    Hey punchers, im having a problem and im a bit worried about it.
    My PSU (A Cooler Master 550W) gives a weird smell after playing games etc on this machine after a couple of hours.
    Does this come because my system uses too much watt?
    My graphics card is recommending a 550w power supply, but i also have a 125watt amd CPU.

    Here a full list of my specs :




    Btw, i already have a fan ducttaped at the air-out place to suck all the hot air out, because this thing gets really warm.

    That's the electrolytes working.

    But really, has this been a recurring problem? Is the PSU new?

    If it is anything burning or nose piercing, you need to get it replaced asap.

    Is the fan in your PSU running properly?

    I have no idea, but not something like roses.
    Maybe something electric or dusty, but theres no dust in it.

    The PSU is as far i know 2 years old, and theres no dust in it, already cleaned it once

    Can it be that my specs are just too much watt to let the PSU handle it?
    And if i gonna buy a new PSU, wich one shall i buy?

    Is the Corsair Enthusiast TX650 V2 a good bang for the buck? its 76 euro's here.
    Btw, i have a top mounted power supply with the fan aimed down

    My dad already cleaned it at his work a month ago, and i cant see any dust in it.
    1 thing to say, before my dad cleaned it it smelled TERRIBLE and the smell stayed in my room, i think its the same smell now, but after he cleaned it it did go away, but now it's back.
    I have my sidepanel removed because of my CPU heatsink, its the only way to not build warmth up in my case.

    Edit: My pc has been on for 6 hours now, only a warm air coming out the PSU now.
    Think of just buying a new case and then we will see.

    The PSU is a Cooler Master 550w, product number is RP-550-PCAA-E2

    550 watts is ample for your whole system.

    The GPU says a 550 watt psu for the whole PC

    There is no graphics card out there that draws anything close to 550 watts.

    If you feel warm air out of the PSU, replace it. You're running too close to it's max if it's actually producing noticable heat.

    A quality unit should run warm but not something you should notice. A cap might be busted.

    6990 can get pretty close.

    Depends on the case. Ambient temp in my case is under gaming (with the temperatures we got now at least) something that could already be decided as hot, and the fact that the PSU outtake air is warmer isn't a problem. Just shows the PSU's does away with it's heat rather well.

    Well, if it is my PSU then wich one shall i buy? Please cheap, or shall i buy a Sharkoon T9 Value case first?

    Theres btw not really that you can feel the warm air when you got your hands at the outtake, but the side of the psu is warm, not as warm that you can burn your hands or something, but just warm, is that normal?

    That isn't really a problem. Especially if your case is small or have bad airflow, the temperature in the PSU can rise.

    How old is the Cooler Master, and what specific model is it? I would probably buy a new PSU, but it isn't necessarily completely needed. It's hard to say when we only really got the smell to go on. Aside from other shit, I haven't actually had a PSU take out actual parts yet, and I've seen some pretty shit PSUs go out with a bang. Still, I'd look into a new one.

    If the side of it is warm, then that's usually ok. My Seasonic S12 600watt was warm to the touch even though it worked very well, even still is working for another FP'er I sent it to after 4-5 years of service for me.

    If the unit is outputting warm air, which it shouldn't need to really do much of, then I would consider replacing it. Especially since your system really isn't too demanding from the specs. The smell is either dust getting in between some contacts, the fan motor, or some sort of chemical leaking from it causing the smell. A PSU shouldn't smell and in any of those cases I'd look to swap it out with something.

    I recommend the Cooler Master Silent Pro series personally.

    Edit: If it's still under warranty, contact Cooler master, I've had good luck with their support, either email or online chat. They can atleast tell you what to check.

    I don't see why a broken PSU would output more hot air than one that's fine. That just means the warmth from the components gets transfered to the air, and that's pretty much the concept of cooling something. A system that's pulling, let's say, 320W at 80% efficiency is going to have 64W worth of heat to get rid of (as far as I understand power supplies and such), and (some of) that heat is going to be transfered to the already hot air that the PSU is taking in. The fact that hot air is blowing out the back of the PSU is not (or not necessarily) a bad sign at all, especially if you have low ambient temps.

    I suppose it seems out of place considering I've never felt a PSU outputting warm air before.

    My CM 1KW, my Seasonic, my enermax liberty, my thermaltake 430, my antec 430, nor any machine I've ever worked on at work. Even the server power supplies are pushing cool or mild air.

    And my room, before I got my AC, unit is sitting around 78-79f, and even under load my PSU's never pumped out any noticably warm air, no matter the fan speed.

    My PSU's got WARM. 650W Antec powering 4870 Q6600 G0 overclocked to piss. AX1200 with my current setup. etc. They all would get warm. I would say around 5-8C hotter than ambient air.

    Hey guys i got the money to buy a PSU, wich one can handle my specs (below)?
    My budget is 90,-

    Found a 700w psu for just 70,- the OCZ ModXStream Pro 700W, is that one good?
    It's the cheapest above 650w i can find and the best rated and popular on Tweakers (Dutch technology site)

    Why do you need that much wattage?

    Tell me your specs and I'll guesstimate how much it'll need.

    You'll only need 400W on that, but getting a 600W so you can do CF or that alikeon it wouldn't be a bad idea.

    You will most likely be fine with about 500W, but getting 650 could be a better investment for SLI/CFX in the future.

    For brands anyone who uses Seasonic as an OEM (or Seasonic themselves, if you want something guaranteed to not explode for a millennia) is good.

    I would recommend PSU's but I only know about prices in the UK so I might not be of any help.

    Enermax, Seasonic, Silverstone, Antec, Corsair and XFX are generally safe bets. This was just on top of my head, but there's those at least.

    Unless there is smoke coming out it's perfectly fine, it will just have a slightly reduced lifespan, most of the components inside are rated for 85-105c.

    Antec HCG-620
    Cooler Master GX-Lite 600W
    Sharkoon WPM600 An accident waiting to happen.
    I'd grab an XFX 600 watt supply, they're based on seasonic IIRC.

    You reject the ModXStream due to your one bad experience yet happy to recomend a Cooler Master GX?

    Besides, I think it was the pre-2008 OCZ's that were bad, they fixed/improved their PSUs after then.
