I had a few hiccups along the way in building my new box, however this issue is preventing me from even using it.
Backstory: When I first put the box together, there was one component I was still waiting on to arrive: the PSU. I had an ULTRA 550W X2-Connect on order that got delayed. Eventually, I got impatient and went to my local Fry’s to just pick up a PSU, so I grabbed a Thermaltake Purepower 600W. After a somewhat frustrating build, I got the system up and running. To note, at this point, I don’t recall having any booting troubles at that time; Windows XP installed fine, I did several reboots for drivers and whatnot, all of which went swell.
The next day, I had a failure of a cold boot. “Okay,” I thought, “I’ve had this happen before, no big deal.” Switched the power supply off, unplugged it, plugged it back in, switch it on, wait a few seconds, try another boot. Works. Okay, good.
Next day, another failure of a cold boot. Annoying, but I’ll run through the series again. However, this time it doesn’t boot. Crap. Okay, try the series again. Not booting. I try again and again and again; half an hour later, I finally get a proper boot. “Shit, maybe the power supply is bad?” I decided that I’d use the Thermaltake until my ULTRA arrived, at which point I’d swap them out and send the Thermaltake back to the store.
After a few more days of frustrating boot failures, I gave up and took the Thermaltake back to Fry’s. When they tested it, they confirmed it faulty. Wonderful. I go back to the PSU aisle to pick up another unit, this time of a different model and brand. During the days a the failed boots, however, I considered (before finding out the Thermaltake was faulty) the possibility of the power supply simply being underpowered for my system (specs at the end of the post). Thus, in order to better make sure I don’t run into more crap, I grab an ULTRA X3 1000-Watt. Overkill? Probably, but I was too pissed off at this point to care; I just wanted my damn system running.
Take it home, put it in my system, plug it in, power on… no boot. Fuck. I took it out of my system and plugged it into the wall outlet and jump started it to see if it’s my system or the PSU itself: it’s the PSU itself. Great! Two faulty power supplies from Fry’s in a row! I thought the boxes to this and the Thermaltake looked suspicious, but there was no sticker indicating it was a refurbished. Next time, I’m either making sure it’s an unopened box or having their service center test it.
So the next day, before taking the X3-1000Watt back, my X2-550Watt arrives. Joy! I’ll jump-start the fucker first to see if it’s a dud or not, considering my luck it probably will be…annnnd it is. Looking at the box, it’s probably a refurbished. Thanks, Xoxide! Oy.
Okay, so I take the X3 back and pick up what is an unopened Corsair HX-520Watt. Less power than I wanted, but fuuuuuuuck it, at this point I just want something that works. Take it home, jump it: works. Okay, put it in my system, minimal hookups (motherboard ATX 24 pin, 4-pin ATX for CPU, 6-pin for PCIE card and 4pin for watercooling system). Boots as the Thermaltake did: “boots” but doesn’t hit POST. God damnit. Maybe it’s underpowered? I’ll find out tomorrow with another trip to Fry’s.
Today is tomorrow. I pick up a SilverStone ST85F 850Watt and bring it to the service counter for testing. All lights green. Great. Take it home, jumpstart it. Works. Plug it in to my system, bare min: failure to get to POST. I am at this point too weak to even cry.
So, Great Internets, I put aside for now my years of fucking around with computer components in attempt to learn them like a Myst puzzle and come to you. As we have seen, it now does not seem to be a power supply issue. If such is the case, what could be the cause for the system to fail to boot to POST? Keep in mind that I was able to run the system fine on the Thermaltake for about a day, and after that, able to get the system past POST after half an hour of attempts. When the system did run, it ran perfectly. While I have not been able to get the system to run past POST on any of the other power supplies, I have not give more than a few attempts after the signaling failure for each one.
I am at the end of experimentation, and leave what be my next step up to you.
