Need help selecting PSU

[e22big]

I am innitially looking to buy either NZXT C750 or Cooler Master V750 SFX to replace my old 850 watt CM PSU, someone in my old post inform me that SFX just don't work with ATX case and NZXT C-series isn't ideal. I don't have a lot of good option available right now so I compile a few here and would like you guy opinion on which is the best to buy 

 

NZXT C750 (my innitial choise)

 

THERMALTAKE TOUGHPOWER GF1 750W 80 PLUS GOLD

 

Corsair RM750 Gold

 

ANTEC ANTEC HCG-750

 

ASUS 750W ROG STRIX 80 PLUS GOLD 

 

These are all having a 10 years warranty, cost the same except Corsair RM750 which is significantly cheaper than the others and Asus ROG which a bit more expensive than the rest. If there's significant flaws I am kind of like the look on NZXT C750 but I also value something that can run quietly or in semi-fanless mode. 

 

Any opinion are welcomed

that is pretty good psu.

 

if the RM is much cheaper get that. there are not really much difference between those other than the HCG having issues with high power gpus.

The NZXT C,  Antec High Current Gamer, Asus Strix are all built the same internally (Strix has bigger GAMER ROG heatsinks) other than the fan bearing used...

TT GF1 is the best of the list; however, if money is tight, then we can skip that option. Additionally, some SFX units work in ATX cases if you have an adapter. You just need the holes on where to secure the unit to match. However, CM's SFX units have been having fan problems. Their first revision had terrible fan tuning and whining, and a new batch of them still has the issue.

If the NZXT C is cheaper than the RM, I would pick it up. I am not very fond of the RM series given their cut-down component selection (capacitors, lackluster heatsinks leading to fan bursting at ~90w load, and while I think removal of in-line caps is acceptable for production cost reduction, ripple goes up.) I have seen $60 units with better bulk cap and secondary side output filtering capacitors...Needless to say, capacitors are only a single part of a unit, so NZXT C v RM v GF1 is up to you.

nope they are all roughtly the same price, TT GF1 (gold though not platinum or titanium) is actually slightly cheaper than NZXT C, while RM is the chepest (by a lot)

 

money doesn't matter that much in this price range though, if RM is subpar compare with the rest I am more than willing to drop it

well, guess that's a deal breaker, I am looking for 750 watt PSU exactly because I have a pretty power hungry GPU (3080)

Sounds like a GF1 recommendation to me.

The thing is, Seasonic had a rebranding moment a little while ago. Their prior units (and still Prime Platinum/Titanium units) have OCP problems causing them not to be able to handle transients like on 1080TI, 2080TI, VEGA 64, and by extension, RDNA2/Ampere. You can check the tierlist notes, but those units have been phasing out of production since January of last year, and they should be shouldn't be a concern on what you get...

Worst comes to worst and you got old stock, the unit will just turn off during operation...Then, just return it.
