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.

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

There is no future proofing in that, More likely that he will be worse on the efficiency scale and pay more money in electricity. Quite the opposite of what he wants to achieve.

you are not drawing 1000w off the wall if your pc is not using that much.
i been using 1200w platinum for many years. peak power draw is around 650-700 on reader

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

thanks did not know the formula to calculate the difference. tried a few search terms and couldn't find it. granted was tired and was pass bedtime so brain only operating at 10% :P. but seriously just got too tired and gave up and made that post.

Do not forget that the factory warranty on the platinum and titanium are usually greater/longer than the gold but it really does not matter much if you buy from a good brand - I remember in 2021 when EVGA had a huge discounted sale on their website up to 50% off or so during December but have not looked since so idk if they still have them.

Use pcpartpicker.com or another reputable site to calculate power draw and see what you really need for a PSU (I usually add a few more things, such as more storage and others, that I think that I would add onto the system over the course of about 5-7 years and take that into account as well for calculation purposes).

No one needs a platinum or titanium PSU.

I got my "Platinum" PSU because it was 20$ cheaper than gold and on sale for 60% off.

yeah no. for me to hit peak efficiency i would need 500w draw on psu. heaviest load i had before undervolting and switching to eco mode was about 460w on the ups. which still has the monitor, pc, modem, and ps4 (usually turned off) all plugged in the battery of the ups. so i'm not using that much to make 1000w even worth it for the price over an 850w. to be clear the program that my ups has to let me see what the wattage load and voltage load are track everything plugged in the battery. so i would think i'm already at that 50% threshold for efficiency. and i rarely if ever can spend more the $300 before tax on any single part.

If you not willing to spend on decent gpu then yes, you won’t need 1000w psu

why you need to wait a month?
I means whats a psu? 100 euro?
how is that an issue when you have halve a years income in savings as you should?

but as for whats the better buy... well..

1 how much does electricy cost where you live..? 40 / that price per kwh meas you need to save that much in powerdraw before the more expensive one is worth it.

3 whats your standard draw
. psus don't offer a stable efficiency but an effiency curve.. depending on % of maximum drawn.. while peak effixiency is very close betweem gold and platinum.. at very high otr very low % drawnd the gap is much greater.

if your system only draws say 400w peak and 250w most of the time the efficiency gap will be bigger.. than if 600w peak and 500w most of the time

but as a rough estimate you can presume the gold will use 2.5% more electricity than the platinum.

[_I_]

platinum/titanium may be worth it if you are running 1000+ pcs for a data center

for an average user gold/plat/titanium will make no difference

i'm in the u.s. the reason i need to wait a month is don't really have the money to spare atm sadly. while i can get this month its going to hurt the wallet really bad. also last month spent nearly $700 usd (before taxes) fixing my pc. unfortunately wasted about $50 taking it in to a local pc shop that diagnose and repair on a 2nd diagnose. but at that point was frustrated enough that i paid them to do install of windows and update bios since originally the boot drive became corrupted. and also got the 5900xt and had them install it to make sure everything worked.

I would have done it for free - lest not forget that Chipset Driver now either.

couldn't figure out what was wrong after getting back the first for the corrupted boot drive. which i didn't know could happen to storage drives. don't know how it happened but one of the vga power cables came disconnected enough to not give power between them finishing that first diagnose and me getting it back. bought a new drive and installed it my self. was getting to the point i would think about throwing the pc at the wall.

especially since i had to take it in the same day as a game i been wanting to play came out for the 1st diagnosis. and i only got it back after the 2nd time i took it in before my birthday. and i barely had the money to spare for it. so i can get it this month but only if it dies, because then i would have no choice. and i was planning to get the 5900xt originally this month or next during all the sales (most likely with new mobo too).

Some MOBO ATX cables can be really sticky (ASRock especially it seems), so I use a tiny bit of Dielectric grease on the interior sides of the connector - I have heard that sometimes heat can cause connectors to become loose but I have never seen it personally happen regarding VGA cables but I have seen this ATX cable getting sticky (perhaps from heat or fitment) which also can cause no power/no boot situations for reasons I am unsure of.

The AMD Chipset Driver I am interested in seeing if the "experts" installed that as well for you seeing that they installed the BIOS and these go hand-in-hand usually.

There is a reason custom cables exist

PSU "custom" cables also come with a risk.

I feel you.. repairs and especially labour costs hurt badly..
you rather save that money for your next pc!

-still personally never in my life came to a point I not had savings and could not afford to replace something when it breaksm. even when still on minimumwage.. though while on minimumwahe an unespected 3000 euro dentistbill followed by a broken pc bill of 2000 .. did make me have to go into debt for a few 100dred for 1 month when when it too broke + eat very sober the next 2 months.
-good financial skills and diciplinr helps a lot
*but I also know how much worse usa is when you fall you fall so much harder and deeper.. less a safety net than here..

but ok usa has much cheaper kwh prices than the nearly 60 eu cent per kwh I pay. (only like 4 dollarcent in most usa states and lile 1.2 dollarcent in texas))
with such low rates your computer needs to consume an insane 40.000 to 135.000 kwh before the gold rated one starts getting cheaper..
that would mean using the pc for 180000 hours minimum or 20.5 years without ever turning it off.
so budgetwise go for the chesper gold rated one..
