Test 2, when plugging in the power cord, you should hear a small mains arc at the power cord socket. Press it, if you get no lights (next to button) at all, the ONLY conclusion you can rely on is it is 90% the 240vac inlet. test 1, there is a tiny white diag button on the logic board, dead centre behind the memory caseing. one dead A1186 PSU, which I'll repair tomorrow (is midnight right now) - I'll post my answers/findings shortly after, HOWEVER, even without taking it apart, I can already tell that the fault on mine is on the 240vac inlet side (2 tests. NB there is a theoretical risk of damaging the capacitors during discharge, although I've never known it to happen. A small 'tick' noise will be heard the first time you discharge, the second time there will be no noise, this being your evidence of a completed discharge ALL OF THE ABOVE IS WRITTEN WITH THE ASSUMPTION THAT YOU HAVE ALREADY DISCONNECTED THE MAINS SUPPLY. DISCHARGING: to make-safe the unit it can be actively be discharged by the deft employment of the end of a sizable flat blade screwdriver, and shorting out the 2 terminals on each of the capcitors. It’s been 17 months since Apple introduced the original Mac Pro, which shipped with two dual-core processors (an 8-core model with two quad-core CPUs was introduced in April 2007), and the new Mac Pro is a big step forward: every configuration uses quad-core Intel Xeon CPUs for even more power. IT HURTS LIKE A B!TCH!! Anyone with heart problems may want to re-evaluate thier decision to work on an undischarged unit. Mac Pro (Early 2008) LEM Staff - 2008.01.08. What does it feel like? I can only speak for the 240vac version, and have this to say about it. i.e it exists transiently until the caps discharge. if its th USA model, that slim chance is even slimmer, as the USA uses a girly 120vac as oppose to our manly 240vac in the UK. as yet there have been NO recorded occurences. Welcome to never ending progress and never ending dissatisfaction.ġ: The likelyhood of the belt delivered by the smoothing caps in one of these being fatal. No one cares anymore and they just are waiting for us to shell out the cash for a psu which could probably be repaired for ten or twenty bucks. Obsolescence and customer-obliguing tactics are the norm. Technical progress has become only a money drain and a huge waste of otherwise repairable units. No one wants to determine the real culprit because mos people are better off selling you a 200 or 300 bucks replacement. They put us through all this this hoops because they want us to obligue and not use our 2008-2010 MacPros anymore, they need to make a profit from us, they need to get us to buy a new “umbrella-cube” 3k-4K machine just because.ītw, it’s all about the soldering quality from factory, the damned relay switch inside the PSUs, and/or the temp sensor &^&^$^ with all the security settings for switching it off just because. Please take the Pro nickname out, it’s not deserved. It’s all been a money drain since Steve Jobs left us.Īpple is no longer a winner game, it’s all bells and whistles but they don’t care about the power going to their MacPros. We gulp this and cope with this because of a brand’s undeserved reputation.

#Early 2008 mac pro power supply for mac
Almost always just after the period PSUs, I guess Delta (the provider) is using monkeys in the soldering plant at their factory.Īnd eBay sellers are just making a profit on selling replacement units that maybe are just refurbished units that will fail also given enough time. This product includes: Power Supply 980W for Mac Pro 8-Core 2.8Ghz-3.2Ghz (Early 2008).
How can they dare ship MacPros with these dodgy PSUs, and won’t get them replaced, they’re so smart as to never ever let them die within the guarantee period. They would need to have been properly flowed in the soldering process at like this is what makes us lose faith in Apple. Use the following table to interpret the LEDs.These particular PSUs fail because of bad factory work.
To press the DIAG_LED button, use the nylon probe tool ( Apple part number 922-5065). To read LEDs 1, 2, 7, 8, and 9, you must press the DIAG_LED button, which is adjacent to the LEDs. LEDs 3, 4, 5, and 6 are normally off and will automatically illuminate if an error occurs. The LEDs are located on the logic board between the two DIMM riser card connectors. The Mac Pro (Early 2008) logic board includes a set of LEDs to help service providers troubleshoot the computer.
