Hi, so I am in the market for a new PSU, it has to be 80 plus gold (electricity is expensive), and at least 650w.
Preferably want something with a 2/3+ year warranty, as I won't finish my studies for the next 5 years.
What would you recommend and why?

Thanks.

Either of these two.
 
Super Flower Leadex 750W 80 Plus Gold


Or have a look at a PSU tier list and decide for yourself



Stay away from raidmax 🛑

Heard about raidmax, stayed away from that for sure, especially with this build!

Looked at that, it looks really great(Superflower 750w), just couldn't wait for stock to arrive.
Thanks for the advice:

Ended up with an EVGA G2 1000w gold plus, literally was R300 more than the leadex 750w.
+ factor, finally a completely modular PSU😁🙃.
All in the same tier, tier 1.
 
To late to the party! I thought those fancy shoes made you quick! :p

really enjoying my seasonic. I don't think it ever heats up enough for the fan to come on

Am I missing something, platinum is 2% better, does it make a big difference or not really?

Their build quality is better, they look better IMO and their PSU's are smaller, at least the 1200W I had was.

Well ye they are slightly more effecient. So draws less power form the wall but PC's dont cost a lot anyway electricity wise. I mean at 300w / 4hrs per day is really not much electricity.

However platinum PSUs generally have better components. Quieter fans, better quality capacitors that will take a lot longer to die on you.
With all this loadshedding I feel a little better having a plat PSU incase the power turns off while my PC is on

The way I see it a ridiculous 1000-1200W platinum rated PSU can go for as low as R1500. Why save R500-700 to downgrade to something like a 650 Silver/Gold rated PSU or even a 750. At 1000-1200W you may not be at your PSU's efficiency curve but you will literally never have to upgrade it and it'll remain your most high end component in your system that you can upgrade your CPU and GPU around as you please.
 
I have the Corsair HX1200i PSU and I can honestly say if running a high end gaming rig that PSU is very much sucked into boredom as it never exceeds 40 degrees hence the fan never kicks and hence it's actually a huge overkill. I initially bought the PSU for running two Vega 64 in crossfire as EVERYONE was going on about the minimum watts I will need and once I fired up that crossfire I could shat myself as both Vega's and my whole PC never drew even more than 750 watts of power at full load...it was a WTF moment. Sold the 1 vega and my 750 watt PSU to a friend and now I have the 1200i in my PC just sniffing puffs of electricity to my hardware.

Really no need for high watt PSU when you only play games...well that's MY opinion and I can see the power draw when I play BF 5 that is quite a demanding game.

My power draw for my rig in sig is around 380w on full load while gaming. This includes 2 monitors a shit load of fans (19)However I havnt overclocked my 1080ti and I chose my CPU because it has a low TDP.

So 380w to a 750w PSU is perfect.

I got too good of a deal to refuse though ;P

So you and your shit load of fans is one reason for us getting load shedding :unsure: :ROFLMAO:

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!! 🔥

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.

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

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.

M@tree2 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.
