Upgrading PSU (HP Elite e9180f)

HP Elite e9180f
Microsoft Windows 7 (64-bit)

Hello,

 

I need help in finding a new PSU for my computer, the old one gave out after 8 solid years and ran into an issue.

 

I bought a Corsair CX650 and it can only boot the gpu, mobo, and cpu, when I plug anything else in, it either just shuts off as soon as I turn it on or it'll turn on and off again constantly.

 

I spent the past month with Corsair's support and another CX650 in trying to fix the issue, but it turns out it's a compatibility issue and they couldn't figure out anything else and just gave me a refund. I even tested everything else out myself, but the pc still runs with the orginal PSU, just not very well and the old PSU ends up shuting off faster each time I try to use it. I also bought a PSU tester, just to confirm the old PSU failed every test and nothing wrong with the second Corsair PSU.

 

I planned on getting a 650w supply, as sometime after I get my pc back up and running again, I'm going to get the GTX 1080 Ti GPU.

 

Specs:

EVGA 650 GTX GPU

Seagate Constellation 2TB HDD

Original DVD-Rom and BD-Rom disc drives

Intel core i7-920 CPU

9 GB RAM (3x1GB and 3x2GB)

Pegatron Truckee Mobo

Delta 460w PSU (the original that I'm replacing)

 

Still find it strange that I ran into a compatibility issue, I always thought PSUs were mostly universeal and was just limited to size, mobo type, and wattage needs.

@vovillia,

Your computer shipped with BIOS, also called "Legacy".    The GTX 1050Ti, and in general, any GTX card above the GTX 660 will not work. These cards are UEFIvBIOS.  (There are hybrid exceptions made by MSI, and Shappire).   You have done an excellent inquiry, explained it, and listed the internals.

1) You can not convert the e9180f to UEFI.

2) I would suspect the motherboard as your problem.

Thank you for the information.

 

That's unfortunate that I can't get a better GPU in this rig and I'll run some tests on the mobo.

Hi,

 

I ran a Corsair HX 650 in the HP 9280t (same truckee motherboard) and didn't have any issues.

I have done a bunch of tests with the mobo and is perfectly fine with the original PSU, just that the old PSU overeheats.

 

I also found some old articles online about the mobo and discovered that it's very, very finicky with PSUs and only a few work correctly with the mobo.

 

I guess It's a trial and error for now.

Ok I think I got an idea.

 

I wish I could experiment with this a bit, but don't have that kind of money laying around. But I think the issue is the output at the 3.3v and 5v ranges.

 

The orginal PSU gives a continous amount of 385w on all ranges and this corsiar psu I bought only gives 130w at both 3.3v and 5v ranges.

 

So I should be looking at a psu that gives me at least 385w at all ranges?
