compatibility or just plain bad. I would ask for my money back.
I recently upgraded an old (still working) Enermax 460W PSU[model EG465P-VE(24 pin)] with a brand new Apevia 680W [model ATX-AS680-BL (20+4 pin), a.k.a "The Beast"]to accomodate a NVIDIA GeForce 9800 GTX+ Black Edition video card. The mother board is an ASUS P5ND2-SLI Deluxe,socket 775, Intel Pentium 4, 3.40GHz, 4GB DDR2 RAM. (The reason for my PSU upgrade is because the new video card requires two PCI/E 6-pin power connectors (for optimum performance), while my old PSU has only one.)
So I've got the new PSU out of its box and hook up my tester to test all the leads (I'm pretty meticulous in any PC building, especially when it comes to hardware. And while changing PSU's is pretty straight forward for me, I don't always do it with my eyes closed!)and they all test fine. So I disconnectd the old PSU and connect the new one...the pretty blue PSU lights up, momentarily powering up the CPU fan, then shuts down. What? Is everything hooked up? Is it all properly seated?....Unplug everything and start over from scratch, just to make sure...(let's just get her to POST)
1. Main PSU Switch_OFF.......check
2. Main 20+4pin MB...........check
3. Auxiliary 4pin 12v........check
4. Keyboard, Mouse & Video...check
5. Main A/C Pwr Cord.........check
6. Holding breath............check
7. Main PSU Switch_ON........check
8. Power PC_ON...............success, Houston we have POST!
OK, now everything is cool,right? Ghosts in the machine, negative ions floating about...all taken care of....I've done it hundreds of times.
But now, after I'd removed the old PSU, installed the new one, routing all cables and connectors like an airflow pro, made all connnections firm and sure...BUZZZZZZZZ!!! She kicks right back off! No beep, no post...just pretty blue PSU lights flickering on and off in the space of a billion and a half nanoseconds.....!!!GRRRR!!!!
Circuit breaker? No. Exsposed/Shorted Circuit? No. New PSU Faulty? No(I rechecked). Did I burn something out, MB maybe? NO! (The old PSU still powers up the PC just fine!) Apevia tells me its a compatibiltiy issue and to..."Check with ASUS",(yeah, I called them)!
NVIDIA's site just plain directed me to ASUS...period! No other support offered by them other than directing me to another site. By the look of the age of the threads there though, I'm not holding my breath! Anyone have any ideas what may be going on here? I'm 50W above requirements, but I can't even bother to install and try the new card till I can get the old system booted with the new PSU.
