There's no way this is right.. Right?

[Wolther]

I'm looking at getting a 500 watt Psu and wanted to see if it was enough.. Is this wattage calculator actually accurate? I'm going to get the 500 watt Psu regardless, unless if I find out it requires more but.. ?

[Infernal Burrito]

There's nothing off about it, at least as far as I can see. Those are power efficient components.

[mbryant]

Doesn't seem quite right, but I don't know how much the 370's draw. A 500W PSU is fine for that build 

 

By "quite right" I mean I feel it should be slightly higher, but as a ballpark figure I'd say that estimate is close enough

Okay thanks, was just worried  have a good day/night.

Stay away from any form of PSU calculators they're inaccurate. Best way to find out how much power consumption your system will draw is by looking at CPU/GPU detailed reviews.

[ivan134]

PSU calculators are useless. Read reviews of the products you want to buy to find out what they actually consume under normal use.

PSU calculators are good enough for a vague measurement, and looking up detailed reviews is time consuming and often pointless for most people. Most people get a bigger PSU than they need anyway and if someone wanted an exact calculation of power consumption, they couldn't get it anywhere anyway until they build their rig and measure it for themselves due to variations in components used and method of measurement.

1 - stay away from PSU calculators - they are random bullshit generators
2 - that build only needs 220W under load but getting a decent 500W will allow for future upgrades. I'd suggest SeaSonic S12II, XFX TS, EVGA G2/GS/GQ, Antec HCG

I'm sorry what? Are you saying a 200W PSU will be enough for that build? lol

That entire system will never breach 200W under load, if even 150W. As people have said here, power requirement calculators are trash.

No. Plugging in all the parts you're buying into a PSU calculator is more time consuming and less informative than going to a review and going straight to the power consumptuon section to look at charts and reading the littke write up.

Eh, it's less time consuming, took me like 3 minutes to plug it in using my phone. But I also agree, it is less informative but did give me a ball-park estimate. Next time I will be reading reviews/charts as that only took me 10-ish minutes to do.

You sure? the CPU and GPU will be about 200-230 ish under full load + the other components too would add some wattage. I know the calculator will not be 100% accurate, just wanted to give it a try and it seems like it gave a ballpark estimate. Thanks for the info, I will stick to looking at graphs/charts in the future.

A system with i3 6100 maximum load: 75 W

Maximum r7 370 load: 130 W

~200 W for maximum load

If by some strange reason OP needed to, he'd power it with this: http://pcpartpicker.com/part/silverstone-power-supply-st30sf

 

I like how most 500 Watt PSUs (around same efficiency) cost less than that 300 Watt one ._.

You're saying it takes 3 minutes to google R7 370 review and find the power consumption section? Okay guy.

Yes, I know what you said and you said that takes less time.

It did for me, for the reviews I wanted to know if the information I was reading was correct, so I compared it to another source. For both CPU and GPU, + I read other information about overclocking the GPU aswell. Yes, reading reviews was more time consuming, but it is well worth it judging by how much info you get from it.

A PSU calculator is not another source, other reviews are. Even if you hate reading, most of the popular reviews have easy to read charts. All a PSU calculator does it take worst case, unrealistic scenarios (like futuremark and aida 64) and spits out irrelevant and misleading numbers.

1. I probably should've been clearer on what "other source" I was referring to, I did mean another review.

2. I wanted the worst case scenario so that I know no matter what I do I do not go over the wattage usage, this is why I set my calculator to 100% TDP. 

I'm probably not as smart when it comes to power usage, and idk if that was the correct approach to go over the max wattage my system could output. 

I'm not disagreeing with you that it will not give exact numbers like I have said many times before I will be using reviews for my future research once I get another PSU down the line.

No matter what you do, you will never reach the worst case scenario because there are no consumer software that do that. No game, rendering software, etc will ever get you close to that worse case scenario because those worst case scenarios are only caused by stress tests. You can run an Fx 8350 and a 290x on a 550W PSU. Put an 8350 and a 290x in a PSU calculator and let me know what it tells you.

The wattage is about the same as 500W, it might've overestimated a little bit, not sure cause I don't know anything about those parts. And okay, thanks, good to know most programs won't give me the worst cause scenario

Wow, I'm actually impressed. This is the 1st PSU calculator I've seen that actually gives realistic numbers.

Well the i3 uses about 50W under load and the GPU shouldn't even breach 120W seeing as it's a 370 so yeah, 150W-200 is a good ballpark estimate. People wildly overestimate how much power PC components use. Here's a GTX 680 and i7 3770k, both overclocked to the wall, and the total hitting 350W.

 

 

 

His explanation of 80 PLUS efficiency is wrong but his system readout is correct.

 

And hard drives and SSDs use negligible power and aren't being stressed heavily enough to make literally any difference when the CPU and GPU are going to town.

Yep, seems 100% correct. People always overestimate their power needs.

(says the guy with a single 390 and a 760W PSU... it was on sale, ok? )
