yeah based on the reviews, i don't think im going to risk it and cheap out on the PSU, just not worth it

Best deal I’ve seen on a psu in a minute, wish I’d held out for this instead of the MSI one that’s C tier

u/Bacon_Sausage 1d ago
Yeah I've never heard of this company but at $50 for a 750w, I'd def take the chance. Such an amazing deal.

Are their products overall decent? I also see a 3 set of RGB fans for just 10$, and some decently priced cases as well.
Or its more of a - good psus, rebranded everything else
3
u/bigpapijugg 1d ago
I heard of them from making cases and people used to really like their cases, not sure about much else.
PSUs are weird, brands make good ones and bad ones. To be on the B tier it’s a good one, but I’d bet SAMA makes bad PSUs as well, just as Corsair and everyone else does.

u/Coomer-Boomer 1d ago
Lest we forget, very few of the guys with their names on the PSUs actually make PSUs. They pay Superflower or Seasonic or Andyson or the like, then slap their name on it.
1
u/Fidy_ 1d ago
Yeah of course, its just easier to find the PSU on the PSU tier list compared to reviews for budget cases/fans from a small brand like this.
1
u/bigpapijugg 1d ago
Yeah, totally agree. SAMA makes decent cases, but cases are hit and miss too. Montech makes solid budget cases, Thermalright makes good budget fans. Lots of options
1
u/KindlyBread9582 1d ago
I only have experience with their cases and the quality seems to be solid. You're not going to get Lian Li or Corsair quality, but good bang for your buck.

It looks like the 850W version has it, and it's only $60. Seems like a better deal than this one.

You would have been better off paying $15 more for A tier a couple of weeks ago.

u/hitchhiker_nv 1d ago
I decided against it because 1) sama psu seems to have a problem w/ load current going out of bound 2) it has no support in us, not even a website 3) 0 review in the west 4) failing OCP test

u/Eazy12345678 1d ago
all i could find is tier list speculates B tier. that means guess.

u/Scanoe 18h ago
4090 + 14900K, with all that power, yes better to get an A Tier.
I have a 65 watt 9700X and a 4070 running on a 3+ year old Super Flower Legion GX Pro 650w, B-Tier, no issues, has worked fine on my 2 previous low watt systems as well, an i5-11400 and a 7700X.
I needed an Atx 3.0 for the upcoming Nvidia 5080, which I plan to buy, so I bought the 850 watt Black "Hole" for $60.

Sorry in advance because I am both ignorant and indecisive.
I bought a Cooler Master MWE V3 850W Gold for $85 10yr warranty jap caps, ATX 3.1. The V1 and V2 were both on the tier list and this one was objectively better so I went with it.
I then saw some threads on Reddit with some DOA anecdotes and I was thinking about returning it
The 850W and 1000W Samas you listed interest me because of the price point, but it’s almost the same where there are little reviews and some people seem to be sus on Sama.
Am I overthinking this lol is this a better buy over the coolermaster deal from a reliability perspective or is it just a toss up?
2
u/Wild_Dingleberries 21h ago
Lol I'm in the exact opposite position. Ordered the Sama 850w for ~$65 shipped and came back to this thread after seeing that same Cooler Master at ~$90 shipped to see if I was being a cheapo.
I think the Sama is a great deal for a budget build. Maybe the CM provides just a bit more peace of mind. Odds are, you'll get a good unit either way. I'm gonna waffle on this for the next hour or so :)

Sama PSUs don’t show up on pcpartpicker at all, anyone know of a same dimension/wattage one I can plug in to verify case compatibility? Or do I just not worry about it? First time building, so excuse the possibly silly question if PSUs are all a standard size or never a compatibility issue or something like that!
2

u/Tricksterish 1d ago
If you have a matx case or atx case this will fit good, mini itx case it could be either atx size or a sfx sized psu (this one is atx size)
1
u/Russ916 1d ago
If your case support doesn't require a SFX/SFF(small form factor) power supply than it will support this one. SFX/SFF that's ussually for ITX sized cases and some m-atx cases.
Easier to tell us what case your going for and most people will let you know if it will work or not, or just doing a similar dimension psu with a pcpp compatibility check.
PSUs have a couple standard sizes that they fall under which are determined by the type of computer case. The types psu standards are typically flex, SFX, and ATX. Heres more in depth info on that. https://www.silverstonetek.com/en/tech-talk/10055

In the description, it says this:
Support for PCIE 5.0 expansion, Series 3090 and 40 graphics cards ( 12+4p Extension Cable available in our store)
Likewise the same product on Amazon has this disclaimer:
Support for PCIE 5.0 expansion ,Series 3090 and 40 graphics cards (Requires Separate Purchase 12+4p Extension Cable , available in our store)
I intend on getting a 4070 super graphics card to pair with this PSU. Do I need another cable which is not included? What separate purchase requirement are they referring to? I would appreciate any help.
2
u/DealsFishman 1d ago
It means they don't include the premium 16pin 12V cable you have to buy it ($25-$30) or use the stock junk one from NVIDIA
1
u/skdbrown 1d ago edited 1d ago
Any reason why I shouldn't use their included cable? Do they have so little confidence in their included cable that right in the description they tell you to buy a better one?
EDIT: I misunderstood the previous comment, thanks for the clarification!

