content: Hello I am Konrad (TwoOfFive)I am a Thirteen year old engineering and computer enthusiast. I love the EEVBlog videos, so I decided to join the forum.I am not that experienced in electronics, and most of what I know is from the EEVBlog and my dad, but I still have a largeinterest in technology and I have designed and built a few projects.A few things I have going on (as in if I'm bored one day I work on them)A sonic networking device, although this is only in the conceptual stages.A handheld games console based off the raspberry Pi. (75% sourced and designed I have made the most progress on this one)A network streaming service for videos and such (My dad asked for it)A network controlled thermostat based off the raspberry Pi (My dad asked for this one too)And lastly I am gathering every episode and movie of Star Trek and putting it on a 2TB Hard Drive.I also love video games (Skyrim, Half Life series, Anything from valve really.)Hi!

content: Welcome to EEVBlog.Projects are a great way to learn and you get the satisfaction of what you made being useful too.Valve have made some of the best games I have played, they had me at the Doom reboot, spooky games hit the world with that title.Never played Skyrim, my son has... but I have still to play BioShock so that qualifies me as a luddite.Star Trek... nothing with ever beat ole Tiberius himself!Must admit to liking the JJ Abrahms films, but all that politically-correct faf of TNG was not for me.Play the music and do the judo dance.. da da dahh dahh dahh da da dahh

PCMasterRace, etc. I actually work for Cooler Master, I'm the guy who tests and analyzes their PSUs to make sure they're safe, reliable, and perform well vs. the competition (which is why we've discontinued a lot of old units in the last two years and our new units are winning awards again). If you can give me the brand and model # of your PSU I can let you know its quality/performance and if you should be saving up for a new one or not. The PSU is the heart of your PC.

content: Which one? Antec's made a few 1200s. Most all of them are pretty decent. I ran an Antec High Current Pro 1200W for a while (it was a PVT sample I got after CES from a friend who worked in their marketing department).Don't worry, this isn't a company account, I'm not going to shit on our competitors without fair reason, nor put lipstick on a pig re: our own products. Though if it's a CoolerMaster PSU vs. a roughly equivalent competitor's unit, don't fault me for picking a side.

content: Ah, the red racing stripes is the True Power Quattro, or TPC-1200. They're pretty decent units, made by Enhance. Solid design, Japanese capacitors, reasonable performance. Efficiency is a bit lacking by modern standards and the fan is a bit noisy, but electrically you have nothing to worry about.I will say, I did see one weird failure from a TPC-1200. While I was at EVGA we had a unit called the SR-2 1200W, which was literally just an Antec TPC-1200 with a few extra cables and the EVGA logo on the side. For whatever reason we sourced the unit from Antec, who sourced the unit from Enhance. Don't know why we didn't buy direct from the OEM, kind of dumb. Anyway, we had one of these units on the test bench with a load of 1A @3.3V with all other rails open circuit. Suddenly it went *BANG* and huge streamers of confetti shot out the back, and the whole lab smelled like death. When we opened it up the two bulk storage caps had both exploded.Turns out that the optocoupler for the main feedback loop had randomly failed, which caused primary voltage to go >500V and blow up the 400V rated caps. It was a random failure, so not something you should worry about really, but it is an interesting story I like to tell. :p

I haven't seen such a thing on any quality PC PSU...Really, just this switch alone makes me think that this PSU is an overpriced chinese cracker. I might be wrong, but that switch there is really jarring...

content: Quote from: TwoOfFive on February 05, 2015, 01:18:52 amI'm sorry to have to say it, but it kind of isn't. It's a decade-old design from YoungYear, a not-particularly respected OEM. It's also been overrated. It may claim four +12V rails (probably false) of 16+16+14+14 amps, but if you do the math you'll find that comes out to 720W, more than the wattage on the label. And there's no combined wattage listed for these rails (as there should be, considering they share a transformer tap, inductor, and rectifier). Based on what I can see of the layout and heatsinks I'm going to guess that the actual +12V output is in the range of 40A, and actual useful power output in the range of 500-600W. Assuming that ripple stays in spec, which it probably won't. You can also expect efficiency in the 70-80% range at best.I really hate to see young players fall for these overrated power supplies. It's a reprehensible scam, but the only people exposing it are reviewers, and there aren't very many of them. And the ones that are out there focus on reviewing high-end units these days, which nets them more page views/ad revenue.

content: I picked it out right from newegg. And it works perfectly fine. I ran 8 drives 120 Watt processor, and a high end graphics card. It didn't even flinch.And maybe it is 720 watts, and they labled it to be conservative.No clue, but no ads, no propaganda, I even have use another one of these to build my grandfather's machine. It was cheap and decent, so I gave it a try. It's still ticking to this day. Even still I am sticking with it, there was nothing really else for that wattage. Everything is either 1000 watt or 500.

