You'd attach the PCI-E adapter to one of your 4-pin HDD Molex plugs, most adapters have two plugs on them to allow as a pass-through so you don't "lose" a plug.

Ok. Managed to fit the thing by arranging the HDD.
GTA V automatically set new settings at 1080p with everything on high, sliders maxed out and textures on very high. 55-60fps. Wow. But after a while ingame I had a system restart that worries me as it seemed the gpu failed somehow. Run Afterburner and set the Fan to user defined. Played for 20+ minutes and everything is ok. There's a cracking small noise from the fan I guess that I don't like though.
The gpu is pre overclocked so the system restart may happened because of the OC memory clocks or voltage failure.
Should I return the clocks to default or wait for now?

Are you sure you removed all your old drivers before you installed the new ones?

I had the latest 15.4 beta already installed. I didn't uninstall it though before applying the new gpu. Do you think I should uninstall and install the drivers again?
I'm also thinking if the OC cpu causes the reboots. I don't see a VRM issue or a PSU one.
Last resort will be to go to reference card clocks for my GPU I guess?

Ok. Observations so far:
- Went back to default clocks for the CPU. Played GTA V without problems/ PCars reboot pc after 30 minutes. It's just not restarts. It shutdowns and then starts up again. Strange.
- Switched to 850 core clock for the GPU (it was pre overclocked at 972) and forced constant voltage. No problems so far.
- Now switched to 933 reference card clocks for R9 280. After 30 minutes no problems with PCars.
As expected the CPU is stressed but the bottleneck is minimal.
I saw that the CPU idles at 54-55 C and that's a bit high. The fan must be dying.
Do you think the CPU is stressed so much that after a while causes a VRM shutdown? Or is it a voltage issue?

It definitly wouldn't hurt to try.

I think I have finally isolated the problem and it must be the PSU. It's a Cougar 650W but it only has 17A on the 12v rail. The AMD R9 280 requires at least 30A on a single 12v rail.
That said, in very demanding games like PCars I experience shutdowns and automatically restarts.
Strange that I can play GTA V for a couple of hours without a single reboot (I had 2 reboots though in GTA V. PCars reboots the system every time.
Other games like NBA2k15 work without problems.
Skyrim reboots when I raise the MSAA values.
Have I got it right guys or is there something else happening? I'm not a hardware expert but isn't it more demanding games=more power needed from PSU?

No, it cannot has 17A on the 12V rail. Maybe you mean on one of the 12V rails, but even then with a quality psu that should not be an issue since you should have 3-4 12V rails rated at 17A for a 650W PSU if my maths are ~right.
Not sure that is the case with yours...

Swap the PSU if its the RS model or enjoy from the fireworks. You can run that system with like 450W quality PSU.

Nope, it isn't. It's a simple Cougar 650W model back from 2007!
Still, R9 280 specs state that I need at least 30A on a single 12v rail.
Current PSU has 17A +12v1, 17A +12v2, 17A +12v3 and 17A+12v4. Are these enough to supply the GPU?

Yeah but they always overshoot those requirements taking into account shit PSU's.
If the PSU was good it would be more than enough IMO, pretty sure that there are people here with similar PSU's running cards like yours or even more power hungry cards.
I'm not 100% up to date but most of corsair's PSU's always are pretty good (most of them are/were seasonic designs, so it makes sense  ).

Yes, very much so. nV/AMD recommends so much amperage on a "single rail" because it has less signal interference and is a more dedicated power stream, but multi-rail PSUs have been a "thing" for god knows how long now, you can safely total the amperage across the rails and it won't matter. At least, not as much as it used to matter. You have, effectively, got 68A on your +12v .. and that is more than enough for any card on the market today. I actually believe you could XF a pair of 280Xs and not have much trouble, IMO.
... though I obviously don't recommend it

What should I do now? Is there a way to total/sum up the 4 rails so the gpu has enough power? Or is it done already automatically?
From what I understand, with a 6-pin and 8-pin power cables to the gpu I'm now at approx 34 amp (17A+17A) which may not be enough considering the age of the PSU. So, when the GPU demands more power in games like PCars I have the whole PSU power down!

Nope, doesn't work like that, 68 x 12 = 816W on a 650W PSU 
I'd say that he has around...48-50A effective? Maybe even a bit less.

Oh wtf. I just noticed that PSU fan is dead...  |
Shiiiiiet time to power down ASAP and buy a new PSU before you damage your system.

is not cheaper to replace the fan ? is not like is rocket science to replace it, especially if you have a pricy psu.

Doesn't the average PSU lose around 10% efficiency every year? It could even 20%, so yeah.. 8 years; replace rather than fix.

ah, i missed the 2007 year, i know i intended to get that psu (or something which sounded like) some time ago and was around 70 euro, but i settled for a modular inter-tech.
yeah, replace is better.
