FSP ATX-500PNR. How bad is it?

post #1 of 7
Thread Starter 
I was told this PSU is capable of only powering office PCs, and has voltage problems that can affect gaming performance and, of course, overclocking. Since personally I did not see any gaming issues myself over 3 years of usage, and a couple basic overclocking attempts did not kill the rig, I have some hopes that things are not too bad.
This same person suggested me to seek confirmation of his words on this subforum.

Ask about your PSU though in the Power Supplies forum, and I guarantee you that at least 1 or 2 others will come along to say that yeah, you shouldn't be trusting it. Its power output is very low in quality. Its power delivery is unstable (high ripple), inaccurate (loose voltage regulation), and has very low-quality internals - which is why it's so bad. There's a reason why it's so cheap. I wouldn't even consider it to be good enough as a 400W PSU due to that low +12V capacity it has. The best use for that PSU is powering a simple office PC, or a paperweight. wink.gif (just making a point hehe)


My rig is listed in the signature. Here are the current voltage details:



Is this PSU capable of any overclocking at all? PSU calculator for my build showed a 406W suggested power, and if that person is right and this uncertified PSU is nowhere near 500W, I can see the problem. But what is this low +12V capacity? Is there a way I can check PSU potential within Windows? Without any chinese power testers and other gizmos. Like a stress test or something...

I recognize that solid\stable OC requires 650W+, and SLI\CF requires even more, and the higher certification, the better. But just like my old Core 2 Duo PC is running on some 300W prehistoric PSU, I thought a budget 2013 PC with single non-hungry GPU would not really need some 600W+ numbers.

Anyway, yes or no, I just wanted to push my aging PC to the limits before considering the change once AMD brings its bombshells to the market. If that's impossible, I guess I can be happy it even works. But I always thought my weak spot was mobo, maybe HDD, but not really PSU.

I just look some photos on internet, looks really cheap inside and even lacks some components of the primary filtering stage. Probably is OK for normal usage but Overclocking with that PSU is like hitting a granade with a hammer redface.gif.
Sorry for being so negative but the M5A97 LE have only 4+1 phases without cooling so keep the overclocking below 4.5Ghz
Look on ebay or craigslist for some used power supply or if you are good with the electronics get a used server PSU and convert it to normal ATX, i have a used some Server PSU on multi-gpu and overclocked setups totally rock solid thumb.gif

Uhm, no, I'm not even remotely that good with electronics. I wouldn't be here asking this question then, would I?

And I can't quite interpret your reply. You seem to agree that overclocking with this PSU is a bad idea, that's a second voice. But then still mention that 4.5ghz is the limit. I was not really aiming for 4.7ghz, the plank of 8320, and even 4.5ghz is not really necessary.

But what about +-4.0ghz stable? I think this is the turbo clock, but I don't exactly know how turbo works. After this thread I intend to hop to CPU subforum to get help there, but I need to know what to go with.

Can I at least have 4.2ghz? 8350 is 4ghz, and from what I know about Bulldozer - it's the same core, from 8300 to 9500+. Just factory clocked. So my PC would fry if I used 8350 stock?

Plus, I have a GPU to consider as well. I've heard that light OC Afterburner style is not really harmful. Can I resort at least to that? Or this PSU is so bad it won't even take GPU OC well?

I'm not trying to protract an argument. I've tried things, I could try things, I came here for a reason - assistance, experienced one. If each and every OC expert has ever worked with some big buck PSUs for safety - then, sure, I am wasting everyone's time, my apologies.

But maybe there are people, who had experience of OCing in not ideal conditions. What could they say about it? Risk, longevity, optimal tests\preparation. Though these questions are probably better asked in CPU thread, I was specifically nailed for my PSU. And until I get a clear picture of it, I can't ask for further assistance.

I have experience on overclocking without proper PSU and components and most of the time i ended up blowing something, that is because i don't recomend you to do it. When i was a kid and don't have to much money to build a gaming PC, overclocking is the first thing you do to get the most of what you have, after triying so many things (Dual PSU, modified crappy PSU) the chepeast way I found to have a proper power delivery is using a old server PSUs converted to ATX

Surely that motherboard can do 4.2Ghz without problems if you have a good airflow in the case especially close the VRM area. Also GPU OC is a good idea you can get a nice FPS boost. But i will never do it without a proper PSU.

My english is far from good sorry

Airflow isn't an issue.

And the item in doubt is not the mobo. I've been told this mobo can do even 4.7ghz, but that's not my goal. The item in doubt is the PSU, and I want to know if it can OC at all, and what could be the safe parameters. I'm not trying to push the limits. I'm trying to polish the performance. Step up to 8350. Try something before Zen is out.
I am not trying to do what a gaming\overclocking mobo and a certified PSU would do. I'm trying to find out what "I" can do.

Again, I'm glad you support the idea of GPU OC. But the question remains - will this PSU do it? At least on stock voltages without bios tweaking?

Or is it really a "paperweight" as quoted in my OP?

Overclocking the whole system for a benchmark session and then left everything stock probably is OK, but still don't recommend to do it . I lie to myself if i say that is totally fine overclocking with your PSU. Sorry redface.gif.

Very well, some things are just not meant to be... I might follow your advice and get another PSU, thanks for that.
