This is sort of a continuation from my last post here. I own a Dell XPS 435 MT, and it wouldn't power on one day. We figured out that it needed a replacement power supply. Now, after a game of League it randomly shut down, the power light on the front is just glowing amber, the motherboard light looks fine, too. I'm not entirely sure what is going on. Any ideas, everyone? I'm hoping it's just the power supply again.

Did you purchase it locally? Or order it from Amazon http://www.amazon.com/Power-AGS-550W-Dual-SATA/dp/B001LJZPQI/ref=cm_cr_pr_product_top or other online store? I would have it tested as it's really not a quality PSU. Amazon as you see, has it for $25.00 & $7.25 of that is for shipping. You just can't get quality at those prices. If you find yourself again shopping for a replacement then have a look at PSUs made by Corsair, Seasonic. OCZ, Antec. Look for units that have an 80+ rating. Good units also have a bit of heft to them. Cheapos are barely adequate for paperweights. Stick with quality brands & read the reviews. Newegg.com is a good place to start.
Also, I'd give the MB a close examination for possible swollen capacitors. And while you have that side cover off, have some canned air handy & blow out the dust if needed.

It's been a couple months since I bought it, and I picked it up from a repair shop who said it was reliable. In hindsight it was probably a poor choice. Paid like $60 for it at the time, wasn't really thinking about it, but I will have to do some testing. It does seem like the power supply for sure now, and computer is freshly dusted.

Perhaps the shop you purchased it from will be kind enough & honest to test it & replace it if faulty. It appears you bought it near the end of May, not very long ago. PSU testers are also available [check Newegg & other reputable sites] at reasonable prices & probably are very similar or same as what the shop would have/use. Post back & let us know what you find out.

1. Disconnect the power lead, press the ON button on the computer for at least 10 seconds. Reconnect the power lead and try and boot up.

DANGER! DON'T DO THIS BELOW UNLESS YOU ARE CAREFUL OR KNOW WHAT YOU ARE DOING. YOU MIGHT DAMAGE YOUR COMPUTER AND/OR YOURSELF. If not confident, take it to a repair shop:
2. If you are confident enough to, try and jumpstart the PSU with the paperclip trick http://www.youtube.com/watch?v=khpnx21oydg . This will tell you if the PSU is dead (a power light glowing does not necessarily indicate a working PSU).

3. Check your power button is connected to the motherboard. If it was me I would try and start the computer with a screwdriver by shorting the power pins rather than using the button. http://www.tomshardware.co.uk/forum/305911-12-start-computer-screwdriver
