How much does a i7 4790 with Gtx 970 needs? Cooler master 450w bronze enough?
Europa پیش 3 ساعت
I have a platinum rated 1000w evga power supply, but I have an overclocked 10900k running at 5.0 ghz on all cores with an nzxt kraken aio, and an asus rog strix 3090 oc at 2150mhz at max load. Is my power supply enough? I am going to build this pc in the next coming days and I am assuming I have enough wattage but it would be nice to have some input thanks!

Hmmm. I have a CoolerMaster Silent Pro Gold 1200W that I bought in 2011. I used it almost without ever shutting down the rig for years. It's 80+Gold. Would you trust it in a new build?

Buy a good PSU, a good one will last a long time, a low quality one will not and might even kill your components. My OCZ GameXStream 700W lasted 120,000 hours (14 years always on) before I moved to a new case and PSU.

For anyone in a market where it is avalible I recommend the Fractal design ion+ line (mostly 760 and 860W versions). They are platinum rated at a good price compared to the compitition.

I baught a cooler master 750w bronze and im running a ryzen7 5800x with a rtx 3070 i did a couple of 3d mark runs on them and when i saw in msi after burner it showed on the graph that my power supply hit 1 a couple of times running the test and idk it that was that i reached the peak power usige but i notices it throteling a bit along the test so im unshure if i need a bigger power supply my self (this is my firs build) i also had a bit off problems with cpu temps something i thaught was wierd since im running a corsair icue 150 360mm radiator the temps reached the 83 celcius that is my peak before its throteling down should i mabe rais it i have also chainged the fan rampup speed so that it gets more heat out of the system

Another misconception with PSUs is people think that the Max Rating is the same as the RMS, or average/normal operating wattage. Therefore, if you buy a huge PSU, they immediately assume it’s going to significantly spike your power bill. That’s just not true, unless you’re doing things that cause it to constantly run at or near the max.

Hello, I really like your channel. You give good and understandable information. I am planning on building a system for Photo (RAW) and 4K video-editing. Unfortunately most videos are about Gaming systems. If you have the time and inspiration....could you make a video about a photo/video editing systems and the pros and cons of budget/normal and high-end systems.

I've never cheaped out on PSU's. Current PSU is a Seasonic PX-750 Prime. Running an RTX 2080 and a Ryzen 9 2950X with multiple SSD's and a single hybrid drive on it comfortably. Bought cheap once, I got lots of blue fireworks and the ominous black smoke. I try to run a rule of thumb where I spend 15-18% of my build cost on my PSU.

efficiency has nothing to do with the quality of the component you freaking idiot lol. a 80 white can be better quality in the component than an 80 titanium. haha That score has nothing to do with the quality its the efficiency of the component/powersupply build which has nothing to do with the quality.

Murry's Fallout Silent Cinema
Got a weird issue that just popped up, hoping someone can help me narrow down the possibilities. After noticing my rig was getting kind of hot playing a game, shut down the game and was about to shut down the rig to diagnose the cooling issue (ended up being minor, a fan had stopped working)... the resulting issue wasn't quite as minor, before I could turn the rig off it basically crashed itself off, booted back up just fine, and otherwise seems ok but now it either turns itself off every time it goes to sleep or gets stuck in sleep so I have to do a hard power off and restart. What exactly did I fry, can't imagine it being a software issue since everything was working fine before the crash. Thanks.
Mr Anderson
Mr Anderson پیش 18 روز
Relax, dont think you fried or toasted anything, in fact the pc shut down/crashed in time to prevent that from happening. Might be corrupted windows file/registry or software related problems. Do a clean install of Windows maybe.

Jay... great intro to PSUs... Hope you don't mind, but I have a couple of follow-on questions. 1. PSU Quality... In the past I've had experience of a [well known, supposedly reputable brand] PSU that was offering distinctly "off" voltages [like 10.2 on the 12v rail, 3.8 on the 5v rail]... You didn't really get in to this aspect of PSU quality. The quality ratings you discussed here were primarily efficiency, not delivery accuracy. Wondering if you've ever had issues with system stability from an under-volting PSU? (Can be a real hassle to chase that one down)... 2. Noise... I built a new machine last year (see here, but be nice: www.overclock.net/threads/ocn-water-cooling-club-and-picture-gallery.584302/page-5524#post-28637655) that includes a pair of 2080Tis in SLI, a heavily-overclocked 7920XE and some massive overkill on cooling... By *far* the noisiest thing in my machine is the PSU (Leadex SuperFlower, 2000W). Thinking of swapping that for a pair of lower-rated PSUs... but interested in getting a model where the fans stay idle below a given load (I used to have a Zalman 1250w that was passively cooled up to 40% load). What's your view on the best way to reduce PSU fan noise in already very-quiet machines? Cheers

I have an EVGA G2 but it's nearly 7 years old now. I finally wound up replacing it with a Corsair HXi 850W and my system has been smooth sailing ever since. Also too, efficiency does not always equal quality. I've seen some 80+ Gold units in my years of building systems that are absolute garbage.
kght222 پیش 23 روز
seeing this video i decided to look up my power supply just to see it's rating, i was pretty sure it was 80+ gold. while looking it up i noticed something, i paid like 110 bucks for my psu when i got it, it now sells new for 230 or so bucks. i had to think about it, but i know why now after a few minutes, it has usb monitoring. digital monitoring, and 90% efficient at certain loads.... people are using it for mining clusters. i have a corsair rm650i. i guess people figured out that you don't have to plug it into the motherboard that it powers, or into anything, to use the usb monitoring. so you can hook them all up to one control unit. gives you real time voltage and load monitoring from one source.

if we had a way to monitor how much power the computer is drawing like we have for pretty much every other component in the computer, maybe there would be less confusion over what power supply you need. i tend to try to go a bit bigger just so i know i'll never reach that limit, because i dont actually know what all my components can max draw at the same time
Mr Anderson
Mr Anderson پیش 23 روز
There are actually a few ways to go about it. Hwinfo, hwmonitor etc for individual components. A power meter on the wall socket while you run some benchmarks/stress tests will give you a good idea of what is your maximum usage.
