My 7-year old Seasonic just kicked the bucket after a few recent upgrades. I think my upgrades actually decreased my power usage so I just think the PSU was done. I’d like to get something new to replace it. My current rig has a 4770K overclocked to 4.7GHz and a RX-590 running stock clocks. It’s in a Bitfenix Prodigy case so size is important, as is at least semi-modularity.

I’d like to stay sub $100 and, if possible, sub $75.

On another note: is there anyone that repairs these? I opened it up hoping I’d see an obviously burned component but everything looks fine.

The EVGA 750 G3 comes highly recommended & is a solid mid range - mid price choice. The current crisis is affecting stock of everything, however, and your available options limit your choices. Some of the recommendations you will see depend on how long you can wait before purchase.

Otherwise this Seasonic unit is pretty decent.

I would personally find a good model to stick with and shop around for the best price available on that specific unit. This is just a primer to get things going.

if you could identify what went wrong and bought the parts and did it yourself it might make sense to fix but the price of a new unit is going to be less than what someone would reasonably charge to diagnose and fix it (assuming it's even fixable).

Seasonic Focus/Focus Plus, Fractal Design Ion+, Corsair HX series, and the Antec Earthwatts Gold Pro series are all solid.

Do I need a full 750W or it just not worth getting smaller PSU’s these days? Physically, the smaller the unit is, the easier my life is with routing cables and whatnot.

Give us more details, man. What could have possibly killed a 450W Seasonic PSU?

issue is only on specific GPUs (Vega 56/64 and Asus Strix 970 IIRC) and it's fixed with the replacement PCI-E cables, the power supplies are fine.

the rename is just a rename and the new models come with the updated cables in the box, IIRC.

because PSU quality is dependent on system components?

darn, I always forget that.

We know the main power drawing components at least. Shouldn't need more than a good 650 watt PSU so long as you don't buy a junk tier unit.

My “daily” computer has seen very sparse usage over the past few years since I have a Microsoft Surface that I use for work and I haven’t gamed in like 3 years. I‘ve been sick and quarantined so I decided to get the new COD and start playing games again.

The Seasonic is 7 years old. I was in the middle of playing Modern Warfare and the computer just turned off. Wouldn’t turn back on. Pulled my MB, processor, and memory and put it on my test bench with an AX1200 and it started right up. Put the Seasonic on the bench and just like in my daily, it wouldn’t boot.

A few days prior I had replaced my 7970 Lightning with the RX 590 but the 590 should pull quite a bit less power, right?
