing happend over and over, i boot into BIOS and i set my hardware performance (i think was named like that) on Power Saving mode, i did that on Power saving setting on windows, i launch games with no problem but later that happend, an unexpected bsod, then everytime i restart, after bios on windows loading bsod (each time with diferend error code) like happens again and again for about 5-6 times after multiple reboots, after all those bsod windows boot up successful again, i restarted and then i run benchmarks, no issues there, i restarted to make sure that everything works fine, after restart i launch a game and i played for about 2-3 hours and there bsod again, (im 100% sure is not the temperature) and then i reboot multiple times and everytime bsod appears with different error code.

 

[Isokolon]

honestly, sounds like a bad PSU or some faulty part messing up the board regulation

@nikos123211, watch your language.

Well, if you was on my side what you was going to do, buying an 690€ build and it results on to a useless build? The answare is not (nothing)

If the PSu was the problem, it wouldn't BSOD, the computer would just turn off.
It's more likely a faulty video card, or other piece of old hardware. BSODs also tell you what the specific error is when it crashes, and you can look those up to find out what the real problem is.
Though maybe if you bought the cheapest 550w PSU you could find, it may not actually provide 550w, but that would still result in total powerloss and not BSODs. Were you using the same windows installation that was on the HDD from the old computer and trying to run it on the new one? that also won't work and will cause crashes like you experienced.

Honestly, I see a pattern here of sloppiness and cutting corners. It looks like you just slapped a bunch of random parts together with little research and skipped some steps. You've cost yourself a lot of time and money as a result. Start by reinstalling Windows 10 - while it's better at moving to a new PC than older Windows, once there were performance issues, there was no excuse to avoid it.

I try to reinstall but it finished unsuccessfully.

So either something is wrong with your HDD, or something is wrong with your windows 10 install media.