content: Unfortunately that's the type of post hoc reasoning that allows these scam artists to stay in business. I spent three years as a PSU reviewer and consumer advocate before entering the PSU industry in 2012. Predatory companies like Apevia, and the shit products that they sell, are just the sort of thing I got into this business to fight against. I can assure you, your PSU is not conservatively rated. And it works fine for now because that's what these PSUs are designed to do: work for now. They typically die explosively shortly after leaving warranty, or just slowly develop erratic behavior and fizzle out. And in the meantime the out-of-spec ripple and piss-poor surge protection are causing cumulative damage to your PC components. It's the computer part equivalent of the white van speaker scam, only a bare couple notches above non-functional, so they can get it on Newegg.This isn't just me talking. Ask around on EEVBlog, or onJonnyGURUorOverclock.netHere's a review of another Apevia power supply:http://www.hardwaresecrets.com/article/Apevia-Turbolink-ATX-TL450W-BK-Power-Supply-Review/1212/9I have half a mind to buy one of these to run through our load test, and post the results on the forums. It's a conflict of interest though, since we're technically competitors.

content: Quote from: TwoOfFive on February 05, 2015, 02:25:53 amThink about it. If your cracker blows up and takes other components such as CPU, GPU, mobo, HDD with it into the grave, what will you do? If that happens, you will have to buy more than just a PSU to get a working PC again. Do you want to risk that?Just a random pick (by no means a strong recommendation): A SeaSonic S12II 620 PSU goes for USD 65 at Newegg.What would the cost be if you just replace the PSU now?What would the cost be if you would need to replace a blown PSUanda fried hard disk? (let's cross fingers that the GTX970 remains unaffected)Compare the numbers...Also, look around in the interwebs. You won't find any reviews about your PSU. Nada, zilch. How can you have any kind of confidence in this thing?And just for keeping the spirits highHere is a review aboutApevia's Warlock series. While it is not the same series as your PSU, it shines a not-so-pretty light on Apevia. From page 2:QuoteSeriously, get yourself a decent PSU. 60..70 dollars should not break the bank. After all, you have proven to have enough financial prowess by buying a GTX 970, ehh

content: I can't. No money. No means to get any. Not enough for anything better then what I got. I can't replace it, and I can't do anything about it.I am sticking with it even still. I have trust in this power supply, and I have used it before with great results. I am so aware I could get a 'told you so' and 'in your face' about this, but I can't change it even still. Trust me if I could have bought a 1000 watt EVGA supply with modular connectors, and a diamond encrusted platinum aircraft carrier, I would, but I had 100 bucks at the time, and I needed a new PSU and a new case.

content: Quote from: TwoOfFive on February 05, 2015, 03:47:21 amWell, in that case i seriously suggest to remove the GTX970 from your PC. This should be the most expensive component (about 3x the value of the CPU or mobo, i guess). Keep regular backups on an external HDD (which you would do anyway, i guess).This should (A) limit the possible (financial) damage in the worst case scenario while allowing you to work with that machine, and (B) reduce the load for the PSU and therefore keep the system safer. Yepp, sorry, no games except Minesweeper and Spider Solitaire.Nobody is asking you to shell out 100 bucks. Decent models you can get for about USD 60...70 (Even with overclocking in mind, a decent 600W PSU should do.). It should be possible to save that kind of money for a proper PSU in a reasonable time frame.If you eventually saved enough money to get a decent PSU, the GTX970 can be put back into the system.In a PC there is only one component that has the potential to kill most, if not all other components in the system. It's the PSU.If a CPU fails, only the CPU fails. If a HDD fails, only the HDD fails. If the GPU fails, only the GPU fails.But if the PSU fails, other thing can fail as well.Anyway, in the end it is your decision...

content: I will keep note of strange events and act accordingly. Removal of the 970 isn't possible. It's the most expensive, but most important part of the whole rig and several things depend on it. the 8000 graphics aren't enough, and don't have the ability to work. As I said I have faith and trust in the PSU. I know it works fine despide Apevia being a bad company. I have had these before in other rigs and they worked perfectly fine.Thanks for your suggestions, but they are impossible for me to do. Replacing or removing is out of the question. It's like removing the alternator and steering wheel from your day to day car. It just can't be done.I have done tests on it, and everything checked out fine. The caps are good, and everything is proper. And if it does fail, I'll sent it in for a Mailbag, so maybe Dave (I hope that's his name) can check it out.Also if this does fail I TECHNICALLY have a replacement PSU. The reason I say technically is because it's lower wattage, only has 4 molex and 4 sata (no video connectors) and only 2 rails. Barely enough to do anything with.Meanwhile, hello!
