Is A 550W PSU enough for i7 8700k + 1070 Ti

[Codey2k]

Hey guys! Just a quick little question. I'm building a new PC in a few days and here are the specifications :

 

CPU: i7 8700k

MOBO: Asus Prime Z370 - P

RAM: Corsair Vengeance 8GB

CPU Cooler: Hyper 212 Evo

HDD: Seagate 2TB

GPU: Zotac 1070 Ti Amp Extreme

PSU: Antec Neo Eco 550W 80+ Bronze

CASE: Antec P8

 

Now the question is, is a 550W PSU enough to power the whole system? I don't wanna increase my budget anymore unless if it's absolutely necessary. Thanks for the help.

You will need to increase your budget unless you are willing to sacrifice overclocking (not as important as before with Coffee i7). Both the mobo and cooler sucks for overclocking.

 

Lack of SSD is also disappointing. That a single 8GB stick?

 

Zotac's high end card has bad VRM cooling, I wont take them unless they are really cheap so I have the money to spend on an aftermarket cooler.

 

550w PSU is enough, but this tier 4 unit isnt what I would pick because better units can be purchased for reasonably low prices.

While the system doesn't NEED more than a 550w PSU, I would seriously consider buying a slightly better and higher wattage unit. PSUs are most efficient in the 70-80% load range, plus with a good power supply you can use it for years to come with multiple upgrades.

Seasonic is one of the best, btw.

First of, I recommend possibly getting 16 GB because an the 8700Ks 6 cores might really benefit from some more RAM, also what speed is it?

Second of all, the only time you would ever consider dropping an SSD drive would be if you're going really budget and need to save on money and with a 8700K build, I gurantee you should get an SSD too, here are some good ones:

• Crucial MX500 (500GB): A little expensive at $100 but it's got 500GB which will last you a while
• Samsung 850EVO (250GB): Samsung SSDs are always pretty expensive at about $ 100 but this drive is extremely popular and if you want something very good and trusted than this is it
• ADATA Premier SP550 (120GB): This is a small drive but more than enough for a boot drive. ADATA is also a pretty trusted SSD company and this drive is quite cheap for an SSD. If you're looking to just add an SSD and that's it then get this one.

Also, if you maybe want WiFi than choose the Asus Maximus X Hero (WiFi AC) a very good Coffee Lake motherboard, I have it in my PC in my signature.

 

And lastly, to answer your question, I would check what load wattage you need with a PSU calculator and then (from a trick I learned in a Linus video) multiply the load wattage by 1.15 and multiply the load wattage by 1.25 and that's the range you should probably choose from.

The range I calculated for you was 629.05 - 683.75 so you'll get a 650watt PSU probably.

 

Seasonic FOCUS Plus: $89.99
EVGA Gold PSU: Around $99.99

Corsair RMi650: $129.99

 

Hope this stuff helps

When 1080ti with 8700k systems dont need more than 550w, you know that going higher is pointless (unless you want AMD card).

 

Also, many units are not the most efficient at 70-80%. The older Corsair TX750M for example is most efficient at 30% load.

PSU calculators always go overboard on power consumption, no need to multiply its numbers any higher.

So the thing is, this is my first time ever building a PC so I'm a noob at this stuff. Since this is my first ever PC build, the budget is pretty much non-extendable. Can you guys help me suggest a build for $1800 US including the 1070 Ti and a monitor?

Sure. Question is whether you want to play at 1080P or 1440P, 60 Hz or 144Hz+?

[Codey2k]

Probably 1080P 144Hz since 1440P monitors cost a fortune here.

Tbh i'd rather say that in PMs than here if you don't mind

[Jay Deah]

my 1080ti / 8700k @ 5ghz draws a fair ammount less than 550w and ran fine off a CX550M

 

i upgraded my PSU from a CX550M to an RM650i but only for the quality improvements not the wattage

 

i'm sure you'd be fine
