Strange issues after changing PSU

[BTRY B 529th FA BN]

I recently swapped out my Enermax Revo 950 with my Seasonic X 650 Gold and things started acting up.

The symptoms are this:

The machine will power up but the system does not boot. The video card fan runs faster than normal but no screen.

What I do is simply hit the restart button right away and sometimes it will boot like normal.

RebateMonger suggested it was the bios battery. So this morning I went to get one (store was closed, came back) tried to start the machine without the bios battery and I had a few reboots until i got here.... Currently I am booted into my system (doesn't look normal) .. without a bios battery. All my settings have stayed the same (AHCI mode, DRAM voltage, nothing has changed)

Possibilities:
mb is going bad ?
Bios battery? What are the normal specs of a bios battery? 3v Lithium?

EDIT: if it is the MB, I can still salvage the Q9650 and the 8g of DDR2, but a new MB would require at-least 8 SATA ports

Some more information on your system would likely be helpful. What hardware do you have, why did you swap out the PSUs, etc?

As for the CMOS battery, it's always a CR2032.

The Enermax Revo 950 is way overkill for this system but I just didn't' see the need to swap it out until I started thinking about leaving my system run 24/7 to record scheduled TV shows.

I started thinking about a i3 530 system and I had it planned out but I just needed the PSU. And a system like that doesn't need a huge PSU (had an extra Enermax 950 laying around)

I also figured I didn't need the/my Seasonic 650 Gold in my i7 920 MTS/AVCHD NLE machine and so I figured I'd just not spend the $399.97 on a H55 i3 530 system and put the Seasonic in my 'main rig'.

The difference in the two PSUs was about 10% in efficiency savings. The Seasonic is 88.9% efficient between 60-70w then 90% all the way up to 588w. The Enermax wouldn't get that much in those low load/idle states...

Tried the new bios battery and still same shit.

Well, I put my spare Enermax Revolution 950 in and the problem went away. Strange because the Seasonic works in other systems...

Bad power supplies are strange things. They'll make you pull your hair out so don't try to understand them.

I don't rule it as a bad PSU as it does work in other systems. It works with my i7 AVCHD machine

920
6g 1333
2 15k RPM SCSI drives
2 large storage drives
2 Ultra 320 SCSI controllers
X-Fi Platinum
various fans; 120x38 (3) 2x 80mm fans

Although you may be right.. I just don't understand the symptoms it was displaying.

I had one worked fine in a Q6600 rig. Used it in a i7 rig and it was giving random reboots/freezes. It was a 650 w power supply. So I thought maybe the i7 was too much even though it shouldn't of been. Put the power supply back in the Q6600 rig and it did the same thing it was doing in the i7 rig. Not sure why it decided to go bonkers but I was stressing like crazy cause I couldn't figure out the problem cause I knew for certain it was a good power supply.

Actually I think I forgot I had this problem before... I vaguely remember it doing this.

Now, all 3 of my rigs are running Enermax Revolution 950s

The game rig will run close to 600w
The AVCHD NLE (non linear editing) machine will probably run < 350w (a little overkill)
And this main rig will brand that Enermax 950 'Overkill' for this machine; but it works and that's the main thing... I almost went and bought a new platform... glad I re-checked it with my other PSU.

I'm sure the Seasonic still works. Lets hope.
