Hello,
I want to buy a PSU but I live in Iran and here the usual known brands are really expensive.
We have a brand that's been known for its PSU and Cases called "Green". Their budget and lower-end PSUs are made by Channel Well Technology Co. and their better PSUs are made by High Power Electric Co., Ltd. I really don't know much about these OEM companies.

They have recently released 2 new series of PSUs, 1 semi-modular Gold series and 1 fully-modular Platinum series.
Gold series: GP500B-HP+ ($73), GP600B-HP+ ($82), GP700B-HP+ ($96)
I can't seem to find any certification on the 500W variant but the other 2 have the certifications up on the 80 Plus website.
Platinum series: GP650B-OCPT ($100), GP750B-OCPT ($120), GP850B-OCPT ($145)
They all have their certifications up on the 80 Plus website.

Now onto the question. Both the 500W and 600W variant only come with a single daisy-chained PCIe 6+2 cable! Isn't that weird? Like what if I get an Nvidia graphics card that needs 2 8-pin PCIe cables? Will it be fine? It seems like most Nvidia graphics cards don't like daisy-chained cables as JayzTwoCents showed in one of his videos.
3 of the above PSUs come with 2 daisy-chained PCIe cables: GP700B-HP+, GP650B-OCPT and GP750B-OCPT. Like wtf why only 2 cables on a 750W PSU??? Will that ever be fine for a SLI setup that needs 4 PCIe 8-pin connectors?
And the last one GP850B-OCPT still comes with only 3 daisy-chained cables. Like even that doesn't have 4 seperate cables!
Anyway, I wanted to buy the 500W but couldn't find its certifications on the 80 Plus website so I want to buy the 600W but that only comes with 1 daisy-chained PCIe cable! So I wanted to step up higher for the 700W but the 650W Platinum is really close at only $4 more lol. So I'm leaning towards that one! What do you thing about these? Do you think they're any good at all?

Tho the PCIe cables on the Platinum series are 16 AWG if that makes a big difference.

Here are some links:

Platinum series official page: <removed>
Gold series certs on 80plus.com: <removed>(600W), <removed> (700W)
Platinum series certs: <removed> (650W), <removed> (750W),<removed> (850W)
Cables: <removed>,<removed>, <removed>, <removed>

yah that's better than i was thinking at first. pretty normal specs for a psu of that wattage.

12v amps are full rated power which is ideal. channel well makes decent psu's most of the time. if you can't find a ton of people claiming they are junk in local stores, then it is probably a safe buy.

if they are popular and sell well with few reported issues, then it is probably a decent unit. any unit will have a few problems, that's why everyone has a warranty dept., but it sounds like a good buy for the money. i can't find anyone who has reviewed one so it is an educated guess.

the cases remind me a lot of antec cases. just thought i'd throw that bit in :)

The fact that we probably haven't heard of them before (I certainly haven't) and your description of the daisy chained cables makes me wary of you buying from them. The PSU is the absolute last component you want to cheap out on, since a low quality PSU could damage every component in your computer. The amount of unknowns involved with that manufacturer leads to my conclusion that you should just take the plunge, do your research, and spend a bit of extra money to make sure that you're not going to damage any of your components due to a low quality PSU.

Those certifications do not necessarily mean they use high quality materials, it's just its efficiency rating (which is usually a good indicator, but not all the time. EVGA uses 80+ certification and some of their PSUs are garbage).

Hi and greetings from the US! I've never seen 2x 6+2 PCIe power connectors attached to one cable before. PCIe cables have a standardized maximum wattage rating: 75 watts for 6-pin, and 150 watts for 8-pin. If the PSU has two of them on one cable, then they just doubled the wattage of the cable itself and output connector. Now whether the video card itself can handle that is another story. I have not looked into it. The old hardware rule of thumb is stick to the standards. The standard being one separate 6+2 pin PCIe cable for each input needed in the video card.

Channel Well is a very well known power supply OEM for major PSU brands like EVGA and Corsair. Their quality variates widely however depending to the quality tier of the PSU. I have never heard of "High Power Electronics" but a quick search shows it's mostly an OEM for non-US PSU markets. Unfortunately there are no reviews from trusted websites like JohnnyGuru that are PSU specialists for "Green" PSU reviews or another vendor PSU with that OEM company listed. I just wouldn't trust anything that does not have a professional review.

Is it at all possible for you to buy a Corsair or EVGA power supply in Europe somewhere?

Alright I forgot to say a lot of people here use their budget PSUs and they are reliable so they're not garbage.

