Yay!

Push the power button and nothing! Nadda... Zip. No fans, no beeps, no clicks. I tried all the obvious stuff without opening the case and I have a power supply tester, so next post will be after I take a look inside, which will be later, for I need to run some errands.

Wish me luck!

be careful with the PSU. Even with them disconnected, they still hold charges.
 
Which manufacturer made it?

I believe some of the more reputable companies will send you a replacement if it's still under warranty. Sometimes they'll even send you a newer, better model.

No worries on me being careful. I'm not going to open the PSU or anything - just going to unhook it from everything and then plug the tester into it. The tester will tell me right away if all lines work, what voltages they are (and should be) and if the Power Good Signal is, well, good.

A quick observation before I begin:

The blue LED in the PSU is lit as if it is powered off. The PSU has a dim blue light when off and a bright blue light when on. So it's getting power from the outlet and/or surge protector.

A set of USB speakers is getting power from the machine over the USB ports. I have way more USB ports than on my wife's machine, so her cheap-o speakers are plugged into mine.

The amount of power needed for both is very minimal (a few watts according to the meter). I'm guessing that it is (in this order): A) a loose connection someplace B) a bad power good signal C) a fried motherboard or D) the power button in the case went south.
 
Dead power supply.

Plugged it up to the tester and everything but the 5V standby was faulty (which would explain usb power). So I missed my initial diagnosis, I'd forgotten about the 5V standby until I used the tester.

Anyways, off to buy a new power supply and hope that it didn't take anything else out with it (the surge protector is telling me it has 95% of it's life left and the "protected" light is still going - but it's still possible that the PSU went nuts and killed the box anyways).
 
What kind of graphics cards are you running? I would recommend a Corsair psu, I use a 750W Corsair for my 2x 8800GT's -- gobs o power

I'm with Sn1PerR about Corsair PSU's. They're fantastic! Powerful, stable, and very quiet! :)
 
I have an 8800GT 512. I was using a 650W SLI ready one from Rosewill - obviously I won't buy that brand again (although when I bought the thing it was a decent deal for a decent brand).

I'm looking at something at least as beefy, if not more. I would like to keep the purchase price around $100. I have a few in mind, although if you have links to products at Newegg, I'd appreciate it.
 
My recommendations are as follows:

Coolermaster (Acebel)
Fortron Source Point
PC Power and Cooling

Cooler Master:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171035
Price: 109
Power: 500

Not much info on this one. Cooler Master doesn't even have it listed on their site yet. It does have a major downside though.... it's modular :\

http://www.newegg.com/Product/Product.aspx?Item=N82E16817171023
Price: 109
Power: 650

Alright, this one has a decent set of connectors (although it only uses 6 pin pci-e and not 6+2), all mesh wrapped with decent length. I wouldn't suggest using it in a super tower though. (Antec 900, Thermaltake Armor...) Best part is that it's not modular!


Fortron:

If I remember correctly, their PC div. operates under a new name: Kingwin. You won't find anything on Newegg to back that up. Back when they made the switch, their retail packaging bared the FSP logo in the front corner. Don't know if that is still the case. They are a bit out of your price range though.(either way above or way below 100 bucks)

PC P&C:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005

Price: $199, on sale for $95 and it has a $35 MIR
Power: 610

Here's a sexy beast for you, and for that price! Hellz ya, I'd buy that in an instant. You are not going to get any better quality the PC P&C. Best PSUs in the industry. On top of that, they are not modular, and should have ample cable length for just about any case.





One last thing, modular fails....
 
If you want something that will last for... well, longer than you, PC P&C is your best bet, although it is more expensive than almost every other company's psu's....

I use an OCZ silentxtream 600W with a 4870, and all the usual pc goodies, and it runs perfectly, and ocz's are usually cheap after rebate, so id give ocz a look ^^
 
I would go with a pc power and cooling just for the main fact that their not modular. Modular power supplies have a lot of resistance at the modular connections and therefor you don't get what you pay for in the long run. PC power and cooling power supplies will last longer then you do.

The PC Power and Cooling 610W.

Anyways - let's pray that nothing else went south when the old one died.

And for those who may not have one, get a PSU tester. Worth every penny every time I have to use it.

Thanks for the input guys, I was leaning towards a PC Power or Corsair, I just wanted some input from guys I can trust (you).
 
Unfortunately, that may be a very real possibility. The last PSU I had die on my took out my mobo and CPU. I got the mobo replaced, but AMD refused to warrant my CPU. It was so heavily damaged that the core was starting flake apart(a sign of overclocking to many). 30A of 12v current aren't your best friend when a faulty connector trips.

I only buy OCZ now cause they have a 5 (FIVE) year warranty on their PSUs. :)

hehe yeah with ocz you might need that warranty. they only make good memory and some decent coolers.

Id say stick to the companies that made their name off of psu's (thermaltake, antec) maybe corsair now. i have a corsair 1000w and it seems to work fine.
