650W vs 1000W

Recommended Posts

There is nothing bad in getting a higher power unit, only benefits. 

Except for the higher OPP tripping point, since the RMx lacks multi rail. So potentially more dangerous, in case of a catastrophic failure. 

There can also be a higher inrush current, since the caps are larger.

I think the hoomans put their builds here?

Why do you hoomans give your builds a name? Here's my build, which I shall call "Do as I Say, Not As I Do" (seriously, don't get this build)

Spoiler

Ryzen 1500X @3,925 GHz

Cooler Master Hyper 212 Evo + 2x ML120

MSI B350 Tomahawk Arctic

2x8GB Corsair Vengeance LPX 3000 MHz CL15 (Micron B-die) @2933 MHz

Sapphire Radeon R9 280 Dual-X @1120 MHz / 1450 MHz

120GB 850 Evo

120GB Kingston SSD

500GB WD Blue

Cooler Master Elite 430

Seasonic Prime Titanium 650W

Logitech G710 with Kailh Box Jade

Logitech G502

HyperX Cloud

And my laptop, which I shall call "If It's Stupid But It Works" (It can actually play CS:GO at 50 FPS, and Civ V at 25 FPS)

Spoiler

Lenovo Thinkpad L460

Intel Core i3 6100U

4GB (probably) DDR4 2133 MHz

Intel HD Graphics 520 0.3-1.0 GHz

128GB Samsung MZ7LF128HCHP

Corsair M65 Pro RGB (worst mouse I've ever had)

Sennheiser CX 5.00G

And here would be where I would put a picture of my cat. But apparently, images are not allowed here. So take this instead (*ΦωΦ*)

What system are you running that needs 1000w? 1000w is waay too much. Unless you're running CPU that has high TDP and high end GPUs..

You certainly are a certified cat.

Anyways i thought more about that: 1) The 1000w unit is sold by amazon not some rando. 2) Better 0db fan curve 3)Better efficiency at load 4)more ports on the back 5)Better upgradeability 6)free delivery

Better upgradeability

For the purposes of a regular PC, these power supplies have effectively the exact same upgradeability, unless quad SLI makes one hell of a comeback.

 

Also, 1000W = 350W more of bragging rights.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Xeon X5560 - 24GB ECC DDR3 - MSI GTX 650 - some 7200RPM SATA II thing - Ubuntu (at the moment)

Whichever is cheaper, obviously.

 

I only have a 750w unit in my rig because it was on sale. Most rigs need PSUs under 500w. It's price that should win out over Max wattage.

There's no way in current condition that you will need a 1000 watt psu, unless you would fill all 4 PCIe slot with 2080.

BUUUT, getting lower power psu usually for cost consideration.

IF 1000watt psu is the same price as 650watt, i say just get it.

For the amount of watt it will use, comparatively the same, it will output the amount of what the system's demanded.

If all the same (components, heatsink, fans, casing) there's no benefit.

Pretty logical for the price drop as nobody wants 1000 watt psu right now, the only market it has was miners, and now miners are gone.

 

But wait, i think i see the difference, the 1000watt has more ports, thats a deal for me (although i won't use it).

All wrong.

 

Because the difference in Efficiency is negligable with more modern Designs. 

The semi-fanless stuff is based on Temperature, NOT load.

Better efficiency depends on the Curve and you also loose Efficiency at lower loads as well.

Better Upgradability is not entirely true either...

Correction:  The fan controller uses load AND temperature.  The OP AMPs used to measure current for OCP also reports back to the fan controller.  The reason an MCU is used instead of a standard thermistor fan controller is because there's a rather complex algorithm programmed into it to tell the fan when to spin and how fast it should spin.

1000 all the way. 750 is petty, I do have one as a coaster though.
