periodically, and more often than not at the end of of a system boot my PC churns out what seems to be an endless supply of colourless fumes/smoke. I can definately smell and feel it as the air is generally thicker.
I'm convinvced it's the Power Supply Unit at fault, but not knowing an awful lot about PCs I'd prefer not to splash out on a new one and find out how wrong I was, so I guess I'll turn to you lot
I am using an MSI board and running the PCAlert program I occasionally get a warning about my voltages. It's usually the one 12+, marked red and below that number.
current numbers are: 1.74 (VCore), 3.09 (3.3v), 4.81 (+5), 11.82 (+12). Now I'll admit I have no idea whether that's good, bad or normal but as the PSU is a leftover from a previous machine I'm inclined to believe it's the culprit.
CPU temps are around 40-50, 30-47 for the System.
Am I right in thinking that this could be the PSU's fault, and if so is there any risk of damage to other components, or anything else I should be worried about.
In particular my WesternDigital 80GB HardDisk which tends to make a whining sound/revving sound now and then (previous WDs didn't produce this noise).
I'm looking into getting an Enermax PSU to replace the current one which is a mercury 300W (20a, 30a, 10a listed on the side if that means anything)
Any recommendations as I'll be hoping to get one cheap and so want to avoid making the mistake of getting a low quality version.
While PCAlert shows only the +3.3V line being too low, the accuracy of such programs cannot be trusted because the voltage sensing hardware built into motherboards isn't very accurate itself. But Mercury is a brand from Deer, a company with one of the poorest reputations in the power supply business, and I would not want to risk my computer or data to any of their products. Also if your MSI motherboard has a 4-pin square power plug in addition to the 20-pin plug, it may be consuming over 8A from the +12V line, meaning the Mercury's 10A rated capacity for this voltage will leave little capacity to run the motors of the hard, CD, and DVD drives. Replacement with an Enermax, Antec, Fortron, or Sparkle would certainly be worth considering.
My system specifications are: 1700xp, 512Mb, GF4ti4200 & 2 case fans with an MSI KT400.
I plan on upgrading the graphics card with either one of the latest FXs from Nvidia or an ATI, and I use USB Keyboard/mouse/modem.
You want a cheap, GOOD, Power Supply? Check out the 'Fortron FSP 350'. They're 32 bucks over at Newegg. Peak output is 440W. If you've got a little more to spend, check out a 400W+ from any of the named manufacturers. Antec, Enermax, Fortron, etc. A search over at Newegg will give you a good idea on prices.
I think that's likely to be a misprint. I have the last Enermax, it's a great performer and very quiet. Be careful about the exact specification differences between the FMA and FCA models, check their website for details.
