Rampage V Extreme issue with Thermaltake XT TPX-1275M, XT TPX-1375M, & TPX-1275M

[QuinValen]

I have found no postings or knowledge online that indicates any incompatibility of these power supplies and the Rampage V Extreme. I would like to know what is causing the Rampage V Extreme to react badly with these power supplies; and prevent others from having to go through similar frustrations.

I am also asking for good advice on what PSU to consider next, though I have always used Thermaltake and never been let down. The QVL lists the TOUGHPOWER1500A; which one is this: Toughpower PS-TPD-1500MPCGUS-1, the W0171, or the TP-1500M?

I really don’t want to move away from using Thermaltake (been using for over 10 years), and if do so, what is the best option for a minimum 1350W load? (I already have totaled at this point $900+ USD on just PSUs, and now also out of pocket on all return shipping.)


The Story:

With the Thermaltake Toughpower XT TPX-1275M, XT TPX-1375M, and XT TPX-1475M and two separate Rampage V Extremes random shutdowns (time varies between instant shutdown/fail to POST, or up to 30 minutes of uptime. The BIOS POST reports shutdown was due to power surges and/or unstable power supply on reboot. This occurs on box builds with only keyboard, mouse, video, and monitor attached. Attempted also utilizing both AMD and NVidia video cards (5 different cards, 4 separate models). Keyboard and mouse were also swapped out. This has happened on BIOS versions 1401, 1502, 1601, 1701, and 1801. Fully cleared and reset all BOIS settings on each attempt. All three power supplies were utilizing either an APC Back-UPS Pro 1500 or a 1500 XS, or straight to source/wall power.

However after installing an old Thermaltake TR2 RX 850W the Rampage V has no problems at all. Ripping out the TR2 RX 850W from my wife’s Rampage IV system after 2 motherboards (already reordered another Rampage V and was set to RMA the first as defective) and 3 power supply replacements proved unsuccessful, I tested all three of these power supplies with burn-in /high load testing successfully on runs of 24 hours my Rampage IV without fault. I started this after the second motherboard and power supplies failed in reverse order of testing.

Only the old Thermaltake TR2 RX 850W (previously utilized on my Rampage IV Extreme /2x XFX AMD290X system) is working with the Rampage V Extreme but it is barely able to meet my power requirements From limited overclocking and testing with only 2 GPUs that the Thermaltake TR2 RX 850W is drawing too close to maximum wattage (850-870W) and preventing me from using a 3rd planned GPU or to really attempt any overclocking at this point.

I contacted Thermaltake themselves, they were awesome and RMA'd the 1475 for a 1275 in hope it would resolve this issue; while it unfortunately did not, I am going to utilize that 1275 for the older Rampage IV as it has no other power supply at this time and has no problem with it.

Current build with the TR2 RX 850W is:

There are too many variables in this to troubleshoot it correctly. I would eliminate one variable at a time. Fiirst, if you have a good power supply like
Thermaltake TR2 RX 850W and test the motherboard as it is. Please do a stress test. If motherboard POSt okay with power supply, the motherboard is is working properly. You can put check mark on the motherboard. Please make sure the motherboard is stable before you test other components.

Next variable is the power supply, test one power supply at a time.
First, Toughpower XT TPX-1275M, second XT TPX-1375M, and third XT TPX-1475M.
Test Thoughpower XT TPX-1275M on Rampage V Extreme with all pins connected to the motherboard (I mean all), and make sure the thermaltake water cooler is plug and power on. Do the same stress test again.
Do it for the next two power supply

As far as troubleshooting I eliminated variables one at a time:

This occurs on box builds (2 different RVEs) on with only keyboard, mouse, 1 GPU, and monitor attached; no other variables to include not using the 3.1 PCI-E or the OC Panel.

Utilized AMD and NVidia video cards (5 different cards, 4 separate models one at a time and in multiple video PCIE slots).

Also swapped out keyboard, mouse, monitor, and the RAM DIMMS (Corsair Vengeance & G.Skill Ripjaws), both in whole and in part.

I stepped through using the XT TPX-1475M (2 different ones!), second XT TPX-1375M, third and last was the XT TPX-1275M were used in process of elimination on both RVEs. All three power supplies were utilizing either an APC Back-UPS Pro 1500 or a 1500 XS, or straight to source/wall power. All cables were replaced with each unit and variations of the Video power sources were used (6-pin/ 6 & 8 pin, and 2 GPUs with none). All these power supplies had no issue at all when tested on the Rampage IV I have on hand.

The BIOS POST reported "shutdown was due to power surges and/or unstable power supply to prevent damage" on reboot on versions 1401, 1502, 1601, 1701, and 1801. (Fully cleared all BOIS settings after each flashback load)

If surge protection was turned off in the BIOS the RVEs would go into boot loop about 6 of 10 times on reboot.

Only power supply I have that works with the RVEs is the TR2 RX 850W that I have at this time, as I am out shipping and restocking fees for 3 premium power supplies, and can't just order another for some time.

Mostly wanting to know why, I am not an electrical engineer and don't have the equipment or what to make of the measurements off the RVEs if I did.

A main purpose of the post and its detail is to learn if any others had frustrations with the XT TPX series, and to expand our knowledge/experience.

Did you populate the 8 pin power header on the motherboard during your tests? And if you're using multiple GPUs, be sure to populate the EZ PLUG header as well.

Regarding PSUs, I personally use the Seasonic brand for all my builds. I've used many of them with the Rampage V Extreme without problems. The models are Seasonic 1200W Platinum, the Seasonic 850W Platinum and the Seasonic X 1250W.

Yes, the 8-pin & 4-pin CPU connected and the EZ-Plug too.

It just seems weird to me, and hate to move away from Thermaltake as I have been using them and ASUS boards exclusively since 1997.

I don't understand why they wouldn't be compatible but after you tried 3 unsuccessfully it's time to switch. I have a Corsair AX1200 and AX1500i and a Seasonic X1250 that all work perfect with the RVE, the EVGA power supplies are receiving very good reviews and they have 1600 watt models

Did you ever try the Toughpower XT TPX-1275M, second XT TPX-1375M, and third XT TPX-1475M on another motherboard to see if they are functional and working properly?

Yes, on another Rampage V, a Rampage IV extreme, and a Maximus Formula.... The Maximus and the Rampage IV Extreme have no problems with any of the XT TPX series I have tried, only the 2 RVEs.

Did you also plug power on both EATXV12_1 and EATXV12_2?
