fredlaso Posted November 16, 2017 Share Posted November 16, 2017 Hello, I just purchased Dell Inspiron 5675 Gaming Desktop and it came with 460W Dell power supply. I would like to buy Corsair brand I just do not know which would be compatible. I am thinking of a PCU unit between 650-750W. Dell offers me an upgrade for a used one 850W for $230. I do not want to spend that much. I looked at Amazon.com but I cannot figure out which one of your brand would be compatible. If you would be so kind to assist me I would greatly appreciate it indeed. Below are the links to Dell forum with their Power Supply Spec. Ny Desktop has the following Spec. AMD Ryzen 7 1700X 3.4GHz Octa-Core Processor 8GB 2400MHz DDR4 RAM 1TB 7200 RPM Hard Drive AMD Radeon RX 580 8GB GDDR5 Graphics Card DVD+RW Drive Dual Band WiFi 802.11ac + Bluetooth 4.1 Windows 10 Home (64-bit) 460 Watt Power Supply w/ Polar Blue LED Includes: Dell KB216 Wired Keyboard + Dell MS116 Wired Mouse Ports: 6x USB 3.0 1x USB 3.1 Type-C Gen 1 2x USB 2.0 1x Audio Combo Jack 1x 3-in-1 Media Card Reader 1x P/S 2 1x 7.1 Channel Audio Out Expansion Slots: 3x 3.5" bay 2x 2.5" bay 2x PCIe x1 2x PCIe x16 http://en.community.dell.com/support-forums/desktop/f/3514/t/20019321?pi21953=1# http://en.community.dell.com/support-forums/desktop/f/3514/p/20024419/21031446#21031446 Thank you kindly in advance.

Corsair Employee jonnyguru Posted November 16, 2017 Corsair Employee Share Posted November 16, 2017 A lot of people in that forum thread are wrong. They shouldn't be focusing so much on the +3.3V and +5V combined because the PC doesn't need that much power on the +3.3V or +5V. Those rails are mostly there for backwards compatibility. A PC only uses as much power as it needs. It's not going to all of the sudden not work because there's 20W less power available on a particular rail. Judging from the posts in that thread, the PSU is a standard ATX mount and the connector is a standard ATX12V connector, so go nuts with whatever PSU you want.

fredlaso Posted November 17, 2017 Author Share Posted November 17, 2017 Thank you for the info. Would any modular PSU with around 750W work? Thank you. Link to comment Share on other sites More sharing options...
DevBiker Posted November 17, 2017 Share Posted November 17, 2017 If, as jonnyguru mentioned, it's a standard ATX mount and a standard ATX12V connector, any standard ATX modular PSU will work. It's likely that it is a standard PSU. OEMs used to have all kinds of shenanigans with non-standard mounts and connectors but that happens less and less. Turns out that it actually costs them more for the custom designed hardware than using standard, commodity hardware. Still, be prepared for the possibility, however remote, that Dell did something just weird enough that standard hardware won't fit. Link to comment Share on other sites More sharing options...
