Is a PSU with 80+ white certificate safe?

Indonesian people here

Would 80+ be alright? Should I buy the 80+ bronze one? I want to build a PC with a budget that is not too expensive.

effiency is not quality. there are decent non certifies psus and decent 80+whites. but it depends.

 

where are you buying from and with what budget

QUOTE ME  FOR ANSWER.

Tier lists for building a PC.

 

Motherboard tier list. Tier A for overclocking 5950x. Tier B for overclocking 5900x, Tier C for overclocking 5800X. Tier D for overclocking 5600X. Tier F for 4/6 core Cpus at stock. Tier E avoid.

(Also case airflow matter or if you are using Downcraft air cooler)

Spoiler

 

Gpu tier list. Rtx 3000 and RX 6000 not included since not so many reviews. Tier S for Water cooling. Tier A and B for overcloking. Tier C stock and Tier D avoid.

( You can overclock Tier C just fine, but it can get very loud, that is why it is not recommended for overclocking, same with tier D)

Spoiler

 

Psu tier List. Tier A for Rtx 3000, Vega and RX 6000. Tier B For anything else. Tier C cheap/IGPU. Tier D and E avoid.

(RTX 3000/ RX 6000 Might run just fine with higher wattage tier B unit, Rtx 3070 runs fine with tier B units)

Spoiler

 

Cpu cooler tier list. Tier 1&2 for power hungry Cpus with Overclock. Tier 3&4 for overclocking Ryzen 3,5,7 or lower power Intel Cpus. Tier 5 for overclocking low end Cpus or 4/6 core Ryzen. Tier 6&7 for stock. Tier 8&9 Ryzen stock cooler performance. Do not waste your money!

Spoiler

 

Storage tier List. Tier A for Moving files/  OS. Tier B for OS/Games. Tier C for games. Tier D budget Pcs. Tier E if on sale not the worst but not good.

(With a grain of salt, I use tier C for OS myself)

Spoiler

 

Case Tier List. Work In Progress. Most Phanteks airflow series cases already done!

Ask me anything :)

1. the 80+ rating is not an indication of quality. There are good and bad PSU's in the 80+ White, Bronze, etc. ranges. It's most important to pick out a good quality unit

2. it of course always depends on the PC you're making. Specifically, the CPU and GPU you'll be using.

 

There is no simple "yes/no"  answer to this question, as we need to know the circumstances too.

Honestly, you should just browse the almighty PSU Tiers master list and pick something that fits your user case / budget, just please don't go too low.

 

Also, be wary of those 80+ stickers; there are a lot of unscrupulous makers that put it there to trick consumers into buying their unit thinking it should be good, when in reality they don't even have the certification - I had to buy one of those in a hurry (a "Hiditec Arctica 600W", only bloody thing they had available at that moment) and it's a steaming pile of dog shit.

edit ... . "white"   230v only means just that the power supply is designed to work only with 230v and not the whole AC input range (no 110v , no 100v). 

 

In order to make a power supply work with lower input voltages, you have to use some components that are capable of handling bigger amounts of current.

If the power supply is made for 200-250v only, then some cheaper components that can only handle less current can be used to save some money. 

 

For example, let's say you have a 850 watts power supply. If it has to work at 110v AC, it has to be able to take in around 1000 watts, so 1000 watts / 90v AC = around 11A of current, so for safety you'd probably want to use components rated for around 12-14A of current. 

If you make it only work on 230v, then you could say 1000 watts / 200v = 5A,  so you could in theory use components rated up to 6-8A, which are probably cheaper. 

 

A power supply is also a bit more efficient, around 1-2% more efficient, when running at higher input voltage. So a power supply could be just enough efficient to pass a certification (ex 80+ bronze means 80% efficient at 20% load, 82% efficient at 50%, something like that)  but may not reach the efficiency required with lower voltage. 

 

It's not a good indicator of the quality of the power supply.  For example, it could be a power supply from a brand name manufacturer, but the manufacturer wants to compete at the bottom end of the market with other brands and cuts everything possible to make the psu cheaper ... removes sleeving from cables, uses regular wires instead of ribbon, cheaper fan,  as little input filtering as required by legislation in that country,  and use cheaper components that decrease efficiency to the point where the power supply would only be 80+ efficient if running at higher voltages. 

 

On the other hand, it could also be some shit no-name power supply, but such shit no-name brands would have no problems lying on the labels and just advertising the model as something better than "white"

White is just 80+ Standard. There's heaps of full range (115V-230V) 80+ White PSUs. Off the top of my head Corsair VS, EVGA W1, and Cooler Master MWE V2 White.

 

I think you might be thinking of 80+ Standard 230V EU PSUs such as the Cooler Master MWE V2 230V.

Quite incorrect information there.

Yeah, I admit I screwed up a bit, I wasn't talking about the "white" but about 230v only models, but I think the actual information in the post is otherwise correct.

Spotty already corrected me, so I didn't feel like adding another reply.

Well, we could add to that. 😄 There's also 230V only PSUs all the way up to Platinum!  (There's a couple Titanium, but they're not ATX)