And if you look at their Official pages they claim they've used very high quality components inside these but idk much about the things they've named so idk if their claims are true xD
But they claim to use Japanese "Nippon Chemi-Con" and "Rubycon" caps which I think are high quality?
They also have 130 Months (10 years + 10 months) of guarantee so makes me think they might be just as good as the other high quality PSUs? Other than those daisy chains.. But TBH I'm never going to go SLI nor Crossfire. Worst case scenario would be a Vega 64 lol

Honestly tho EVGA PSUs are hard to find and way more expensive.
Be Quiet, Seasonic, Superflower etc. are non-existent.
Only Corsair and some Cooler Master PSU are available but for example a Corsair RM750x costs $200 lol and a Cooler Master V750 just under that at around $190...

it is not uncommon at all to have 2 6+2 cables on the same cable. in fact it is pretty much normal. the wires are rated for the power draw and i have never seen anything reliable that suggest it is a bad idea. that jay2cents guy is a joke and i don't really like his videos at all. if he said intel makes the i5 cpu, i'd double check to be sure. that's how little i trust his stuff. clickbait in a video for the most part.

in the old days it was potentially an issue if the circuit the cable was on was not strong enough (the old multi-rail problems). but that has not been an issue for a long time. it's possible some junk brand may still overload one rail and leave the other one under used. but no reputable brand has done it in a long time.

bigger concern for me is that a 750w psu only has 2 x 6+2 connections. that tells me a lot about the psu and is enough for me to avoid it. a 500w psu can handle that easily. so a 750w one that only offers them is telling you right away that the psu can't actually give 750w. it's most likely 500-550w or possibly less

Yep. I was for whatever reason thinking he was referring to *two* 2x 6+2 connectors on one cable. Every PSU I've bought over the past six years has had two separate PCIe power connectors on one cable. One cable, one GPU connection. That's what I meant.

Sadly there's no official shipping to Iran from any kind of European retailers. Just some private shippers that will cost a fortune. But as I said people use these Green PSUs since 2000s here and they're fairly reliable from what I know. Never heard of them dying or anything tbh lol.
But I wish JohnnyGuru would be able to get their hands on one of these Platinum PSUs to test out and review lol But I believe it's as hard as me buying a PSU from Europe lol and he has probably never even heard of it.
But yeah it'd save me a lot of money to just buy this 650W Platinum PSU vs those Corsairs and Cooler Masters...



Of all those PSUs in that list I found an affordable one from tier 3:
Cooler Master G650M ($100) costing exactly as much as the Green Platinum 650W but it actually looks its got less quality lol

And 2 less affordable ones:
Cooler Master V650S ($123) same price as Green Platinum 750W
Cooler Master V650 ($130)

In all honestly they "look like" they have less quality?? :D
Just if there was a good review of these Green ones :/

If that's the case then the 750W PSU actually has 4*8-pin PCIe cables?

Do you think the 650W Platinum ones that's fully modular any good then? If daisy chains are totally fine and it even has 16 AWG cables.
I mean it can't be worse than a tier 3 Cooler Master G650M? 130 months of Guarantee vs 36 months.

Oh alright then I guess daisy chains are totally fine just as Buildzoid tested them on Vega 64. He sadly didn't have any Nvidia graphics card at hand and couldn't test them tho so I was going by Jayz's testing lol
That was my main concern on why they'd do it that way on a high-end PSU as they call it. But seems like that's how everyone does it :D

Channel Well makes their budget PSUs while their higher-end PSUs like these Platinum and Gold ones are made by High Power Electric Co., Ltd.
But yeah as I've said this Green brand is very well known here for its PSUs and Cases and is fairly reliable but I wasn't that sure about their higher-end PSUs and those daisy chains got me wondering xD Dammit Jayz you got me worried over nothing lol

Anyway thanks for the help everyone! I appreciate it!

i've learned that if something is really true, it'll be on many sites. someone may find it first (like tom's discovered the amd problem of pulling to much power from the mobo pcie slot) but many quickly investigate and confirm the issue.

if you find only one person/site saying something and no one backing it up, then it is likely false. youtube is based on how many watch your video not how true it is. clickbait is rewared heavily in that format and lots of folks decided views was more important than integrity. hence clickbait crap like ol 2cents and others (he's not the only one)

Yeah totally agree. I never really take Linus, Paul's and Bitwit seriously xD They're just like e-celebs of the PC community.
But Jayz is usually more sensible but I guess he's still not on the level too be trusted too much.
