Can a 550W PSU handle a SAPPHIRE TRI-X R9-280X?

Ferrariassassin · Oct 29, 2014

I heard you will need a 750W to 1000W just to be able to handle it stock.

No, that's not true. 1000w is for crossfire. Any Tier 2B or above 650w PSU will run that card fine although I'd really like to see a Tier 2A or Tier 1 PSU with it. However, it does need 2 8 pin connectors, or two 6+2 pin connectors, so that's going to limit the selection.

Oh ok

Well would a XFX TS 550W PSU handle a Gigabyte R9-280X? I heard of people using a 500W with an R9-290X all the time so it should i hope.

This, would be fine for the Tri-X:

Yes, 550w XFX is a good choice for that card.

I really do not want to waste money on a new PSU. I bought the XFX TS 550W PSU to run an R9-280x because everywhere i looked said a 500w was good but now after i bought it some people are saying a 750w-1000W

so i guess i should throw my PSU away and buy another new one :? dang it this sucks

I also heard of people using mayonnaise for thermal paste, it will work, doesn't mean it's a good idea. Heh.

Ferrariassassin :

There's a big difference between an R9 280x and an R9-280x Tri-X. At least based on the Sapphire recommendations and general feedback around the forums. I've never owned a Tri-X so I'm basing that off much research but it is what it is. A normal R9 280x with a good 550w Seasonic, XFX, EVGA or Antec, to list a few, should be no problem so long as the PSU is in good condition and has the correct connectors.

Darkbreeze · Oct 29, 2014

Is yours a Tri-X?

anbello262 · Oct 29, 2014

A 550W XFX would be a great PSU for that card. What is your CPU?

I believe that a Tri-x should be about the same as a dual-x or any 280x card with 2x8 pin PCIe connectors in power terms. As it's the same card, the only difference that it could have is a beefier power circuit to be able to overclock it higher. But that's optional.
The only way it would consume more power is if it was overclocked higher, isn't that right?

DO you think the Gigabyte is the best of the R9-280x? besides the sapphire?

Darkbreeze · Oct 29, 2014

anbello262 :

For which card are you referring? Not the Tri-X right?

Darkbreeze · Oct 29, 2014

Ferrariassassin :

I like, in this order, Sapphire, XFX, MSI, Gigabyte, ASUS and then HIS. The rest are meh.

Ferrariassassin · Oct 29, 2014

Darkbreeze :

Well i ordered the msi but newegg canceled it from it being out of stock so now im stuck with the sapphire, ASUS, and gigabyte and idk what to get. I know the sapphire is out of the question but what about the Gigabyte one? WOuld my PSU handle it good?

anbello262 · Oct 29, 2014

I don't think that a Tri-x would be different than a normal 280x.
I will research more, thoguh. But as it's the same card, there should be no difference in power terms, at stock speeds and voltage...

We're talking about a 280x, not a 290/290x, after all...

Ferrariassassin · Oct 29, 2014

SO far everywhere online has said the MSI is by far the worst overclockable card and the ASUS kicks off if it reaches 70 degrees and the sapphire is extremely loud and almost all of them rattles and the gigabyte has the exact same clock as sapphire.

Darkbreeze · Oct 29, 2014

What do you mean the Sapphire is out of the question? They have 8 different models of that card, all at different prices from 249.00 up to 409.00

Ferrariassassin · Oct 29, 2014

anbello262 :

No we are talking about the R9-280x and ok thanks

Ferrariassassin · Oct 29, 2014

Darkbreeze :

If my PSU cant run it how do i use it? And i am have my mind set on the R9-280X model nothing more or less ANd id buy a GTX 780 before i spent 400 on a r9 280x

Darkbreeze · Oct 29, 2014

anbello262 :

Not, the same. The standard version R9-280x needs a single 8 pin, the Tri-x needs 2. Much different amperage requirement.

Ferrariassassin :

You need to slow down, and read the posts. This would work fine with your XFX PSU.

I wouldn't really trust this site, because I don't know about it, but just in case anyone finds some back-up for this:
http://www.pc-specs.com/gpu/ATI/R-200_Series/Radeon_R9_280X_Sapphire_Vapor-X_3GB_TRI-X_OC_Edition/2087/Compatible_PSUs

A 280x will consume about the same power at same speeds, no matter the manufacturer and cooler. If you overclock it you increase power consumption.
The only difference that cards have is the overclocking headroom. The better the card, the more overclocking headroom you will have.
But overclocking is optional.
You can overclock a bad card 5% maybe.
You can overclock a good card 5%, 10%, 15% (for example).
If your PSU can support up to 5% overclock, you should still get the better card, as it will run cooler and better, and maybe sometime you can even upgrade the system.

The more power pins it requires, the more power headroom it allows. But it will still consume the same power at the same speeds/voltages. And the Dual-x also has 2x 8pin. The XFX has 2x6 pin. Still the same card and power requirement. Only difference is overcocking headroom.
And that PSU has 2x 6+2 power pins.

Yes i know the prices friend i was meaning that my 550W could not run itbecaus i only have a 6 pin and 8 pin for a GPU from what i see

Darkbreeze · Oct 29, 2014

anbello262 :

That's accurate, can't argue that. Honestly, if I was the OP I'd return the PSU and just get one capable of running any of the models, if it's an option. BTW, I see that the Egg is out of that model I posted, so that must have been the model he first ordered.

anbello262 · Oct 29, 2014

Oh, I was sure that the xfx 550 had 2x8 pin D:

If it doesn't, then get a different branded card. Not dual-x or tri-x.
Maybe an asus one?
