I am a day trader and looking to buy a new PC. I use 6 screens for one brain PC. I have at least 20 windows open on google chrome at a single time AND a trading platform opened. I also run my business which is a trading website from this same PC. I know NOTHING about computers and was wondering if you can tell me what I need and would be best. I need it to run fast with many things open and able to save many things as I make a lot of videos and save charts and word documents to share with my subscribers. Your help would be GREATLY appreciated. What are the specs I should look for?

I thought that computers burning down was just a joke. A friend told me that he had another friend who burnt his PC. I though nothing of it. I guess I’ll think again…

MetinCrafter says:

Just use 2000 potatos that equals to 1000w about.

Astraldymensions says:

I just bought a 850 Watt and I wasn’t planning on SLI, but now I guess I have the option to. I don’t think my system even pulls 500 watts atm. More like 450 :/

Gucky says:

I wanted to inform about my Watt usage from a new build in 2017.
To get an Picture what kind of PSU you might need.

I use an i7-7700k. On Stock it uses at 100% about 70 Watts.
1x M.2 SSD 512GB for System
1x SATA SSD 500GB for Gaming
1x HDD 7200U/min 4TB for Storage
1x AIO Watercooling
4x 140mm Fans in Total
NO RGB Lighting.

That all is connected to an old 660W Seasonic-X 80+ Gold.
I some test it could get upto 90% efficiancy at 50% load.

While surfing or watching Movies I can see an Watt usage of 100W or
Battlefield on Ultra with 4k Downsampling I can see an MAX Watt use of
While using Realbench form ASUS I had 385W max Powerdraw.
Meaning my PC uses about 350W at max load.

Of cause I can still OC my PC,
in which it pulls about 30-40W more from CPU @5GHz.
The GPU might pull upto 100W more.
So the Powerusage @100% with OC might be about 500W, although i didn’t
test it.

With this or similar Systems I can recommend an 650W/750W Silver/Gold

I wouldnt go with an 500W since its over its peak efficiany when Gaming
and there is no headroom for OC.
But that doesn’t mean you can’t use an 500W PSU, just don’t overclock
that hard XD

If you want 2 Graphiccard’s I recommend at least 250-300W more Power.
Since the GTX 1080 Ti’s use ~200W or up to ~300W with OC. In this Case
go for an 850W or 1000W.

When my PC is off it draws less then 1 Watt XD.
Measured with an ELV Energy Master Basic 2.

About Efficiancy:
Good Gold PSU’s can hit over 90% efficiancy at 50% Load, meaning with my
system at 100% load the PSU “wastes” only about 30-35W.
While bad Bronze PSUs can waste over 100W in this Case.
And Titanium (the best and most expensive ones) would waste only 5% or
about 15-20W @50% load.
Yes only 15W less for 100$-150$ more cost for the PSU. That may only be
10$ per year savings.
But Titanium PSU’s are more durable have “cleaner” (stable) power and
have a longer warrenty. ^^

I recommend a good 80+ Silver or Gold PSU for 100-150$. From Seasonic for example.

Jakeulous says:

Kaliss says:

PSU calculator recommends I use a 650W PSU but I have a 750W PSU that auto shuts off when I try to run a small Ark server and Ark the game on medium settings. Not sure if the calculator is accurate.

I use a 550W Fractal Design Integra M 80+Bronze Modular power supply. It’s only 550w and it does amazing for gaming.

Tân Phùng Phan says:

One question Linus….How can i check the amount of watts my PSU is making?

the grinch says:

this video is scary

ciaranlikessocks says:

I have a group of friends who game on PC, and one of our newer friends is building a rig that comes to 520w, but the rest of my friends think a 550w PSU will be fine whereas I’m sweating at that thought a bit. Is it ok? The last thing I want is for my friend to be building a a ticking time bomb when I could’ve said something and stopped him.


can i run a gtx 1080 mini with a 410w power supply?

Astraldymensions says:

Ooops… I just bought a 850 Watt and I wasn’t planning on SLI, but now I guess I have the option to. I don’t think my system even pulls 500 watts atm. More like 450 :/

Chris says:

are power supply compatible with all motherboards?

Paul Williams says:

Interesting and helpful video but what about the amps. According to the coolermaster tool my rig needs a 600W psu. I have one. But my graphics card is a gtx 780 and the manufactures talks in terms of amps and wants 42 amps on the 12v rail. Well there are 600w psu that dont make that.

zabriel velazquez says:

ok so i built a ryzen 7 1700 (stock cooler) 16gb(8×2) ram , xfx rx 480 8gb black edition, m.2 ssd 1tb , evga 650w +80 gold psu, asus optical drive, asus b350m-a motherboard, matx case with 1 80mm and 1 120mm fan, while gaming on high -ultra settings everything runs fine, but if i crank it up to 4k ultra settings though performace doesn’t drop at all i get this loud continuous beep from the mobo speaker , until i stop the game or pause and lower the resolution to 1080 where i can carry on for hours with the gameplay, is my issue the 650w psu or could it be overheating?
