Noticed this earlier but the rebate pdf is not found. Fry's seems to have this issue on a regular basis.

Also no free shipping as of now.
 
Heh, I was kind of excited because my dad needs cheap quality PSUs with PFC, according to newegg though this PSU does not have any kind of PFC and efficiency is >70%, not a very good sign.
 
Normally we shouldn't skimp on the PSU for overclocking but I had an old computer's PSU die on me this morning... and this deal ends tonight!


Credit to FatWallet's LOTL for uploading the rebate form which is dead on Fry's web page even through the deal has one more day (today) to go: http://www.bigupload.com/d=L98F1HCO30


Thanks original poster!

 
PreyHunter, thanks!
Dang, offer expired:
"Purchase Cooler Master eXtreme Power 500 with receipt dated between 10/03/2007 and 10/09/2007"
 
Outpost/Fry's is reliable with same day shipping.

This may be of use to whoever sees this item on sale again: I got it & can confirm that this model is OK and is probably being sold at a discount because it had a production flaw where the big fan was hitting the grille causing the noise.

Took the fan grille off and all's quiet.



Off topic: There were additional problems at boot up on the system I installed this on where Windows XP would continue to load to desktop only after pressing CTRL+ALT+DEL. I saw the system clock showing 1999 just before switching to 2007 at startup so sure enough it was caused by a dead motherboard battery, new one solved the problem.
 
AVOID THIS POWER SUPPLY

I bought this PSU at Fry's the same day that I bought a new motherboard (Abit KN9-SLI), hard drive (Seagate SATA 500GB), and RAM (Phoenix 2GB DDR2). XP SP2 installed fine and the system worked fine for about a week and then I started getting random reboots, attempts at installing a game (World In Conflict) and an XP-reinstall made me realize that one of my sticks of RAM had gone bad and Memtest86+ confirmed this. I am pretty sure that the PSU damaged the RAM because now all of a sudden,

1. Using my good stick of RAM (which passed all tests), I get system freezes when 2 IDE devices (320 GB HD, 8x DVD Burner) and 1 SATA device (500GB HD) are attached to the system.
2. Using my good stick of RAM the system works fine (no problem with installing games or large file copies) when only 1 IDE device and 1 SATA device are hooked up.

Unfortunately, I already sent in for the rebate, so I can't return it (hopefully I get the rebate). I plan to sell this PSU for $10-$15 for use as a 250W power supply, which it *should* be able to handle. Before anyone gets on me about bad power at my house, this power supply was hooked into a small APC UPS, so the power can't have been that bad.

I am 80% sure it is the PSU because of all the components I have in the system
-Phoenix PSD22G800K PC6400 DDRr 2GB - http://www.newegg.com/Product/...0220091&Tpk=PSD22G800K
-Maxtor 300 GB (got at Fry's last year, don't have the model number, pretty sure it is this one: http://shop2.outpost.com/produ...r:SEARCH:MAIN_RSLT_PG)
-Seagate Barracuda 7200 500GB ST3500641AS - http://www.newegg.com/Product/...148136&Tpk=ST3500641AS
-Abit KN9-SLI AM2 mobo - http://www.newegg.com/Product/...6813127236&Tpk=kn9-sli
-AMD 4800+ 65W - http://www.newegg.com/Product/...03778&Tpk=ADO4800DDBOX
-CoolerMaster extreme 500W PSU - http://www.newegg.com/Product/...aster%2beXtreme%2b500w

The power source seems to be the only cheap component (at $10 after rebate)
 
Heh. If you say so. I checked the auto-config settings for the RAM in the BIOS when trying to track down the problem. Voltage and timing were all set correctly.

Even if it was the RAM, then it wouldn't explain why removing an IDE device made the system stable. Sorry dude, all the empirical evidence points to a bad PSU. Don't forget that I ran the machine with a stick of ram that passed Memtest86+ just fine, but still had the system freeze when two IDE devices were hooked in.

I don't know much about Cooler master, but the particular PSU I got seems to have amperage issues.

 
It was a bad PSU. I bought an Antec 500WPSU (modular) and my system is now stable and working properly.

It cost $109, but at least it won't damage system components.
 
Went to Fry's this past weekend to replace the Cooler Master Extreme.... the service clerk tried to tell me that there wasn't a problem with the PSU, but I knew better.

When I went back to the components section to find a replacement, I noticed 3 other open-box PSU's of the same exact model for sale.... so apparently I am not the only person who has had a problem with them.

They are also back to the normal price of $50. Caveat Emptor!
