Power supplies

[Avin1913]

Good day sir. Im Avin from malaysia, Im here because im confuse in buying proper power supply needed to build my gaming pc. Can you help me to suggest a good and exact power supply i needed? 

 

My Pc Specification:

Motherboard: ROG Strix Z370-f

Processor: Intel i7 8700k

GPU: ROG Strix 1080ti

Ram: XPG 8gb x 4 ddr4 3000mhz

HDD: 1TB

SSD: 480GB Kingston

NVMe SSD PCIe: 250gb WD Black Series

AIO: ID Cooling RGB 240

Case: Cooler Master H500p

Anything tier 3 or higher, with 600w wattage rating is enough. You can go 650w or 750w if it doesnt cost much extra, but more than that is just wasting money.

So let say in future if i wanted to do SLI do I still need to upgrade or just can go with 750w?

solution is dont do SLI or Crossfire. Effect is poor and both AMD and Nvidia are trying to get multi-GPU into the history books.

Multi-GPU is basically dead. Don't plan on many cards being available to still support it, let alone games. DX12 and multi-GPU is still not really a thing.

Noted that. So i can maintain with 750w right? Because my friend was suggesting to go for 850w thats why I was a bit confuse with that.

For a 1080 Ti? Assuming you'll overclock the system with a water cooling loop, max a 550W PSU. If you don't overclock, 450W.

An 8700k, assuming you get a very good chip that hits 5.3GHz 1.42V (most likely wont), will consume just under 250w of power (more general 5GHz 1.3V will lead to about 180w power draw). Your 1080ti is limited to 330w by the vbios, no matter how hard you overclock (as long as you dont do warranty-breaking stuff). That's 580w total. Storage drive, mobo fans etc might take another 50-70w to run, so that's below 650w.

 

650w - 750w PSUs are already enough. Good PSUs are rated to do their rating 24/7 for years without issue, and many dont even trip over their protection mechanisms until power draw exceeds their ratings by 20%, which means there is a very generous amount of tolerances built into these units.

He's not very likely to run Furmark, Prime95 and Crystaldiskmark at the same time, though.

Ok clear and noted that. A very much thank you jurrunio for spending time to reply my post and I now know which power supply to go with thank you and appriciate it. Tc

"Why are my Cinebench scores so low? I have all the benchmarks running, shouldn't that make my score better?"

An overclocked 8700K and 1080 Ti system doesn't at all demand a 750W unit. The whole system will demand around 450W with all that overclocking.

 

A 550W version of whatever PSU you were looking at is alright. See if you can find a Corsair RMx or RMi. I'm not sure what options you have in Malaysia, but if you can afford the hardware you listed for us, then you should easily be able to afford a Corsair RM unit.

Ya I finally bought it the Cooler Master psu V750 for $105, if convert to malaysia currency will be around 426 bucks.
