80+ gold or titanium psu?

[eldraco86]

my current psu is dying but still usable thankfully since i have to wait until next month to buy a new psu (unless it completely dies). the psus i'm looking at are the corsair rm750x and the be quiet! dark power 13 (looking at 750 watt one). they've mostly been maintaining the same price difference for a while which is about $40 usd.

if they keep that price difference is it worth it to get the dark power 13 over the rm750x? i'm just upgrading the psu.

Gold or Platinum won't really matter. They are both around 85-91 % efficiency rating depending on the load you put on it.

Whats the full PC specs?

They have 850W for around $125

I wouldn't go lower then 850W

gpu and cpu were adjusted due to power draw after cpu upgrade being to high. pushing the rooms' circuit breaker limit. along with ups wattage limit being almost 2/3 of game power load with monitor, modem, and ps4 (turned off) plugged into battery. so need to get better ups. dont feel safe adjusting limit before alarm goes off.

gpu recommends 650 watt psu. can go to 850 watt since both have an 850 watt model.

post the cpuz validation url

asrock b550 pro4 is not very good for high end cpus
it cant deliver more than 150w to the cpu cores

if you plan on upgrading the gpu or using the psu in another build go with 850w

A higher rating only accounts for a slight difference in power efficiency at the wall, difference between gold and platinum rating requirements is ~3% which is basically nothing unless you're using literally thousands of watts constantly.

Not really any point overspending on a platinum power supply, especially in this case

thank you. while i can game for 20 or 40+ hours some weeks. was just wondering if it was worth the $40 usd for the better efficiency or not.

No one needs a platinum or titanium PSU.

normally i would agree but money has been getting tight for me recently. with electricity costing $0.16kwh. was wondering if it would be worth it since i game at least 8 hours a week.

The PSU won't make that much difference when it comes to power at the wall. Not when comparing Gold vs Platinum; if the Platinum PSU is like 40-50$ more, it's not really going to help you save any power over the course of a year. Not enough to even justify that price difference. Now over the course of 5-10 years, maybe. But again depends what kind of consistent power load you're talking about.

What's your full PC specs; a change there might make a difference. Like a more power efficient GPU for example. Or going Ryzen over Intel.

i'm not considering platinum but titanium.and no not uprgading cpu or gpu since i did that this year. i'm just upgrading the psu. only reason i want with a 5900xt over the 5700x3d is i do stream on occasion. sadly 5800x3d was sold out at that time otherwise would most likely have got it.

Only makes a difference if you're in the literal thousands of watts, aka mining rigs

Your PC is usually maybe 450-550 watts at most; a Gold 750W would be plenty.
Paying extra for Platinum or Titanium isn't going to make any differences with a system like that.

Where it helps is when you actually are pulling like 1000+ watts from the wall (like an i9 + 4090) and need the higher efficiency for like 1000 watts or more.

Why they would even sell a Titantium 750W makes zero sense really.
Most Gold rated ones today are approx 88-91%

ok thanks. this really helped out. this was the kind of info i was looking.

That depends on a variety of factors such as how long you use it per day, what the load is and what the local cost of electricity is in your area.

At a full 750 watt load the difference between gold and titanium is 3%, which is 22.5 watts at most.

If both systems ran at full load for 4 hours per day at a nominal cost of 14 cents per kilowatt hour you'd save $4.60 per year and it'd take you about 9 years to earn your money back. It's realistic to use a P.S.U. for that long, if not longer since the warranty is 10 years, but that's assuming you don't need to upgrade above 750 watts.

However for one thing, you're more likely to run the system at half load for one thing. The efficiency differential increases, but the overall wattage drawn from the wall lowers, so you're not saving anywhere near 22.5 watts in that case. For another if you underestimate the amount of overhead you need for upgrades and swap out the power supply prematurely, you'll lose on your investment.

If you narrowed the choice down between the two, I would probably just say to go with the gold supply.

It makes a difference. Gold is 82 to 90 and Platinum is 85 to 92 depending on the load.[www.tomshardware.com] Plus he's talking about gold vs. titanium, not gold vs. platinum. Titanium is above Platinum.

Simple amortization calculation. Lets assume both 850W PSUs and your hardware would consume exactly 425W. Means both run at 50% load.

US Gold efficiency: 90%
US Titanium efficiency: 94%

Effiency = Eff.
Power pulled from Wall socket: AC
Power consumed by PC: DC

AC x Eff. = DC | / Eff.
AC = DC / Eff.

For Gold:
AC = 425Wh / 0.92
AC = 472.22Wh

For Titanium:
AC = 425Wh / 0.94
AC = 452.13Wh

=> The power consumption difference is:
472.22Wh - 452.13Wh = 20.09Wh
20.09Wh/1000 = 0.02009kWh

=> cost per year
Runtime = 8h/week x 52 weeks
Runtime = 416h/year

=> Power consumption difference per year:
Yearly power consumption difference = 416h/year * 0.02009kWh
Yearly power consmption difference = 8.35744kWh/year

Yearly cost difference = 8.35744Wh/year * $0.16/kWh
Yearly cost difference = $1.34/year

Now you can calculate yoruself how many years need to pass for ~$1.50 savings per year to make a more expensive PSU worth the cost:

Price difference / $1.34 = years neeeded for amortization

for future proof i would advise to get platinum 1000w psu
