Corsair SF750 SFX power supply $169.99

Good price for SFX.
Looking to build a sff next year, so been following a bit. Good for those in the market

Great deal for an SFX PSU. The best was last year I was so excited to build in my NEW Lian Li o11 Dynamic only to realized I couldn't use my ATX Power Supply.

Decent for a platinum rated SFX. I'm looking to eventually upgrade my 600W SFX. But I think I'll wait for a 850W to drop.

its SFX guys, thats why the price premium. not your run of the mill ATX 750W

Comes with sleeved cables as well.

Not sure if the downvotes are from people who can't read or just hate SFX builds

This is kind of the de-facto SFX power supply for ITX builds... I'm replacing an SFX-L PSU in my NR200 so that I can fit longer GPUs.

This 750W should handle up to RTX 4080 without issue unless you're running a *really* power hungry CPU.

Nah,last I heard the 4080 runs on thunderbolts. People tend to overate their psu needs by a large margin that it's rediculous. I was told the recommendation for a psu by many people was 1000 watts 10 years ago and here we are. Still nothing to this day can use that much juice, even accounting for headroom.

yeah people shit their pants when i tell them i run my 6800xt on 650W (recommended 850W) and 6700XT on SF450

Considering I have gotten a 1000 watt PSU for under $100 before I will pass.

ok I'll bite.

Which 1000W SFX PSU did you buy for $100

Mostly can't read, or don't know what SFX is.

Guys did I over-purchase for my build?

I got a 850W for:

5800X3D @ 105W
2 sticks of ram + possibly 2 more
two nvme + possibly 1 sata
b550
expected RX7800XT or 7900XT @ 300W, maybe 7900XTX @ 360W

PCPP says 570W-630W depending on ram and GPU

Edit: people don't understand the pain in the wallet for building small form factor builds

SFX power supply = short cables for a SFF case = will probably not work in your mid-tower unless you pay at lest $30 for extensions to the cables.
It comes with a mounting bracket for non-SFF builds.

It was cheaper at Canada Computers last week.

I just built a Lian-Li A4-H20 just yesterday with an extra SGX650 SFX-L (from a NZXT H1 chassis) but I wish I had a SFX instead. The case has enough room for a SFX-L but you lose a bit of space to bundle extra cables and such. Every bit of space counts.

What a great case, it feels so solid and no space is wasted anywhere. But you really have to choose your components well. I could barely get the tubes inside without stuff bulging out.

Good luck fitting that PSU inside a mini ITX case.

How much did you get your lian-li H2O for? I have been debating on that case vs nr200p

Who said I needed a 1000 watt PSU for a mini ITX case? I never knew I said that.

This is awesome. An SFX psu deal and I'm reading posts about people getting psu's for $100 and random case reviews. Gotta love RFD!

Well, certainly you could have gotten away with a lesser power supply. My build above has a 650 and I will never get over 450W.

SFF is a pain in the wallet but I love small powerful computers. It's more challenging to build in but that's part of the fun, it feels like more of an achievement once it's built, and optimized. I'm still occasionally thinking if I should route the cables differently in the build I did above
