Furmark and prime, same time, burning smell.

Re: Furmark and prime, same time, burning smell.

At 240V, those diodes are good enough for a power supply that blows up at 300W.

I see that the it is "sacket" 775 ready.

Re: Furmark and prime, same time, burning smell.

Sun Pro has worse, that's for sure. Tiny diodes though...

Re: Furmark and prime, same time, burning smell.

Please use dremel or wire cutting pliers to ged rid of those disastrous fan-strangling grills , the one behind the exhaust case fan at the least.

Re: Furmark and prime, same time, burning smell.

Are you sure they are SunPro? Just to be sure.

Yes. Definitely Sun Pro. TB-______ markings on the 2nd line of the transformer are a giveaway.

Re: Furmark and prime, same time, burning smell.

Quite good PSU, but I would recap it for long-run.

Re: Furmark and prime, same time, burning smell.

The only other I had lying around that I had to put in my pc is a fsp group 300w FSP300-60THA

Re: Furmark and prime, same time, burning smell.

Here these PSUs with almost the same label have been made as Eurocase (Partis is the company selling it here). I have one similar and to be honest, it is really much beefier, also has 14cm fan. I have also beefed the capacitance everywhere by great margin. Using it as spare/testing PSU, over years it handled up to aproximatelly 400 W load.

The thing is, this Partis company seems to be recycling it's PSU series every several years. So as long as this model has been tough to get in last 2 years, it is poping again on market. Want to get them on ym bench too

Re: Furmark and prime, same time, burning smell.

It's a Sun Pro. No wonder it died. I REALLY would have replaced it before it failed, as it could have killed your PC. I've killed several Sun Pros on my load tester before. They usually go kaboom at around 300W.

Re: Furmark and prime, same time, burning smell.

I am so sorry, started this thread when drunk and completely forgot about it.

Anyway, I was playing dead island yesterday and got the same smell.

My pc went pop and turned off, the psu gave up on me. , took some pics for you to look at. Sorry they are 2/3 months late.

The psu looks crap inside, I now have a 300w psu in my pc and its fine, no funny smells when playing dead island.

Also included pic of inside pc, The front intake is on a switch, i only use it when playing a game.

Please dont shoot me.

I must add that I had also just put a little OC on it, only to 3.2ghz.

Re: Furmark and prime, same time, burning smell.

You are talking about 73 watts top here plus you have intake fan and the rest goes through some grills I guess thanks to natural convection.

Can you see the difference between this and 89, maybe even 125W Athlon 64 X2 6000+ together with 165W HD 3870? That is 300W worst-case scenario. With just crappy PSU with low efficiency pulling all that heat through itself, also remember the hotter it runs, the worse the efficiency is. I sometimes wonder how the crap PSU's can sustain that for all those years. But when everything inside has 50-60 °C, people are just shortnening their components lifespan. Remember RoHS and stuff.

Before making any more recomemndations, I want to see his internals. May have stock HD 3870 blowing air from case, just dirty and with degraded thermal compound. And no intake fan. May as well have some custom design like Sapphire's, keeping all the heat inside the case.

Re: Furmark and prime, same time, burning smell.

My PC has a single 140mm intake fan, 2 92mm CPU fans (push pull). The only exhaust fan is the bottom mounted PSU fan, and it never hits much more than 50*C under load

Most of the PCs (Core i3) I build have the stock intel cooler and a single 92mm exhaust fan. They idle at around 30*C, and hit maybe 40 under load.

Re: Furmark and prime, same time, burning smell.

The number of fans is not relevant, the airflow is and the components you use is.

Erh. I always thought the more fans, the more airflow

[mariushm]

Re: Furmark and prime, same time, burning smell.

120mm fan o psu (off when idle)

120mm fan o cpu (low speed when idle, about 1000rpm)

120mm fan in front of the 4 hdds (antec tricool, lowest setting)

140mm fan on top case (lowest speed, about 7-800 rpm when idle, sometimes up it to medium (1200rpm) or high (2400 rpm) when doing video encodings.

passively cooled video card

no problems for the q6600 and no problems to sleep at night. The number of fans is not relevant, the airflow is and the components you use is.

My system is on the more expensive side though, with the Seasonic X-650 gold efficiency doing up to 92%, the video card with Accelero S1 Rev 2 doing a hell of a job spreading the heat .. etc

Re: Furmark and prime, same time, burning smell.

That is not true. I just got 9800 GT + Q8400 system under my table for testing. PSU is pushing air arround 50 °C, both VGA and CPU have over 70 °C and there is CNPS7000 in full copper on that processor. This configuration is better low-end by todays standards.

There is 120mm outtake, but I am afraid on 5 V it has too low airflow. Also the like a "grill" in the case I would rather cut off, there is more steel than holes in that.

I guess with all those tiny high-RPM fans you never met a thing called silence, right? And who the hell with at least a bit of sense uses bloody Prescott Xeons these days? So sorry man, but you what you have is insanity, I would not advise anybody about cooling being you

I have twice the compute power as you in the same power envelope (Phenom II B50@3,5 GHz) and probably lower noise. The most noisy things in my computer are the three 15k Enterprise SCSi drives.

Re: Furmark and prime, same time, burning smell.

If you have enough of them, you can subtitute 120mm fan, but still, bigger one does the same work quieter. But pulling as much as 250 W through PSU only or PSU+92mm only is stupidity, sorry to say, but that's just it.

ok, by those standards (counting PSU fans) I lied.
There also is a 92mm case fan and each cpu cooler (it's twin xeons, 3.2ghz Gallatin) has a 60mm fan on it. Why? because that's what my case allows for. there is a thread with pics.

The PSU it used to have had two 80mm fans... that's now in my HTPC, which has a spot for an 80mm intake which until I get an 80mm PWM fan, is unpopulated. It has a copper cored stock 775 cooler (Pentium dual core, 1.8ghz). I may not populate the fan slot since it never got very hot anyway.

Furthermore, unless we are talking an OC'd gaming rig or a really hot system (pentium D's and their Xeon sibings come to mind), you don't need much in the way of case fans. Often times, an 80mm plus a decent cooler (like the stock one) will do just fine.

None of this applies to USFF boxes or imac G5's, since they are so cramped that air can't flow, period.

Re: Furmark and prime, same time, burning smell.

None of my current computers use any 120mm fans... 92mm at the largest. Please don't shoot me!

Re: Furmark and prime, same time, burning smell.

You have bad cooler and bad airflow. Basically, people should be shot for not using at least one 120mm output fan. I have 8 fans in my computer together.

As for the supply, I would say it's one of those Partis sells here as EuroCase. They are, well, hwo to say it…each generation is difference. Have 550W version and with all the capacitor upgrades, I think it can do 450 W combined. I have tortured it with Athlon 4800+ (Toledo!!) and HD 3870 and it survived. Tortured it with Brisbane and X1950 and it survived. It's one of the better ones, but still, not so great, not much protections, not fantastic efficiency.

If you pull all your power through that PSU eithout any other fan, here is it: you deserve it to burn down. Is that enough for you to do something with that?

Show us pictures of your whole case insides and prep some money for cooling.
