I would like advice and opinions on an issue I am encountering.
I own a Dell Studio 540 Desktop PC running Windows 7 64-Bit with Intel Q9550 processor and Dell proprietary Motherboard. It came with a LiteOn 350W PSU -which died on me- it was supplying power to 2 Hard drives, one optical drive and a GeForce GTS 240 GPU.
I bought a Corsair CS450 M as a replacement. Installed it, it powered on PSU started, its fan running BUT Windows 7 would not start. Perplexed I took the PC to be checked by one of the leading big computer stores in Canada. They checked various hardware components and then they used their own testing PSU (a Corsair TX 850) AND the OS in my PC booted up. I deemed my CS450 M to be D.O.A. Obvious conclusion right?.
I requested an RMA from Corsair and another CS450 M was shipped to me. I installed it, once again it powered on but Windows would not start, took it to the technician, same result their PSU booted up my Windows.
I called Dell Computers to see if they knew of any possible incompatibilities with third party PSU. They responded that as long as 3 Sata connectors are plugged into the PSU and drives and the 6 sockets into the GPU, the 24 pin into the Motherboard plus the 4 + 4 into the CPU Power in the Motherboard the Computer should work flawlessly. So I ruled out PSU and PC incompatibility.
Requested a second RMA and this time they shipped an RM 450W, went through the process with the same frustrating outcome.
Called Corsair support and confirmed with them that there is no chance of making mistakes with plugging in the 2 ends of the connection cables. There is just ONE WAY possible to connect cables and as long as the 3 Sata drive connectors, 24 pin connector to the Motherboard, 6 socket one to the GPU, the 4+4 one to the CPU Power in the Motherboard are firmly secured to their sockets.
Connection issues are ruled out.
Before the original Liteon 350 W died, there was enough juice to power the hardware. Same hardware still in the PC so a 450W Gold should also work.
So having enough wattage available rules out being a problem to run the PC.
Three different Corsair units power on, fan runs but would not boot Windows up.
A fourth Corsair PSU a TX 850 powers on, and DOES boot up Windows 7 Home 64-bit. What gives?
So, what is your take on what could possibly be happening?
I have ran out of logical explanations. What am I missing out in here?
I would appreciate knowledgeable comments and opinions that could help me out to solve this strange -for me- situation
Thank you kindly
