Which model Corsair 750W PSU to use in a DEll XPS 435T 9000

[thmpr93]

I would like to upgrade my PSU in my Dell XPS 435T 9000. I am looking at the Corsair models but I have no idea which model to select. I have seen people recommend the CS, RX and TX so I am really confused as which would be best for me. I just want to get a higher reliable power supply that will fit into my case. I appreciate any help/insight on my quandry. Thanks...

Quality is far more important than quantity. The actual necessary psu will be determined mostly by the gpu size. If you still have the original HD 4870, then a high quality 450w to good quality 550w is all you'll need, not something as expensive as a 750w.


Power Supply: SeaSonic - S12II 520W 80+ Bronze Certified ATX Power Supply ($44.99 @ SuperBiiz)

That's more than plenty for your i7 and HD, will even handle a gpu upto and including a gtx1060 or any number of older models.

For Corsair specifically, the CXM550, TXM550 are plenty, the ultimate being the RMx550, but that's really in a class of psu far above your realistic needs.

I was actually looking at a EVGA GeForce GTX 1080 Ti FTW3 DT GAMING 11GB GDDR5X - waiting for the prices to drop. Would the 550 be able to handle that ok? Thanks for the advice.

I'd not go with a DT. Evga rigorously tests every FTW and if it fails requirements in even the slightest way, the clocks are reset to SC values and the card is sold as a DT. So while you pay for a FTW card in looks, custom pcb, cooling etc all you really get is an SC performance.

And no, for the FTW class type, you'd be better off with the 650w versions, those top line cards can easily pull far more than reference numbers.

As is, I'm not sure how much of a bonus it'll be, if you have that old i7 970 running 1066 ram as per specs, a 1080ti is going to be pretty much under used.
