Hopefully just a riser, but that series of cards definitely has some age, and MilkyWay is going to tax them more than most work. How old is it?

I found a seller who had apparently not looked at the prices of other HD 7990s. My "new" Sapphire Radeon HD 7990 for $187.50 with shipping will be here by Tuesday, 22 December. Merry Christmas to me!
The seller has more than ten cards at this price!

Seems like a great deal as long as the seller is good. I might buy one myself but I don't have a system it would fit in.
The replacement video card looks brand new and runs cool for a Radeon HD 7990 at 72C loaded. I however found that I have a bad
OCZ ZX Series CPU EPS 4+4 PSU Modular Cable. I don't know which one of 2 is bad, so I bought two new OCZ cables on eBay. I will continue to run three of the four video cards and hope to be back to full capacity by 28 December. If my "bad" video card is not bad, I need a third power supply and two more cables to run five video cards.

I dug through some video card boxes and my Kennedy tool chest/parts storage. I found a two 4-pin Molex to a 6-2 PCIe adapter and determined which of my two cables was bad. The computer is back to 100% with four Radeon HD7990s. I have taken some wattmeter readings on both power supplies and figure that I can reconfigure my system to run five video cards when the two new 6+2 PCIe cables get here from eBay. It will take me about thirty minutes to reconfigure. I plan to run three video cards on the 1250 watt power supply and two video cards plus the motherboard on the 1000 watt power supply. That configuration should get the rig up to about 4,000,000 points per day.
This is how an old man gets another video card: Presume the worst, buy another video card and work your way down to the correct failed part.

Two video cables are coming on Monday and I hope they work right. I need four, but wanted to see how these cables from modDIY.com work before I get more. The delivery has taken a month from Hong Kong! They spent four days in Chicago and three days in the Washington, D.C. area (Maryland). They have been about 40 miles away for three days where they have been listed as "departed for delivery" three times. You have to love cheap shipping and the United States Postal Service.
My RAC has suffered through thousands of "invalid" results on stripes 84 and 85 work units. Tom Donlon said credit will be given later. We are hanging in among the top teams and should get to second place if I can ever get my rig running all five video cards (ten GPUs). Bring on the Radeon VIIs and whatever you have, team!

The two new cables from modDIY arrived today and I have installed them. The modDIY cables look better than the originals. I have ordered two more for the fifth video card.
I suppose I can say that I am back to 100% since I am running four Radeon HD 7990s again. When more cables get here in a few weeks, I will try for a "new normal" with FIVE Radeon HD 7990s.

The power supply fan is a simple case fan and it is easy to replace.
The mining rig is running four video cards again. I concluded that I did not have a hardware problem after reconfiguring the rig (five video cards and two power supplies) in various ways. I did a clean installation of Windows 10 Pro and it seems to be fixed. The new installation of Windows did not respond well to my wireless mouse, so I changed to a wired mouse. After updates and personalization, I installed motherboard specific drivers, HWMonitor, Radeon Blockchain Beta drivers, and BOINC MilkyWay. I am running three WUs per GPU with app_config.xml and I replaced boinc.exe with version 7.15.0.

The rig is back to 5th place among computers and I believe it will go to 3rd. Our team is poised to overtake Planet 3DNow! for 3rd place.
We are now in 3rd place, but we didn't pass Planet 3DNow! Sicituradastra fell from 2nd to 4th place.
I bought another 1000W power supply and will add the fifth Radeon HD 7990 by Tuesday of next week, 23 Feb. I bought the 1000W power supply "just in case" I am compelled to fill the rack with a sixth video card.

My rig is running four video cards, eight GPUs running five work units each. I cannot keep my queue full enough to run 40 work units at a time. It doesn't seem to affect others in the top computers list, but my computer runs out of work and sits idle.
I am running BOINC 7.15.0 already. It seems to me that they are running out of work units. No one has complained at the Milkyway@home forums.

They have been working to fix the issue and updating us on it in the news section of the forum. They've gone through so many work units they ran out of database ID numbers which brought everything to a full stop about two weeks ago. Work arounds have lead to other issues and it's just going to take time before there is an endless amount of work again.
