I really need some good advice on my PSU rail droop problems/PSU replacement options
I'm having some rather serious voltage rail drooping with my Antec TruePower 550W PSU. I took the time today to test my rails under load (machine fully overvolted and overclocked) with a multimeter, and was really shocked to see how low my rails are drooping.
My PSU's specs:
5V - 40A
3.3V - 32A
12V - 24A
Under load my rails droop to:
12V droops to a loaded low of 11.88V
3.3V droops to a loaded low of 3.22V
5V droops to a loaded low of 4.8V
My machine is running 100% stable right now, even when overclocked/overvolted to the degree that these rail droops were tested at; so the rail drooping doesn't seem to be compromising my stability right now, although it is almost certainly compromising any attempt for more overclocking.
Here's a list of every single overvoltage in my system that I can think of, as well as every single power-drawing component I can think of:
128 Megabyte ATi Radeon 9800 Pro
Mobile 2600+ Processor
Abit NF7-S 2.0
512 Megabytes of RAM
1 X 40 Gigabyte Maxtor Harddrive
1 X DVD ROM Drive
1 X CDRW Drive
5 X 120mm AOC Aluminum fans on 9V
1 X 120mm Panaflo M1A on 9V
2 X 80mm AOC Aluminum fans on 6V (baybus)
1 X 60mm fan on 6V (baybus)
1 X Swiftech MCP600 on 12V
1 X Dual Temperature Probe Panel
1 X Floppy Drive
CPU VCORE Voltage - 1.9V
GPU VCORE Voltage - 2V
GPU VDDR Voltage - 2.85V
AGP Voltage - 1.6V
VDD (NF7-S Chipset) Voltage - 1.8V
VDIMM Voltage - 2.9V
Now for my questions. Is this PSU inadequate for my current setup? The 12V rail doesn't have a ton of Ampage to it, and the 3.3V rail is heavily stressed by my heavily overclocked and overvolted graphics card, as well as my overvolted VDIMM.
What kind of options do I have for replacing this PSU? My financial situation is terrible, to put it bluntly, and I'm very reluctant (although I *can* afford it) to buy a new ~550W PSU for a large amount of money if it isn't going to give me some serious stability on my 3.3V and 12V rails in particular.
Any advice is really appreciated, especially on good replacement alternatives for my TruePower 550W.