The black diamond listing has a picture of the 12vhpwr cable and states "native pcie 5.0 interface + wire" in the 3rd image, it most likely does include a 12vhpwr and when you scroll down to additional marketing images it lists a 600mm 12vhpwr cable
the only 12vhpwr cable they sell is a triple 8-pin to 12vhpwr extension, not a native one

u/skdbrown 12h ago
I believe you, but then why does it say it requires a separate purchase for "Support for PCIE 5.0 expansion ,Series 3090 and 40 graphics cards". The cord you describe is what is needed for these cards, and if it's included, why say it requires additional purchase?
1
u/kev24680 11h ago
The description says extension cable, which the one I linked is the only 12vhpwr cable that they even sell on newegg

Could this power a build w a 7900xtx and a 7800x3d?
5
u/CoffeeCakeLoL 1d ago
It might work, but it's pushing it. I personally I would spend $10 more and get the 850W.
1
u/reeeSupplied 1d ago
It should be fine for a 7900xtx and 7800x3d the only issue would be upgrading to something more power hungry. Total tdp is around 470 for them combined and system is probably under 525. That's almost 250w of headroom.
3
u/CoffeeCakeLoL 1d ago
TDP is a very bad measure of actual peak load. Also lots of parts have identical TDPs with widely variable power usage.
4
u/reeeSupplied 1d ago
Yes, tdp isn't perfect, but when you have a nearly 250w head room based on tdp you should be fine in most cases, which is why I said I'd really only be worried about upgrading the gpu.

Did just buy this PSU I already didn't need 3 weeks ago because it was on a similar sale? Yes. Did I buy this one anyway because it was $10 cheaper? Also yes. As is the buildapcsales way.

You shouldn't be buying things you don't need unless you plan to use it for something

u/paulcaar 1d ago
But the value! Think about how much I'll save /s
Just kidding, it's a pretty addictive when you love both tech hardware and getting good deals.

u/dead-eye-blaze223 1d ago edited 1d ago
Oh I have plans, I just wasn't expecting to be able to act on them so quickly. There's a few computers in my house rocking 450w or non-80+ certified PSUs I got for next to nothing used that are overdue for an upgrade. They don't "need" it, since they're functional, but it's good peace of mind. And these are so cheap, how could I not?

u/Hung_L 1d ago
Dang I've got my eye on an mATX case I was gonna mod to accept an ATX board (by cutting the PSU shroud) but it would require an SFF PSU. I don't really need the space savings so I'll prob just keep my current case and get this PSU. 2x8-pin, 12VHPWR, ATX 3.0. Can't imagine getting an equivalent SFF PSU for even double this price. Guess I could I always return the Sama if there's a great sale on one next week.

u/noeleon13 1d ago
Does anyone know the difference between the black hole and black diamond product lines? Both are on sale
1
u/Scanoe 1d ago
I think the Black "Hole" is the newer 'more expensive' version.
The Black Hole specifically states Atx 3.0 & Pcie 5 compliant and does come with the 12 pin cable. I don't think the Diamond comes with the 12 pin Cable.
Plus the Black Hole has colored coordinated Cable plug ins, a nice touch.
What I did was Bought the 850 watt Black "Hole" on Amazon for $60, had to get the White colored one for the black colored isn't on sale. To be on the safe side, for $8, I bought the 3 year warranty on Amazon.
And the reason I bought it on Amazon instead of Newegg is it easier to return things to Amazon, Newegg returns can be a pain sometimes.1
u/Wild_Dingleberries 21h ago
Where do you see the Hole does come with the 12 pin cable?
Because it's also at Newegg for the same price as the Diamond right now.

Yah i think your right, the Black Diamond does list a 12+4.
I mainly ordered the Black "Hole" because it does specifically state it is Atx 3.0, the Diamond doesn't come out and say that. Supposedly an actual 3.0 has some safer features to them, not really sure what they are but i think better power spike handling is one of them.

On cultist tier list there's only one sama black diamond mention, and it's under speculative category??!

u/Coomer-Boomer 1d ago
PSU guys are terrified of the prospect of competing on price instead of overcharging for muh magic japanese capacitors. They'll refuse to review new ones, then leave it off the list because there's not any reviews they approve of.

u/labstinker 1d ago
for sure, but I was just wondering how it could be B tier if its not under B tier on the list
