Not using recommended PSU..

[ch3w2oy]

Can this cause problems when trying to RMA? 

 

Like if Gigabyte or MSI recommend a 750w PSU for their GPU and you use a 450w that is sufficient with your system, can they deny an RMA?

 

Genuinely curious.. Thanks!

Since there's no way to tell, I don't think so.

Nope. Recommended just means what the card's manufacturer recommends using, it doesn't mean that you need to be using that wattage PSU.

If a 450W is good for your system's needs then use it all you want, the card's manufacturer has no way to tell what PSU you were using.

Nope. But if the GPU isn't getting enough power it may not be acting up because it's faulty. Are you 110% 450W is sufficient? How old is the PSU, they can lose a few watts of the years?

That was just an example. I was using a 650w G3 before I upgraded my PSU to a 750w P2. I don't know about Powercolor (my brand), but Gigabytes liquid 64 recommends a 1000w PSU. I know thats insanely overboard, but it's what they recommend. It just got me thinking because I never checked the recommendations, I just went with what I researched.

What if there's a power issue or something (not sure what's possible, honestly), they won't ask for proof of the PSU you're using? Can't a PSU take other components down with it? The GPU manufacturer won't care what caused its failure? 

 

Sorry if these are stupid questions..

Yeah, that's dumb. 550w would be fine for a V64 and 9900K

It *can* but if it's not a fireball Raidmax then that's pretty unlikely
