Question I need a replacement PSU for my Cyberpower PC.

Hello,

I made a purchase a few years ago for a cyberpowerPC and have always had issues getting the pc to turn on consistently. When it first arrived, I thought it may have been defective but whenever it "felt like" working, it would boot up. Once it did, I would avoid shutting it off and just put the pc to sleep to avoid these boot up issues. However, after replacing a few outlets in my apt that required the circuit breaker be flipped off, it hasn't booted up and it's simply driving me mad.

I've read online in regards to CP's standard power supply as the culprit to any start up issues and I believe it may be the same case for me.

I could really use the educated opinion on a replacement for my rig as I am not all that knowledgeable on custom ordered PC's.

Below I've provided the parts to my PC if that would help offer some insight. Thanks again for taking a min to read if you can help:

Hi Karadjgne, thanks for the reply and list of options.

However, I am concerned about the other issues you mentioned that could be contributing to my pc's power stability and life span. are there any tips you advised I make a habit of should other parts of my pc's build be failing or symptoms to look out for?

Things seldom break anywhere else other than the weakest link. If you consider a motherboard, no matter how well made, how nice a quality, how expensive, there always the possibility of just one small error in solder joint, a substandard capacitor or diode that was part of a shipment numbering in the millions etc. Its impossible to get around and honestly more stress than you need. My Grandfather told me countless times 'If it isn't broke, it doesn't need fixing' and that applies to pc's very much so.

As long as it runs fine. its fine. The only maintenance required is occasional dusting, and occasional anti-virus/malware checks and occasional cleaning out of the junk/temporary files. That'll keep the temps regular, the pc safe and healthy. Other than that, just enjoy it, it isn't broke. It will let you know when it is via frame drops, high temps, instability etc.

The psu is the heart of the PC. Literally. Its directly responsible for every single volt and amp in every single component. A good psu with good outputs and built to handle whatever stress you apply is not essential, I'm sure you could live a normal life with a bad heart with proper precautions, you'll just not live a full and spectacular life. And neither will your pc. So starting out with a great psu, you can take that off the table as far as considerations for stability issues.

As far as watching for stuff, there's really only one thing you should watch with any regularity, Temps. If idle temps climb, time to clean the pc, especially the cooler. if load temps climb, but idle is good, in the same game, maybe time for repaste, check fan curves, clean fans/filters etc. You'll know, the pc will tell you.

But otherwise, just have fun..:D

The one in the link is the FM, not the FX, which has been discontinued as it was, and fixed as of January 2018. The problem was with Vega cards which have excessive spikes, well over the psus limit and last longer than 10ms, tripping OCP in a heartbeat. When you take a 210w card, a 550w psu should normally be more than plenty, but spikes upto 600w, for over 10ms is way too much.

Shorter duration spikes, no worries. Look at it one way and the OCP is doing exactly as it's supposed to do, protect the components. From the user point of view it sucked, their stuff constantly crashing. Can't blame Seasonic, blame Amd for making a card that'll spike that high.

But Seasonic took the hit, and fixed it. So no issues unless you have an original FX, pre 01/18 and buy a Vega.

I'm aware of that issue, yes. Are there others?

No, what issues should I be aware of?

that's indeed the old issue. the second one is a rather unlikely, but very heavy one. when overloaded to 120%, the PX 750 would show a staggering 268mV of ripple, which is over double what atx specifications would allow, and over 5 times what I'd prefer.

edit: this counts for models AFTER the 2018 fix

this has been solved with the 2019 versions of focus, being gx, gm, px and sgx.

and the shutdown on ocp was actually across the lineup tested, and indeed partly fault to the gpu makers.

Oh. Yeah. That. To me that's not an issue. As such. If you are dumb enough to overload a psu to 120%, you get what you ask for. If that was at 100% rated output, that'd be different, spikes aside, but a 120% load is 20% more.

My tires are H rated. That means stable upto 130mph. If I drive 20% over that, it's 156mph. If the tires blow, that's on me for being stupid. A 750w psu shouldn't be expected to put out 900w and stay within ATX standards on a load.

If you are pushing a 900w load, (that's 120% of 750w) you should be using a 1000w psu or better in the first place.

and i think that a psu should be able to at least meet atx spec until shutting down. focus clearly can't handle this, and even if it's an unlikely issue, it's a very major one in my eyes.

hence i only recommend 2019 models of the focus line, with other options from cwt's lines and such

you know i agree it should be able to handle overload since it has become some sort of industry standard for psu to handle overload while providing within spec performance until its protection kick in

the problem is no person ever reproduced the results of pceva and you have seen other reviewers that tested 120% + overload with that model and didnt get out of spec ripples

your method of judgment on the psu is only flawed in one area , you base your opinions on the results obtained by any reviewer , regardless of information on his lab equipment , calibration of his equipment , and competence & reputation of the reviewer

You can be the best Cardiologist in the world , and following the clinical practice guidelines of the American college of cardiology , but without having proper calibrated equipment all your hemodynamic parameters ( Blood pressure , Heart rate , ...etc) and blood analysis ( cardiac enzymes , electrolytes , ...etc) would be inaccurate and cause you to misdiagnose your patient
