Haha the point was that even with all that shit plugged in, the power draw form the wall was still very low. So 1200w+ PSU's are major overkill unless you have 2x AMD graphics cards lol.

You can blame AMD for loadshedding and general fires in our country!! 🔥

LMAO....hence then I sold the 1 Vega (and the fact that crossfire is useless) and even when I ran just 1 Vega with the 750watt and checked the power draw, it was roughly 400 watts for my complete rig on 100%....WHY people were going on about 850watts needed for a Vega 64 was beyond me. Also, I got the HX1200i at a give away price of R2200....couldn't let THAT one slip...LOL

When picking a PSU you want it to sit at around 40-50% load at your peak typical usage (eg gaming) pretty much all PSU's are at maximum efficiency around that usage.

So it makes no sense to get something like a HX1200(Just epeen?) on a system that draws around 300w.

Seasonic/Enermax/Superflower all great. I believe most of the top EVGA/Corsair units are Seasonic rebrands.

Hmmm, I was advised by many people to have a PSU that runs roughly 70% at full load, not more and not less.

Why not less though?
70% seems a little to high. You don't want to overwork those little capacitors on the PSU.

I suppose id rather be safer than sorry, also another reason I don't overclock my GPU

I guess depending on the PSU you choose, its important to look at it's efficiency curve(usually on the back of the box).

So my Superflower runs at around 50% on max load which equates to 92%+ efficiency.

I have NO idea why not less....I guess it's got to do with that "Pinky and the Brain" moment.
I don't think my PSU fan has EVER come on because it NEVER gets hot enough to trigger the fan...so I am running "green" I guess...LOL

Actually, running a PSU at a very low load can put strain on it, but we are talking 200 watts or less.

[email protected] I'm glad you found a great PSU - it's complete overkill but it's a great PSU so you should be fine for the next 10 years.

The points raised by the other members about the PSU being happiest at 50% load and platinum efficiency being a good thing mostly because components that they put into the PSU being superior, are absolutely correct.

Platinum efficiency isn't something to get hung up on, it's the capacitors that go into making the PSU that are better.

I tend to stick to 650 watts for a gaming rig because that's more than I'll ever need and the price isn't expensive. Gone are the days of the GTX480 when you had a small furnace in your computer, burning a hole in power consumption.

Hence I went with a corsair 750watt back when I had a single GPU before I bought the whole crossfire idea and upgraded because of that. Even with today's gaming rigs many you can run with a 600w PSU but I just like to have that extra buffer if any needed....now running a single Nvidia GPU, I can actually supply Eskom with a little bit of power while gaming...LOL

Agreed it was overkill, no lies there, but it's future proof for the next generation of Intel I9s:ROFLMAO: (300w at max load, rumoured to be, at least).
So platinum is really just caps and a huge amount of money more!
EVGA G2 1000w was R2k from Wootware, and has a 10yr warranty.

Haha glad I'm not the only one who bought a gigantic Corsair PSU because the price was irresistible 😅 but when a 2 y.o. HX1200 was going for the price of a new 650W gold, I couldn't resist.

EVGA G2

Admittedly my last two pc's had a CoolerMaster and now a Corsair in, both Gold Rated, have been exceptionally happy with both. The high end Corsair's are amazing. Don't let the pre-boot sequence scare you after the power was off though, it does some sort of check. Scared the hell out of me the first time it did that.

I think if you EVER decide doing some decent custom loop cooling and RGB you are well equipped with sufficient power though.

I recommend superflower aswell. Stellar build quality and modularity at a good price to rival some of the bigger brands. If I'm not mistaken they are also the OEM for alot of manufacturers like EVGA. But honestly, I have one myself they are primo

Edit: The gold units ship with a 5 year warranty!

I already have a decent custom loop, EKWB 3.2 ddc xtop pump, 1x360mm rad, 1x240mm rad and fans to match those rads...
So hope 1000w will be enough🤦‍♂️.

Got my HX 1200I a year old for R 2.1 k but still a nice PSU you have there.

My current PSU does this as well, thanks for the head up!

Will be more than enough - my new loop will have 4 rads, 2 pumps, two res's & a shitload of fittings!

I managed to get a Corsair RM750i on the forums for R1500, nearly new.

It’s stuck in South Africa until I can come visit and take it back.

It may be going on for 6 years+, but it still works very well and is still under warranty.
