psu advice

[Dustin Ray]

my psu have been a acting a little weird lately and i do want to upgrade to a fully modular so the cables reach better. i currently have a cx750 by corsair. but i dont have a bunch of money. any suggestions or links to something fairly cheap in price?

How is your PSU playing up?

What are your specs?

Where are you from?

 

[Dustin Ray]

currently in the usa. my psu is fine for now. i lowered the power limit from the full 750w to 600w and so far no problems but still slowly getting works. specs at the moment is an asrock h310 board, i5 8400 vr, 16gb rgb g.skill tridentz ram, and a gtx 750 ti sc (works surprisingly well with all my gaming but i am looking at getting a rx580 in the near future)

Lowered your power limit from the full 750W to 600W????

What do you mean by this? Your system is like a 250W system. I think your computer just isn't stable.

elaborate on "wierd"

weird like it will be doing fine then all the sudden it just drops in power and my pc dont like that at all. it doesnt completely stop it just goes from like 750 to 200 for a while until i restart my pc

What the fuck does that mean

[Dustin Ray]

the power usage lol.

How are you measuring the power usage?

A 750W PSU will not consume 750W. It means that it is capable of outputting 750W to the system. A system will only pull as much power as it needs. Keep in mind that 750W is DC output to the system. There's also efficiency loss, so the unit can actually draw more from the wall if needed. At 85% efficiency for 750W output it will be pulling almost 900W from the wall.

For your system with a i5 8400 + GTX750Ti you are probably looking at 150-200W under load while gaming and such.

 

If you're measuring the power usage at the wall with a power meter then if it's reading around 200W power draw from the wall that could be about what you should expect from your system under load with efficiency losses taken in to account. You should never be reading 750W power consumption with your system hardware.

 

 

Seems to be a lot of confusion about what is actually happening here. Might help to backtrack a bit, ignore the PSU for now, and just explain what issues you are experiencing with your system?

[Dustin Ray]

yes i know that but the minimum for my pc needs is 312w the consumption shouldn't drop below whats needed

Where are you getting 312W value from?

Please see:

That's MAX consumption while under a heavy load. If you're just sitting on desktop idle or browsing the web your power usage will be significantly lower, like only 70W or something. My i7 6700K + GTX1080Ti with a bunch of HDDs and other shit idles at 90-110W [measured at the wall].

How did you lower the power limit from 750W to 600W?

[EPPHO]

If you think like that then it should consume 312W when it's turned off aswell?

ok so if nobody is going to help why waist your time

You haven't described what your problem is, and replacing the power supply could possibly be a waste of money that won't fix your problem...

From what you describe you have no problem. You have said the equivalent of a customer walking up to a car mechanic and saying "My car needs 300Hp to run, but when I am in 3rd gear at 1200rpm I only get 75Hp, pushing the throttle gets me more power but I need it to be 300Hp at 1200rpm" 

 

In other words you are completely misunderstanding how power consumption works. Your PSU is rated for a max output, your PC will pull what it needs up to that maximum. When your PC is not doing anything it uses less power, and there for you see a drop in wattage, when it is under stress it uses more power. That's as simple as it really gets and describes what you are seeing. 

[Dustin Ray]

omg why is is it so hard for people to get the psu is randomly dropping power below what my pc needs and i constantly have to restart it. the psu should never drop below what the pc needs to run

If someone is being this wrong, and obtuse, the likelihood of them being a troll is quite high.

The way you are describing the problem is a bit.....how shall I say it.....confusing.  Could you walk us through your issue a bit more slowly and with more detail, so that we might better understand the issue.

 

Now Spotty asked a question that piqued my interest as well.  You said the systems power fell below 300 watts.  How exactly did you make that determination?   Do you have your system attached to some sort of power meter?

[Dustin Ray]

to put it simply my psu's power is dropping below the 312w that my pc needs to run and it shouldnt be doing that. idk if its a bad capacitor or coil but i need to replace it before it causes any damage

You need to quote people see they see your response. Nobody you responded to is getting a notification. See the grey boxes with text in them that say "Dustin Ray said:"

 

As for the question that was asked a couple times, how is it that you measure your power draw?

It does not need 312 watts to run. The graphics card struggles to draw the full 75 watts afforded to it by the PCIe bus and the 8400 isn't exactly power hungry, unless you're running a few dozen hard drives I fail to see where you're coming up with that many watts.

now thanks for nothing guys. you cant just help someone out with a simple link link they ask for.

Outervision is known for overestimating by a lot.

 

You need to explain more. How did you

That makes no sense. And what was happening to your system, why do you think your power supply is causing problems? You never described what was even happening but you're getting mad at us for not understanding. From our perspective you never asked your full question.

This is an important one. How did you measure that your power supply drops in its output? What makes you think it's delivering 750 then suddenly delivering 200?
